I can get a correct filesize(not too small) if I convert to 23.970 FPS on both the first AND second pass using vdubmod. If I convert to a lower FPS on just the second pass I get about 60% of the filesize I put in my second pass settings. However, converting it to 23.976 on both the first and second pass makes my rip a bit bigger, by about 10%-15% from my intended filesize. If my max filesize for one 100 MB TS encode with original AC3 audio was 51200 KBs, it'll wind up being 54,556. This doesn't sound too bad, but it managed to make an encode that was supposed to be 1423360 KBs into an encode that was 1,839,769 KBs. and I have been using the same video size gordianknot gives me in virtualdub for the video size for second pass each time.
Right now what I am doing is loading the TS files into mpeg2repair, having it output one large ts file, putting that into dgindex, putting that into gknot, and putting that into vdub afterwards.
If I keep the FPS at the default 59.*, the filesize is exactly what I tell xvid it should go for in the second pass settings. However no standalone or portable which I encode it for can playback something at such a high framerate. I tried converting to 23.976 frames per second on the finalized copy using direct stream copy and saving to a different AVI, but it messes the video up. gspot will show it as being 23.976 frames per second, the length of the file will be the same as before, but it will play slowly and choppily. The bigger filesize doesn't bother me that much - not knowing why I am getting a bigger filesize is driving me nuts, though.
I tried changing quants from h.263 to mpeg, packet bitstream and not packet bitstream, unrestricted and AS@L5, xvid 1.1 and xvid 1.0.3, but nothing does the trick. :( autogk can convert and output the exact filesize I ask for, but autogk also limits me far too much in what options I have. While it's nice for movies, for HDTV files I like to have a bit more flexibility.
Since it is converting to a lower FPS that gives me an issue with the size of the encode, and I cannot find a way to fix it, I am thinking that if I can find a way to decrease the FPS of the original source HDTV file BEFORE making a d2v of it, then I wouldn't have to worry about it later, and could avoid all of these issues. Is there a way to convert HDTV MPEG2 files to a lower FPS?
I have no problem with my encode that I make when converting to 23.976 on both the first and second pass. The audio is muxed nicely and it plays correctly. I just don't know why it is doing this to the filesize. Any suggestions would be highly appreciated.
Thanks in advance for any suggestions.
