Hello PDers!

I'm currently using PD11 Ultimate and i'm wondering if i should upgrade to PD12 or not. My question is: Does True Velocity 4 speed up 4K video rendering? Because 4K rendering in PD11 takes so long, so i wonder if it does speed it up. If anyone could just render a 5 or 10 min video in 4K (3840 x 2160 MPEG4) and tell me if it renders fast enough (faster than 1 second video production vs 1 second in real life) then i'd be grateful and i'd upgrade since i need faster 4K video rendering, thanks.

Hi,
The rendering in PD 12 is faster all across the board in my opinion, but the real speed increase is with the new Processor that is out now (the name slips my mind at the moment Hallsway(?) processor ). My signature shows my computer specs and I am quite happy with rendering times.
I haven't done that much with the 4K formats tho' as I don't have 4K player or TV so can't see the point as my euaipment is 1920x1080 format.

Yeah it's Haswell processors, but since they're quad core processors, they can barely render a 4K video, my 6 core intel i7 3930k processor is running at 4.6Ghz and when rendering 4K content the usage in task manager goes up to a solid 100%, as well as ram at 3.5gb, so i dont think PD12 would make it any faster since its already at full load, i could be wrong though.

Hi Jonny93 -

Here are some stats from my PCs, for what they're worth.

PC1 - i7 920 - GTX260
PC2 - i7 3930 - GTX680

Project - 2x4K MPEG-4 clips 3840x2160 @ 21.7MBps & 19.7MBps - total duration 5:40 rendered to MPEG-4 3840x2160 @ 23MBps

Render Times:
PC1 - PD11 - 19:31 (HA) 18:57 (no HA)
PC1 - PD12 - 16:37 (HA) 16:31 (no HA)
PC2 - PD12 - 7:33 (HA) 7:29 (no HA)

Unable to compare PD11 & 12 on PC2.

Cheers - Tony

Thanks for your time. I can conclude that an upgrade is quite useless when the CPU is being used at 100% and i get about the same rendering time when producing a 50mbps 4K video (my cpu is overclocked) so there's little to no gain from upgrading.

True Velocity 4 of v12 is optimized for Intel Haswell GPU 4K hardware encode, so you need a new CPU first...

That's good for quad core users, but i'm using a 6 core which renders 4K videos about 3 times faster than quad cores, so i could see why they optimized it for Haswell Cpus.
