Dustin Posted December 5, 2016 Share Posted December 5, 2016 What is the thoughts on this as of Dec. 2016? I'm still using an old d5300 on Premiere Pro CC 2015. I don't have the latest update with Proxy workflow but I do have the Lumetri Color panel upgrade which was huge! My computer is currently a 2012 MBPR with an i7 and 8 gigs of ram. I edit on a USB3 drive typically. I usually have no issues editing my projects which range from 30 seconds to up to 15 minutes with my typical work but when using Lumetri my computer struggles. Would transcoding to prores help the overall session speed and would I lose much of anything? Can anyone point me to articles/threads where this was RECENTLY discussed? Apologize if I'm bringing an old topic up and simply need to look a little harder. Can Adobe Media Encoder transcode to ProRes? Quote Link to comment Share on other sites More sharing options...
Cary Knoop Posted December 5, 2016 Share Posted December 5, 2016 I don't think transcoding to ProRes is going to help but you can always try. ProRes and H.264 pretty much use the same compression technology, but ProRes does not use inter-frame compression. It is hard to scrub the timeline with inter-frame compression because the computer has to calculate the current frame starting from a key frame which may not be nearby so transcoding it often helps. By the way you can encode H.264 without inter-frame compression as well. Lumetri functions use the CPU and GPU and do not depend on the codec because they are processed after internal decoding. You could enable 1/2 or 1/4 playback on the program monitor or use lower resolution proxies. Dustin and Mat Mayer 2 Quote Link to comment Share on other sites More sharing options...
Dustin Posted December 5, 2016 Author Share Posted December 5, 2016 Yup typically I just go to 1/2 playback. Maybe I'll try the new proxy workflow in 2017 soon enough. Quote Link to comment Share on other sites More sharing options...
Don Kotlos Posted December 5, 2016 Share Posted December 5, 2016 Transcoding to a CPU friendly codec such as Prores will help A LOT when you want smooth scrubbing playback. Reducing the resolution will help performance when using effects. See this post for more details: Quote Link to comment Share on other sites More sharing options...
Bioskop.Inc Posted December 6, 2016 Share Posted December 6, 2016 Also, you won't need to transcode to ProRes HQ for just H264. Here's a good article by Larry Jordan & he goes through the different uses of transcoding to ProRes - for 8-Bit he recomends just the normal ProRes: https://larryjordan.com/articles/pick-the-right-version-of-prores/ Quote Link to comment Share on other sites More sharing options...

In this article Tony Northrup discusses how to manually use a proxy workflow in previous versions of Premiere: http://www.rangefinderonline.com/features/how-to/Getting-Acquainted-with-Offline-Video-Editing-to-Ease-You-Into-4K-8988.shtml As already stated, I'm not sure that would help with Lumetri performance, but maybe it would free up CPU cycles from constantly decoding H264. The new Premiere CC update for built-in proxy support is really nice -- it is vastly better than manually transcoding and linking up files.
