The next official release still has to wait a little for now, but if you would like to try out the new feature urgently, send a message through the contact form.

Can you release an updated MagicYUV with V410 support included? I'm attempting to use VirtualDub2 with the Magewell Pro Capture HDMI 4K Plus LT to capture HDR10 video, but according to Magewell's site, the card only supports V410 and Y410 10-bit formats unless you use the Magewell Capture SDK for DirectKS which I don't know how to do.

It's finally done, sent an email.

Excuse the delay, I was out during the holidays.

Yes, it's on the list, I'll get it done this week so you can try it out.

Do you think it will be possible to have in the near future the v410 support . It would be amazing for hobbyists like me. Also as VDFM Dev is implementing a most broad support for 8/10 bit new formats there is more added value for both parts as each enforce the other .If done it would deserve at least a new release candidate 3 with v308 / v408 and v410 additional support considering that p210 and v210 have already been added.

Hi,

I'm terribly sorry for dropping the ball on you here, unfortunately I had my hands full with various issues. My apologies.

v410 support is really not hard to do, I just couldn't find the time to do it just yet. I'll get to it now, and it'll be done hopefully in a few days (or less).

The way it'll be released is in a beta most probably, as it's a new feature it can't make it into 2.0. So I'll either make a private build for you to test, or simply make a beta.

Will get back to you soon, and thanks for your patience!

EDIT:

Regarding dithering: That's what I expected. FFV1 is imported through VFW, and VFW has no standardized support for deep color (at least, Adobe does not implement any), so most likely the ffdshow or whatever VFW codec that decodes FFV1 does the dithering I assume. You can test this by somehow preventing the ffdshow decoder to dither, in which case Premiere will error out when opening.

h264/x264 on the other hand is decoded internally by Premiere, so it can interpret 10-bit correctly. As MagicYUV never converts downwards (from 10-bit to 8-bit for example), the dithering issue never happens, but as Adobe doesn't support any 10-bit+ formats through VFW it basically cannot open MagicYUV 10bit+ video at all.

There are some developments in this regard though, namely discussions with NLE makers regarding 10bit+ format support through standard codec interfaces (like VFW) are on the way, but nothing concrete has materialised yet...

To test if a FFV1 10 bit clip will be dithered when imported in Premiere CS6 I tried a Spears_Munsil_Quantization 2160p 10 bit clip test with patterns in 8 and 10 bit and converted it to FFV1 4:4:4 10 bit and to x264 YUV 4:4:4 10 bit lossless.

After importing the FFV1 clip it seems the quantization artifacts are visible in both half’s of the clip the 8 and 10 bit so it seems to prove that 10 bit FFV1 does indeed get dithered when imported into Premiere.

However the x264 10 bit lossless clip after being imported in premiere does not seem to have been dithered as the quantization artifacts are visible only on the 8bit half but not on the 10 bit half.

Related to v410 magicyuv support do you have any good news such as a beta or a rc3 already with v410 support. I am eager to test such a version if it does exist.

BTW if you get to test FFV1 10-bit with Premiere I'd be glad to hear the results!
