   1 313 31,104 9.7 TypeScript

   The swiss army knife of lossless video/audio editing

   

   I recently found LosslessCut (https://github.com/mifi/lossless-cut) that is basically a GUI for ffmpeg, you can make simple edits without re-encoding the stream.

4. editly

   3 10 4,951 9.0 TypeScript

   Slick, declarative command line video editing & API

   

   I found https://github.com/mifi/editly to be an intuitive frontend for this type of task - I used it to create a montage of several clips and was able to easily adjust parameters around timestamps and such to get the montage perfect

5. time-lapse-scripts

   4 1 1 7.9 Python

   Repository of scripts to build specific time-lapse movies

   

   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

6. aichat

   5 32 6,681 9.6 Rust

   All-in-one LLM CLI tool featuring Shell Assistant, Chat-REPL, RAG, AI Tools & Agents, with access to OpenAI, Claude, Gemini, Ollama, Groq, and more.

   

   That way I can use any aichat backend as necessary, I actually have time to verify the output myself, and all the commands get saved to my history.

   The prompt that runs is the following: "Based on the following user description, generate a corresponding Fish shell command. Focus solely on interpreting the requirements and translating them into a single, executable Fish command. Ensure accuracy and relevance to the user's description. The output should be a valid Fish command that directly aligns with the user's intent, ready for execution in a command-line environment. Do not output anything except for the command. No code block, no English explanation, no newlines, and no start/end tags."
