You have 2 options:
Reencode the audio track and squeeze it to fit your 25fps video. There are tons of audio tools that can do it.
The other option is changing the framerate of the video. You can use VDM for that. Changing the video's framerate is a lossless procedure. Maybe you'll need to add delay too. You can do all these using VDM.

I just downloaded the 1st sample. Look at the fields by using just Separatefields(). This source is really 29.97 fps! There is just lots of aliasing. This improves things a bit, but I think you need a stronger antialiaser: Code: | DGDecode_mpeg2source("I:\videos\samples\junkboy\VTS_01_1.demuxed.d2v")
AntiAliasing(method="eedi2")
#-- function AntiAliasing(clip clp, string "method") { method = default(method,"nnedi2") o = clp oi = o.Assumeframebased().AssumeTFF().SeparateFields() dbl = (method=="nnedi2") ? mt_Average( oi.SelectEven().NNEDI2(field=1,dh=true),oi.SelectOdd().NNEDI2(field=0,dh=true), U=3,V=3 ) \ : (method=="eedi2") ? mt_Average( oi.SelectEven().EEDI2(field=1,maxd=4), oi.SelectOdd().EEDI2(field=0,maxd=4), U=3,V=3) \ : mt_Average( oi.SelectEven().NNEDI2(field=1,dh=true),oi.SelectOdd().NNEDI2(field=0,dh=true), U=3,V=3 ) dblD = mt_MakeDiff(o,dbl,U=3,V=3) shrpD = mt_MakeDiff(dbl,dbl.RemoveGrain(11),U=3,V=3) DD = shrpD.Repair(dblD,13) final=dbl.mt_AddDiff(DD,U=3,V=3) return final }

Thanks for taking a look and for confirming it's a 29.97 fps source I'll try out the AntiAliasing function you gave and I'll go through the AA functions/scripts I've got off Doom9 to see which does the best job.

I've got a much smaller filesize (444 MB instead of 745 MB) using GKnot to encode a satellite TV recording to XviD AVI. I haven't used any matrices, yet the bitrate is 707 and not the 1200+ that GKnot predicts. Is this because it's already compressed for broadcast? This is the file I'm working from: This is the result: Total Size (MB) ....: 444.08 MB Video Length .......: 01:14:41 Video Codec Name ...: XviD MPEG-4 codec Video Bitrate ......: 707 KB/s Resolution .........: 512 x 288 Aspect Ratio .......: 1.77:1 Framerate ..........: 25 FPS Quality Factor .....: 0.191 B/px Audio Codec Name ...: MPEG-1 Layer 3 (MP3) Audio Bitrate ......: 123 KB/s (VBR) Channels ...........: 2 Ch Sampling Rate ......: 48000 Hz

That looks good. Any zone settings? Could you post the quantizers from the statistic window?

The codec is "saturated" aka the compressibility is too high. Use no B-Vops (Max consecutive BVOPs=0) or use a high bitrate matrix.

I'm going to try encoding something else from satellite so I'll try 0 B-Vops on that. This is my source: elchup, you've made several rips from satellite recordings - can you give me a rough idea of what settings you use and by what process you end up with an XviD AVI? I presume you're starting with the recording as a TS file like me.

Satellite recordings tend to have less details, but every movie is different! And you should use a higher bitrate matrix rather than disable B-VOPs.

I suggest that too. Using a higher bitrate matrix enables you to get more detail and probably the file size you wanted. If you disable BVOPs you may also get the same fil esize but what you are doing is disabling the compression algorithms of XviD. That is like compressing files with WinZip and telling WinZip to compress only at an efficiency of 50%. Which doesn't really make sense imho.

I have no idea what a TS file is. I used to capture the audio/video with a capture card and using a lossless codec (HuffYUV) resulting in an AVI file. Then I open the AVI file with AviSynth using AviSource(...) and can apply all the filters necessary.

Well it worked! The filesize was spot on and the quality better than I expected.

I'll try a matrix when I re-rip my first attempt then, but not for this one since I'm satisfied with the quality. If the movie is about 90 mins and from TV and I'm aiming for 745 MB, what high bitrate matrix would you recommend? I'm not really into doing multiple attempts at a rip and my experience of matrices is that the end filesize can be unpredictable because of this. elchupacabra wrote: | I have no idea what a TS file is.

Ah I see, I presumed you were dealing with files imported from a PVR, which is what I'm doing. Thanks for your suggestions, and elguaxo too.

I can't remember the matrix, sorry. It must have been one of these: - EQM V3LR
- Jawor's ZSM
- EQM V3HR
I guess you don't want to wait hours encoding with a "wrong" matrix. You should run a compression test with several matrices OR use a pre-rendering pass (see here: viewtopic.php?p=204941#p204941). I would recommend the pre-rendering pass when using slow filters (which the cast almost every time for me).
