Just discovered taht the videos taken with Kalle's super camera are in PAL, so created a corresponding compress_pal.sh and I'm runnning the Nokubi video through that, and the other two through compress_ntsc.sh All good and under control -- but hte video recompression had to be restarted.copied to /usr/local/bin on videorain
For NTSC captures _please_ change the -s option! It assumes PAL. Use -s 320x240 instead of 384x288. I repeat: PAL: 384x288 NTSC: 320x240 The reason this is so important is that most of the cameras output interlaced video, and I don't use a deinterlacer. I just halve the number of lines exactly. If the downscaling does _not_ exactly halve or 1/4 the number of lines, there will be ugly interlacing artifacts! Why not deinterlace? It's faster and less lossy if you can avoid it. -- Herman Robak -- To unsubscribe, send mail to debconf5-video-unsubscribe@lists.debconf.org.
