I always wanted a markdown-like video editor. I want to chop up my videos and make notes about what is in them. Text based document would be so much easier for this than big clunky Premiere.

This would be particularly useful for speeches or presentations where the content is the important part and the visuals don't change much (or wouldn't create jarring cuts when just editing based on the transcript).

Any thought on providing an option to make a super cut that produces a desired output? Ie `videogrep --input *.mp4 --produce "I am a robot"` and will find all the pieces it needs to produce the desired output?

Yes that’s possible, but the results are usually not so great!

I guess there would need to be an intermediate step. Videogrep helps to surface useful ngrams and there would still be a manual/creative step to stitch them together in a way that works.

Does it depend on the source material though? I think I'm happy with scattered tone and pitch if it comes out funny

This needs a function where you can give it a string and it goes and finds the longest matches from the database then builds a video that says what the string says.

Also it would be fun if it output a kdenlive project file, so you could easily tweak the boundaries or clip orders.

Have you seen https://www.descript.com/ it transcribes video and allows you to edit the transcript. Those edits to the transcript are reflected in the video. You can even train it to voices if you have enough content.

Yes it definitely depends on the source material… I’ll see about adding it in.

This is an useful tool for OSINT.

Amazing! Love it so much. My brain was running wild with possibilities (like having an autocomplete from the corpus, live audio only previews, and the above)

I didn't realise there was a github! You should add a link to your tutorial

https://github.com/antiboredom/videogrep

If I have the time I'll see how I go dipping my toes in the code.

Are you talking about EDLs? https://en.wikipedia.org/wiki/Edit_decision_list

I mean you can always write an EDL. The issue with most filmic material however is that moving pictures have their own internal timing, movments, directional changes and so on. Ignoring the content of shots is something that you might do with long shots of talking heads, but literally everything else won't let you get away with it in my experience.
