ProRes-yellow?

Posted by John Heagy on January 26, 2012 at 12:03 am

Below is an explanation of what the colored render bars mean.

Simple question: How do I get ProRes to be “none”?

This may be a deal breaker if a long encode is needed to create a self contained .mov

I understand reference movie export is impossible… another huge bummer!

Thanks

OK, so now about those colored render bars…
With that preparatory definition out of the way, what do the colored bars mean?

green: This segment of the sequence has a rendered preview file associated with it. Playback will play using the rendered preview file. Playback at full quality is certain to be in real time.
yellow: This segment of the sequence does not have a rendered preview file associated with it. Playback will play by rendering each frame just before the CTI reaches it. Playback at full quality will probably be in real time (but it might not be).
red: This segment of the sequence does not have a rendered preview file associated with it. Playback will play by rendering each frame just before the CTI reaches it. Playback at full quality will probably not be in real time (but it might be).
none: This segment of the sequence does not have a rendered preview file associated with it, but the codec of the source media is simple enough that it can essentially be treated as its own preview file. Playback will play directly from the original source media file. Playback at full quality is certain to be in real time. This only occurs for a few codecs (including DV and DVCPRO).

Hi John,

The simple answer is it won’t be. Prores is only available because FCP is installed.

The bar will go away for what Adobe calls “native” codecs.

Prores is a closed format, and it will never be otherwise unless Apple decides to…

Are you having issues with realtime playback?

I use Prores on a regular basis (mac side) and it plays very nice on our Macpro 3.1. It also plays fine on our i7 machine.

Thanks Vince,

That’s what I suspected. Not sure what you mean by “closed” or how that has anything to do with being “native”. If FCP is installed (really only Qmaster is required) then Abobe has full access to the ProRes codec on a Mac.

Does anyone have a list of HD codecs that PP accepts as “native”?

We currently use FCP and generate or convert all sources to ProRes so our timelines are always 100% native. We have crazy deadlines and can’t afford to render every frame of an hour long show to export a file. We export QT ref .movs to feed our Episode encoder cluster with FCP. I understand PP cannot do reference movies, but it appears it can’t simply “flatten” out a 100% ProRes timeline either.

Here’s a comparison of the time it takes to export a 55 min 100% ProRes timeline as a matching ProRes file.

PP self contained… 34min, CPU at 40% disk r/w at 35MB/sec

FCP self contained… 9 min, CPU 1%, disk r/w 95MB

FCP reference… 10 secs!

34 min vs 10 sec is bad enough but the fact that PP adds a decode/encode makes it even worse.

Thanks

Hi John,

I am not a software engineer, but the way I understand it, Premiere uses QT to provide support for Prores.

I am pretty sure they could not implement it as part of the program like they do with DVCPro without Apple’s blessing. That’s what I mean by closed.
