Is there any app or anyway for mac to search within a video's texts/transcription This might be a very niche thing, but I have a lot of local and downloaded videos on my Mac that I keep for educational purposes, and was wondering if it's possible to search through the transcriptions/speech within the video.
I know searching in finder allows the ability to search within text documents and file contents, I'm looking for something similar for videos.
I'm willing to manually attach the transcriptions myself to every video if that's required, since there are many apps that can do that. But the ability to search my entire Mac, like in finder, for a certain phrase and see which videos contain those search results would be extremely useful.
The closest thing available right now natively on macOS is to just paste as much of the transcript inside the comments section of the video's 'get info'. Doing this allows searching in finder and getting the video in the search results but there is character count limit so it's very limiting.
If the mp4 file has a subtitle track, you could extract the text to a .srt file using mp4box (more info can be found at How to extract subtitles from MP4 and MKV movies. Of course, you would need to do this for every file you have then search within those .srt files.
