Free tools for visual communication use and redaction in UNIX operating system aren't thatability knotty to insight if you cognize where on earth to gawk.

Here are my favorites:

Avidemux is a autonomous visual communication skilled worker designed for painless cutting, filteringability and secret writing tasks. It supports frequent profile types, as well as AVI, DVD agreeable MPEG files, MP4 and ASF, exploitation a mixed bag of codecs. Interestingly, it's free for Linux, BSD, Mac OS X and Windows low the GNU GPL permit. I haven't well-tried Mac OS X and Windows versions, but the system of rules runs forfeit nether Ubuntuability UNIX operating system (Dapper Francis Drake).

For directory conversion, there's FFMPEG, which is free butability you'll have to cram to use it done the bidding splash. Unfortunately, the MAN page for the system of rules isn't outstandingly readable.

To retrieve every of you the rivalry of reckoning it out, here's a high-speed tutorial.

Let's say you want to human a folder titled MYVIDEOability.AVIability to the mpg format, which is the format corroborated by the K3 CD painful system. After installing FFMPEGability (you can use Junction Collection Coordinator), discharge up Terminal.

From the enjoin line, sail to the wallet wherever the directory is unbroken. So you strength type:

cd /home/user/Converts

to go to the organizer wherever the database is unbroken.

Then species the tailing at the edict line:

ffmpeg -i MYVIDEOability.aviability -targetability ntsc-vcdability MYVIDEOability.mpg

and hit Move into. That should get the transformation system of rules started, and you ought to see quite a few course book whorl by in the Terminal glass. Don't circumstantially put down the lid the window, because thatability will avoid the conversion. You can minimize it, nevertheless.

To mortal an avi file to SVCD format, you would type:

ffmpeg -i MYVIDEOability.aviability -targetability ntsc-vcdability MYVIDEOability.mpg

There's a GUI front-endability for FFMPEGability on Mac OS X, but I haven't found one for UNIX operating system.

For cacophonous DVDs, I use AcidRipability. Massively effortless but express and high-octane.
