I've been encoding some anime episodes, using Gordian Knot and the excellent [DVD/ac3 audio --> Divx] tutorial on this site. Most things have been going well, and I'm getting good quality. The only problem is that the file size of the finished .avi seems to run out of control--I set the target in GKnot to something like 230 or 240 MB, and it shows the video file at around 190 MB and the audio file at 40 MB at the bitrate/resolution setting stage. However, the final files have come out at 280 and 290 MB after encoding, which is a little too much. I've used the DivX 5 codec with 2 passes, neutral bicubic compression with Inverse Telecine, in accordance with the guide as much as possible. The final dimensions, after setting the compression ratio in the 40-60% range have been 448 x 336 and 512 x 384, not excessively large, so I'm not seeing why the files are coming out so far above the estimates. Is there anything else I might be overlooking that's causing these sizes to jump so much? Sorry for the relatively newb question; I tried to include as much technical information as I could. P.S. Original source is NTSC DVD, 29.97 FPS, frame type varying between Progressive and Interlaced.

I'm not sure if this relates to you, but it did remind me of what just recently happened to me. I set Xvid to encode a file for 2 passes. I set the target size to 1GB. By the time it had finished it's first pass, the size of the file was 2GB! that's twice what I had selected. This was not what I expected, but I forgot that this was the FIRST PASS. It must have been doing a bit extra to get good data for the second pass. When I started, and finished the second pass, it was right on target for about 1GB.
