How To Join MP4 video files

[Aashik Alam]

how to add 3 video parts to a single video
I have downloaded 3 parts of movie from daily motion
and try to join with AviDemux. but the result is not fair.
it only join 2 parts of video and 3rd part video is not view but audio is present

say me about any other programme
that join all types of video without encoding
Also try yamb , mp4box , mkvmerge,

[Baldrick]

And all fails? Or create an unwatchable mp4 or mkv?

Has all mp4s same video properties? Check with mediainfo. Frame size/resolution, frame rate and video and audio codec.

The third part might be corrupt.

Thanks for replay

Yes , all videos has same properties
all video downloaded from dailymotion in 480p

I would guess the third part has some problems then. Try add it in mkvtoolnix and make a mkv. THen join with the rest.

Using the ffmpeg's concat on the same mp4 (AVC/AAC) to be sure the format were all the same worked for me. Do you by any chance have multiple audio tracks or subtitle tracks in these videos?

Aashik Alam... FFMpeg is a command program but not a GUI. The photo of the GUI above that uses FFMpeg is mine, called Media Utility or FLV Media Utility, depending on which version it is. It is a beta program I wrote that does most of the operations that people request here on an ongoing basis. Using it, I do not have to look up the scripts or formatting (My memory is only so good these days, LOL).

I use it to verify something works using FFMpeg and/or AVISynth before posting a reply and then I include the image to show exactly what was done and the scripts used. Above shows the 3 files to be joined, the ffmpeg script to join them using concat, and the actual filelist.txt created for its use.
