Amazing extension with great customization. One thing I would suggest is allowing for changing timestamps to use colons instead of underscores.

10/10 tool

The best YouTube Screenshot extension by far

A very useful and easy-to-use extension. One suggestion for improvement: Include the orientation and mirroring setting when creating a screenshot. Now these settings are ignored. Same goes btw for GIF Maker.

Default config is terrible with an annoyin shutter effect and a distracting flash. Configuring the downloads folder doesn't actually work, only allows the creation of subfolders. JUST PUT THE FUCKING FILES IN THE DOWNLOADS FOLDER.
Also breaks youtube hotkeys in fulscreen mode

Гифка рваная. Скриншот удалось сделать с 3 раза.

Screenshot function has great versatility and customisability.

Gif maker function could be better; restricts you to low frame rate and resolution. It's also kind of awkward to use, would be better if you could select the start and end frames before recording, instead of having to reclick the gif button at the right time.

Still a worthwhile extension to have, you can just disable the gif button in preferences menu.

Nice but I removed it until I found good addon to download 1080p video from screen record (or webmp capture or whatever) between two point of full video.

Thank you for this.
No bs, just works
A lot of options which are easily configurable.
I am just missing an option to change the save path.

Very customizable, recommended.

no option to add [{page title}] to the file names. only {ID}

Great addon.
I want to copy screenshot to clipboard by only left click.
Like "Screen Youtube" addon on chrome.

A really convenient add-on, everything works as you would expect.
My only gripe is that it only works on Youtube itself and not on embedded youtube videos that you can play on other websites.

Works exactly as advertised, highly useful and screenshots videos at their actual resolution unlike most other extensions, very customizable as well
Only thing I could call problem is that screenshots before first hour only have minutes and seconds in timestamp which messes with file order once video goes over an hour but it's really minor

Edit: Thanks for adding the save as .jpg option so quickly, excellent work!

Works great, though only seems to save in .png. An option to save in .jpg would be useful. Also, I'd like to be able to select a custom folder to save the screenshots.
