Premiere CUDA acceleration does not work correctly

[Jim Miller]

This thread has been a real eye opener. I’m thinking my problems are GTX 570 Mac (hacked) by Macvidcards related, but after reading this, maybe not. One things for sure, the output quality is definitely unacceptable, not professional, and help is needed. Here is my specific, well tested problem seen on internal scopes and externally through SDI on a Flander’s 2461 monitor’s scopes.

I have been having some problems, maybe because of Macvidcard’s GTX 570 (2.5GB RAM), with Premiere Pro. It took me a while to see and diagnose the problem.

Basically any keyed layers in PPro and their fade up or down (dissolve) is messed up. Simply put some white text over video and put a 10 frame fade up on it. That would mean the transition would be in 10% increments. Instead I get a pop on the first frame (second frame really) of 38% and a fade up to 100% from there. The opposite happens on fade outs, fade to blacks, etc. If you push the background video off to one side, so the graphics is over part black and part video, the difference is quite visible.

When I turn the GPU off in Projects Settings, the problem goes away, except you have to export your final project in the timeline format, and use preview renders, or else the new renders on export will be screwed up also. This problem has been repeatable in other editing rooms with the same card.

Unfortunately, I didn’t notice the problem until after the 60 day GPU card return policy. Is this a universal problem? If not, then maybe there is a cure, so far I and some others haven’t found it.

Thanks much,
Jim

I have to say I agree with Paul on this 100%. I am so frustrated with Adobe Premiere now, I just want to puke. This is program is far too buggy to be released at the price it is at. It has potential, and it is the smartest software choice available, but it is just not ready for prime time.

Must disengage Cuda card before renders and exports to get acceptable fades and dissolves? My renders go from 5 minutes to 35 minutes!

.MTS audio randomly disappears from files. Delete the XMP’s?

Severe lag when navigating H.264 .mts. Shall I transcode?

Relinking of moved large .mts based project? AVCHDs fault for the naming scheme. However, even when manually renaming every single clip and relinking, the audio disappears and the timeline has grey diagonal lines on the clips. I had to start all over on a two day rough cut due to this one.

So Paul. GO AHEAD AND SHOUT IT FROM THE MOUNTAIN TOP!!! Some of us hear you, man. People need to be more helpful and less critical here.

Paul,

You are 100% correct. I have applied drop shadows to animated stills over a grey background. The drop shadow layer flashes a black and grey checkerboard pattern on both sides of the still, but mostly on the left side which has the drop shadow. I have tried GTX680, GTX570 and PNY k4000 video cards and always receive the same result.

If I turn off the CUDA the flashing stops but it takes a lot longer to work on the project. The flashes occur on the monitor and when rendered with the Graphics acceleration turned on.

I have turned off the CUDA and the flashes stop but all sorts of other problems occur. For example when my 4×3 video is not scaled to fill the frame the location of the video moves. Sometimes to the bottom right, sometime to the bottom and usually if that does not occur the video is rendered off center.

Also animated stills shimmer like the sun hitting calm water. These images should not look like the are in motion within the image.

I have 2 weeks to submit to a major film festival and don’t know how to fix this problem.

Also I tried CC and tried to import the project. It rejected all 1,500 MXF video clips. I am not assuming that CC fixes this problem. I do know that Adobe is not certifying any new graphics cards for CS6. They are only certifying new models of cards for CC.

Can anyone help?

Thanks,

I have the same problem. So far I have spent a day on it or so and finally decided to give up. Whatever drop shadow I apply (with AE dynamic link from AE or drop shadow from Premiere itself) with GPU acceleration it looks soft (less shadow). If i turn it off to software only, then it is ok before rendering, after rendering the shadow is gone (almost). Now I just use GPU for the faster editing, then I export from AME instead of exporting from Premiere. So some of the shadows at least come back… If anyone knows a solution to this problem, please let me know. Thanks.
