- FilmCraft is an open-source video editing program with a panel layout and keyboard shortcuts similar to Adobe Premiere Pro. The original says it runs directly on macOS, Windows, and Linux, and also runs in web browsers via WebAssembly.
- The original says the H.264, HEVC, ProRes, and AAC codecs were implemented in-house based on public specifications. However, decoding of MP3, FLAC, ALAC, and Vorbis currently uses the external library symphonia, and it is stated that this will be replaced with an in-house implementation later.
- The README states that the H.264 decoder reaches 500~600fps at 1080p, and HEVC about 225fps. This is the development team's claim, and the measurement equipment and conditions are not given in the original.
- The development team says it checked decoding results against ffmpeg frame by frame. This verification method is as the development team described it; the original contains no independent verification results.
The part that bothers me most is that HEVC can be imported but not exported yet. The workflow I was used to in Premiere could break here, so I first want to think through which format I should export my footage in. The figure of about 225fps is a number the dev team wrote in the README, so I want to measure it myself on an actual laptop to see how it really performs.
