AppleTV Subtitles still Incorrect in SF 7001

DarkSkies

Episodes recorded on AppleTV have the wrong subtitles. The subtitles seem to be from a prior episode, and seem to start “midway” through the previous episode. This is repeatable and existed in version 7 and continues in version 7001. Before my latest attempt, I cleared temp/cache and logs and started with a fresh login to AppleTV and downloaded episode 6 of season 1 of Pluribus as HDR10+ 4K 5.1 audio.

Submitted Feedback through the app, attaching logs here in case anyone else finds something and/or wants to corroborate the issue.

Something funky is definitely going on, look at the sequence numbers inside the VTT (Pluribus S01E06/EN, and shouldn’t there be forced EN subs, I only get a regular captions file, luckily forced is a subset of that so not missing out), for example:-

DarkSkies for future reference, could you tag your posts with the appropriate module name so that it’s easier to find instead of a generic “Feedback & Support” tag like:-

Germania

I can’t confirm that, neither as a separate srt
nor like you as “Remux into file” in mp4.

Is it possible that you dl multiple epis at once?
(I added only the single epi to queue - like your log)

“Extract Original Format” has never worked for half of all providers.

But this has nothing to do with op, because he used Remux. As I wrote:

And extract to srt (other then vtt and used for remux) is fine for me.

Thanks for checking @Germania

Before trying again today, I completely wiped TEMP and LOGS and started by logging in to AppleTV, and I grabbed the episode with no other titles in the queue. (Sequence: close SF, confirm all processes closed, clear TEMP, clear LOGS, launch SF, open AppleTV, login, click Pluribus from home screen. Analysis commenced, I selected HDR+, max 4K resolution, and 5.1 audio, clicked Download Now.

My intent was to ensure there were no “leftovers” from any prior downloads, so if there were issues, it would be in a clean log and only based on this one download.

Based on today’s results, I just checked all episodes of The Last Frontier that I captured from from AppleTV a few days ago (version 7.0.0) and every one of them has the wrong subtitles.

Turns out another user is having this issue wth Apple and Pluribus, but in this case with Apple on Amazon: https://forum.dvdfab.cn/d/470235-subtitles-are-a-mess

So something is funky with AppleTV (but apparetnly not consistently funky)

Remove the attached pic, it’s included the user email…

I don’t think it’s a good idea for your email address to be visible.

Close SF, rename your cache - like here
start SF, enter your mail/pass and click on save:

then confirm “Trust”

Please note that you need relogin for all provider

Germania Det tænkte jeg ikke lige over, da jeg lagde dem op, men det vil jeg helt sikkert gøre en anden gang, og tak, det vil jeg prøve.

0xFeedBeef Thanks for drilling into the subtitle issue. It’s very bizarre… hope the dev team can sort it out.

(Note: I had originally selected the AppleTV tag but changed it when I added the log, thinking I needed to reference that. It would be great if we chould have moe than one user-supplied tag.)

Germania I wouldn’t be so certain- the way that SF works is that it assembles the captions file from sources, and only then either muxes that into mp4/mkv, converts that to srt (probably using ffmpeg), or simply moves the assembled file to the correct place under the correct name. So the vtt that I get is literally what SF assembles from Apple, where as what you get is an attempted fix by ffmpeg

0xFeedBeef I wouldn’t be so certain

“Remux Into File (SRT)” convert vtt to srt before remux

I tried remux and open result in SubTitle Edit:
The entire text and start times are identical with “Extract to SRT” ..
.. only the end times are sometimes (exact 3x) 300 ms earlier.

I have the same issue. Could this be an Apple issue?

0xFeedBeef

Germania convert vtt to srt

and the conversion is most likely done by ffmpeg, and I’d not be surprised if it tries to repair presentation times by re-ordering them property and ignoring vtt sequence numbers

It’s not really a “tag” per se, but more of a sub-forum selector:

Chameleon I doubt it- chances are they get linear captions and they apply them correctly… maybe SF is catching “recap” captions? I don’t know, never looked at episode manifests…

I’m not sure if this is related, but I am also having an issue with Apple subtitles, specifically forced subs. It is happening randomly on multiple TV series. An example is Home Before Dark S01E01. Selection window shows forced subs available so I selected both english subs and english forced subs. I have subs set to remux into file.
The file I got shows both text files are present (in mediainfo). When I play the file I don’t see any forced subs. So I checked in subtitle edit and its shows 4 entries, but they are very short and have no text. The first one is 1.085 seconds and the last three are .333 seconds. There are 5 more episodes in the series where this is also happening. Why would there be subtitles with no text?
I just tried again with 7002 and no change.
This doesn’t seem to affect how the file plays, it is just weird and I don’t know if it is related to other subtitle problems.

TheRaven Why would there be subtitles with no text?

I tried s01e01 with both English subtitles ..
.. once with “Extract to SRT” and once with “Remux into File”
and can confirm that the entries in forced en have no text
(en full begins with entry 4: “I am a reporter.”)

To verify this, I manually dl the original VTT
and received a VTT with 11 segments with only the header “WEBVTT”

So it’s not an SF issue - it’s the offer from AppleTV

btw: Otherwise, I only know empty lines from episodes with (undownloaded) flashbacks ..
..but that doesn’t make sense for s01e01.

sometimes ATV plays promo material for upcoming series and such, maybe it’s that?

Sounds entirely possible ..
.. but 11 segments for subs seems too much to me
