Insane Render Times and other bugs
I know there has been alot of talk about long render times but I just wanted to see what others have experienced.
We are really trying to evaluate Premiere to see if that is our next editor but these render times could be a huge roadblock.
First the system, had to edit and render this show on a Macbook Pro(2011) with 16gb of ram since our towers were tied up.
The show: very basic corporate communications, 30 minutes all shot in a studio that goes to a shared storage system (Omneon) recorded XDCAM 35 mbps.
This show is basic, talking head with some still graphics over.
Render time: 2 hours. Rendering to ProRes. I tried different codecs, still long render times. The only other thing to mention is, this is HD footage dropped on a SD timeline. To compare, I took the same HD footage, put it on a HD timeline and rendered, still even longer times.
Am I crazy? Are others seeing these insane render times.
Another bug, use Titler, went back and changed the title and the title squeezes in showing video on the edges, kind of like center cut. Renders fine and eventually corrects itself magically.
Just want to know what kind of experience others are having.

Hi Michael,
Assuming CS6 here. Rendering time is directly tied with processing, and while you haven’t mentioned your MBP model, until very recently, they were only dual cores. While we use them as well on the field, they are far from optimal for any type of rendering.
You are also scaling (HD to SD), and if you checked “use maximum render quality” in your export settings (which you should for any scaling), you will get a huge render time hit. In that case we are talking at least triple the time of a standard quality render. Make sure you uncheck “use max render quality” when not scaling.
Sorry, I have not experienced your titler issue.

[Michael Hendrix] “Render time: 2 hours. Rendering to ProRes.”
ProRes is processor intensive and in fact all Rendering is processor intensive. Do you have any filters at all on the video, like color correction? That will slow you down exponentially.
I have found that CS6 renders much faster than CS 5.5

Thanks for the tip on “maximize render quality”. I will do a test with that so at least I have an option for quick render.
Walter, no filters. Very basic studio shoot so no CC.
The MBP is a 2011 2.2 GHZ i7. The crazy thing is we did try to render on a tower (2011-12 core) and the render times were still long.
Walter, since you do long form work, what kind of render times are you seeing on your shows?

Hi Michael,
Since CS5, Premiere can accelerate a lot of things using select Nvidia graphics cards. On the Mac Pro, you’ll have the Quadro 4000 option, but nothing for laptops, so you will experience a performance hit versus a similar PC with Nvidia technology working for you.
Thanks
