AVI exports are uncompressed and fill much more than they should, often up to four gigabytes. If it reaches those four gigabytes, Source Filmmaker can't export the rest of the video, meaning that the video file is incomplete and corrupted. (This is your issue.) If it doesn't reach four gigabytes, it still fills more than it should.

MP4/MOV exports require QuickTime, which is a security risk for Windows.[www.us-cert.gov] Even if they didn't, they'd still be too dark and saturated or too bright and desaturated (depending on compression codec), along with compression artefacts, so they still wouldn't be good options.

(It's okay to export AVI/MP4/MOV videos from other programs; only Source Filmmaker has these bad AVI/MP4/MOV implementations.)




On the other hand, image sequences export individual images and a sound file, and then it's up to you to combine them into a video yourself. There are a few different image formats, but I recommend PNG as it's a widely-supported, losslessly-compressed format (while JPEG is lossy-compressed).


After exporting an image sequence and sound from Source Filmmaker, you have to open them in a video editor, set the frame rate correctly (e.g. 24 frames per second if that's the session frame rate), and export it as a video with whichever format and compression settings you want.
Almost any video editor will work, except for Windows Live Movie Maker as it can't use an accurate frame rate.

You can then experiment with different video formats and compression settings, to find a good balance of high quality and low file size.
