Export uncompressed FullHD video. Premiere CS6

Hello.

I have a problem, and I want to ask you for some advices.

Actually I have an Intel Q9550 CPU on which I edit my videos. I didn't have problems with Full HD untill I started to work with AVCHD Format.

The problem consist in Exporting time (it takes very long ~ 7 Hours to generate a 90 minutes movie with VBR 1 Pass + Render At Maximum Dept + Use maximum Render Quality, 1920x1080 25p).

I have a colleague which has an Intel i7 3770K, which does the same process in less than 1 hour.

I'm curios, is it possible to export from my Q9550 PC an uncompressed video. After that to Import this video on i7 3770K PC and compress it into MPEG2-Bluray and MPEG2-DVD. ?

BTW:

Actually I cannot change my PC because i have no budget allocated for it.

Also, please exclude the advice to copy all footages to i7 3770K computer, and the project and to export on it.

Any advice will be welcome.

Firstly, you are greatly increasing the render times by checking both Max Depth and Max Quality. Max Depth is typically not needed or used. As for Max Quality, that is said to only help when SCALING is involved, so that would not help when going from HD source to Blu-ray, would only be used when exporting to DVD since you are downscaling the source video. So keeping those rules in mind could save substantial time right there.

But if you do want to export and have your friend encode for you, you don't want "Uncompressed HD" files, those would be absolutely gigantic files and would really strain ANY system when trying to play them (requires special hard drive RAID arrays). Try the free Lagarith .avi codec that can be downloaded (your friend will need it as well to use the files). http://lags.leetcode.net/codec.html Has uncompressed quality, without the uncompressed file size, though the files will still be quite large compared to AVCHD. Your 90 minute program could easily be well over 100GB. A more compact format with good quality is the Matrox MPEG-2 I-Frame 4:2:2 codec, at 100mbps, so about 4x larger than AVCHD files, available here - http://www.matrox.com/video/en/support/windows/vfw_software_codecs/downloads/softwares/version1.0/build33/

Part of your render time issue could also be due to effects you have applied in the video. Those will of course need to render whether exporting to Blu-ray, DVD, or "just an .avi file". So in that case, it may take just as long to export to Lagarith as other formats, so you may not save any time anyway.

What is your hard disk setup? That could be a bottleneck that limits export speeds as well, if reading from and writing to SAME drive, if it's not fast enough.

"What is your hard disk setup?"

Read from Seagate Barracuda 0.5TB 7200rpm / Write to SB 1TB 7200rpm.

"Max Quality, only help when SCALING is involved (...) -> would only be used when exporting to DVD since you are downscaling the source wide"-

Thanks, you're right!

""Uncompressed HD" files, those would be absolutely gigantic"

Oh, yes, I forgot when I was exporting to AVI, and 90 minutes of video occuped more than 20GB.

Thanks Jeff!

Your answer was decisional for me

Glad to assist. And you must have been exporting as "DV AVI", as 20GB sounds about right for that since DV is 13GB per hour. Uncompressed HD would have been exponentially larger than that.

Why?  The original footage and project file will probably take up less room than an Uncompressed export.

Instead of 'uncompressed', you should use a 'lossless' export.

(No guarantee it will be quicker than your previous attempts)

Appropriate codecs:

Lagarith Lossless Video Codec (pc only)

http://lags.leetcode.net/codec.html

Ut Video Codec Suite (pc or mac / lossless)

http://www.videohelp.com/tools/Ut-Video-Codec-Suite

Avid Codecs 2.3.7 - DNxHD (pc or mac) / 'virtually lossless'

Thank you for the list of Codecs Joe!
