Video Only lags after change of resolution

[defaultd86si8x6189v]

Video plays back fine in native resolution (1920x1080) however as soon as I put it in a 1080x1350 sequence the playback is choppy until I render in and out. Afterewards if I make a small change like scale or postion I have to render in and out again. I'm also using proxies (same issue toggeled on or off)

This is a new issue and havn't run into this before - Have searched everywhere and canot find a soultion anyway. Any ideas?

Hi there,

We're sorry about the poor experience. Let us know the version of Premiere Pro that you are using & the system specifications (OS, CPU, GPU & RAM). Also, is this happening with any specific media type or is it happening with all of them?

Thanks,

Sumeet

Hey Sumeet,

Thank you for the response, I'm using Version 15.4.1 with the following specs'

Windows 10

Ryzen 9 3900x

16GB DDR4 

RTX 3060 

Since posting I think I understand what my issue is. I have a sequence where I place all my footage and the sequence  is set to 1080x1920 and contains 4k footage "scaled to frame size" onece I brought that into the 1080x1350 sequence thats where I was having issues. If I drag and drop the footage from my media browser I do not have an issue. Also, if I drag it from a 4k sequence the issue is also not present. 

So it appears if the 4k footage is scaled to frame size within a 1080x1920 sequence and brought into the 1080x1350 sequence that where the issue is arising. Assuming its due to the scaling of the clip being so inlarged.

Cheers!

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 install 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.
