I didn’t realise that this was an unknown to many but often there is a need to pull things out of PowerPoint for alternative uses rather than put them in. This is often the case for me when produce video reports where the findings have been visualised in PowerPoint. So, it’s as simple as this, File > Save As > under the naming form fill change the drop down to png or jpg and hit save, you will then be prompted current slide or every slide, choose every slide and each slide in he deck will be saved as a separate picture or image.

If you just require an element if the slide you can right click and save as image in much the same way.

Top tip,
If your output proposed use is a higher quality than the resolution of the ppt you can often scale up your deck to A3, any vector graphics will be re sized and the quality of the output increased. Go, File > Page Setup and adjust the page accordingly.

Unfortunately there is no means to simply pause a video on the first or last frame to get that still to motion effect you often see when multiple interviews are shown on screen at once.

I have found the simplest way to achieve this in Adobe Premiere Pro is to create stills by exporting a tiff then re importing it into you projects portfolio.

Begin by aligning and resizing your clips on the timeline (see how to scale video here) in the order you wish them to appear. At this stage you will see black before and after the clip. Place the playhead on the first frame of the video you would like to begin on a paused / still frame. Choose File > Export and select tiff, be sure on the next drop down to export the tiff in the aspect ratio you are working in. It will make lining the image up a lot easier later. Export as usual using Adobe Media Encoder to the correct folder in your project folder (see setting up a project here) import the file back into your project and place it on the timeline prior to your clip. Adjust the length and play through to see the effect. If you need to scale the tiff do so to complete a smooth still frame to motion effect.
