Question

Full Screen Preview is displaying different timing than the Program screen

I am using the latest version of Premier Pro (Version 24.1.0), an M2 16in Macbook Pro with 64 gig of ram running Sonoma 14.2.1, and three 4k ThinkVision monitors that are 99% sRGB. Playback during editing 4k is smooth and I have not had issues until turning on the full-screen preview monitor.  

 

When editing, I am using one of the monitors to "Transmit Device Playback" to it in 4k.  The issue I have is that during playback on the timeline, the playback screen changes the video 1 frame (sometimes 2 frames) before the Program monitor. So, when watching the screen to review the edit, you see the preview screen change just slightly BEFORE the program screen.  During client review, this is seriously frustrating.  Not only does it throw the timing of the music and voiceovers off when editing to the beat, but in the side of your eye, you can see the Program screen change 1-2 frames later, and that then shows the client the issue.  I have had several people notice it now since we are really working on trying to hit the beats while editing corporate videos.

 

Is there any way to add a 1-2 frame delay to the preview screen transmission? 

 

If the Preview screen changed AFTER the program screen, I would say it may have to do with a laggy HDMI connection of the 4k signal, but it's changing BEFORE the Program.  Weird???

 

Any ideas???

    It's not code, but yes, that's how you'd plug your frame rate into the forumla. So, in your case:

     

    (1/29.97)*1000 = 33.367 ms/frame

     

    You can dial this in down to the millisecond.  This forumla was just to help get you in the ballpark since the offset uses milliseconds instead of frames.  You said that the 4K monitor is displaying 1-2 frames early.  So to delay it by one frame, you'd add a 33ms delay.  To delay by two frames, you'd add a 66 or 67ms delay. 

     

    But maybe you find that 33ms is not enough and 66ms is too much... the offset is not exactly 1 frame or 2.  You can dail this in to whatever you need to... say it turns out that 53ms is the sweet spot.  You can do that.

    Thank you for the reply.  I will try this.

     

    I am using 29.97 frames in the sequence settings, so is this how the code should look to delay it 1 frame?

     

    [ms duration of 1 frame] = (1/[29.97])*1000

    Go to Premiere Pro > Settings > Playback and try adding a Video Offset for the monitor that is your 4K Transmit Device. This will delay the transmit video feed on this screen only.

     

    For some quick math to get you in the ballpark:

     

    [ms duration of 1 frame] = (1/[your frame rate])*1000
