Convert Apple ProRes 422 HQ to Apple ProRes 422
on Jul 6, 2012 at 8:11:19 pm

Greetings,

I am preparing to edit my Apple ProRes 422 HQ files in FCP but now realizing HQ is overkill- Apple ProRes 422 is sufficient.
I wish I had known in the first place, but now I already have the HQ files!

Suggestions on the best/easiest/fastest/ way to make the conversion?

(I would prefer NOT to go back to the original 5D camera files and convert those to 422, if possible).

Thanks,

rR

Stick with the HQ, why convert again? You've got the good stuff, time to start editing.

Thanks- except that, without hijacking my own thread(!), I've run into playback problems now that I'm needing to edit a multicam/multiclip section...

Needing to run 2 to 4 video streams at times.

My 27" iMac/FW800 setup won't "cut" it!

Hence the need to go to a less demanding (without compromise to 5D file quality!) codec...

Easiest way is probably with Compressor or MPEG Streamclip. Just queue up a batch of files and let it run.

For future reference when shooting 5DII or 5DIII footage there is little value in transcoding to ProRes (HQ). Good old ProRes is sufficient, unless you know of a reason why you'd need the added data rate of (HQ).

Yes, thanks- now I know!

Hopefully I will be able to run multiclips smoothly...

Even with regular ProRes 422, you won't get 3-4 streams via firewire 800. 2 maybe. 3 if your lucky. No way can you get 4...and I'm still not sure you can get 3.

Following up on what Shane said....you may need to drop down to ProRes (LT) or even Proxy to do your edit and then relink to your high quality (HQ) files afterwards. Basically an offline to online style workflow.

Do some tests before you commit all your files to whatever format.

Ok!
Did some tests:

Got a maximum of 3 streams to play at ProRes 422.

Questions:

-With BOTH the clips and sequence set exactly the same format, when dropping a clip into the timeline FCP asks me if I want to change the sequence setting to match the clip setting. ??
I say yes and it's happy but nothing appears to change... is that a FCP thing or am I missing something?

-In 2 or 3 stream mode I get the ORANGE render line, but no perceivable stuttering, looks fine; if I render I lose the multiclip view- I can only see one stream in the viewer. Is this normal??
(I always play from the canvas).

A very helpful thread, as I am in the same boat right now. I know it's been a couple years, but I'm curious, raf, what did you end up doing, and how did it work out for your project?!
