I'm doing all this on Linux, and if I put a space either side of the colon, or any other regular character, including another colon, in the -o I get a unicode full-width colon in the filename by the look of it - but not if it's flanked by %H and co directly... 🤷

Seems like that might be a bug... 🫤

Which for Linux isn't strictly necessary.

see #9591 for that

duration is a numeric value (seconds) that can be interpreted by Python as a represenation of time and therefore formatted with a string template. duration_string has already been formatted with a string template. If duration_string is present in the metadata, then duration will be too, so why not just use duration?

[DavidPesticcio]

Okay, so I've just gone through what I thought I had already done earlier and see that applying >%H:%M:%S to duration_string is indeed wrong and only works as I need for duration

My confusion was that while duration_string contains colons, I need it zero padded, which I presume is not an option, and certainly not possible by applying a format.

Using %(duration>%H:%M:%S)s is giving the desired zero padded output.

Although, while investigating with --print it all looks fine, but as soon as I use -o for constructing the filename, and use --print to show me the result, I get underscore _ instead of a colon : in the filename - for the same formatting. 🫤

Here's a stripped down version of my yt-dlp options that highlights what I mean.

Is this expected behaviour? Or am I going crazy! 😄

On Windows, filenames cannot contain :, so yt-dlp sanitizes the filename by converting : to _. You could use a unicode full-width colon, e.g. "%(duration>%H：%M：%S)s"

[DavidPesticcio]

Additionally, as a workaround to get the desired format, I am using the following -o template to get a normal colon in the filename. Please don't break that, that's exactly what I need/want... 😄 lol

"[%(duration>%H)s:%(duration>%M)s:%(duration>%S)s]"

So it seems like the issue is isolated to whatever is used to parse %() sections.

Any presence of a colon elsewhere, for me, like the "%(title)", does seem to get converted to a unicode full-width colon. Which for Linux isn't strictly necessary.
