Downloading subs only (from Freevee in this instance)

[pooksahib]

Hi. I've downloaded a comedy series from tubi but there are no subs. There ARE subs on Freevee which I've tried to get but with no luck. For ITVX and All4, I'd play the vid, enable subs, press F12 and filter for vtt but doing that on Freevee gives me nothing (pic attached).
Then I heard about Stream Detectors and so installed one on my Firefox. Again, nothing (as per pic).
Can anyone give me some pointers? Many thanks if so.

Amazon subtitle is ttml file so use subtitle edit to save srt file

Aha! For the benefit of others, play the Freevee vid with subs enabled (you have to be logged in to your Amazon account). Press F12, refresh the screen and filter for ttml. In the Method column choose a 'GET' entry (there may be more than one). Right-click it and select 'Open in new tab'. The new tab will be blank but in your usual download folder will be a .ttml2 file which can be opened with Subtitle Edit.

Thanks, iamghost.
