Hardware vs Software Transcoding

Can someone explain the difference between these to setting for the web player? Which setting would be better for my setup?

Hardware is default and there is no reason to switch to software unless you’re having issues.

Thanks. It seems that the lowest setting of 240 is not supported on hardware transcoding. But Software does support this. see the log:

You’re right, the 240p option does not work with the Hardware transcoder on the mac.

This has been fixed so that it is no longer possible to select 240p when using the Mac hardware transcoder.

Is ther a way to verify i am using hardware transcoding besides the GUI menu selection? I don’t see any mention in the DVD log to indicate.

It says “encoder=h264_videotoolbox” in the log
