Caption is jumpy and shaky (not solved from the sequence setting)

[xid51064546]

I am aware that a similar caption issue was solved by changing the sequence settings, but mine is already with the correct settings.

Here is a short YouTube Video demonstrating my issue in PremierePro 2018, and the produced video looks like this one. You can see the caption is shaking.

As the first video depicts, in Premiere I added caption(srt) into an empty new sequence. when I hit "space" to start playing, the caption blurs and shakes; when I hit "space" to stop, the caption appears clearly. I need to render in/out to see the text.

This issue appeared ~1 week ago in windows 10, and I have not re-installed it or changed settings (as far as I remember).

Here are my troubleshooting done:

• Create an empty project with an empty sequence and add a caption (srt). The issue persists.
• Open a project saved earlier than 1 week, the caption displays OK without this issue. However, if I drag the same caption (srt) once more into the same project sequence OR edit the existing caption, the caption becomes shaking. 
• Change font, size, location in the caption, the issue persists.
• Create sequence with different resolution or FPS, the issue persists
• Deleted PremierePro cache or change the cache location, the issue persists

That is very odd: that the old project with captions works correctly and a new or updated project does not. As noted in the thread that you linked, I was not able to get the shaking when we were working with PR 2018.

I still have 2018 installed and would test when I get time, but I'm not optimistic that I'll see anything. But I wonder about a video driver or windows issue, so perhaps.

Also, I don't think I've ever added captions to an empty sequence.

I did not note your sequence settings carefully. Can you indicate them? Editing mode, fps, etc.

The sequence settings don't seem matter except for the Fields one, but it's already the one that should be right.

In addition, only catpion shakes, background pic (psd) or videos don't have this issue.

I will try to update GPU driver and check the windows updates. Thanks!

PR 2018.1.2. Created a sequence with your settings. Imported simple .srt. Added to timeline. Plays okay. No major quality issues, and no shaking. 

I was using full resolution on playback and paused. When I switch to 1/4 playback, I get pixelation, but no shaking.

My font (default for me) is Arial, size 60, no edge. What are you using?

Your timeline shows red, unrendered, as you say. I have yellow. In your project settings, what do you show for CUDA?

Thanks Stan, I found the cause! Indeed the GPU driver.

Mine is AMD Radeon rx580. The device manager says the display adapter doesn't function properly and the Radeon Setting can't open.

Likely the recent windows update screwed it up. I manually uninstalled and reinstalled the latest driver. Now the issue in Premiere Pro is gone.

I didn't think of GPU driver in the first place because the monitor resolution, Premiere pro processing time etc. all remained the same as before when the driver was working well, and I didn't use this PC to do anything GPU heavy except Premiere pro video editing. 

Thanks again!

Excellent! Thanks for reporting back.
