[hellox9]

You know you can select content from a terminal window and post it in 'code'-tags and thus make the whole thing way better readable, right?

From the looks of it you should used quotes (ass="...") so that the parser knows this is one value and the backslashes are not there to escape something.

[hellox9]

ffmpeg -i C:\Users\User\Videos\Japan_Hour\Its_Lunchtime_1_temp.mp4 -vf ass="C:\Users\User\Videos\Japan_Hour\working\Its_Lunchtime_1_subtitle.ass" C:\Users\User\Videos\Japan_Hour\Its_Lunchtime_1.mp4

i tried with the quotes, still have the same error.

this is the first few lines of my subtitle .ass file

[Selur]

Okay, problem is that the path of the ass file needs to be properly escaped. (I hoped adding quotes would already help.)
Try:

ffmpeg -i C:\Users\User\Videos\Japan_Hour\Its_Lunchtime_1_temp.mp4 -vf "ass='C\:/Users/User/Videos/Japan_Hour/working/Its_Lunchtime_1_subtitle.ass'" C:\Users\User\Videos\Japan_Hour\Its_Lunchtime_1.mp4

what I did is:

• replace back- (\) with forward- (/) slashes (alternatively each back-slash could be escaped with another back-slash)
• put the path in ticks (')
• escape any special characters, here the colon (:), with a back-slash (\)
• put the ass parameter in quotes (")

here's another example:

ffmpeg -y -i "f:\TestClips&Co\test.avi" -filter_complex "ass='F\:\\TestClips\&Co\\files\\Subtitles\\test.ass'" e:\Output\test.mkv

where I escaped the back-slashes with back-slashes.

thanks man it works!!
Is there any favor i can do for u in return?

[hellox9]

also its a pain to burn the subtitles in for the videos, but windows media player cant seem to play the vtt file alongside the mp4, do u know how to fix that?

[Selur]

Don't use Windows Media Player, use MPC-HC, VLC, MPV, or any other common player.
No clue whether there is a way to get Windows Media Player to recognize vtt files.

basic conversion of vtt text to srt is also possible.
