GLMixer performs real time graphical blending of several movie clips and of computer generated graphics.

Drop video files in the mixing workspace and place them in a circular area to change their opacity ; if you selects two videos, moving them together performs a fading transition. This principle generalizes to a large number of videos. Direct interaction with the video allows to be fast and reactive, and to move and deform them on screen.

The output of your operations is shown in the output window, typically displayed in full-screen on an external monitor or a projector. But the output can also be saved as a video file.

Control GLMixer through network using OpenSoundControl, and generate graphics with ShaderToy GLSL code.

User Reviews

  • I have been using GL Mixer for about 3 years now because it's interface gives me the best flexibility and fluidity I have had with any other software for displaying video (working as a VJ and programmer artist). I plan to keep using it and learning to use the various integration features it presents.
  • Thank you very much for the program distributed under a free open license!
  • I love it!
  • They really have done an excellent job with this application thus far and deserves a look if you are looking for a fluid live video mixing tool. Its stable and not a resource hog. I did a live stream performance using this and it was perfectly stable despite a heavy load running on the system which was streaming to twitch using OBS, TRaktor pro3 running, playing music, browser open and active for twitch admin and this running and there really wasnt a single hiccup. A few things i learned and was wishing like crazy for by end of hour 1. It would be AMAZING if the application had a way to adhoc record a movement patterns or have some presets that you could then just tap a hot key and trigger what ever is selected to move across the scene in that particular pattern. The fatigue of clicking dragging and whipping around scenes is real! Can be a ton of fun, but a very handy quality of life function like this would be so nice and make a live performance be a little more fluid. I feel like i pushed it pretty hard, i had 9 scenes and hundreds of clips or multiple types and sizes 99% of them some sort of motion graphic. The only time it struggled was when i had dropped a 4k mpeg in things got a tad choppy moving things around the interface but the output didnt glitch. Most if not all of that was due to the other 15 things my system was doing . One last thing Audio. I REALLY hope there is a plan to add some audio reactive abilities to chroma or hue effects or movement, something that could be applied to scenes and or a particular piece of content based on the audio from various audio sources. The various aspect is important all to often i see application that only listen to the "whats playing" channel, and for those of us that broadcast that is problematic (same goes for selecting screens for that matter, i run 4). Hope that stuff is helpful, i really enjoy it and will be pushing out new content tomorrow using it live. Keep up the fantastic work and frequent updates.
  • Ok, it seems to be the VJ software that I´m looking for... Let me see... INCREDIBLE!!!... I´m still amazed! THANKYOU Bruno, for your hard work, and to share it with us all!
