ffmpeg works really well for this. I have also been making time-lapse movies for over a decade, starting with using just Quicktime Pro 7 to combine the images into movies. Later using various other tools. Now I also use ffmpeg, and want to keep track of exactly how each movie is put together so looked for a way to script each movie. Now I use ffmpeg-python (not a lot of recent updates, but just works) to steer ffmpeg, with my own time-lapse specific Python package https://pypi.org/project/time-lapse/ to assemble the movies, and for each movie I have a single script which describes which frames are part of it and how they are combined into a movie; https://github.com/153957/time-lapse-scripts
I am quite happy with the setup, making it easy to recreate movies in the future from source, but at higher resolutions or different codecs.
Similarly I recently switched the other way. I recommend Lightroom over Capture One. The subscription is a slight downside, but Capture One is similarly expensive if you want to keep up with the latest version, I know you don't have to, but if you do it is expensive.
Moreover Capture One is missing some features which Lightroom has: The ability to filter collections based on their name. A shortcut for 'increase/decrease rating'. Filter photos for 'x stars and higher'. Show all images in a folder, including those in subalbums/subfolders. Being able to mark photos with a 'Reject' flag/rating (and easily hiding, not removing, those).
For a project where I worked on we offered streaming TSV responses and always finished the response with a last row containing a comment: `# Finished downloading.`. Since we also managed one of the client packages to access the endpoints, we check for that when the download is finished and raise an error if it is not there.
Great website which I used many times to check the precise species appearing in photos I made. Unfortunately the project seems to have stopped updating over 9 years ago (if the news page is a good indicator).
Recently I discovered ffmpeg-python [1], also a nice Python frontend to FFmpeg. One of its best features is being able to show nice graphs [2] showing where which filters are applied from in to output. And all FFmpeg filters can be used, it is a thin layer over FFmpeg, just much more readable.
