Virtualdub used with or without AviCutter=Sound Synch Problem

[johnharlin]

What should I do? I want to join 6 parts of a movie in avi format together that have a minute of credits flowing down at the end of each episode. I want to eliminate those credits. After I finish the cutting if I ever do, I want to convert them all to one DVD movie.

I have tried to use virtualdub with avi cutter and it certainly edits out the end of the movie but it leaves really bad sound synching - mouths speaking don't follow the sound.

Do I need to adjust something in the settings or should I just move on to another program that might not have sound synch problems like VideoReDo.

Try VirtualDubMod. Answer "no" when it asks if you want to rewrite the header (when you open a file). That might work.

Or try AVIDemux.

Thank you. I'll try it.

I do stuff like this in Avisynth.

s1=AVISource("sja-101.avi").EnsureVBRMP3Sync()
s2=AVISource("sja-102.avi").EnsureVBRMP3Sync()

s1.trim(0,39057) ++\
s2.trim(2138,39560) ++\
s2.trim(40594,0)

LanczosResize(720,576,0,0,640,352)

This is to join together a two-part story, cutting the "previously on" and "next week" bits so it runs continuously.
The EnsureVBRMP3Sync() does what it says. It makes it really slow if you're skipping around in the file in a player, but that's not a problem when encoding.

You can save the sound out from VDub, or use wavi, which extracts audio from AVS files.
Either method will give you WAVE audio (as Avisynth decodes it from whatever was in the AVI, usually MP3).
Then encode that to AC3 for DVD.

Or you could just load it in VDubMod and save out to a new AVI if that's what you want.

I use AvsP to edit the AVS script, but you can do it in VDubMod if you prefer.

The experimental version of Virtualdub 1.7.X_Test6 supportx VBR mp3 and in Smart Render mode, you can do exact frame editing.

This site is great for advice but what some people don't realise is that we're not all geeks when it comes to editing software. There are lots of programs that are recommended to do this and that but generally they are far too complicated and having searched the net for the relevant tutorial the finished edit is far less impressive than the research and the effort that went into putting it together. I've noticed that programs like VirtualDUB, Besweet, AVI2DVd and the rest are not really suited to my needs.

I have found the best way to keep audio and video in sync is not to demux it in the first place. For example, demux a video on DVD LAB and 8/10 times the audio will be longer than the video or vice versa. Similar results happen with the other oftwares too. TMPGEnc Xpress and DVD Author are probably the best editing software. You don't have to demux to edit and the results are generaly excellent. Nevertheless if you want to edit and keep your 5.1 surround sound then they are useless because then you have to demux (neither software supports 6 channel encoding although DVD author will cut a 5.1 movie and keep the audio but there are other issues) and thats when the sync problems start.

If you are like me and want to edit your home movies or one of your OWNED DVD movies then I would recommend either TMPGEnc for the 2 channel stereo stuff or ULEAD VideoStudio for the 6 channel stereo. You could use ADOBE Premiere Pro with the SURCODE surround sound plug-in if you have it but I'm not sure if Premiere will import VOB files. ULEAD 11 definitely will. The only drawback with ULEAD is the edit interface. It is not as good as TMPG but the end results are the same with the bonus that you can keep the 5.1 audio if you want and edit the whole thing in-situ with your video without having to demux. Furthermore I'm not a big fan of AVI as used in VirtulDub. My experience in the past is that it creates too big a file and if you try to compress it using one of the many codecs you lose some of the quality. The VP61 codec that my virtualdub uses produces an upside down movie!!!!

So my advice to you is to keep it simple. You can demux this, AVIsynth that everyting else but unless you are a complete geek these are beyond the comprehension of the average home editor. Don't get me wrong. They probably have a place somewhere, it's just that when I come to edit a video I don't want to have to trawl the internet for freeware and tutorials when all I want to do is cut out the parts of a movie that I don't want to keep. What could be simpler than turning a 60 minute movie into a 50 min movie. You should just be able to cut and burn...not have to go through a complete 6hr excercise of decode, recode, demux, remux, convert to AVI then convert to MPG then convert to DVD.

There......enough said.

The OP asked how to trim and join several AVI files (without reencoding), not how to reencode and make a DVD.

I'm sorry but is it because you are miles away from me that you have to give a smart arse answer. If we were sitting together in a pub I'm sure your response would be different, it would definitely contain less sarcasm. I was expressing my opinion and anyone can take from that whatever help it might provide. It may not answer the question but at least I provided a response. I don't believe you did.

Sarcasm?

<sarcasm>Are you blind?</sarcasm> I gave him two suggestions on how to do exactly what he asked for.

What are you on?
To the owner of this thread. I must apologise for ruining your thread. I tried to help but there appears to be some arsehead wishing to instigate some form of trade off for which i will not get embroiled. Suffice to say that if this guy/gal had one less braincell, the chair in which they are sitting on to type this rubbish would instead be sitting on them. I wish you luck in obtaing the answer to your question.

The OP mentioned "I have tried to use virtualdub with avi cutter" which shows he is above the vegetable level you have assumed. Avisynth is not hard. He can do what he wants with three lines of code, for free. He will take at least as much time to learn the ins and outs of any editor, free or vastly expensive. And at the end of the day, not get a better result in a shorter time. "Keep it simple", as you said.
