Is there a way to get my file size down?
I tried encoding with Xvid, and kept getting very minor fading problems - such as the fade into black wasn't as smooth as it could have been. I tried many things to solve this, and to no avail.
I did, though, just encode from virtualdubmod using Divx, and it makes it look a lot better. However, the file size is huge - 120mb. Any way I can get this down?

Did you compress your audio too?
If you did, you can try to post-process the video to make it more compressable: http://www.animemusicvideos.org/guides/ ... tqual.html
or, encode it at a smaller resoultion:

Fade-to-black is known to be an exceptionally difficult case to handle. A lot of codecs really barf on it.jediphoenix wrote:I tried encoding with Xvid, and kept getting very minor fading problems - such as the fade into black wasn't as smooth as it could have been.

Once you've got your filesize down (maybe by compressing audio or lowering encode resolution) you can try to tell XviD to use more keyframes (I-frames) in those problematic areas.
I forgot how to do that -- haven't used XviD in a while -- but I'm sure there's a way.
Alternatively, you can also try x264 or some other H.264 codec. H.264 includes a bunch of stuff to more efficiently handle fades, among other things.

Re: Is there a way to get my file size down?
Interesting, when I encoded my AMV with MPEG-4 SP, I had problems with fades where a lot of orphan frames at the end of the fade (which are black in the Xvid encode) would show up. I should try to re-encode with MPEG-4 AVC and see if there is a difference. Although ultimately, I suppose I should re-edit the video to get rid of the offending frames...trythil wrote:Alternatively, you can also try x264 or some other H.264 codec.

I'm unable to change the quantization type from H.263...trythil wrote:Fade-to-black is known to be an exceptionally difficult case to handle.
