Okay, thanks. I guess it’s not possible at the moment then.

I know that lossy normally lessens the image quality in the compression process, but Curtail has two options:

Lossless mode: Compresses the file by removing unnecesary data that does not affect image quality; thus reducing file size. Lossy mode: Compresses the file much further by lowering the visual quality of the image; thus reducing the file size but looking a bit worse.

After using the lossless mode, I’ve personally done very thorough image comparisons to see if there was any discernible difference between the original file and the compressed file. I could not find any visual difference.

In Curtails own words on their site “It supports both lossless and lossy compression modes with an option to whether keep or not metadata of images.”

In that case, what I mean to say is that I want a program that compresses the video in a way that is not perceptible to the eye, while also preserving metadata and reducing the overall file size.

I’m not sure why “lossless” is not the right term, because that’s the term that curtail itself uses within the app. Is the term misleading? The app is designed for photos, not videos. It compresses each photo without losing any quality, and slightly decreases the overall file size without losing metadata. I want a program that can do the same thing with videos.

The console UI is just the Steam Big Picture mode but unlike desktop Linux is loaded into at startup. Although loading it at start up can also be enabled on Linux desktops even if you aren’t using SteamOS.
