I am having an issue with my exports from Premiere Pro. The source video doesn't have any lag and plays fine on the Windows Media Player on the laptop I'm using (PC), however when put into Premiere Pro it starts to lag (just the video, not the audio). I have this problem sometimes but whenever I export the video, it plays fine and only lags in the timeline. I've never encountered this issue before where a video that wasn't lagging before, after edited in Premiere Pro, now lags after being exported. It is also mostly just the video and not the sound, which is also confusing. Is there any way to fix this issue? I've included a screenshot of the export settings.
The source footage at 8fps is a screen recording from Zoom, which is probably why it is so low. I also have another video in the timeline that is at 29fps (which is probably why when it's added to the timeline it starts to lag). Would you be able to tell me how I can change the fps of the export settings to match the source videos, and how can I maybe preserve the fps of the higher quality video in the timeline?
