Extremely slow render and export speeds in Premiere CC

I have been using FCPX for about a while now and really enjoyed the format of it, it seemed really intuitive but on some level I really felt it was too simple and lacked the fine-tuning capabilities of Premiere, which I used to use in CS3 days.

One thing I did love about FCPX was the render and export speeds. Rendering was really fast, and to export at full quality took seconds.

I have just started a trial of Adobe CC. I do graphic design and photography as well so thinking of paying out the monthly subscription for ease of use, to have all the software in one place. Because of this I am going to give Premiere CC a go as well

I have given Premiere CC a test spin today with some footage from a 5d III. Upon rendering, with colour correction, some warp stabilization and not much else, the render time for my 1 min 40 sec video is saying 1.5 hours. I put it on to export at an earlier stage when it was rendered, and it said 2 hours for export.

I can't work out, through all my googling, what is causing this. I am on a mid 2010 MBP, not the ideal editing computer, but in FCPX I was getting lightning exports.

Anyone got some advice for someone a bit lost as to what he's doing wrong here?

Thanks
 
I think you're comparing apples to oranges here. Premiere Pro is NOT FCP, so first thing I would recommend is to try and stop making any comparisons. Work as if you're editing for the first time. Read the Help file for PP, learn how IT works, instead of trying to translate how FCP worked.
 
The Warp Stabilizer is VERY slow, so don't apply that when trying to compare export times, skews the results.

Please post a screen shot of the export settings panel, perhaps there are settings issues that we might see. But definitely turn off stabilization and see what it says for render time.

What format is the source video and what are you exporting to? Many factors to consider.

Thanks

Warp stabilizer usually tries to stabilize the entire length of any video clip, even if you are only using a tiny fraction of it. In addition, WS is doing all sorts of 'magic' that will challenge the computing power of even the most powerful PC. I would agree that that is the first place to look when troubleshooting long-render times. Transcoding from highly-compressed video formats can also slow things down.

Turn-off WS and let us know the result. Then we may be able to help you find a workflow that allows the use of warp stabilizer without quite such long render times.

Are we sure that Warp Stabilizer is the culprit? I only ask because I was under the impression that WS did its dirty work in the timeline. I cannot say this is actually the case, however.

Unusually long render times for me have come from After Effects comps without RAM previews, linked in through the ol' Adobe CC pipeline.
 
what GPU are you using? up to recently you needed to have at least a "1 GB" video card in order to engage GPU acceleration. less than that you only got the "Mercury" software engine that basically leaves your computer to do things for you and its really bad and CPU fills up fast. that was my first experience with PP and the bigger GPU's i got soon after that made a HUGE difference.

I'm on a 2009 8 core with 32 gigs ram. the key for PP is the GPU. for awhile i had a flashed GTX680 / 4GB with 1536 CUDA cores then last year i upgraded to a flashed GTX780 3GB with around 2300 CUDA cores. if you only have a card like the 5770 (one gig) then its quaint at best but at least there is some GPU acceleration but it maxes out with a few plugs from my experience with that card.

your GPU makes all the difference when working in PP especially in the timeline for RT performance. on export i won't say its the only thing doing heavy lifting and the CPU seems to still plays an important role.
