Take a movie playlist, remove studio logos and end credits, and re-encode to hevc, take the audio and re-encode ac3 at 640kbps
Playing with this stuff helps me think, keeps the old grey matter functioning

Perfect scenario for the adduced DGDecNV usage philosophy; there's no need for TS trimming.

I was looking for some strange and wicked material to test demuxing and I went thru a strange mkv with video encoded as 4:4:4 profile with 10 bit depth too.

DGIndexNV tells: "GPU decoder: CUVID currently supports only 4:2:0 chroma".

Is it a hardware or a software boundary?

NVDec (CUVID) does not support 4:4:4. Call it HW if you like because the VP engine is apparently limited.

If I try to set Decode_Modes=1,1,1,1 (in Settings) before exiting DGIndexNV, it hangs when dropping that file.

If I set 1,1,1,1, exit (so that it saves ini), run again and drop file, it complains with usual message then quits.

Posted: **Tue Mar 06, 2018 3:11 pm**

I can't duplicate that (with 4:2:2) and it shouldn't matter because the modes edit box does nothing until you exit. You should get an error popup when you drop the file and then when you dismiss the popup DGIndexNV should close.

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.

Based on the information I learned in the last couple of days
New Workflow

Open Main Movie mpls with DGIndexNV
Select audio track to demux
Set project properties, range - crop etc
Save project and demux audio
Re -encode
Remux
Simple
If I need subtitles I extract them and use the info in the dgi file to correct the timestamps (Don's idea of delays on subtitle led me to discover that if you manually enter a delay on subtitles in mkvmerge it will automatically correct all the timestamps for the subtitles) dgi project time start time (ms) would be the delay
Once again thanks for the help and information

Posted: **Tue Mar 06, 2018 3:41 pm**

Great to hear, gonca. Thanks for the update. Let me know if you think of anything DG tools can do to improve the process.

Posted: **Tue Mar 06, 2018 3:44 pm**

Well, since you asked
Could you make it cook my meals and clean the house?

It does just about everything else :bravo:

Yes, of course. That's the version I just accidentally deleted all the source code for before committing it.

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."

Great, thanks. Duplicated. Investigating...

Posted: **Tue Mar 06, 2018 4:40 pm**

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.

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.

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?

Bachelor life, isn't it great?
Dunkin' Donuts?
If you like donuts and so-so coffee its fine

And what's pizza without beer?

Not so good

I finally gave up on McDonalds

Smart move

Posted: **Tue Mar 06, 2018 5:59 pm**

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.

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).

Posted: **Mon Mar 12, 2018 3:03 pm**

HDR -> SDR...

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 ?

Not really, but thanks.

Posted: **Mon Mar 12, 2018 4:13 pm**

first

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

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
