Shooting “high-speed” 7D, end-delivery PAL

Posted by Erik Lindahl on October 7, 2010 at 12:37 pm

I was wondering if anyone has any “do and don’t do’s” regarding shooting high-speed with a 7D for delivery in PAL. We’re juggling to shoot with 50 or 60p, are there any pros / cons / issues with either-or? Our end-format will be PAL (720×576 16×9 FHA 25 fps). Does a specific format work better or worse if editing and grading / comping in Final Cut / Color / After Effects? Are there any “think of this when shooting”?

I’d presume we convert all video to ProRes 4444 25 fps at ingest.. We’re do we do this best? Through FCP or an external app?

I’m quite used to working with higher-end formats (Film / RED) so the DSLR stuff is quite new. I gather we have to treat the set like video and be really careful with over and under exposures.

I can add to the above the set will be very controlled and we don’t (I don’t think at least) have a lot of motion to suffer from the dreaded shutter distortion. We’re shooting bubbles as far as I gathered (whine / soft-drink “sizzles”).

Thanks for the reply! Normally I\’d go with ProRes 422 HQ but the issue is the After Effects has a very nasty bug when working with this codec in conjunction with a Kona 3 card on OSX. The solution here is ProRes 4444 or render in 16-bit in AE. Here I prefer larger files over longer rendertimes through the entire post. But I get what you say.

Does the Canon Log and Transfer re-wrap 50p media to 25p? Does any other tool do this? Did some quick tests last night and AE seems to do it fine but that\’s a bit \”brute force\”.

Erik,

If the bug is a gamma shift, remove the following from /Library/Quicktime
AJACodec
AJAUncompressedCodec

and restart

It’s the “rainbow color effect” bug I’m referig to. Gamma-shifts seem not a probelm with ProRes 4444 at least in CS5. Yes, removing the codec would love my problem, trouble is we’ve had projects using AJA 10-bit RGB codec amongst other things.

Yeah, I know and I stand by the fact I need video output, I need the Kona codec and I’d rather have larger files than longer rendertimes even if ProRes 4444 is overkill 🙂
