Simple Screen Recorder by default uses mkv whereas Youtube and Odysee.com don’t support mkv.
GIMP and Krita save the updated image in some forgettable format and not jpg or png. It’s a pain in the Jazz converting these things and uploading it to reddit/imgur or sending it to friends who aren’t using Linux.
Most applications use .tax.gz or something for creating a compressed file , you can’t open those damn files on android.
I have experienced this incompatibility several times, but these are the ones I remember right now, I am pretty sure more avid users have encountered this thousands of times in different applications. I love Linux, but why can’t we use file extensions which are most supported? I mean, I checked, .zip is opensource, I could have understood if it wasn’t and we used some open source alternative, but this is creating resistance in linux usage which isn’t really needed. We don’t need the user experience to be bad and this makes it bad.
Also, you might say, “hey don’t be lazy, just click on jpg every time you save an image through gimp” or “just make mp4 the default in simplescreenrecorder”, but this adds up pretty fast and you can’t ask every user to do unnecessary adjustments after they install applications. This has to stop!
Part of the Linux philosophy is open source (gnu et al) and open formsts.
If a file format is patented / proprietary / closed, then most open source tools are not going to generate that format by default.
Most do have options to export or convert, and when that option doesn’t exist, there are other tools that can do it.
One key thing to Linux (and MacOS) is understanding it doesn’t do everything for you so that you can tell it to do what you want, when you want.
Linux is free but it does take your time to get your workflow how you like it.
Mkv is just a container. It should be feasible to have things relatively wired so that when you make an mkv, with the click of a button (or automatically) convert to mp4 & tag & upload to YouTube.
It does require learning and mastery. Things have come a long way; Wi-Fi, for example, was ridiculous for a while.
