Premier Pro Slow Motion is jerky (not smooth) when exporting with Mercury Playback GPU Acceleration

[Abdul_Majid]

When rendering slow motion video clips (video slowed down to, for example, 30%), with Mercury Playback GPU Acceleration and with frame blend enabled, the rendered video is not smooth (is jerky). Frame Blending does not have any effect on the rendered output , The results are identicle with and without Frame Blend.

When software only rendering, and with frame blend enabled (ticked), the resulting video is smooth motion.

Please take a look at the following which demonstrates the issue:

I am using the following:

Windos 7  64 bit

Premier Pro CS5.5 (with latest updates)

NVIDIA GeForce GTX 570 (with latest driver)

The video I am rendering is HDV 1080i format..

I have tried exporting in MPEG2 and M2T with Max Render Quality ticked. Both formats produce the same results.

Why does Frame Blending have no effect on slowed down clips when exporting with Mercury Playback GPU Acceleration? Is this a known issue?

First, I have a video showing the slow motion problem in CS5.5 and CS6.  CS5 seems to be okay.  Here it the link to the video    http://www.studio1productions.com/blog/?p=93

Also, you can enable you 660Ti to run in GPU mode.  Here is an article explain how and a software program I wrote that will do it for you for CS5, CS5.5 and CS6

Hi

I raised this issue with Adobe back in August 2012 - see above. Adobe have withdrwan the support case I raised with the following comments:

"The case has been withdrawn as it is a known bug & has been reported to our Engineering Team for further research."

So, at least it has been acknowledged as a bug. Hopefully a fix on its way in the not too distant future.

Still no fix

Not yet.  Keep reminding them.

Hi I am having the same issue as you. It started last week all of a sudden. Using Sony A7S3 10 bit, 60 frames a second slowed to half, I am having bad motion blur even with very slow movements on my part while taking video. I don't know what to do about it. I am trying to search for a solution. I dropped back to version 22 2.0 and I thought that fixed it, but no.

God. I'm running into this for months! It's unbelievable that they haven't fixed this since 2014.

Looking for solutions but nothing can help.
