Hello,

I am having troubles getting a file that is originally XDCAM HD422 to convert to a Prores HD apch
The source file shows in MediaInfo has having:

Code: Select all

Frame rate                  : 29.970 (30000/1001) FPS

And the "Prores AW/KS" encoder node has the option to do 29.97 fps, but the encoder errors out with:

Code: Select all

"Encoding: Unsupported frame rate 2997/100. Set -strict option to 'unofficial' or lower in order to allow it!."

Attached is the screenshot of the MediaInfo of the video part of the source file and the encoder node settings.

How can I get this file to encode?

Regards,
Lue

Hi Lue,

this should be very much independent of the source file, however i created such a source file (using a 3rdparty encoder because ffastrans cannot do it) and set the prores encoder just like in your image. With the result that everything worked fine except my target file shows framerate 29970/1000, not sure if thats a bug from mediainfo or it really is that way.
However, i was not able to get to the same error messate as you show, what ffastrans version are you using?
What also worked for me is instead of choosing the framerate from the dropdown in the processor, i used a populate vars processor and set %s_somevariable% to 30000/1001. Then i used %s_somevariable% as the framerate in the prores encoder. In this case, my output file showed exactly this framerate instead of 29970/1000.
