3 Technical Hints

3.1 Handling of individual 'takes'

My Canon HG21 will produce MPEG files with the ending MTS. These files can be concatenated very simply like text files. If you have a number of MTS files and want to concatenate them into one single file, you just do it with this command:

cat *MTS >> newmovie.MTS

The file newmovie.MTS can be processed just like one normal film.

3.2 Movies for DB0MHB

Videos recorded with my Canon HG21 camcorder need to be converted with the following command:

ffmpeg -i infile.MTS -s ega  outfile.mpg

3.3 Movies for Youtube

The following command converts MTS files from the camera into a Flash video format that can be uploaded to Youtube right away.

It is important to make sure that the videos do not exceed the length limit of currently 15 minutes. Experience shows that this is also somewhat the limit at which a movie starts to be boring.

ffmpeg -i infile.MTS -ab 56 -ar 22050 -s 480x272 -aspect 16:9 outfile.flv

The video can be uploaded to Youtube right away.
