VS7 Skip Problem

Post by mirry26 »

Nature of the problem: For some reason when I put a track in the timeline, the program will a.) not allow me to shorten it and b.) also won't play the track when I hit it to play as the entire video in the timeline. Instead, it skips right to the end of the track and stops.

The file is an avi file, according to gspot it uses the Xvid codec, and is about two minutes long. I don't know if maybe the system has a problem with Xvid? For a while I was also getting a complete error message that said: DirectShow Engine could not find specified media, or something along the lines of that.

If anyone has any idea about what's up, please help!! Thank you!

The simple answer that, despite the .AVI extension, an XVid clip is in reality a highly compressed mpeg-4, and VS7 and 8 cannot handle mpeg-4. VS9 will with a plug-in which is free to registered users.

AVI is a carrier format which can disguise a variety of properties. Full, uncompressed AVI is huge (around 65 GB per hour). The special variety of compressed, but lossless, AVI developed by Microsoft for digital cameras, DV/AVI, is also large, but five times smaller at 13 GB per hour. A number of other codecs also produce files which can be given the .AVI extension, but which in reality are highly compressed and lossy - but still high quality - versions of mpeg-4. These include DivX and XVid which are usually associated with squeezing an entire movie onto a CD (as opposed to a DVD) with reasonable playback quality. There are a small number of video cameras which apparently now use mpeg-4 format, and the DVDs produced using their output, also in mpeg-4, can be read by a handful of stand-alone mpeg-4 DVD players. The latter can also read DivX and XVid DVDs, I understand.

Wow, thank you for explaining that to me. It helps a lot! Guess I'll just have to upgrade sometime.

Thanks again.
