FCPX: Covert to Apple ProRes from H264?
on May 19, 2014 at 5:33:20 pm

Hi there,

I understand that usually with H.264 footage shot on DSLR is better covered to ApplePro Res to edit with. I just wondering if this is still necessary with FCX. FCX seems to be doing a lot of transcoding in the background when you import H.264 footage. Is this convert to an equivalent editable codec?
Is it still advisable to convert to ProRes?

If so, what is the best way of doing that these days? I usually do in FCP6 or MPEG stream clip

Also if you do edit a film in FCPX with your H.264 files THEN export as ProsRes when your done, will the end project be the same as is would be having editing as Prores files. And what are the pitfalls of doing it that way round to save time/space?

If anyone can clarify these conundrum I'd be very grateful.

many thanks

Ewan

People on this forum are probably tired of my opinion on this, but here it is again: if you shoot documentary and have enormous shoot-to-use ratio, it is time-consuming and storage-space prohibitive to "optimize" everything you shot. FCPX will handle the AVCHD and similar formats well enough to play back and make some selects. You can convert the selects to ProRes. HOWEVER, if you have a multi cam shoot or want to composite, title or effect the shots right away, you'll want to optimize. Unless you have a lot of CPU horsepower, the h.264 codec is very demanding.

It's hardly demanding at all if you're using a modern processor. IE iMac i7 or NMP. A MacPro just doesn't seem to cut it.

Good to hear. I have found the proxy really helps with multi cam editing on a (recent) MBP. But as per your comment, definitely ingest and look at the stuff natively before making a transcode decision. I regular shoot verite style, which means the camera may run for 6 hours but with one pass I can find the bits I will likely use, and have .5 of selects, to be eventually chopped to a 6-7 minute piece. And if its light on effects, no multi cam, I never transcode to ProRes at all -- until the final output.

The main reason the 'legacy' mac pro doesn't handle h.264 as well as an iMac or MBP is that the Xeon processors do not have hardware h.264 decoding built in.

Are there any upgrade GPUs that have it? I think the 7950 does.

MacPros don't have grand central dispatch support. One of the key technologies FCP X uses in conjunction with avx found in sandy and ivy bridge processors, which are not found on the original MacPros.

[Bret Williams] "MacPros don't have grand central dispatch support. One of the key technologies FCP X uses in conjunction with avx found in sandy and ivy bridge processors, which are not found on the original MacPros."

Really? My understanding is that any multi-core intel mac can utilize GCD. (Although those with hyperthreading do a better job)

the Xeon CPUs in the nMP don't have hardware accelerated h.264 support either, but the D300s-D700s do.

Just sandy/ivy bridge (and I assume later).

Maybe my tech speak isn't perfect. Here's a screen shot from 2011. Don't you love the wayback machine?

I think I was wrong and you were right. it means grand central has ADDITIONAL avx capabilities on sandy bridge. Which has generally been the consensus that that's the reason the older MacPros don't perform as well as the iMacs/laptops with X.

Right, it is the AVX support that is key. My 2011 Macbook Pro 17" is faster than my Hexacore 2012 Mac Pro. But both are way slower than the Mac Pro 2013 Hexacore.

I like editing in prores. It's faster on my older system.

FCPX likes to auto transcode your files on import. That's probably what's going on in the background.

Check your import preferences to change that.

Prores takes up a lot more space, but can always be deleted and regenerated as needed.
