But those are command line tools. PITA when you cannot > work off of timelines.. I tried ffmpeg *almost* successfully. I'll explain what I want to do: add a simple text presentation to a mymovie.mpg video file. That's what I did: in Cinelerra I loaded a file image.jpg, added a silent audio track and converted all that into two files: image.wav and image.m2v. Then I did: $ ffmpeg -i image.wav -i image.m2v -target dvd -acodec pcm_s16be -b 8000k -s 720x576 -ab 1536k -ac 2 -r 25 image.mpg so obtainig the file image.mpg. Then I did: $ cat image.mpg mymovie.mpg > total-movie.mpg and... they were properly joined together except for the fact the *sometimes* yes and sometimes no, a noise is heard when playing total-movie.mpg back with Mplayer, just as soon the second file begins. The noise immediately stops hitting an arrow key on the keyboard. > Otherwise, you can splice videos together with offsets etc.. worked quite > well for me. .. and do format conversions quite easily. What do you mean by offsets? Thanks Rodolfo -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
