Render Time - does it make any sense??

[dori_bashan]

Hi,

How much time take you Red users out there to render from 4k footage to Quicktime DNxHD 175/185?

I'm working on MacPro Dual Quad Core with 4 GB of ram and it's taking about 27 hours to render 1 hour footage using RedRushes.

I'm tried from a f/w 800 drive and also from an internal 3 disk Raid and the results was the same.

does it make any sense???

Thanks

It sounds about right if you need the full quality for online.

But if you're preparing footage for offline I would suggest you choose half res or quarter res instead. This will be much faster to transcode and the quarter res quality is good enough for offline in HD if you're not screening on a projector.

And the 1/2 rez is good enough for HD finishing - The numbers sound about right for any file type transcode from the full 4K.

you were right, i did use full quality.

what does 1/2 rez means? what happens to the footage?

[Kenn Michael]

1/2 res is referring to the type of 'debayer' the software uses to process the R3D footage.

if you're outputing 4K DPX files, then use 'Full Res'

Like MichaelP said, if you're outputing 2K or 1080P HD files, then use 'Half High' or 'Half Standard'.

'Half High' in a 2K or 1080 output should look indistinguishable from 'Full Res' and should cut your render times dramatically.

if you're outputing 1K, then use 'Quarter Res'.

This is assuming you're working with 4K source footage.

If you're converting 2K or 3K source footage, then you need to transcode at 'Full Res' for 2K or 1080 output.
