joining serveral files with mp4box results in 2 video-streams

[Obc]

Hi...

First: I searched this forum and i googled a lot but didn't find an answer for my problem. Perhaps anybody could help me here?

I tried to join five mp4-files (same codec, same resolution, etc.) with mp4-box. I used the recent release 0.4.5 and the 0.4.6 beta.
I tried to join the files with the command mp4box -cat 1.mp4 -cat 2.mp4 ... -cat 5.mp4 output.mp4
While processing mp4box spits out, that no suitable destination track was found. but it does this twice, so the output-file hast 1 great videostream and one small which both play at the same time as i try to play the file.
here is what mp4box says while joining these files:

D:\>mp4box -cat 4-1.mp4 -cat 4-2.mp4 -cat 4-3.mp4 -cat 4-4.mp4 -cat 4-5.mp4 output.mp4
Appending file 4-1.mp4
No suitable destination track found - creating new one (type soun)
No suitable destination track found - creating new one (type vide)
Appending file 4-2.mp4
No suitable destination track found - creating new one (type vide)
Appending file 4-3.mp4
Appending file 4-4.mp4
Appending file 4-5.mp4
Saving to output.mp4: 0.500 secs Interleaving

When I play the output.mp4 e.g. in vlc-player two windows are opening themselves and start a different playback.

Here is what mediainfo spit out:

Now my question:
How can i join these 5 files with having _one_ videostream in the end?
By the way: I tried these commands (mp4box -cat 1.mp4...) with other files and there it worked

Greetings and thx for your help,

Obc

If you use a mp4box gui like yamb do you get similar result?

I have not tried joined using mp4box yet so I'm not sure how it works.

[Obc]

Yes, sorry... Didn't mention this in my first post.

I tried it then with Yamb... Same Problem. I got two videostreams :/

[poisondeathray]

mp4box -add 1.mp4#1:fps=23.976 -cat 1.mp4#2 -cat 2.mp4#1:fps=23.976 -cat 2.mp4#2 ..... -new output.mp4

You could also try appending with avidemux

Thank you for your suggestion but it doesn't work...

Again the two video tracks...

I'm gonna have a look at Avidemux...
