[Premiere] - Playback glitch when speed ramping over 800%?

Hey Guys,

 

I have been encountering glitches in playback while trying to speed ramp over 800%. The project is being edited by a windows user and then he is archiving the project and sending it to me where I then open it and finish it. The glitch happens during any playback or scrubbing in the timeline and it is glitching to an entirely different clip than the one I am trying to ramp.

 

I have deleted all of the cache files and have even tried starting a brand new cache file for the project but nothing seems to fix it. I have been working with this windows editor and this workflow for over a year and have never encountered this until the most recent projects. We are both running CC 2020. Any advice or possible solutions would be greatly appreciated. I have attached a sample of the glitch below.

Does the problem remain if you render the clip?

No, Upon Rendering I simply get a freeze-frame the second it breaks the 800% barrier. You can see in the example it plays fine during the ramp-up but right at 800% it freezes for the remainder of the playback.

I had a very similar problem with speed ramping, but when I exported the video the glitch wasnt there in the export. Try rendering the clip on your timeline and see if that helps!!

Hi Decon,

 

We're sorry about this. We are aware of a similar issue. Please let us know the exact version of Premiere Pro that you are using. Also, try this workaround and check if it works. For the sections where you need more than 800% change (for example1600%), try nesting the clip/section with 800% change and then apply the 200% change on the nested clip. Let us know if it helps.

 

Thanks,

Sumeet

Hey Sumeet,

 

Thank you for the response. I am running Premiere 14.0.3 on MacOS 10.14.6. I tried the nesting technique and did manager to get some playback while it seems to still lag once it starts to reach a higher "buffer rate" (Not sure what the terminology is here but if I start the playback further ahead of the ramp I get the glitch but if I start right before the ramp it works most of the time). I have attached a video below to show you and this will certainly work for now until you guy get it fixed on your end. thank you for all your hard work and such a great product!

 

Cheers,

Devin

Hi Sumeet,

 

I'm also experiencing this playback issue with speed ramping, making it practically impossible to edit efficiently.

Has a bugfix been released for this yet?

I have exactly the same problem, if I set the speed above 800% my preview image is going crazy. It is almost impossible to edit like this. Very annoying!
