Hi all,
Just switched to linux from os x and I'm trying to figure out my new video workflow. I've used dvgrab to capture my hv20's 24p stream. Now I want to strip out the extra frames (reverse telcine) and create a 24 fps image sequence of the video. Preferably tiff, but tga or png would work too. Is this possible with mplayer or ffmpeg maybe? any advice much appreciated. thanks, jayson

Hey kaz2100,
thanks for the link. I figured it out earlier today and forgot to post my solution:

alright looks like i figured it out. It's not perfect but for now it works.
so i have a canon hv20.
I captured the 24p hdv off the camera via firewire and dvgrab
then I typed all this into the command line in a directory that I want the png images to be written into:

mplayer /mnt/cycle/grab/test.m2t -aspect 16:9 -mc 0 -fps 30000/1001 -delay -0.222 -ao null -vf pullup,softskip,scale=768:576 -vo png

notice I reduced the image from HD 1440:1080 (4mb per png) to Pal 768:576(1.3mb per png), because I like working with smaller files and mostly just make web video anyway so I don't need the extra HD rez. But if you want to keep it HD replace 768:576 with 1440:1080.

there's probably a cleaner way to do this since the commandline reports all kinds of errors:

For AVI files, try to force non-interleaved mode with the -ni option.
Cannot sync MAD frame
TS_PARSE: COULDN'T SYNC 2.688 ct: 0.000 255/255 40% 258% 3.4% 27 0

but the png's look good
