I am a freelance computer programmer and system administrator hanging out in several Linux User Groups in and near Berlin, mostly LinuxWorks! and Nerd-Cafe. My jobs involve working for the Free Software Foundation Europe and for several places involved with the education of children.

On the side I have been involved in short movie projects and I am coauthoring a german language video podcast about GNU/Linux and Free Software. Watch the podcast on http://gnufunzt.de.

On stackexchange I have been most active on askubuntu.com, though I am really a Debian user and a stick-in-the-mud proponent of old-school Unix philosphy.

I started programming at a rather young age, and I am a strong advocate for Free Software.

comment Does mjpeg handle interlaced video correctly?
If you are archiving video for historical reasons, I'd recommend you use the FFV1 codec from the ffmpeg suite, which is Free Software. FFV1 is lossless therefore artifacts in interlacing is not an issue. Its output files are a little bigger than with mjpeg, though I have seen smaller results as well, depending on video material. Also there are different understandings of the mjpeg format by different vendors, FFV1 is clearly specified and since the source code is available, it can be ported to future computer platforms. Public archives in Austria, Canada and Australia are already using FFV1.

comment Does mjpeg handle interlaced video correctly?
To refine your question: proper handling would be if the JPEG artifacts remain within an interlace field, but do not span over the interlace lines, right? Because this would be all there is to it when handling interlacing. The video codec has nothing else to do with it.

comment Sync audio and video, equipment?
Oh, and don't feel bad if you didn't now. They never tell you this in the documentaries. I didn't find this out either, until I started hanging out with film crews.
