How data visualisation techniques like Infographics, video, audio can help make sense of Information

For those who regularly visit my blog you will know that I run a small in house video production service for a very large research company. We have been using Infographics and illustration for some time in order to make better sense of information for client deliverables. It is clear that data and information can be simplified but often it still requires a degree of deciphering in order to fully consume. In the past the use of video has brought to life a simple verbatim or a timed reveal of a chart with a voice over lead the viewers eye around the visual. We now look to combining these techniques in order to produce the most powerful client deliverables through illustration, animation, audio and video.

On the GfK TechTalk blog we have begun a series of posts in order to show off these approaches, starting with an Information Overload graphic. Watch this space to find out what we are up to.

Adobe Premiere Pro – The difference between Track Volume and Clip Volume

If you are used to using Final Cut Pro you will no doubt prefer to control your audio channels in the timeline rather than on the effects tab. At first this appear difficult if you use the button to the left of the timeline depicted here you shall reveal further controls in Adobe Premiere Pro.

This will allow you to control the levels from the timeline over time which is very handy if you have a soundtrack or voice over that needs to be taken in and out during your edit. Often these level changes will be clip dependent, meaning that if you move the clip around the point at which the levels need to change will remain the same. Sometime these changes in sound level will be relevant to the edit and if you move certain clips you will still require the levels to change at that point. Using the drop down here you have access to show clip toggles or show timeline toggles. Remember that clip levels works on that clips audio independent of the timeline and the timeline audio works on the timeline audio independently of the clips.

Add keyframes at the playhead using the black diamond next to the track or by using the Pen Tool.

Adobe Premiere Pro – Selecting audio or video independently in the timeline

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.

Simply 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.
