The AVI output uses a lossless compressed codec by default. I have videos in the standard US format 23.976 (24000/1001) But on output I can only coerce it to (23976/1000) which causes problems when matching videos after using other programs on the output and reimporting it into my project. The export has the same number of frames as the inport, but on the timeline does not match for large exports. This has been a problem for numerous versions of this video editor and is NEVER fixed.

24000/1001 is the standard for US DVDs and is supported by other US video hardware. Curiously exports as MP4 or uncompressed are correct, so it is only in the AVI export.

You may ask why use AVI. This is because the video is passed through several other video procesors before creating the final product. AVI default codec exports are lossless compression which saves space. By doing this artifacts due to multiple lossy conversions are avoided.

There is also a display problem for the 23.976 fps video. In the middle of the clip sometimes the display shows the image of one of the next neighbor frames, and when exporting it as an image, the wrong frame is exported.
