  • (2021-05-25) Gabriel Angelo: Liked how it was convenient for videos without any subtitles, but problem is whenever you pause the video or a movie, it delays the subtitles and you need to keep on adjusting the speed of the subtitles so if maybe it can automatically change the speed of it to match the audio in the movie, that'll fix it, anyways thank you for making this amazing piece of work!

  • (2021-05-21) Richard Elgin: The Synchronisation control just doesn't work for me and it's needed as none of the subtitles i've tried are synced correctly. I'm mostly using it for stuff on Amazon Prime as they almost all lack subtitles. Am I the only one with this issue?

  • (2021-05-22, v:2.3.5) Niush Sitaula: Substital not working with Flowplayer embedded media.
    Substital detects video playing with "Flowplayer" (flowplayer.com), but when clicking on the video name from popup I get this.

  • (2021-05-21, v:2.3.5) Richard Elgin: Sync controls issue
    Advancing or delaying the sync control just doesn't seem to work correctly. It either just does nothing or changes the sync by a random amount of time.
  • (2021-05-18, v:2.3.5) Rachelle Phillips: RTVE Play+?
    I'm trying to use the extension on RTVE Play+, and weirdly, it seems to work just fine during the 8 second little opening logo video, but once the show itself starts playing, it stops working. Here's what I'm doing: I wait for the show to load in. I click the extension and choose the video. Then the app doesn't do anything, and the video either pauses or plays; that's it. Is this an issue with RTVE's webplayer?
  • (2021-05-18, v:2.3.5) Zach Van Dyke: Internal server error independent of Substital. The subtitles server is under maintenance
    I get the above error any time I try to use a subtitle file that the extension finds. Are the servers down? How long until I can use the extension?
  • (2021-05-17, v:2.3.5) Judah Bloodliine: Not Working. What's Going On?
    First the extension was working many times, a few months later, now it doesn't work. What's going on?

    Les serveurs sont il bien en maintenance ou bien c'est un bug ? Message: erreur interne de serveur indépendante de Substital. Le serveur de sous-titres est en cours de maintenance Réessayez dans quelques instants.
  • (2021-05-01, v:2.3.5) Finn Bunschek: Subtitle timing off on Amazon Prime, retrying a lot of times sometimes fixes it
    Only had this issue on Amazon Prime so far (and not Netflix), but when adding subtitles they are sometimes off by 15-20 seconds and it's not easy to adjust that. This also happens when I download the subtitles from Amazon directly and sync my subtitles to those or even use the downloaded (directly from Amazon) subtitles (subtitles have the correct timestamps, but Substital is not applying them correctly). Reloading a lot of times has fixed this so far, but it'd be great if you could look into this.

    Hello, you see I'm trying to use the extension on BiliBili, but when I select the video in the extension pop window, the upload and search options appear directly over the video and when I try to upload the subtitles I can't interact with the extension interface, the browser only recognizes the click over the video to play or pause it. Could you please tell me how can I upload my subtitles? or if there is another way to do it?
  • (2021-04-15, v:2.3.4) f8fortuna: Extension will not permanently delete from computer!

I went into my computer to delete the default data. I deleted what I believed was the temporary file. Subtitles still pop up! What is the name of the temporary extension file.

    Hi, Thanks a lot for this extension, it is very useful and appreciated. When I start a Netflix show, the extension correctly identifies it (series, season, episode), but I have to manually retype the show name (and season and episode) in the search text box. Would it be possible to do this automatically?

  • (2020-12-07, v:2.3.0) Baptiste Deneufbourg: Possibility to change screen space position?
    Hi, thank you for this great extension. I'm currently using it to learn languages with double subtitles (the original from the video + those I add with Substital). My problem is that Substital doesn't permit to change the screen position of the subtitles. I would like for exemple to be able to add an offset in vertical and horizontal (in pixels, or % relative) from the original position to position. More simply, being able to choose an alternate fixed position such as around the top of the screen would be good for this specific usage. Thank you for the great work, have a nice day.

This can be really useful for languages learning. Thank you.

    Hi. I am so sorry for bothering you but I couldn't find anywhere information on this problem: The icon is missing from chrome, but the extension is there when I browse to it. I cannot use it on netflix because there is not showing so I can click it. Do you have any idea why the extension is not showing on the chrome bar along with other extensions? Thank you
  • (2020-11-18, v:2.3.0) Dorota Gniedziejko: Not working in Chrome
    It worked perfectly, until yesterday - when I click on the icon, there's only blank white window instead of any video urls. I tried everything - resetting browser, clearing cache, uninstalling and reinstalling the extension - nothing helped. However, in the other browsers, like Firefox, there's no such problem.

    I appreciate the idea of dual subtitles for language learning. I'm trying to use this on Vlive, but once I load the .srt file, there's a green bar on the top of the video that says: 'Subtitles ready to play' But when I play the video there are no subtitles at all. Am I doing something wrong?
  • (2020-10-22, v:2.2.1) Zak Newcomb-Hall: Movable subtitles
    Hello, firstly I'd like to thank you for producing such an excellently functioning app! I'm currently using it to review my chinese with some videos and I was wondering if the extension could be extended such that I can move the subtitles so that they sit above the hardcoded english subs or even to the top of the screen. Many thanks
  • (2020-10-21, v:2.2.1) Steffi: Subtitles not loading
    Hello, since yesterday the extension seems to be not working for me properly. I am able to get into the subtitle selection section however, once i try to select the desired subtitle it says ''loading'' and just keeps me there for a moment and then throws me back to the subtitle selection without adding the subtitles. I also cannot X out of the pop up window.
  • (2020-09-24, v:2.2.1) cjog: When the video buffers, the subtitles keep on playing
    I don't know why but when my video is buffering, the subtitles keep on playing so when the video starts playing, it also has a delay now. I tried fixing it with the synchronization bar, but it's too much of a hassle when the video buffers again. Can you please fix this? Also, because of the player, I cannot choose my video quality through the original video player.
  • (2020-09-13, v:2.2.1) 陈泳金: Would you like to make this extension open source?
