Can you upload a 4:4:4 file to my ftp and tell me exactly the steps you did? I have only 4:2:2 streams.
Sure. Notice I am using the test version.
Yes, of course. That's the version I just accidentally deleted all the source code for before committing it. :wow:

Fortunately I do full system backups every day and cycle my backups through car -> closet > USB dock and I found the code in my car's glove compartment (glove box for you limey and aussie types).

People call me paranoid but it doesn't mean they're not out to get me.

I've been saved at least 5-10 times by backups over the years, both for OS and data. I cannot understand people that do not do backups. My niece doesn't bother even after I set her up with an external drive and Reflect. If her disk crashes she's going to lose 20 years of photos and other irreplaceable stuff. I guess she'll just say "Oh, well." On my last trip the external drive was gone. "Where's the drive?" "It's buried somewhere in the basement, I wanted to declutter the desk."
:facepalm:

Fixed in the new version linked in the MKV demux thread.

The modes edit box actually had nothing to do with it. It was a race between the error popup and the parser crashing on an unexpected value of profile_idc.

Could you make it cook my meals and clean the house? :D It does just about everything else :bravo:
Can you please refer me to an appropriate spec for the meals. And a sample meal would be helpful too. Regarding the cleaning, when I get time to do my own house, I can consider doing yours. I demolished my kitchen a year ago and I'm still thinking about ordering new cabinets, etc. Meanwhile I am living out of one small frying pan and a microwave. The pizza slice box's top and bottom make fine free paper plates, ensuring that I have pizza for lunch at least every other day. And what's pizza without beer? Life is good. 8-)

Speaking of meals, I finally gave up on McDonalds. Bad food and inaccurate order filling on the last 5 trips, and anyway, they no longer speak English and they try to force me to use some unhygienic touch screen kiosk. No way, Hose-A. Chick-Fil-A is my new morning spot. What's Dunkin' Donuts like for morning chow?

If you like donuts and so-so coffee its fine
And what's pizza without beer?
Not so good

What about this stuff? Looks pretty good to me. Let's see if they speak English and can give you what you ordered at least 80% of the time.

And some people think highly of DD coffee. I'll go tomorrow and post a review here.

Do not eat 7-11 food unless you want ptomaine poisoning.

We call a boot a trunk. Weird, I know, but so is boot.

Never got excited or interested in OpenCL. Maybe one day. Thanks for sharing the link.

Guys and gals, which of these would you like to see next?

* 10/12/16-bit support for my utility filters

* CUDA solution for HDR->SDR. I would probably implement Reinhard tone mapping.

* Something else (please specify).

HDR -> SDR... :D
You're talking about a specific tone maping, does it mean you've made tests with several and thought this one is "the best" ?

Are you interested (even if you're not doing this feature right now) in an 50GB HDR movie, and in a 25GB file of the exact same movie in SDR ? It seems also that it's (at least for now) a "rare" 4k HDR nits mastering, when actualy almost all HDR mastering are for now at 1k nits.
Or maybe in smaller parts ? But if you want the whole thing, i can provide. The interest of having the whole movie is the possibility to test on a wide variety of scenes.
But maybe you allready have this kind of stuff ?

first

since 4K movies come with a 1080p SDR version

second
* CUDA solution for HDR->SDR. I would probably implement Reinhard tone mapping.

but you choose, your software and your brain power
and thanks for continuing to improve DGTools

More seriously, i also agree with gonca on the part "you choose" if finaly one feature request is not more asked than another.
My request was more for curiosity to see what it gives, than a real immediate needs.

Also, i'm sorry, it seems i've badly asked my question.
You choose one method among severals for HDR -> SDR.
Would you share the reason why you choose it ? Unless you've already done that in one of the posts of this 20 pages thread ?

I tested with the available Vapoursynth solutions and liked Reinhard best. It is also easy to implement and has some good literature representation. I have to start with something; that does not rule out adding other methods later. As there is no current Avisynth solution it would be good to get something usable out there.

As I mentioned earlier I am an incremental rather than a big-bang kind of person.

OK, gonna work on high-bit depth support for the utility filters.

This, at least 16 bit, as AviSynth+ 16 bit chain is almost complete. 10 bit as a necessary evil as h265 uses it in Main10 profile.

CUDA solution for HDR->SDR and possibly different dithering types even for bit depth decrease (at least none, ordered and floyd or bayer.

- High quality resizing (neural or any other hw possible thing)
- Temporal denoising (+ spatial, already existing)
- Make everything work as mtmode 2 in AVS+ :)

:agree:

Note sure if this of any use or interest https://developers.google.com/media/vp9/hdr-encoding/
under the heading
Convert SDR to HDR with a look-up table (LUT)
Converting HDR to SDR requires the transcoder to understand how to map brightness levels and colors to the smaller BT.709 color space and non-HDR range of brightness. For best results, an LUT describing how to perform that mapping -- usually specific to the content -- can be used. Examples C and D show how to use a LUT. We used bt2020_to_bt709_example.cube https://storage.googleapis.com/media.we ... ample.cube

Note: The LUT above is provided as an example of how to use an LUT with FFMpeg and is not optimized for the content in the example. LUTs are nearly always optimized for specific content.

MT_NICE_FILTER will be better I think ;)
As I understood from explanations and filter examples, programmer must care about memory allocations at getframe requests, not at the filter constructor. Mt mode 2 will care about safe memory allocation if filter allocates memory in the constructor, but it allocate, say, 4 times more memory with Prefetch(4). Imagine my double CPUs Xeon 2665 server running with 32 threads, so Prefetch(32) will eat a lot of RAM.
