I opened a thread in the forum but I also post here to let people know about 2 interesting programs: 1- An interesting program for reviewing videos, VFX and animations: https://darbyjohnston.github.io/DJV/index.html Useful especially in the Pro environment. It has a license similar to Open Source but is not fully open. 2- Simpler but Open Source licensed: https://www.dneg.com/xstudio/
