Trying to encode a clip to XviD to join another using VirtualDub ...

Hey everyone,

I have an XviD file with these attributes:

What I want to do is encode a separate file from MPG to XviD that matches these attributes so I can join them together.

I set VirtualDub to the same resolution, framerate, and data rate. But no matter how I tweak the data rate, it always comes out slightly different than the file I want to join it to. So the program won't let me join the files.

I tweaked it to the single kilobit a second, to the point where adjusting it 1 more still makes it way off. For example I set it to 1125 kbps and the resulting file has 1071 kbps, but if I set it to 1124 kbps, it comes out as 1064kbps!

Does anyone know how I can get it to give me a file with the correct data rate (1068kbps)? I want to avoid re-encoding the file I'm joining it to, to maintain it's quality.

Thanks

[manono]

It's not because of the video bitrate that they won't join. It's something else. What error message does VDub give you exactly? And is the audio also the same as originally? Same kind and bitrate?

[Phat J]

The error I get is:

"Cannot append segment (video.avi) The video steams have different data formats"

And yes I have matched the audio format on both clips.

Post the mediainfo for the other half

The second one has packed bitstream while the first one doesn't. I don't know enough about it to know if that can stop them from being joined. But the first thing I would try is to turn off packed bitstream when creating the second one.

[Phat J]

I tried turning off packed bitstream, same error message. I went as far as installing the same XviD writing library that was used on the other clip, and managed to finally match the data rate at 1068kbps, but it still won't join!

Here's the mediainfo from my latest attempt:

Maybe it's time to switch to AVIDemux which can be much more forgiving when joining AVI files than is VDub. Maybe someone else has a suggestion for VDub, but I don't know why they won't join.

[Phat J]

I'll try that, thanks for your help

I am having the same issue and I am ready to start stabbing people. I have captured video i would rather not recompress bbecause it is very nice. I want to encode and intro and outro clip to append to beginning and end. I have set everythign to match the framerate, fourcc, audio sample rate, and audio bits precision. Here is my media infos if anyone can help me. The first one is the into I made and can reencode, the second is the file I don't want to modify.

The frame rates are probably different. Use AviFrate to change one or both of them. The frame rate in an AVI file is indicated by two integers, a numerator and a denominator. If, for example, one of the files has a frame rate of 29970/1000 and the other has 30000/1001 VirtualDub will not append them, even though it will report both as 29.97 fps.

[duhmez]

OK I checked avifrate both have scale 1001 and rate 30000. If anyone has the ambition to check them. I could send over these files in dropbox for anyone to check out. These videos are my copyright so there is no issue with distributing.

[duhmez]

OK I will link the 2 files below if anyone is ambitious and can help me join these. Understand that I dont mind reencoding the intro file it is just the main file I don't wnt to touch, if anyone can tell me how to make it hapen I will be ever so happy. For the record I am not a noob either so any suggestions won't be folowed by dumb questions. The files linked below!

AviDemux was able to join the two clips and save without reencoding.

[duhmez]

AviDemux was able to join the two clips and save without reencoding.

Hey thanks for testing. In my case that worked too but it totally scrambled the audio int he second clip, totally ruined it. Did the audio work for u?

I mean TOTALLY screwed the audio. If it worked for u maybe i NEED to update my avidemux?

[jagabo]

I tried the full video in a couple players and it the audio was ok. MPCHC and VLC. I used AviDemux version 2.6.0 r7809.

[duhmez]

Thanls for 4tsting it, I wil update my avidemux nd give it another go.

[duhmez]

Hi again. I went to avidemux developer site, the highest version they have is 2.5.6 same as the one I am currently using. Where did u get 2.6?

[manono]

Probably a beta version available here:

http://avidemux.razorbyte.com.au/

[duhmez]

OK so I rebooted the pc, and now it joined successfully, but another issue, HUGE Macroblocks all over the place, ruined the video. Something is very wrong here. Using copy mode too and totally messed up video.

[jagabo]

Try opening the joined video in VirtualDub and saving again in Direct Stream Copy mode. Ie, remux the full video with VirtualDub.

[duhmez]

II tried it again with avidemux and let it unpack the bitstream, and saved as "avi, unpack vop" and it WORKED!!! Did not need to restream with avisynth.

When i tried to restream the broken avi in avisynth, it broke it more ^^ I did just for curiosity sake.

Thanks for all you help guys! Solving this issue will save me thousands of hours of production time, and ensure the highest quality videos for myyoutube channel.
