Are you a sorcerer @Tom Speirs ??

Just created a new video of a table I recently created a video from.

From 204 MB you drop it to 12 MB !
I checked some other large video's too, and recreate one of my largest file !

Just curious : What parameter makes it much smaller ?
Edit : compared the 2 strings with old and new PinballX version. Need to figure out what it all means 

new:
-c:v h264_nvenc -an -rc vbr_hq -qmin 0 -cq 19 -b:v 3600k -maxrate:v 6400k -pix_fmt yuv420p -f mp4 -movflags +faststart

old:
-c:v h264_nvenc -an -qp 21 -pix_fmt yuv420p -f mp4 -movflags +faststart

Thanks sorcerer !
My cab will run coming week 24h/d to create all new videos !

For me the quality is much worse. How to change the parameters?

I asume it is buildin, so not able to change it. 

[davidcd13]

How do you find the quality?

[davidcd13]

I deleted all my videos to re-encode them. I regret...

I didn't noticed a difference, but only checked remotely. Will check tomorrow on the cab with 4k resolution

For me, the image is very pixelated and a loss of detail

Upgrade to the latest version and try again. Please report back with your results.

I believe this is an old post buddy that was rectified elsewhere.
