who decompresses an avi

[matneaves]

ive not been on the forum for some time, and thought id just pop in and see whats the latest, and ive noticed same old questions and problems with converting avi's

ive read replies that only confuse the matter when its really a simple problem

posts saying that winavi is rubbish and has synch errors.....little tip..decompress avi 1st, end of problem, its that simple, i get superb results, and so do my friends cos the do the same way as me

but what i dont see and it amazes me is why people dont decompress avi BEFORE trying to convert

am i the only one that has NEVER had a sync or other problem in converting because i decompress them 1st

question: does anyone else decompress their avis?

What do you mean by decompress avis? converting to uncompressed avi or ?

Most sync problems are because of vbr mp3 audio and it will often help to convert it to wav.

[mats.hogberg]

No, as I've got hardware that supports AVI playback. The player set me back about the same sum as most commercial AVI to DVD offerings, and of course saves lots of work and time.

what i meant was, say an avi was about 718 megs, when i decompress it, it creates a new file say eg film/clip_pcm.avi, which is about 1 gig+, then convert that avi to dvd s/vcd, ive read people trying to to convert the original 718 meg divx/xvid avi and get synch probs

other day my m8 was trying to convert a avi, and said it kept on crashing his converter prog, i said decompress it 1st he did that and converted no problem

this is the prog i use



"Most sync problems are because of vbr mp3 audio and it will often help to convert it to wav. "

yep thats what the decompressing prog does, but keeps it in avi format, no need to seperate the wav

[Baldrick]

I still don't understand what you are doing. What tool are you using to "decompress"?

[Baldrick]

I see. But some tools handles vbr mp3 well like ConvertxtoDVD and DVD Flick.

i was wondering if anyone else uses the decompress prog
just re read your article about using tmpegenc with the movie.avi and movie.wav, i used to do that method, it was helpful n1

If AVI Audio Decompressor can handle the audio, then there is no reason (other than it being crap) why WinAVI can't.

dont make sense

[guns1inger]

What celtic-druid is saying is that is one program can correctly decompress a type of audio, then there is no reason any other software cannot, unless it is rubbish. WinAVI cannot decompress this type of audio correctly, ergo it is rubbish. (Actually, WinAVI is rubbish for so many more reasons that just this)

[celtic_druid]

Exactly. TMPGEnc always had problems with VBR audio to (this is probably the main reason why AVI Audio Decompressor exists). It did however have other redeeming qualities.

Also worth considering for apps that can't handle audio is to use AVISynth to frameserve. That way the audio gets decoded by AVISynth on the fly.

[matneaves]

fair enough, thats prob why i learnt ages ago to decompress 1st , before the new progs that can handle it came out, going back about 4 years now , prob thats why
