It this rendering time to expect?

[Viktor Sloth]

Hi guys,

First: Sorry for asking a question like this, but it will greatly give me understanding about what to expect when dealing with RED footage, and how to handle it since it will be a camera used a lot in the future :shocked:

We just finished shooting our first music video on the EPIC @ 5K 50fps.
Ofcause I was utterly blown away by the quality of this camera and by the quality it puts on those SSD's, but i'm also quite amazed about how different it is to edit, and how data storage suddenly becomes very important!

Well, we finished the edit in Premiere CS6 and i'm a bit surprised of the rendering time, and would like to hear if it's simply what to expect.

I'm outputting in 1080p H.264 with full debayer.
The color correction is done in Red Cine, and grading are done in Looks and FilmConvert. A few clips have NeatVideo NR applied as well.
The project is 4 minutes exactly and takes about 7-8 hours to render!

It's done on a PC with:
i7 3770K CPU with 4,5ghz
32 gb ram
GeForce GTI660TI CUDA enabled by script.

The data are read from a raid array, and written to a SSD.

The CPU are running at 100 % on all cores! Auch.
The GPU are only used at times.

Is that a render time to expect?

Thanks in advance, and have a lovely day!

Edit in premiere, export XML to resolve, grade and render. You 4min project will be rendered in less than 30min @ full debayer. That's on a retina MacBook Pro laptop.

The render times you are experiencing within Premiere are normal. I gave up on this workflow fast.

Thanks Robino!

I have a question regarding Resolve - how do you deal with the XML export?
In this case, we applied some noise reduction on few clips and some nice grains with FilmConvert - does this come along the XML?
And if you mess with speed remapping and stuff like that, how does the XML handle that?

I wanted to make the jump to Resolve for a while, but the above questions kept me waiting!

I have posted some tips a while back about exporting from Premiere. If you are exporting at 1080P it is best to copy your work to a 1080P timeline (copy and paste) and export from there. Also uncheck Maximum render quality. This adds a huge amount of render time, and visually there is no difference. Please see the link for examples.

I think before you learn the premiere/ resolve / premiere workflow and got all your speed changes, denoise and such along you might have spent more than 8 hours... so let it rneder and think of what way to go next time
