I have a very very very ugly script to merge multiple files of my football games (I have 10 cameras a game) and now I am starting to make highlights of each game. But some of the cameras have different frame rates and use different codecs. So now I am completely at a loss on how to get these working in linux. I would be ok with a GUI or some other video editing software if that is what it would take.

I've been using wayland with intel 520 graphics and, for the most part, it works excellently. However, I noticed that any hardware accelerated 1080p video playback (VLC,MPV etc) causes stuttering, not just in the video, but on the entire desktop (for instance, pressing super to see programs side by side with be stuttery).
I also noticed that, unlike with XORG, when video is playing played, the gr ...
I have used to mkvtoolnix functionality "mkvmerge" to play a sound file over a video that I made:
$ mkvmerge -o outFile.mkv -A vokoscreen-2021-11-20_21-51- bensound-popdance.mp3
This makes a new video with the sound of the sounf file playing over the video. Just like I want.
The problem is that the sound file is much longer than my video. What then happens is that the video just replays until the soundf ...

I'm fairly new to writing bash scripts. I wrote a script with the goal of fixing HEVC encoded MP4 files that are missing the ctts atom. It is based on this script from a Plex forum user. The script accomplishes what I am trying to do, but requires manually checking every file and running it against the script. I have over 450 movies in my library and I want to be able to run the script once and not ha ...
I use Ubuntu-Studio 20.04.3 LTS inside two desktop computers and one laptop computer.
That laptop is a HP 250 G5 device, which we can consider as an old computer.

I tested it with the same video, same resolution, same format file, but 29.97 fps and 50 fps. The 29.97 fps version is played "sat ...

Google Chrome can play local videos (which is useful, because it's safer than regular video players due to the sandboxing it uses).
However, it doesn't have any keyboard bindings except space
for "pause". Is there any way to configure skip-forward and skip-back keys without installing some extension published by an unfamiliar third party)?

I am using Ubuntu 18.04. Recently, almost for one month, every time I go to YouTube, Google Chrome consumes one full vCPU 100%, which causes my laptop's fans to start spinning as fast as they can. This happens only when I go to YouTube, even if I just go to youtube.com
and do not play any video.
