Hi, so the subtitles need to be loaded, ideally after each video has loaded. Loading 3 sets of subtitles for example against one video will make it look like this.
This is the result of running the action 3 times. I just called each sub file “car subs” hence why it shows by the same name 3 times. You may need to try this out because when the video player changes sources, I’m unsure whether the subtitle tracks are cleared each time or if they persist. If they persist then you may want to remove the previous one. You can’t apply subs to a video which hasn’t yet loaded in the player.
Use the action within the loaded metadata event which will trigger after each video has been loaded. You can load multiple subtitles by running the action multiple times and they stack up in the player controls as shown above.
VTT files support a lot more in terms of styling and are generally a more advanced version than the SRT file types. That being said, I’m sure I’ve managed to load SRT files though. Best thing is that if you’re able to send me the URL to one of your videos and the associated SRT file for that video, then I can try loading the SRT file and debug where necessary.
I’m sure with a bit of playing around with the actions and timings, you can do what you need to.
