i have a good quality anime in hand, which is 640x480 23.976fps WMV9VCM
now i would have a modify on the image so i trimed a small clip from it, killed the audio and saved it to a new file
then i used avisynth and overlayed something on the image and opened the avs in vdm
exported it into avi using wmv9 codec, single pass qb95 and with fast processing in vdm(so it should remain YV12 colorspace)
when all things done, i tried to join them together. Ooops, the dialoguebox which you may have seen for so many times appears, say The video streams have different data formats.

you can see, both clips are
640x480 23.976 wmv9 no audio

and i tried for yv12/yuy2/rgb24 colorspace, and no one worked...

and then i have tried avimux, but i don't find any button or checkbox which says 'join', as well as in matroskamuxgui

now i have no idea, plz help me

best regards,

the bitmapheader is probably different...

you do not need a "join" button in AVIMux GUI... just add the clips in the right order and save.

well, i have tried this
the 2 avis are 36MB and 18MB
i added them to the avimuxgui, and 'generate data source from file', right?
then press the 'start' button, and only a 36MB file appeared!
if i click the 'source2' in the listbox, then only a 18MB file generated!

and then i have no idea...

well, they are joined successfully. but *only* the join is successfully.
however i do, the second part of the joined video is image-broken, hugh amount of MSK on the screen, obviously there's something wrong...
why......

one more:
the video was encoded by WMV9VCM, so which options could cause that i can't join them together

And thats probably why VirtualDub didnt want to join them ;)

Maybe WMV9 VCM stores some vital info in one of the avistreamheaders, which you will obviously lose for the second file. Just take one file, add that two times in AVIMux GUI and see if a join works fine then (after all, all characteristics must be the same then). Also try that in VirtualDub to rule out any errors in AMG.

I don't know what options you must keep the same for WMV9 VCM. Probably all except bit rate. But its not like there are millions of options to begin with in there...
