Question

Speed ramp broken - shows wrong frame when scrubbing or going frame by frame

I'm interpreting a 120 fps clip in 25 timeline and encounter this error.  Attached a vid showing what's happening. After time remapping, I try and move forward in timeline one frame at a time and it randomly displays a completely different frame (the same frame everytime). 

 

This makes it impossible to find the exact part where you want to slow down the clip. What can I do? 

 

Using version 14.0.4

V 14.3.1 here. I am having this exact same problem. I'm using ProRes... playback is fine, but scrubbing is not.

I'd love to try this in the latest version of Premiere, but it crashes constantly... so I had to revert from Catalina to Mojave, and back to 14.3.1 for Premiere. Now it operates smoothly.

 

Frustrating software.

I'm noticing this as well. Never used to be a problem. Scrubbing through any time re-mapped clip on the timeline shows the wrong frame. Needs a fix asap.

If you just convert the 120 clip to 25 fps with an intermediate format your problem would probably go away.

Ann, what's your workflow?

 

So I'd take all my .mp4 hi res clips - convert them to cineform hi-res (match source settings etc) 

 

And then when every single file converted, I could use the normal low-res toggle proxies on / off workflow?

 

I'm on PC - so Isn't prores for macs?

So after countless hours on support chat with Adobe, problem is known error in version 14. And the fix is to revert to 13!

Did you try just using the clip as is, without interpreting the footage, and just slow it down in the timeline?

 

(FYI: ProRes is found under QuickTime)

No - spoke too soon. 

 

Even if I create cineform proxies and toggle proxies on. The issue still remains. 

 

When scrubbing through it plays a random frame for a second, not the next one in the clip. 

 

This only happens when interpreting footage. Any ideas?


So to be clear: on 23.976 timeline

 

  • Using 60 fps footage interpreted as 23.976 = glitchy frame playback (the file straight from camera - .MP4) 
  • Using 60 fps footage interpreted as 23.976 = glitchy frame playback (after creating prores or conform proxies and toggling on) 
  • Dropping that same proxy from above directly into the timeline (so not using the normal proxy workflow)  = perfect playback and scrubbing.
