I'm telling you, there will be a streaming service that will deepfake ads into finished movies. Darth Vader will turn at the at the camera and say "No, I am your father... and you should buy the Elon Musk biography on audible dot com for free"
According to a site admin from that forum post (which is from April 2021--who knows where things stand now):
If you use the OpenSubtitles website manually, you will have advertisements on the web site, NOT inside the subtitles.
If you use some API-software to download subtitles (Plex, Kodi, BSPlayer or whatever), you are not using the web site, so you do NOT have these web advertisements. To compensate this, ads are being added on-the-fly to the subtitles itself.
Also, from a different admin
add few words from my side - it is good you are talking about ads. They not generating a lot of revenue, but on other side we have more VIP subscriptions because of it :) We have in ads something like "Become VIP member and Remove all ads..."
Also, the ads in subtitles are always inserted on "empty" space. It is never in middle of movie. What Roozel wrote - "I think placing those ads at the beginning and end is somewhat OK but not in the middle or at random points in the film" - should not happen, if yes, send me the subtitle.
If the subtitle is from tv series, there are dialogues from beginning usually. System is finding "quiet" place where ads would fit, and yes, this can be after 3 minutes of dialogue...
This is important to know, I hope now it is more clear about subtitle ads - why we are doing this, there is possibility to remove them and how system works.
so a scenario like in the screenshot isn't supposed to happen. I guess if you really wanted to see if it happens you could grab all the English subs via the API and just do a quick grep or what-have-you
“One does not simply walk into Mordor…” Boromir turns to the camera and continues, “…unlike this video’s sponsor - nordvpn! With the code ‘flame of the west’ you can simply walk your way into an 85% discount off the price of a full years subscription! Thanks nordvpn, and now back to the council of Elrond”
I occasionally see those types of ads in subs downloaded through the Plex UI, but usually it's in an intro or at the end. Haven't seen them in the middle of a dialogue yet.
Some of them try and sneak an ad at the start or end. It's rare though.
Most stuff now is mkv which has a good chance of including the subtitles straight from the Blu-ray or streaming service.
I tend to wait for at least a digital or physical release before downloading so I don't get a load of blurry crap with an ad for an Asian gambling site splattered across the middle of it.
