Additional comments

Hi,
Github issues are mostly for a well defined bug reports and not for seeking a help.
It is not that good idea to report a bug if you don't have reasonable experience to know what is a normal behavior.

Please use: discord server for more active help. Github also has a discussion tab, if you don't use discord.

Analysis:

• Terminal output is nominal, so this is not a installation problem.
• Output video file is created and should be there if you try to open it manually: '/home/dobrikg/RL/media/videos/main/480p15/CreateCircle.mp4'
• Only possible bug could be that -p flag fails to open the file at end, but there still is equal oportunity that this is limited/caused by OS. Current code does let file open subprocess fail silently with linux systems.

[HekpoMaH]

Thank you for the swift reply and analysis! I will check the server.

Being a meme lord, please accept this meme as gratitude:

[OliverStrait]

As an Teacher lord I accept your teaching.
But the thing is, where this meme is totally failing is that it is equally bad to go from "Everything is bad" to "everything is a good question". It feel cozy to have mother to pet your head, but nobody in interenet is someones special server, aka. MOM/CHATGPT.

Fairness is only way to really broke the cycle:

Let say, if you individually may see one shop cleark and remember the face and persona.
Are you angry if clerk does not remember you in next time?
The thing is, shop clerk sees many hundreds/thousand faces during a day, you are only one of them.

This is a speciality disparity.
This is elves-human disparity, teens-adult disparity.
Thousands years experience vs. everything is a new and a special event.

Here, there is over 400 issues, in today there is one more that is more of help request or lacking of basic computer skills, etc.
I have no Idea what is it because I cannot replicate the problem and OP-has no words/knowledge to explain the problem.

There is atleast 5 automatic report/Ai-automatic code slops dumbing in a corner.
Are you willing to go and resolve one of those?

This should be a project managment platform, but everyone are breaking one window while coming in, until every owl, cricket, wind and snow is coming in from every hole in the wall.

Until it is a wasteland of zombies wanting a special donation of brains. And it is reasonable to assume those brains will eventually left the building.
Or there is mighty tall walls and nobody new have any change to get in because every stranger is assumed to be a zombie....

As a teacher to teacher...

Github issues are mostly for a well defined bug reports and not for seeking a help.
It is not that good idea to report a bug if you don't have reasonable experience to know what is a normal behavior.

Should have been as simple as "seek help in XYZ", and should not have assumed my experience. If you were shop clerk I'd be speaking to your manager

As a meme lord...

[OliverStrait]

Should have been as simple as "seek help in XYZ", and should not have assumed my experience

I see, that is the annoying stinger in the butt. There was oportunity to not sit on that chair, because that really was not a named seat.

I realize my sharpness and thats why, I was so inspired by the first meme. It sparked connections in my mind why these systems and patterns are created in first place. And why seems like "seek help in XYZ" does not really cut it.
Because there is no ballance in the world scale.
Please is easy, solution will took energy.
Even to write "seek help in XYZ" will took energy...

I am not making that much of assumptions about peoples experiences, only based of what peoples write or not. If you have some hidden system knowledge, it was not really clearly stated in your message.
There could have been: 'I opened video files. Render was okay, but some reason video does not open as stated in documentation" Without something like that, I must read that you don't know what files and folders are because there is ton of those in console output.
My personal weaknes clearly still is that i react more strongly to mixed signal messages those are one marker of manipulators.

This is free work in here. Quality of pr/issue is about how much OP can trade knowledge so it does not seem parasitic. (parasite took energy and does not give back, mutualism is a trade of energy to other kind of energy, martytr will give all of his energy).

TL:DR aka. Possible solution / lead

When I googled the program that is called to open the rendered videos in linux systems: xdg-open. Results stated that in Ubuntu distors xdg-utils may not be installed. Re-/installing the packet may fix this.

Reports about faulty behaviour are generally welcome; in an ideal world we would be better at quickly converting issues that should rather be discussions into such -- unfortunately, we don't have so many active maintainers here.

In any case, I think it is best for everyone involved to stop this discussion here.
