Extremely Long Transcoding Times In REDCine-X

[Christina Choe]

Hi all,

I'm working on a Macbook pro with 3.06ghtz and about 4g of ram and my render times are about 2 hours and 40 odd mins for a 3 min clip. Would it be worth it to get a red rocket card or just try using a faster comp?

Thanks in advance!

Rocket card all the way, and the fastest MacPro along with Rocket card, wouldn't hurt either.

That sounds like render times for a full de-Bayer. Doing a full de-Bayer on a 3 minute clip makes it sound like you are transcoding all of your rushes like that (apologies if I'm making incorrect assumptions.) If you only have a MacBook Pro and no Rocket I would seriously look at an offline/online workflow. You can transcode much faster than that, even without a Rocket, at a quality which is more than adequate for editorial.

I just don't understand how I was able to transcode a whole feature using redrushes rendering each days footage over night and now its going to take over 2 weeks to transcode 750gb. When did they get this whole REDrocket deal? and is it required to get a decent transfer time in REDcine X?

I'm just trying to figure out if its user error. like if there is a setting I'm missing or can change or something. Very frustrating to say the least...

It all points to the fact that you are probably not transcoding with the same settings in REDcine-X that you previously used in REDrushes.

Full quality transcodes have never been fast without a Rocket, so if you were transcoding everything in a reasonable time in REDrushes, you were probably not doing it at full quality (not a problem for editorial purposes.) When you create an export preset in REDcine-X, De-Bayer settings default to "full" unless you change them. I forget what the default in REDrushes was.

Set up a bunch of different export presents using combinations of HD, 2k, 4k and 1/2 and Full debayering to whatever codec you're working with (i.e. ProRes) and see what results you get.

As Nick said, you should consider an offline/online edit if your transcode times are extremely slow.
