Q & A

Q: vimix crashes on launch / does not launch

First, thanks for making sure you have the latest version. Under Linux, try with Flatpak or Snap.

A: Try to reset vimix settings by removing the config file:

Linux;

  rm -r ~/.config/vimix/

OSX;

1. "Go to folder" (shift+command+G) in OSX Finder

2. Enter (replace username by your own):

   /Users/[username]/Library/Application Support/vimix
   

3. Delete the content of the folder 'vimix'

Q: vimix fails playing a video or blocs at the end.

A: Switch to software decoding:

In the left panel properties of a video source, choose Software only for Decoding.

You can also disable all hardware acceleration in vimix Settings - System - Hardware en/decoding.

Q: Playing a video backward does not work (e.g. with loop mode set to 'Bounce')

A: Switch to software decoding (see above)

A: Try to re-encode your video:

  ffmpeg -i in.mp4 -force_key_frames "expr:gte(t,n_forced)" out.mp4

Running this on your input video will re-encode the video with more key-frames, and this should make the backward playing and bouncing work without problem.

Q: There are warning or error message for Wayland under Linux

A: Do not use Wayland, set your desktop to run X11

Although progressively replacing X11, Wayland does not yet offer all features needed. Typically, hardware acceleration of nvidia GPU does not seem effective (low FPS) and placement of windows is not allowed.
