I have 2 times the same video
File2Code:Name: file.mp4 Framerate: constant 29.970 Duration: 00:23:29 Language: eng
Now i want to change the framerate of file2 so the framerate and duration are the same as file1 so i can add the audio track of file 2 to file 1. I have try many programs like handbrake and avidemux but without luck.Code:Name: file.m4v FrameRate: 25 Duration: 00:23:36 Language: dutch
Can someone give me a good tutorial?

The chances are that video 2 was created from video 1 and used frame-blending or other means to leave the run time as near as to video 1 as possible. But they really should be the same.
Now you can use avidemux to re-sample the frame-rate of video 2 back to 29.97 without altering the run time. Yet the chances are you could still not sync up the audio to the video.
Equally you could re-sample video 1 to 25 fps without altering the run time. But the same conditions apply for the 7 seconds difference.
Never thought sarcasm was in your vocabulary.
clever FFmpeg-GUI. Load file 2, select audio modify, in "Change Audio Lenght" insert 25 as source fps and 29.97 as target fps, set "Lenght and pitch", set as output ac3 or aac (your choice) and convert the audio. Then in the multiplex section load video 1 as video and the new created audio as audio and mux them.
Control sync with VLC Player and eventually remux with the right audio delay.
This would only make sense if the original frame rate of file 1 was 24fps. Then you could IVTC or decimate to 24fps and then speed up to 25fps. The length doesn't match, but this might have nothing to do with video speed and only reflect some minor difference in the video.
