video-everyday VS ffmpeg-python

I battled with this a lot with https://github.com/umaar/video-everyday and still haven't found a better solution.

What I don't understand is, how can professional video editing tools trim accurately (and very quickly)? What are they doing differently to ffmpeg?

If do things the "fast way" with ffmpeg, the exported video has random black frames which I think is related to the keyframe issue you mention. If I do things the "slow way" (e.g. accurately) with ffmpeg, it takes a huge amount of time (at least with large 4k videos). But I don't understand how I can drop that same 4k video into Screenflow, trim 1 second out of it and export it in a matter of seconds.

Even given an option it can be difficult to find the corresponding documentation, if only because of the many different submodules and encoders and decoders and filters that have o-so-slightly different options. That said, I've just switched from pydub to ffmpeg-python (due to memory issues of the former[1]) and judging from the Jupiter notebook[2] it seems a much more intuitive method of constructing ffmpeg pipelines.

You might want to look into ffmpeg-python as well

This bug on github sounds like the same issue you have

take a look at https://github.com/kkroening/ffmpeg-python

The ffmpeg-python python package still makes use of the “future” python package (search for “past” in the code base). These should be removed and updated as necessary.

I've had a look through these examples, but I can't get the numpy conversion to work (I get broken pipe errors, but if any of you can get it working this solution would be ideal)

Your going to be wanting to enumerate all the files in a folder, shuffle them, and then use a library for splicing them together. A quick google search brought me to moviePy, which seems pretty solid. ffmpeg is the industry standard for programmatically working with video, but it's...complicated to say the least. Looks like there are some good python bindings for it, but it may be overkill for this project. I'm sure there are others out there too.

I've been using ffmpeg-python recently, and it will do a lot of the crazy complex transforms for you, and you can write sane python code vs. trying to deal with the crazy default ffmpeg syntax.

ffmpeg is the traditional Swiss Army knife for video stuff. there's a Python library out there. might not be appropriate in an embedded environment though, it's a bit of a beast.
