<div dir="ltr">Hi Tom,<div><br></div><div>Glad I could be of assistance.</div><div><br></div><div>Unfortunately, I am no GES expert.

For example this upcoming pipeline forces videoconvert to convert from I420 to I420_10LE as well as rescale the default resolution coming out of videotestsrc.<br>gst-launch-1.0 videotestsrc ! videoconvert ! video/x-raw,format=I420_10LE,width=1280,height=720 ! fakesink<br></div><div><br></div><div>I think the `format=I420_10LE` might be needed in your GES launch line to force the pixel format.

Any help would be very appreciated - I'm on the last day of a later deadline (first one missed) and the output file is incrediby low-quality at the moment.<br>
