On my Vu+ Duo 4K SE with OpenPli 9.1, I am used to recording movies and then removing the ads (Edidor Cut List, Movie Cut ...) and the margins before and after recording.
For a very long time, a brief black screen has been displayed a few seconds after the recording is resumed and later the audio is cut.
What could be the origin of this anomaly ?
How do I delete it ?
Thank you for any help.
