When purchasing a video camera or choosing your project settings in your editing software you may come across the dimensions followed by an i or a p for example 1080i or 1080p. This stands for interlaced and progressive scan.

The difference between the two are as follows. If you imagine you video is built like a brick wall, in layers known as fields. In an interlaced video each field is offset not dissimilar to the brick wall. You have probably noticed this during moments of fast motion where you see lines like a comb at the edge of the moving subject.

Interlaced video should be deinterlaced for your final product. In Final Cut this is done by applying a deinterlace effect, in premiere pro it can be done as your send your media to Adobe Media Encoder.

Interlaced_Video

Progressive scan video already has the fields aligned resulting in a much crisper image and less things to think about at edit. Be sure if you are working with progressive video not to deinterlace your video when you export it. It will reduce the quality.

Progressive_Scan_Video

If you wish your final video to be displayed on a computer monitor then always deinterlace your video or use Progressive.

You can also De interlace video in Quicktime Pro, Window > Show Movie Properties > Video Track > Deinterlace

Quicktime_Deinterlace

It is often necessary to scale and move the images you have brought into your timeline. Often you will want to create a slow zoom in, zoom out or pan across an image to add a little movement to your video and have it look a little less like a slide show.

If you familiar with Adobe After Effects you will find this very easy as it’s a process of adding keyframes at start and end points to inform Premiere as to where motion should begin and end.

Start by creating an image in photo with dimensions (Understanding dimensions) bigger than your frame dimensions. Bring it into Premiere and drag it down to the time line. You will see the image appear in the window on the right.

Now place your playhead where you would like the animation to begin and then with the clip selected click on the effects tab in the first preview panel.

Adobe_Premiere_Pro_Effect_Controls

Effect_Control_Add_KeyframeYou will now see a mini timeline appear for your particular clip. Locate the symbol that looks like a stopwatch, next to the scale controller, click and you will see a keyframe appear on the timeline. Now move the playhead to your proposed endpoint either on the main line or the mini one, again hit the keyframe button and you will see another black diamond appear, signifying the end of the motion. Note that as you move the playhead away from this diamond it is no longer black. You must have the playhead directly on the frame in order to effect it, otherwise another keyframe will be generated. With the playhead properly aligned change the scale numbers to 80 percent. Now drag the playhead back in the main timeline and play your video, you should see a slow zoom out.

Scale_Image_Premiere_Pro

Change the scale to more than 100 percent for a zoom in. Exactly the same theory applies to motion the only difference being that you must change the x and y axis in order to create a pan.

It is possible to place as many keyframes as you like on the timeline in order to create more complex movement.

There are two main ways to control the sound levels in Adobe Premiere Pro over time outside of a simple constant gain, expositional fade transition.

Firstly, it is not straight away that obvious that this can be done in the timeline in much the same way as in Final Cut Pro and the use of pushpins.

Adobe_Timeline_Toggle_OnLocate the button to the left of the timeline and highlight it. You should now be able to place pushpins along the levels line.

Place the playhead where you would like your fade or gain to begin and then click the grey diamond where you see the text “Audio” to the left of the timeline. You will notice a pushpin / keyframe appear on the audio track and the grey diamond turn black.

Move the playhead and the diamond will turn grey again, place the playhead where you would like your fade to finish and add another pushpin / keyframe in the same way. Grab the level beyond your second pushpin / keyframe and drag it down.Premiere_Pro_Audio_Timeline

You have created a gradual fade over time.

The second way is much the same as creating motion with images and takes place in the effects tab. If you have the Show Clip Keyframes drop down selected, you will notice this in the timeline to. With your clip selected place your playhead where you would like the fade to begin.

Levels_ControlExpand the levels controls under effects and locate the stopwatch symbol. Press this and a small black diamond (keyframe) will appear in the clip timeline. Drag the playhead to the end of the fade and repeat. You should now be able to reduce the levels beyond your second keyframe without affecting the sound before the first. The diagonal fall between the two signifies the fade over time.

Audio_Effects_Tab

In Final Cut pro you are probably used to toggling on and off this button in order to break he linkage between audio tracks and video tracks. It is not as obvious in Adobe Premiere Pro although once you know how it makes sense and it might even be easier to incorporate the action into your editing.

Apple_Alt_KeySimply hold the alt Key while clicking either the audio or video track. You will notice only one is selected, you can now move this independently from the other, delete a track or copy and paste it. Note if you move the track a indicator will appear showing just how many seconds and frames you are out of sync from the original partner.

Screen_Resolution_DimensionsResolution seems to be a subject that baffles a lot of people with different platforms (TVs, monitors, mobiles) different mediums (video, print, web) and also different pixels per inch which effects the overall size and quality of your image.

Let’s start with pixels per inch and keep it basic. Pixels per inch is the amount of small dots of color per square inch. As a rule 300 pixels per inch is the bare minimum for print while 72 pixels per inch is suffice for web based output, admittedly as PC monitors resolution has increased over the past few years I often find myself producing an image with a 150 px per inch in order to produce the better results. It all depends on your intended output. For video output I did a few tests in order to confidently advise you for best results. I created two identical images in Photoshop with the same physical dimensions, I used the Film and Video presets found after hitting new. I produced one at 72px and the other at 300px and saved them out as a png, I then brought the two images into Adobe Premiere Pro in separate time lines, I exported them using the same full quality DV setting and then oped them up side by side and played them. I asked my colleagues which they thought was produced with the higher res images and they consistently couldn’t identify it. In this case it seems that the resolution of the input file does not noticeably effect output.

See (URL Coming Soon)… for more information on export settings using Adobe Media Encoder and other such programs.

Print Resolution
With print resolution as mentioned earlier, 300 px is the minimum px per inch for a decent quality. When setting up your workspace you should be concerned with the physical size of the output, for example A4 is 210 mm x 297 mm with 300 px. Photoshop has presets for most print outputs so have a look and familiarise yourself with these.

Web Resolution
When I began studying my Design for Digital Media Minor, the standard size to construct a website was around the 800 px wide. The resolution of computer now vary and this size meaning that the websites began to look very small in the browser. By analysing google analytics user traffic it soon became obvious to design you site to a greater width. Today popular website width sizes are above 1000 px wide although many more dynamic CSS driven layouts will be sized based on a percentage of the browser window for consistency. As mentioned before you graphics should have a pixel resolution of 72 px per inch and above.

Video Resolution and Dimensions
There are two aspects to take into account here. The production of graphics for your video projects and the resolution you wish to output your video for the intended viewing platform. The production of graphics I touched upon earlier so let’s get to know video dimensions. The landscape has changed recently with the emergence of multiple mobile platforms alongside the popularity of High Definition on the consumer market.

Television Dimensions
There are 3 main television dimensions you should be aware of, there are variations but combinations i.e. widescreen (also see …) but use these as a starting point.
DV Pal, 720 x 576
Consumer HD, 1280 x 720
Pro HD, 1920 x 1080

Blu Ray and HDTV Dimensions
720 x 576
1280 x 720
1440 x 1080

Other Device Dimensions
There are many other devices now on the market that are all geared up to display video so often we might want to output at a format suitable for these.
Mobile Phones (3GPP)
128 x 96
176 x 144

Other mobile frame dimensions, 176 x 208, 176 x 220, 208 x 320, 240 x 320 and 352 x 416.

Web Video Dimensions

Widescreen HD 1280 x 720
Widescreen SD 640 x 360

Myspace Video

Yahoo Video
320 x 240

(Dimensions may vary slightly)

Aspect Ratio
At this stage I just want to distinguish between what i mean by dimensions and how it differs to aspect ratio. All the dimensions I have touched upon up until now have referred to a 4:3 aspect ratio, this means for every 4 vertical pixels there are 3 vertical pixels. Most will have come across widescreen by now in their digital lifes and this has an aspect ratio of 16:9.

Time for some basic editing technique and I’ll try to make as much of this as possible applicable to all editing software where possible so you can go away and practice. In order to produce a professional standard of video output there are certain guidelines you should adhere to. Programs like iMovie make editing easy but are confusing with offerings such as page peal transitions and sepia effects etc, which are often completely unnecessary. No matter how tempting it is you should keep your editing simple, so here’s a brief guide that can be applied to many editing platforms. I work using Adobe Premiere Pro and Final Cut Pro so apologies in advance to other users.

Capture and Import

First thing you need to be confident about is getting your footage onto your computer. Often the assumption will be made by the client that the footage will be available for viewing minutes after the shoot when in reality this is possibly one of the timeliest processes. With changing formats this process differs but for those still using tape you will need to find your capture window. On Premiere Pro this is under File > Capture.

premiere_pro_capture

In final cut pro it is found under File > Log and Capture.

final_cut_log_and_capture

On consumer products such as iMovie choose imovie_import_from_cameraFile > Import from Camera. If you are plugged in using a FireWire cable you should now be able to operate your camera or deck from you desktop. If you have not logged your footage and have a handy list of time codes you will have to manually grab the footage. To do this que up the section of the video you desire, press play and then record. Your clip will appear in your projects library with the rest of your media. Be sure to name your clips well to locate them in the future and if you have a bunch of clips that belong together, create a New Bin by right clicking in the library and name accordingly. If you have HDD camera you should first have the drivers and codecs installed on your machine, in theory you should be able to plug in your hardware and then drag and drop the files across into you projects folder. Once or if your file are on your local machine you can click File > Import to import your files or in most programs drag and drop them to your library.

The Timeline and Tools

Understanding the timeline and a few tools is essential for editing. Obviously the timeline is the linear holder of your chosen clips but it is important to remember that you can stack up your video and audio to create a dynamic edit. This is used for things like titling the respondent in a clip or laying down a buzz track. You can add more tracks as and when you need them by right clicking one of the tracks to the left of the timeline. This can also be done for multiple audio tracks. Dragging and dropping your clips from the media library to the timeline is simple, you can then play through the clip by hitting the play button in the right hand viewer or by hitting the space bar, notice that as your clip plays the scrubber or play head moves along the timeline. You can also grab the play head with a hold click and scroll along the timeline. For frame by frame accuracy use the left and right arrow keys on your keyboard. Whilst editing, for those who are used to the arduous wait for final cut to render your timeline it is not vital in Premiere Pro. Although playback will appear blurred, you can build an entire edit without rendering the timeline and export it without a problem.

Audio Transitions

Like video transitions keep your audio transitions simple and use them to mainly improve the continuity of what you hear. You should always lay down a buzz track anyway but transitions can help smooth the audio between clips. In order to ensure you leave yourself the option to use transitions, try to direct some dead sound before and after the clip when shooting by telling your actors or respondents to count to 5 and then begin or to pause for 5 seconds after each take. (where possible) Use fades at the end of clips to reduce the glitch sound and gains at the beginning of clips, use constant audio transitions to smoothly link clips, although be aware that audio from one clip might be heard in the next and not be appropriate.

Manipulating Sound

When transition fall short is when you need to affect the audio often along the timeline, this is often brought about when using a sound track. You may wish to bring up and reduce the track before and after some dialogue for example. In final cut pro this is very easy using pushpins in the audio timeline, you merely pop a pushpin where you want the change to begin and one where you want it to finish, followed by moving audio level up or down. In premiere pro however, it is a little more difficult. The best way I find is to select your clip in the timeline and then click the effects tab. Drop down the levels control and make sure your play head is at the point you want the effect to begin, add a key frame and then slide the play head to where you want the change to finish, in the same way as final cut you can now drag up or down the audio using the yellow line or the level slider. Do make sure your key frame indicator is black when you make the new change using the slider, otherwise you risk automatically adding a key frame in the wrong position.

Video Effects and Transitions

As aformentioned, using transitions should be a limited and controlled affair. As a rule if there is not a reason to do, or use something then don’t do it, you will just confuse the viewer. If it is appropriate and correctly timed a straight cut will do, if this is too hard soften it with a cross dissolve or a fade to or from black. Apply the same principle for video effects, don’t use one unless there is a specific reason for stylising your video, it will just look weird.

video_transitions

Effects Tab and Key frames

As aformentioned in the section on audio,  you can effect things over time using the effects tab, the most common example of this would be the need to scale some over time or move the position within the frame. For this we would use the motion and position drop downs. In the same way as we affected the audio track place the play head at the point you wish to begin your animation and add a key frame, then place the timeline at the end point and add another key frame. Whilst the play head is at the point of the key frame your will turn black. Change your values here or effect the video in a drag and drop manner in the viewer on the right hand side. This technique is especially good for window in window video. As soon as possible try to get into the habit of changing co ordinates or percentage in the effects tab rather than manually dragging and moving the video in the preview pane. Have a notepad in front of you and record notes as you may need to replicate the size and position of another clip later on in the edit.

Colour Correction

I shall first emphasize the important of getting colour right during the shoot, more on that in ‘Basic Filming Technique’. You can however, digitally fix your image and your controls can be found under your video effects. I won’t go into massive detail at this point but I recommend learning about brightness and contrast, saturation, curves and colour balance. Practice on images in Adobe Photoshop or Google some tutorials as you may waste hours trying to fix an image that could be corrected in seconds with a basic understanding of some image control options.

Cropping

Not a topic I originally intended to include here but as someone asked me today how to do it and with a growing trend for recording on screen tutorials, it will be handy to know to neaten up your work. Again the crop tool can be found in your video effects. Drag and drop it to your clip and manipulate the left, right up and down in the crop drop down in the effects.

One major point to remember is that Adobe Premiere Pro’s settings or preferences sit independently from the system preferences on the machine. This can often be confusing at the early stages of playback. I can’t emphasize enough how important it is to get your project settings right at the beginning to avoid not understanding why premiere is behaving in a particular way in the future. The first few times you begin a project check each setting independently until you are familiar with what each one does, also be sure to understand the folder structure, which I shall talk about in a short while. Let’s take a look at the new project settings. Unless you have double clicked on a project you will not avoid seeing the open or new project screen. Select new project and you will be faced with the first of two opening screens, let’s look at each setting separately. Firstly choose New Project and you will be faced with the first of two options menus.

Adobe Premiere New Project

In the first new project window leave the Action safe and Title safe areas as is, next to Display Format be sure this dropdown is set to Timecode, Capture Format should read Quicktime but will be different if you are using a windows PC. Next set the Location to the location of intended project folder (See folder structure below) and then name the project something convenient. I recommend something searchable so you can find files easily as your project portfolio builds.

Premiere Pro New Project

Next swtich the top tab to Scratch Discs and you will see the options below. Set all to Same as Project (see Folder Structure below for details) Now click on OK and move onto the second set up window.

Premiere Pro Scratch Disks

Under the Sequence Presets tab select the native video format you have been working in or your intended output if you intend to output to a format of a lesser dimension i.e. Mobile Device. If you know what you would like your first sequence to be then name it accordingly. I shall go into the benefits and uses of sequences separately.

Premiere Pro New Sequence

The majority of the settings under the General tab are governed by your choice of setup on the previous tab. You should not need to change any of these settings.

Premiere Pro General Settings

Again you should not need to touch the settings in the Tracks tab unless you anticipate needing to add more video tracks to your timeline or output your projects audio to 5.1 surround sound. Otherwise leave these set to 3 tracks of Video and Audio set to Stereo.

Premiere Pro Tracks Settings

Click OK and Adobe Premiere Pro creates your project.

Folder Structure
As I mentioned before I like to keep all my files in one place just in case I want to put the project on a hard drive and work on it at home. Also working on projects across multiple user set ups on an operating system can cause errors. Files that reside in a users documents folder will appear offline signed in as another user and will be impossible to reconnect. For these reasons I set all my Scratch Discs to Same as Project. This keeps everything together but the folder can soon get cluttered once you have begun capturing a few videos. When begin a project I drag and drop a folder structure comprising of the following folders, images, after effects, sfx, buzz tracks, music, voice over etc download the example project to see how I have set this up. It also means that once you have populated a particular folder you can drag the file into your projects, creating a new bin and maintaining an efficient structure within your project. I also create a new bin for assets created from within premiere such as titles and also for every scene, cutaways, gv’s, chapter, camera etc so that I can immediately ring my clips as and when I need them.

Capture Device
Setting up the capture device or video camera can bring about a few headaches. Premiere recognizes most firewire decks and cameras but if you see a black screen in the capture window, check your settings. You can find the Settings on the second tab on the capture window under the Device Control section. Be sure on the dropdown you see your device, if not restart the program with your peripherals plugged in and you should achieve success.

Fortunately Premiere seems to be keeping up to speed with all HDD cameras to. Most require you to install additional drivers or codecs on your machine but once installed allow for a simple drag and drop to your projects and playsback in their native format with no need for a further conversion.

Example Adobe Premiere Pro Project (413)

Now see Basic editing technique

This is the first in a series of guides on Premiere Pro. Up until now I had been an avid Final Cut Pro user and always considered Adobe Premiere Pro to not quite be a professional standard editing platform. Perhaps my judgement was unfounded as I had only limited experience using the editing software but my new job meant that this would my new primary edit suite. Armed with a Mac Pro Dual Quadcore I got stuck in and once I got started I found many pros and cons with the platform, this is what I noted down as I made the change.

First let me touch on what I consider to be the main pros and cons of the software’s. For me premiere pro biggest asset is it’s seamless integration with the other adobe products. I have cs4 and in this most of the niggles associated with bringing unrendered files such as psd’s and aep’s has been ironed out. A hefty after effects file will slow down the display of an image in the preview pane but if you can live with this the time saving benefits are worth it. The other major time saver is the ability to drag and drop differing video formats to your project, place them in the timeline and not have to convert the video to the projects native video format or even render it out before previewing. Adobe has not seemed to complete the cross program synergy though at a crucial point. As you come to export your final piece premiere passes the project adobe media (the program we used to use merely to encode our flv’s. Unfortunately exporting a video file to full quality pal DV produces poor results especially for projects with text titling and linear shapes and effects created within premiere pro (more on this in a later post). Final cut on the other hand outputs perfect quality video.

Windows and Mac – There are some differences between the windows and mac versions of Premiere Pro that you should be aware of. Firstly when capturing video the files are saved as the operating systems preferred video. Mac saves as .mov and Windows saves as .avi. If you are hoping to export your files to be used directly in a Powerpoint Presentation on a Mac then you will struggle, there is no export to WMV option as there is in the windows version and the Mpeg formats are not supported in powerpoint. I shall write a separate detailed blog on my workarounds in this area.

Quicktime – I believe it is a necessity to have Quicktime Pro installed on your computer to save frustration with Adobes video Exports. I tend to export to the highest quality possible in Premiere and then re export them for purpose using quicktime. A bit long winded but I don’t have to do this for every export, as I mentioned it often depends on the graphical content of the video.

Making the change – There are a couple of pointers that will save you some time. With regards to making cuts in the timeline, unlike FCP there is no button for toggling the linkage between video and audio off and on, instead hold down the alt key as you make the cut or drag the clip around the timeline independently from the sound. Also another major difference is the ability to edit sound in the timeline by simply adding pushpins. For those familiar with After effects they will have no issues, simply click on the effects tab next to the source tab effects_taband drop down the volume control menu followed by the level dropdown, place your scrubber in the timeline where you wish to begin the effects on the sound and click the stopwatch iconstopwatch_button this adds a keyframe and indicates the beginning of your change. Scrub along to where you wish the loudest or quietest point to be and add another keyframe. While the small triangle is black adjust your volume you should see the volume level in the effects pane reflect your changes. This is a skill you can also apply  to motion and scale changes over time, and can also be useful in getting your head around the motion graphics program After effects. Any static graphical elements to your projects I would fully recommend building in Photoshop to the exact dimensions as your project and not resizing in premiere pro. These are the main things that I had to go looking for as most other differences were pretty intuitive or even the same as in Final Cut Pro. I’m sure there’s more I haven’t discussed so just ask in the comments box below.
