That would be great. Thank you!
One other request I thought of recently...now that we
have a top-notch de-interl
Hi,
Current yuvkineco handles top-field-first 4:2:0 stream only.
I'm planning support 4:4:4, 4:2:2, 4:1:1 streams,
but thinking supporting bottom-field-first is rather difficult
and not needed if stream was preprocessed by
'yuvcorrect -T TOP_FORWARD -T INTERLACED_TOP_FIRST'
I'm planning yuvkineco

Where'd you get the 4:2:0 from? y4mscaler? If so then the conversion

Right - for 4:2:0. The "average from lines 1 and 2" and 'lines 3 and

The combination of the ADVC300 and y4mdenoise is quite the ticket

I've been experimenting with yuvkineco for a few
weeks. The only tool that's done more than yuvkineco
to increase my video quality is y4mdenoise! Stripping
out 20% of the frames in a 3-2-pulled-down stream, and
allowing the remaining frames to take up 20% more
space, has been a big win! And thos
