Dragging to trim a clip hides all layers above and below it

I appreciate @Astonished_motivation5639 nicely written post, but there are a couple of things I would note.

1) I don't see that option available.

2) I recommend you leave High Quality playback checked (and both Playback and Paused at Full)

    I doubt the transport controls do anything for this issue except give you a slightly larger monitor space.

3) Switch back to Mercury Playback CUDA - if you have an nvidia card

Cheers 🙂

Maybe you've been using Trim mode or Trim Edit, <Shift+T> by default.

I tried it on 2017 also, and it does the same.

Dragging to trim a clip hides all layers above and below it

Giving it another good look, I say its normal behavior.

It only shows the track on which the clip is sliding/trimmed.

while sliding it will give the last frame of the clip on the left or first frame of the clip on the right.

If there is no clip on either side of the sliding clip it would show as black.

If the top and below clips where showing you would not see what you were trimming.

Hey @defaultgzkxy7o55slh 

Hope you are doing fine!

Well that's not a stupid question at all - you're likely dealing with a setting that was accidentally changed. Based on your description, it sounds like "Trimmed Layer Preview" or "Live Preview During Trim" is enabled. Try one of these solutions:

1) Disable Trim / Drag Preview

- Edit > Preferences > Timeline

- Uncheck "Show preview during trimming"

2) Toggle Program Monitor Settings

- Check the wrench icon in the Program Monitor

- Disable "High Quality Playback" and "Show Transport Controls"

- Ensure "Composite Video" is selected instead of "Alpha"

3) Check GPU Acceleration

- File > Project Settings > General

- Switch Renderrer to Mercury Playback Engine Software only

4) Reset Workspace and Preferences

- Window > Workspaces > Reset to saved layout

- Hold Alt (Windows) / Option (Mic) while launching Premier to reset preferences.

This should fix the issue.

You can change this behavior by adjusting a setting in the Timeline:

• Click the Timeline Display Settings (wrench icon) in the Timeline.
• Check Composite Preview During Trim.

With this option enabled, Premiere Pro will display frames before and after the trim point for all tracks, instead of only showing the frame after the trim point for the trimmed track.

However, when dragging a clip in the Timeline, the Program Monitor only displays frames from that specific track. If no frames exist on either side, the monitor will appear black.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.
