I have 25 short videos of family (~3 min each) that I would like to label with names of the various people. There can of course be many people on the screen at once, so I need to be able to add multiple labels (maybe with a box around the person and the name below, I'll have to see what it looks like). The labels also need to move with the person they're labeling, so AI object tracking would be nice, but that sounds complex/expensive so I can do that manually if need be.
This will make it easy to see who's who, but it would ruin the video for casual viewing. So I also want to be able to turn this layer/track off, just like subtitles.
This is inspired by Flickr's note feature, but that's just for static images.
So my questions are:
- Can I do this with a standard format like MP4? I'd like to avoid a proprietary format or website if possible, since this is for genealogy and will be archived. Who knows if "VideoAnnotations.io" will still be a thing in 30 years.
- HOW do I do this? I'm even having trouble figuring out how to search for what I want, since I'm not a video person and I don't really know the right terms to use. I'd appreciate a description of what this process is called, and then what tools I'd need to do it. Hopefully free tools, although I can get free access to iMovie, Pixelmator Pro and Adobe Creative Cloud. (I've never used Premire, but… there's a first time for everything.)
- It would be awesome if this could just be a text file I set next to the video, like an .srt, which would hold the various screen locations, strings and time stamps. I'd be willing to sacrifice a lot in the looks department to get something simple like this. But I don't know if it exists.
