Blackmagic Forum

Hi, Im quite new to Fusion render node,

I prepared a comp script which is supposed to load an mp4 video file,
trim it, add some text over it, and lastly output the result as a new mp4 file.

But, when I run the script in the cmd of an Ubuntu server:

Code: Select all

sudo xvfb-run /opt/BlackmagicDesign/FusionRenderNode17/FusionRenderNode /srv/common/scripts/Pohorje_rogla_08.comp -render -verbose -quiet -clean -quit

I get the error, that the mp4 file cannot be loaded:

Code: Select all

all the file paths are correct, ...

Have you confirmed you can load the same mp4 file in Fusion Studio? Maybe it contains a codec that Fusion doesn't support.

Use mediainfo to show what codecs are used in the MP4 and post the information here.

Yes, I tried to load the same file in the Fusion studio 17, and it loads and renders,
but with Fusion render node I still get the error...

With Mediainfo, for the specific mp4 file, I get the following report:

Any idea about this?
(btw, the filles srek.mp4 and generic.mp4 are the same file, I just renamed it in-between)
