Exporting DVCPROHD for rotoscoping
I hate the DVCPROHD for one reason really, and that is whenever I have to hand it over to someone rotoscoping on a PC they can never seem to read the codec. Now most rotoscopers like to work with image sequences I have found. If I export an image sequence from FCP using that format, it comes out squeezed (because of the whole 960×720 crap, I think). Now if I try to do it another way, by first exporting in the native codec from FCP, and then from that export from QT player as an image sequence, then the images come out the right aspect ratio, but if I compare a frame from the image seq to the same from from the DVCPROHD clip, it is horribly pixilated. The only solution that I can see is exporting from FCP in a format that the pc can read (i.e. Animation or uncompressed). I tend to do animation, cuz in the motion gfx world, it seems to be the codec that everyone feels safe with (though I think I would prefer an all 10bit world). If they insist on an image seq then I will make it in QT player from the animation export. This seems like a waste of time and space. Is there a simpler way for me to spit out a good looking image seq from DVCPROHD (pref straight from FCP).
Thanks a bunch guys,

If you want to export DVCPro HD as a square pixel image sequence, you need to export it from a square pixel, uncompressed timeline. Simply drop your clip (or clips) into an 8-bit or 10-bit UC timeline & export from there.
Another trick, is to export your image sequence in it’s native, anamorphic state, & then run a macro in Photoshop to resize the image sequence. I think you can probably save the macro as a droplet.

Hey Thanks Arnie,
That makes sense, forgot about the whole non-squareness thing of the DVCPROHD codec, or rather ignored it. As far as the photoshop droplet goes, yeah I thought of that (and think I even did it once), but it just seemed messy to me and no easier than my other method of making exporting first as animation or 10bit and then making an image seq from that. -

You can also export from a ProRes timeline which is square pixel.

True. I didn’t want to get to complicated.
