Hello,

First of all, as far as I can read here, 2.7K 60 fps captured with a GoPro 7 has an aspect ratio of 4:3 and is recorded in HEVC (h.265) codec. HEVC isn't supported by Lightworks. If true, you will have to convert prior to import.

Second, 2.7K Gopro isn't a standard broadcast format. You have to decide to up- or downscale to 2K (1080p60) or 4K (2160p60) and, if captured in 4:3, 4:3 aspect ratio isn't supported by any HD standard I'm aware of, so you'll see black bars left and right in 16:9 frame.

Would you mind posting your computer details (OS/version, CPU, RAM, GPU, HDD) and a Mediainfo report of the footage. That would help for further advice. Here you'll find information on how to create and post Mediainfo reports.

Does that affect all frame rates?
I see in the project settings "2k full Frame" when I use 24 and 48 fps projects. Visually, this seems to be 4:3 (within Lightworks).
Is there no corresponding export format for "2k full Frame"?
Maybe with Quick Time, or an image sequence + audio as intermediate formats, and post-processing with ffmpeg?

With HD standard I meant broadcast standards.

DCI Full frame in 2K and 4K are film formats in 4:3, that's correct, but as far as I can see, on export only available as image sequences.

Of course you can use a multi step conversion with third party software to do things, beyond the limits of Lightworks, but my intention was keeping unnecessary complexity out of this discussion at the very beginning.

As you can read above, I'm not even sure that the GoPro footage mentioned is supported natively without conversion due to HEVC codec. We will see.

Schrauber,

Do you know, how does Youtube and Vimeo deal with 4:3 aspect ratio? Does the effort to create 4:3 pay?
