Ive done a lot of work with video in PowerPoint. What is the resolution leaving AfterEffects? Is the resolution more than you will need for your delivery format. When I work in AE, I'll generally do a dynamic link with Premiere Pro and use the Media Encoder there. What is the resolution of the screen you are giving the presentation on? All of my videos are encoded to 1000 pixels wide for full screen viewing.
These are just some lessons I've learned, usually in very bloody ways. If they are helpful, great, if not, thats OK too.
- PowerPoint on OS X = .mov, PowerPoint for Windows = .wmv; you can link a .mov file in windows, but its not as integrated. Ill have a copy of both when I give presentations in case I need to use a Windows machine
- If you want the full screen look, never use an insert box on a slide, it will make it smaller. Rather, delete all short cuts on the slide and go to the menu and do an insert that way.
- Full screen for PowerPoint is 1000 X 750 pixels (4:3 aspect ratio).
- Do not make videos bigger by resizing them in PowerPoint. This will make them look like CRAP. If you want it bigger, encode a bigger version. Again, the max size by default settings is 1000 X 750. If the video is not 4:3 aspect ratio, then make it 1000 pixels wide and put it on top of a black slide
- If you need to make a video smaller (in pixel size) then you ALWAYS hold shift to lock the aspect ratio, then resize. NEVER stretch it on one axis.
- Always have a backup plan if it crashes on you
- If using a NLE (e.g. iMovie) start with a black screen (just a suggestion). The reason is that encoded video looks bad when frozen. I start with a black screen and a 1 second fade in Premiere Pro, but a similar effect is in iMovie.
- If streaming off of USB, make sure the bitrate of the move does not exceed the USB bus speed or the thumb drive capacity. Many cheaper drives and older computers cannot stream fast enough. When possible put on the HDD.
