AVC-Intra format
I have a question regarding how Final Cut Pro handles AVC-Intra footage. We are looking to purchase a camera that shoots in the AVC-Intra format. If we shoot in AVC-Intra 50 (50Mbps), will Final Cut Pro edit in that format natively, or does it need to be converted to another format? If it does edit natively, does that format require a lot of processor power? The reason I am asking is that I was wondering if the AVC-Intra would take a similar amount of storage space as DV50 footage (what we had in mind when we built our server), or if we need to plan for a larger storage space. Thanks for you help!

HD formats, good ones, have higher data rates than SD. Only HDV has a lower data rate than DV50.
FCP 7 imports ACVI native, but there aren’t any AVCI settings for editing. No encoder. You’ll have to edit on a ProRes timeline, and render everything when done. Or import as ProRes and work that way. Or if you have a lot of footage, and little space, import as ProRes Proxy for offline editing and reimport at full res later.

I’m with Shane… best to capture as prores files from the get go I’d think… faster renders, faster compressions etc… and no need to render all in the end.
AJA has a sweet little app for you to figure out data rates and storage space needs for them: https://www.aja.com/support/konaNEW/kona-3-3x.php it’s the data rate calculator about 5 up from the bottom of the downloadable files there.

AVCI 50 and DVCPro 50 are both 50 Mbps. Which is a pretty neat trick, to get a good quality HD codec to run at the same data rate as a SD codec.

MXF4mac has an AVC-I encoder, but it is pretty slow compared to ProRes. you can use ProRes LT if you want to keep your file size down. If shooting AVC-I, I’d shoot 100, though, unless you really need 50.
What frame rate are you planning on shooting?

Thanks everyone for your posts. It looks like I would be best to go to ProRes right from the start to simplify matters. We will primarily be shooting in 1080i60 with the AVC-Intro 100 format.

It takes a long time to transcode. AVC-I is much faster, and the render times in a ProRes Timeline are negligible. We do this all the time, but then again we use native MXF files as well. It’s much faster.

If the render times are not that much of a factor then we might give that a shot. Thanks.
