hi @Gyan, what log do you need? The error I get is from the projector not from the `ffmpeg` command

Have you tried other profiles, or lowering the bit-rate? Also depending on your source material you may have to check your pixel format—use `-pix_fmt yuv420p` to make sure.

The log has details about the input as well as the various choices ffmpeg makes. This can help to diagnose.

@Gyan no matter what video I convert, I just don't understand from those specifications what type of codec / bitrate etc... I need to set to `ffmpeg` in order to make the projector read it, that's why I'm asking to more expert people about the topic
