Joining 2 divx files with very close, but diff framerate

[jorwex]

aight, so i started capturing an episode of something with my AIW radeon 32 ddr with MMC. after about 15 mins it started dropping frames like crazy..

so i decided to finish it off using virtualdub.

that got the rest of it. i think it dropped a frame or two.

so i converted both to divx 5 @ 1024 kb/s and mp3 audio @ 128 kbps

now i wanna join both halves..
but vdub gives me an error concerning their differing frame rates..they're really close..like within a few 10ths of a fps so i figured i'd make them both exactly the same thing with vdub. i didnt think that small of a difference would yeild an a/v synch prob, but it did..a noticeable one.

when i fixed them both tho, i tried joining them anyway, and vdub still wouldnt do it, saying the sampling rates were different..
those were also very close.

i tried a buncha diff. conversions..stil nuttin..

ANY help would be greatly appreciated! im sick of these two files on my desktop..THEYRE MOCKING ME!

Hello

Well you could change the FRAMERATE of one or both to match each other. This might throw the audio ever-so-slightly out-of-synch though. But I have seen DivX files with "off" frame rates (like 23.970fps when it really should be 23.976fps etc.) so if the current framerates are VERY close as you say then any loss of audio sync might not be noticeable.

When doing the frame rate change in VirtualDub set video AND audio to "direct stream copy". Change the frame rate (it is under the VIDEO drop down list) then save "Save as AVI ..." (F7) to a new file. This proceedure will NOT re-encode the file ... just create a new file with the framerate that you indicate.

BOY do I feel stupid. After I typed all this crap in (hehehe) I re-read your post and realize that you tried this already. DUH! Sorry I think I'm just tired ... time for bed

I saw this in aprevious post (but havent tried it yet) http://home.planet.nl/~doesw008/filemerger.html
Try searching all forums above for Filemerger and you will find the original post.

hey, FulciLives

ya i said i changed the framerates with virtualdub and it DID actually ahve a noticeable a/v synch problem. so i already did what you said.

ill check out that other thread, Atmos

Atmos, sorry i thought taht was a link to another thread at first glance..

so i tried the tool, and it took a minute or so to merge, and it spit out a file.

Each of the two original files were about 5-6 mins each, and the file it gave me was only 2 minutes...hrmm

BUT if u add the filesizes of the two files its about 87 megs..and thats the size of the other one...

puzzled i am....

EDIT!

i take it back..the new file is exactly the same timelength as the first file.

Sounds like the tool you used to join them is at fault. If they are close to each other, the easiest method is to join them via AVISynth: http://sourceforge.net/project/showfiles.php?group_id=57023

This method will keep your audio in sync. Create the following in Notepad, and save it as a .AVS file (example: video1.avs )

AVISource("c:\my folder\my avi.avi")
AssumeFPS(29.97, True)

Of course you need to correct the path of the AVISource command above to point to your AVI file. Save the file (with a .AVS extension). Lets call it video1.avs for this example. Create a copy of video1.avs, and call it video2.avs. Again, correct the path to the AVI file on the AVISource line but this time, set it to the path of your second avi. Save it and close notepad.

Open the first AVS file (video1.avs) in VirtualDub. Set AUDIO to "Direct Stream Copy". Set the VIDEO menu to "Direct Stream Copy". From the file menu, select FILE | APPEND AVI SEGMENT. When prompted, select the second AVS file (video2.avs).

That's it. You then select FILE | SAVE AVI, and give it a new filename.
