I would like to combine multiple movie clips with .mov and .avi extension into a single file. Is there any free software in the market that is good and able to perform that?

Preferably that should work without any loss in quality.

  • are you looking for simple concatenation (joining end-to-end), or are you looking for something more complicated (non-linear editing)? Dec 12 '09 at 3:08

I use Avidemux for tasks like this.

enter image description here

Process with Avidemux is as follows:

  1. Choose File->Open and select the first file
  2. Choose File->Append and select the next file. Repeat this step until all the files you want to append to the first file have been appended.

  3. Choose Save and select location and filename

    Would appreciate if you can provide the procedure for performing such operations in avidemux.

Try mencoder or ffmpeg, both free, both good.

Mencoder

mencoder -oac copy -ovc copy -o output.avi input1.avi input2.avi

FFmpeg

From the FFmpeg Wiki article on how to concatenate (join, merge) media files:

Create a file "mylist.txt" with all the files you want to have concatenated in the following form ( Lines starting with a dash are ignored ) :

# this is a comment
file '/path/to/file1'
file '/path/to/file2'
file '/path/to/file3'

Note that these can be either relative or absolute paths. Then you can encode your files with:

ffmpeg -f concat -i mylist.txt -c copy output

    if you're joining multiple files of different codecs, yes, loss of quality is likely -- the tool will need to re-encode the streams so the final stream uses the same codec/bitrate throughout. Dec 12 '09 at 17:22

    Best answer, too few upvotes and not accepted. Shame ... +1 from me. Mar 1 '13 at 1:28

You can add an unlimited number of video files as you like to the list and easily rearrange their order if needed. With just a few mouse clicks, you can enjoy your movie clips without interruption.

Use any video editing software (even Windows Movie Maker), import the files into the Editor timeline, then export it as a new movie. If you can pay - "Camtasia Studio 8" is the best choice as it takes less ram and CPU to produce HQ output files.
