Many times when I download videos from youtube though Youtube Downloader or Free YouTube Download these are in parts ending with name like part 1 or 1/2. I searched on the internet how to join these. I came up with a program Avidemux open source program available for multi platforms. It can join any video files in seconds. Because it does not recode all the video unlike other video editing programs.
This program can be used for cutting, filtering and encoding tasks. It supports many file types, including AVI, DVD compatible MPEG files, MP4 and ASF, using a variety of codecs. Tasks can be automated using projects, job queue and powerful scripting capabilities
To join two or more files.
To join two videos, they must have same resolution otherwise they will not join without cropping
Simply drag or open any video file. If you see any warning for safe mode click no. If you see any warning for Index click yes. You will see the video has been opened Now in the File Menu click Append. Select the other file. Open it you will now get the mixed video on the interface. If you want to join more files then again Append them.
In the Format select FLV or MP4 depending on the source video format. Click Save and type the name of the new file with its format (otherwise you will have to manually give the format from explorer.)
You are done.
