Ok, thanks. But my value of EDID and CVT CRV are different and when select CVT CRV, my screen blink.
Can I edit the timings equally?
Thanks

Not sure what you mean with "edit equally"? You can simply assign the EDID values, if that helps, you don't have to change them in any way.

Which column I should look for?

[madshi]

I'm not completely sure, you can also post the raw data here (ideally in a "code" block), then I can have a look myself.

Hmmmm... This might be a "bug" in madVR, I'll look into it. The EDID can be pretty hard to interpret correctly. Even Windows itself and the GPU drivers often have interpretation errors...

Hi, sorry if I use a PM, but I don't know if I can publicly post this video: *in PM* .
With that, my screen should change to 29.97Hz (which is supported, I just tested with another video), but it remains at 23.97Hz.
In case is any useful, I have: Win8.1, AMD A6-4455M, smooth motion off, D3D11 exclusive.
Thank you.

Edit: what report?

[madshi]

You should remove the link to the video. Ideally, post the report here, and send the link via PM (no need to do that now since you already did), that's the best solution.

I have recently been trying D3D11 decoding, however it seems that either I get alot of repeated frames the first few seconds OR a couple of dropped frames (lag-like) in the first few minutes of pretty much every file I play.
Anyway to troubleshoot it/log it/test it?

It didn't happen on DXVA2 (Copy-Back)

Edit: is this possibly memory or CPU related? or not at all?
Second Edit: on DXVA2 (Copy-Back) I had de-selected HW-Decoding for HD content and it also happens on HD content, on D3D11 I do use HW-Decoding for HD content.

Just for the record. I have found that obsolete Haali has similar problem with crop, but it crashes imediatelly.
https://www.matroska.org/technical/specs/index.html
There is, when you enter "crop" in search field some more information that would be possibly helpful to someone.
But I know that this problem has very very low priority.

So I guess if you achieve a 4 hour drop/repeat and it works without glitches, you could write the timings details down before you continue to optimize, as a safe fallback.

Thanks, I have achieved '1 frame drop every 1.45 day' and 100 compatibility. When I have more time again I see how far I can push it. Best wishes

Did not even consider watching HDR clips could cause that problem. But now that you have mentioned it, you might be onto something there. Again, I agree, sounds impossible.

Please could you specify which files you were testing? The file I have a problem with plays fine on one of Madshi's monitors, so more test files causing the issue might help him to reproduce it.

Thanks for taking the time to test.

The flashing not working on your non-HDR monitor might be related, hopefully if you solve this you'll solve the other issue.

What happens in HDR is that the last displayed frame is stuck, whether it's a black screen (first frame) or the last frame displayed in windowed mode if you go full screen > window > fullscreen.

So the flashing not working on your non-HDR monitor might indicate a similar problem, the last displayed frame stuck.

This is the only file causing such issue here, so if it's not representative of a wider bug it's safe to let it go, it might just be an issue with the file mastering.

However, the same file plays fine on the UB900 (that's how I've been using it until now) so it's not an issue with all players.

[mparade]

Is HDR data independent from the bit depth of the video (number of steps between each color)? Can be displayed correctly theoretically a 12-bit encoded HDR video which has the same HDR metadata as the source file which was 10 bit encoded?

Would appreciate any help.

I did not have a problem playing those files per se. Clips played fine in loop until a reboot resulted in OS partition corruption.

I just played these 3 files over and over from demo-uhd3d

The_World_in_HDR_in_4K_HDR10
Sony_4K_HDR_Camp
LG_Chess_HDR

Pretty standard clips for testing. I was on madvr 0.92.1.

I'll try to look at that. It shouldn't be as smooth as smooth motion, right?

Slightly offtopic but a quick note for anyone interested in HDR test patterns.
There is ongoing development of free HDR10 patterns set by video enthusiasts for other enthusiasts. Current version is here: https://yadi.sk/d/RPrX2C7l3HEjPq

There is no guide/readme or separate forum discussion topic for now but we've tried to keep file names self-explanatory.
Hope it could be useful!

I'm trying to download the file but I'm not sure it will succeed. Download has been running for a couple of hours now and I'm at maybe 25%. Maybe you could use a better upload site? FWIW, I've made good experiences with mediafire.

This is a somehwat confusing report. I'm not sure what to say. It's not clear to me how DXVA2 and D3D11 relate to each other, after your 2 edits, and I'm also not sure if the problem only occurs right at the start of the movie, or throughout the whole movie. One important thing to look at is which queues might go empty (or near empty) in the Ctrl+J OSD, in the moment when the frame drops occur.

Yes, it's independent.

It should be exactly as smooth as smooth motion, because all smooth motion does it simulate a monitor which has a refresh rate that perfectly matches your movie frame rate. Basically 71hz should look exactly like smooth motion, minus the minor blurring and ghosting that some users see (and some don't) when using smooth motion.

Nice!

[huhn]

can someone else test smoothmotion at 144 hz with a 23p source?

i see some really big issues on that screen right now and i don't know why.

[Asmodian]

I do this all the time. What issues do you have?
