As crumja said, use VirtualDub
Follow this guide: 1-Open VirtualDub (DUH) 2- open the mpg file 3- go to the "video" tab and make sure "Full processing mode" is chosen 4- again, in the "video" tab , click on "Compression" 5- When the new window shows up, choose the 3rd one from the list: DIVX pro 5.0.5 Codec and then press OK 6- go to "audio" tab and check the "Full processing mode" 7- again in the "audio" tab, click on "Compression", when the new windows shows up, choose -> MPEG Layer-3 8- after you choose MPEG Layer-3, a new list will shows up on the right. Choose the 3rd one and press OK 9- go again into "audio" tab and click on "Conversion", under Sampling Rate, check on 22050Hz , also check on "High Quality" and then press OK 10- go under "File" and choose "Save as AVI" or simply press F7 11- choose where u want to save it and then it should convert it. |

5 - It won't be the third one on everybody's list, and most people won't even have it installed. Besides, xvid is a better choice both quality and performance wise 6-8 - Virtualdub audio processing sucks 9 - 22050Hz? Are you out of your mind? I recommend you go to Doom9 and read some of the guides they have, those should give you some idea on what to do. As for the settings, well... Download AviSynth Download VirtualDubMod Download BeSweet (only if you want to re-encode the audio) Get some filters from here: http://www.avisynth.org/warpenterprises/ Namely Fluxsmooth and Mpeg2dec3 (fixed) Sharptools (SSXSharpen()) can be found here The required DLLs (aWarpSharp, Warpsharp and Masktools) for Sharptools are up over here: http://mf.creations.nl/avs/ Open up notepad or some other text editor and type something like this in it: Loadplugin("C:\Progra~1\AviSynth\plugins\aWarpShar p.dll") Loadplugin("C:\Progra~1\AviSynth\plugins\MaskTools .dll") Loadplugin("C:\Progra~1\AviSynth\plugins\WarpSharp .dll") Loadplugin("C:\Progra~1\AviSynth\plugins\FluxSmoot h.dll") Loadplugin("C:\Progra~1\AviSynth\plugins\MPEG2Dec3 .dll") Import("C:\Progra~1\AviSynth\plugins\SharpTools-v0.3.avs") MPEG2Source("your file here") FluxSmooth() SSXSharpen() And save the file as an .avs. Naturally you should change the paths to match your system. Using the filters in AviSynth give rather nice results in my opinion, but SSXSharpen() is a bit slow so you might want to use something else if you don't want to spend too much time encoding. Msharpen should be ok I guess, only used it a few times so I don't have much experience with it. You won't need Sharptools, aWarpSharp, Masktools or WarpSharp if you use it so it's a lot simpler. EDIT: Another choice would be aWarpSharp by itself After you think you've got everything right, try to open the avs file in a media player. This will let you debug the file, when there's something wrong with the .avs it should print out an error message as a "video". If everything is correct, the video will actually start playing (slowly). After the avs is okay, open it in VirtualDub. Go to video, select fast recompression, go to compression, select xvid. Pick either single pass or two pass - 1st pass. Two pass encoding is preferred but again it's a question of how much time you're willing to spend encoding, two-pass encoding is roughly two times slower than single pass . Decent settings would be (I'm assuming you have the newest xvid codec): For single pass only: set the bitrate to less than half of what it is in the mpeg (to leave space for the audio) For two-pass - 2nd pass (you'll need to have a stats file from the first pass for the 2nd pass): Set the file size to slightly less than half of the mpeg (for the same reason) Profile Tab: Profile level: Unrestricted Quantization type: H.263 (for better compression and slightly better speed) or MPEG (slightly sharper) BVOPs: yes Max consecutive bvops: 2 Quantizier ratio: 1.50 Quantizier offset: 0 (well, I do it like this anyway, not really sure if it's the *best* way to do it) Packed bitstream: NO Closed GOV: yes Zone options Chroma optimizer: yes Advanced Options Use Chroma Motion: yes VHQ mode: 4 (or 1 if you want speed, doesn't have that much of an effect) Motion search precision: 6 Maximum i-frame interval: 300 Use cartoon mode: yes Turbo: yes / no - I can't really see a speed difference while using it but maybe it works with other people Trellis quantization: yes In audio, set audio to "no audio". It's easier to mess around with audio in VdubMod For 2-pass, you'll have to do two encodes. First one with twopass - 1st pass and then another one which will actually result in a file that works (well, you could turn off the dummy 1st pass option if you want a working file from the first pass too but I don't really think it's that useful). For the audio: Open the original mpeg file in vdubmod. Select the audio track you want to keep and select save as wav. EDIT: Use besweet to re-encode the audio if it's too large (ie if it's really a PCM wav file, virtualdubmod will save the audio track as a *.wav file no matter what it might really be), it's quite easy to use with the GUI. Then open your encode, go to stream list, click add, add the audio track you extracted from the original file. Go to the video tab and select direct stream copy. Save the file. Naturally this won't result in a great file in all cases but it should give a decent file anyway Whew, that was a lot of text Last edited by Cruzz; 2004-01-25 at 10:25. |

A quick look at the documentation would suggest that this command (besplit is a command line application like besweet) might work: BeSplit -core( -input thethingvdubspitsout.wav -prefix c:\channel -type wav -demux ) This should split the file into seperate channel files named channel0x.wav and place them in C:\ Last edited by Cruzz; 2004-01-25 at 14:28. |
