2 cd divx to 3 cd svcd?

[mb571]

Hi folks. I have a 2-cd, divx movie, 130 minutes long. I would like to make a 3-cd, SVCD conversion, each cd being around 43 min. I am not too sure how to go about it. I used TMPGEnc to cut up the avi's as follows:
CD1 44 min
21 min
CD2 21 min
44 min

I tried to join the two 21 min mpeg2 files with TMPGEnc, but the audio was so far out of synch it was unwatchable. Could you join the two divx avi files somehow and then split it up into three nice chunks with tmpgenc?

I'm not sure if you know this but you will not gain any quality from converting your vcd to svcd. In fact people say it may actually get worse.

However if you have the original file and it has a real good bitrate you could make either a svcd or xvcd

Hope this helps

Get Virtual Dub and open one file, then Append the second avi file. now you can cut it into the sections u want. dont forget to mark the 'direct stream copy' on the video and the audio

Who said anything about vcd to svcd. I am going from divx to svcd.

I have virtual dudand will fiddle with it tonight. Can you explain a bit more about mark the direct stream copy.

Thanks, Mark

Sorry I mis-understood what you were saying
When I read 2 cd I thought that you were talking about a vcd.
I've never hear of anyone asking about a 2cd divx.

Also I think you should ceck the bitrate of the original file becaus think if it's already cut in 2 then it may only be vcd quality

Now if you are going to follow gravitys advice.
Here is what you do
Open video file then click append video file, then add second file. Now under video click on direct stream copy and under audio click direct stream copy , when finished you will have a movie which is one big file the split it up in three

Talk to you soon

Well vd won't let me add (or append) the second avi file. It says
"Cannot append segment: the audio streams have different sampling rates"

So why do you post in the dvd ripping forum?

Well vd won't let me add (or append) the second avi file. It says
"Cannot append segment: the audio streams have different sampling rates"

Well, that's a pretty verbose error message. Extract the audio files and downsample both to 44.1 kHz.

[mb571]

I put it here because every other forum says no divx to, and this one says:
"Everything about DVD ripping, decoding, conversion and encoding from DVD to MPEG VCD, SVCD, DVDR or DivX using Smartripper, DVD2AVI, ifoEdit, DVDx, TMPGEnc..."

Respectfully, Verbose means: "using more words than are needed"
I would say the error message is precise and to the point. What did you mean by verbose?

After you have extracted the audio files, how are the avi's to be joined then with virtual dub? When you try to add the second video file it will still give you the error message.

Newbie Conversion
Conversion from downloaded videoclips such as AVI,DivX,ASF,MOV,RM to MPEG VCD or MPEG2 SVCD,DVD. So this forum is OK.

Well, everybody here knows, that my english is quite poor. Of course I have meant "precise".

If you want to append a 2nd segment, it must have the same specs as the 1st one. Since there was no video error message, you have to correct the audio only. I recommend to extract the audio with VD, open the avi, select file > save wav. Downsample with an audio editor or VD. After that there are several ways. Remultiplex to the avi with VD. Or you can frameserve the video files only to TMPG and load the audio (after merging with an audio editor) into TMPG directly, as you like.

In TMPGEnc use the source range filter to split the output file. Add as file1.mpg and file2.mpg to the batch encode list. As long as you use CBR or 2passVBR, you can calculate the filesize exactly to fill the SVCD to its edge if you like.

Can I recommend an easier way to join two avi's using Virtual Dub thats always worked for me, but only if u dont mind a massive file after words.

Open the first half and set video to direct stream and audio to full processing, leave all the settings in the conversion tab to no change, then click on compression and click on No Compression PCM, then save the avi.

Do this with the second half and the two will join together flawlessly, if u cut it right, the only problem is u need a lot of hard drive space to do this, even though i delete most of them afterwards, you could try compressing the sound to a constant rate mp3, but i havn't tried that yet so i can say too much about it.

Hope that helps, it works best for me and also helps Video/Audio synch as well.

Well I gave it a whirl. I saved the two avi's running them through vd with the above settings and both files are perfect. But when I joined them, the audio sync is out as far as lightning and thunder at 20 miles.

I had that problem the other day with Ali which is 2 disc Divx and i wanted it on 3 CDs, cause of the length.

I joined the two Avis and uncompressed the audio but if i skipped forward using power dvd or windvd then the audio was out of sync, but when i cut them into 3 files and watched all 3 files the sound was fine. ive since burned the 3 discs and watched them and its perfect.

I dont know why it goes out of sync sometimes and why recutting them fixes it, but its worked twice for me now, is there anyone who knows why could they please let me know as im always trying to learn more.

Hope this works for you, let me know.

[mb571]

Very good pal. Thanks for your help. As you said, after splitting it up to 3 svcd's it works fine. I was skimming the joined avi in Win Media Player to check it and like you found, the audio was way out.
I would like someone to give a technical brief on the difference in direct stream and full processing in virtual dub.

Just Thought I'd Add something i just found out about Virtual Dub and Audio synchronization.

On Oceans Eleven there were a few frames i couldn't encode, well not through CCE, Tmpeg could do it, but i dont use that anymore, as it takes too long, and i like to use at least 3 pass VBR.

I cut out the bad frames and joined it all together but found the sound to be badly out of sync yet again.

But for some reason i encoded it anyway on a quick CBR using CCE, it was only 55mins and took just 35 so i wasn't bothered.

Strangely though the finished MPEG is fine, even if i load the original AVI and the converted MPEG into Power DVD, the audio is off on the original and fine on the MPEG, i dont know if this turns out the same using TMPEG but using CCE through DVD2SVCD it does.

Does Anyone have an explanation for this

[gizmo20]

i just run the old cmd does prompt then type COPY /B FILE1.avi+FILE2.avi FINISHED.avi

Then do the file chopping from the one big file

media player has known audia/video sync issues. use winddvd or powerdvd to verify audio sync. ALso use daemon tools to preview the .bin image before burning to avoid making coasters.
