Video format in Captivate 9

To add a little more... Video formats have to components; the codec and the container.

AVI, for example, is a container. An AVI movie can be compressed with a variety of codecs.

MP4 is indeed diverse as it can be a container...and there is also an actual (variety of) codec.

What Rollin suggests above is correct - you want an MP4 video (container) with the h.264 codec.

MP4/h.264 is the globally supported HTML5 format to - so an easy way to see if your video is formatted the proper way is to just drop it onto an open (current) browser window. If the browser gives you the option to immediately play it, it's likely MP4/h.264. If it's not, the browser will try to download it, or ask you to pick a player.

If the video plays right in the browser, it's probably fine and the issue may lie elsewhere.

If it doesn't, running the video through Adobe Media Encoder is a good solution to try to convert the video to that proper MP4/h.264 format...and as Rollin notes, be sure the dimensions are proper for what you need (AME likes to use presets so be sure they're correct for what you want).

Hope that helps

The .MP4  video container is a very diverse format. The first thing I would check is that you are using an .MP4 format that Captivate can handle. I would recommend re-encoding the file using Adobe Media Encoder. Make sure the re-encoded file is H264. While re-encoding also make sure the video resolution will fill into your project.

If the H264 MP4 file doesn't work, try re-encoding to .AVI just to see if it will work.
