Subtitles in Caption’s widow really slow

[fernando alves]

I am working in a 15 minutes a movie and need to subtitle this film. I am doing it at the Caption's widow. And it is incredible slow.  Really simple timeline. Movies in Pro Res Proxy, timeline set up in Pro Res Proxy. When I am writing the subtitles in the Caption's window it get hard to write in real time. Why is it very slow? Is there another way to make subtitles in Adobe Premeire Pro 2020? It is so annoying. Running a AMD Rayzen 7 2700x 8 core, GPU Vega 56, 32 gb RAM. Thanks

I don't know why this would be so slow. Please provide a screenshot showing the timeline, and the Caption panel.

What is the pixel size of the sequence and the caption stream?

Hello Stan, 

Sequence Pixel size: 1920x1080

Caption Pixel size: 1920x1080

I assume it is something other than the captions. I would turn off visibility (eyeball) on track 4, then track 7, then all tracks other than the video and captions. If that still doesn't do it, create a sequence with just a 1920x1080 (nonproxy) video and the captions.

Let know if that helps the speed. Simple turning off the adjustment layer would be a workaround while you do the captions. If it only works when it is on its own timeline, then we'll take it from there.

Stan, thanks a lot. I unable the all the layers, but the video clips and it works very well. Typing my Captions in real time.

Should I create a new sequence as Preview File Format >I-Frame Only MPGE, instead Preview File Format >Quicktime - Codec > ProRes Proxy? 

I came from Final Cut 7 and I allways setup my sequences as Apple ProRes. And I never understand the I-Frame Only MPGE when I migrated to Premiere. Why Adobe Premiere sequence default codec is I-Frame Only MPGE? 

Nice one, Stan.

I'm not a proxy expert, so I'll leave that to someone else. If it is slow for non-caption performance when you turn the layers back on, I'd reconsider your workflow.
