CANON C300

Hi guys,
I know that this topic was discussed a little bit before, but I still need your help with few questions, regarding Canon C300.
We are going to shoot on a green screen, and then add simple graphics after. Very simple video
My graphic artist ask me to shoot less high resolution because of capability his laptop. 
I never had experience with this camera before, and usually shooting only high resolution. 
My question is: can 1080 444 will be still usable for keying, or better not even try to do that?
My final delivery will be for Youtube and Vimeo.

Thanks a lot!

The C300 will key perfectly.  It’s all about lighting  the green screen and subject appropriately.

Hey Irene,

you're correct with your practice so far.
I recommend to shoot at the highest resolution available to you.
You can always output lower resolutions later (provided you have the time and opportunity for that extra work).

If quality is a primary factor for you, keying should be done in the highest resolution possible, especially if the files are lossy compressed.
It just makes for a better final product, no matter the delivery resolution.

Your artist could work like we did in the "good ol' days": offline / online with proxy files before final output.

Consider internet render services for final output if budget allows (they're quite affordable these days).

Depending on your / the artists situation another viable alternative could be to rent or purchase a workstation for full resolution work.
A plain PC for about 1000 EUR with 16GB RAM, a decent graphics card like the nvidia gtx980 and enough HD space for the shots and renders is perfectly fine.
It won't be smooth 4k playback for the artist but VFX work is absolutely doable.

hope this helps,
enrico

Looks like you might have a C300mk2 since you mention 444. If so, 1080/444 12bit is good and internal codec is also fatty enough for green screen. But do lower the ISO as much as you see fit. I would consider ISO 200 for Green screen.

If it's C300mk1: Use external recorder for better codec. All rez and sampling is 8bit 422 1080. ISO selection depends on noise vs highlights. IMHO camera rolls off highlights best at 500 iso and WideDR, but you might want lower noise for better key and sacrifice the highlights.
