Need to speed up my encoding!

[Tero Ahlfors]

Don’t use previews and is there a reason for the frame blending to be on?

Here are some possible issues:
1. Going from h264 to H264 ain’t working. Try encoding to a higher quality codec, like prores or animation or photojpeg. See if it will do it any faster (just do a 15-second clip or something). See if the encode time differs much.
2. Data transfers are slow. Could be you are working off a thumb drive, or right off the sd card you shot with, or perhaps exporting to a thumb drive or sd card. Terrible ideas, all! Or it might just be a slower USB drive, and you are reading AND writing to it.
3. Memory management. Have you fiddled with the memory settings in the prefs? Maybe you should fiddle some more, or perhaps UN-fiddle them….
4. Memory sharing. You have a dozen othernappsnrunning, and there isn’t enough memory for ppro to do its thing….

If it were me, something else I would explore is converting all the source h264 to a different codec, like prores or dnxhd. I know ppro can work with h264 in real-time, but it is a lot more taxing on the system than if you were using a standard editing codec.

Could it be that your friend has an Nvidia Graphics card? Cuda enabled cards do accelerate the h264 encoding, but unfortunately your card is an ATI one, which doesn´t admit CUDA acceleration, only Nvidia cards do. The fact is that filters sharpen and lens distortion correction you have applied are rather heavy going.
Another thing is that the best option to make the export is sending the render files to a different hard disk from the ones where operating system is installed or original media placed.

Hi Victor,

The problem is very simple – the Lens Distortion filter renders extraordinarily slow, even on my Core i7 hex-core X79 with Quadro 4000 and 24GB RAM!! Looks like you are on a laptop, so 5 hours seems quite reasonable.

[Gabriel Sanchez] “Cuda enabled cards do accelerate the h264 encoding,”

That is not true Gabriel. The CUDA cards DO help by accelerating certain features on the timeline, but they do not accelerate h.264 encoding.

Adobe info sheet…

Here’s a list of things that Premiere Pro CS5 and later can process with CUDA:

some effects (complete list at the bottom of this post)
scaling (details here)
deinterlacing
blending modes
color space conversions

It’s worth mentioning one set of things that Premiere Pro doesn’t process using CUDA: encoding and decoding.

Dear Tom, as nvidia says in this article, CUDA do accelerate h264 encoding, al least that´s what i understood (sorry it´s in spanish):

In this other place (https://www.studio1productions.com/Articles/PremiereCS5.htm )there are benchmark tests using timeline Rendering
MPE GPU Hardware and Time Line Rendering MPE only Software. It´s not h264 encoding but Mpeg2 dvd, and there are big differences in encoding times, so cuda seems to be affirmatively affecting in rendering times. See point 9 in the article.

Im just reporting what Adobe says about its own software. CUDA only affects certain properties designed to take advantage of it. Encoding and Decoding do not use CUDA. Go argue with Adobe if you disagree 😀

That is because so much takes place when you encode video. The encoding itself is just the process to convert to a new format. All the other processing has to still take place which includes decoding the raw video and rendering each of the effects on the clip. By using gpu enhanced processing it will be the process of scaling, and rendering certain effects that are sped up and not the actual encoding to the destination format. Overall it looks like the encoding is faster but only the effects part of the chain is sped up.
