New info on AVC intra native vs Prores?

[Walter Biscardi]

There’s no difference as far as we can tell. AVC-Intra edits in a ProRes timeline anyway. We bring all AVC-I footage in natively.

ProRes might minimise render times in complicated projects but also take up more space and L&T time. One thing that Gary Adcock has been saying here for a long time is that ProRes422(HQ) is not necessary for frame sizes up to 1920 x 1080 and in fact may cause issues apart from bigger files and higher data rates needing faster drives.

Both Walter and Shane Ross recommend ProRes timelines for complicated sequences that include long GOP native codecs and lots of graphics elements. As someone who grades and onlines I can say that I have not had issues with simple long GOP timelines going through Color (1.5.3) so it boils down to what works best in the edit.

If you want the best interoperability with other systems, and LIMITED render times…bring it is as ProRes. AVCintra does not have sequence settings, so you need to use ProRes anyway. And if you use AVCI in a prores sequence, you need to render right away (well…green render so not really). Coming in ProRes on a ProRes timeline means zero render bar.

And this means that you can share the ProRes file with ANYONE. AVCIntra requires a driver be installed.

Personally, I’d import as ProRes to keep things simple. And it will look fine…match exactly what you see natively.

AVC-Intra is not long GOP, acutally the opposite. It’s CBR constant frame.

I edit AVC-I native all the time, but then again I don’t log and transfer (I edit uisng the MXF files). It saves oodles of time and disk space as I don’t have transcode eveyr single frame before editing, even if the timline has to render. It’s still samller than making evey single piece of your footage ProRes. I usually finish in Color and at that point render out ProResHQ. if for whatever reason you need to bounce a file out to AVC-I, MXF4mac has an AVC-I encoder.

Thanks – everyone. I also just got an email from a friend at a big post house in Hollywood – he suggested I import as Prores
for the savings in render time as well (at the cost of longer log & transfer – but thats 1 night per shoot of thinking – not endless rendering
as I go). He also agreed about the prores vs prores HQ.

THANKS again.

Thanks,
Harry

You’re going to need an Intel machine for Avc-I ingest.

Hello,

I just read you string on AVC intra versus Prores. I was under the impression that the FCP would import AVC and work natively so that ties with what you are stating. The considerations to the best of my knowledge on a long form project would be a fast processor i.e 8 core with a good amont of RAM.
I have a shared storage solution 10TB via gigabit ethernet connection that is setup between two off FCP systems running version 7.0.
Does this sound feasible to you?

Many Thanks,

Allan
