Avidemux format problem

[doodi4]

Hello!

I created an intro animation to a youtube user.
He recording bike trips whit his camcorder and he uses Avidemux for editing.
He don't want to change his workflow, but when he try to join the videos the
program makes it messed up. So i decided to convert cobranco.mp4 to same as pict0230.mp4 .
I tried on various apps like premier pro, AE.
But the problem in avidemux remains. I uploaded the files i hope you can help me.

These 2 files have same codecs and framerate, but different resolutions. Avidemux can not join 2 videos which have different resolutions. So you have to convert the intro to resolution 1280x720 before trying to join them in Avidemux. Try this and post again if it helps.

I updatet the intro link to the changed 1280x720 res video. Now i can drop it to the program, but after the joining. The result is: the intro is good but the another video got black screen with no sound. But I can see the time is increased. So it looks like its joined, but with this error.
