[Rock-dev] Avi export for log files

[Steffen Planthaber]

Hi,

After you got the export of several frames, from rock-export giving i.e.
--start 0 --end 100, you can use ffmpeg to put them together in any
format. ffmpeg (mplayer) supports it by using the "image2" format as
input for ffmpeg:

$> ffmpeg -f image2 image%02d.png out.mpg

puts together all images with a two digit number image01.png, image02.png

You'll need leading zeros for a correct order in the video.
I don't knot the output filename of  rock-export, but the "%02d" is for
two digit numbers, %03d for three.

For bitrates, resolution and stuff see the ffmpeg manual.

Best,
Steffen
