Project not playing back after import

[Derrick5C35]

Hey there,

Im having some difficulty in Premiere, I finished a project and I shot the intire project on a dji mavic air 2 drone in 4k 60 fps but there was one shot filmed in 29.97. I slowed all of the 60fps clips down to 50% . I have a audio track in there as well, I rendered it, green lines in timeline section. When I playback the finished project in Premerie just the music plays, and when I export it its the same thing.

Drone footage is highly compressed and not really suited to edit.

Most likely your machine cannot handle the drone footage

Best is to use proxies or transcode to en edit friendly codec before bringing it into Premiere.
