Deinterlace Quality

I posted this under the prompt to update thread but it was in the wrong place...

I am using V16B4 (032)
I am using a little clear time to get into V16 and has been good so far...
I posted at a similar time in V15 beta that i was revisiting home movies shot AVCHD. Back then I was looking for an answer to why some clips and not others would import. Back then DR15 just didn't even see them in the Windows directory despite them being right beside others that would be seen. I am delighted to say that they import now, no problem! However: I have spent a few days fixing a very patchy timeline import from PP XML. Very stable, everything good until just now when I noticed that the deinterlace in DR16 was a bit poor compared to the H264 guide out of PP so I went and found "Deinterlace Quality>" and set it to high. It crashed straight away. I booted and found that I had lost no work but Deinterlace was back to normal so I again set it to high. Crash. The next boot the Workspace had to be reset too: Primary Monitor. On the next boot I switched off Deinterlace Quality High. I predict the family will be none the wiser...

This is likely a hardware issue as i don't see others reporting.. what are your system details?

Sorry:
W10 - 1803
RTX 2080 TI
32 gig
i7 5930K ? Can’t be sure...not in front of it.

I have noticed the CPU tanking on 4K.

The timeline has about 3 hours of 1080i AVCHD.

I am having this issue now as well. My footage is 720x486 NTSC uncompressed. Wasn't having issues until I switched my Deinterlace Quality from Normal to Davinci Neural Engine. I even tried switching it to High. It would crash with that as well. However, it doesn't crash right away though. I can switch it, and then it will crash after playing for a few seconds. Sometimes it will crash at the same spot on the timeline as before. I would be surprised if this is is hardware issue given my computer's specs:

Windows 10
Ryzen 9 3900x
RTX 3090
64GB RAM

Did it crash while playing or while rendering? Neural deinterlacing is very demanding and I doubt it'll play smoothly on any hardware right now. Try a Render in place.

It crashed during playback and trying to render/deliver. I suppose I could try a render in place and see if that works.

Even for a 3090?

Even for a 3090, but crashing is not my experience on a humble laptop.
There must be some other issue,

Okay. I think I solved it. I had the Game Ready driver installed, but I installed the Creative Driver instead and it rendered on the first try. However, I do think the original render looks better. The one with the Davinci Neural has visible grid lines. Most notably in the blacks. Weird.

Try Video Enhancer AI by Topaz Labs then.

I honestly might have to give it a shot.

Can you post a sample of your original clip plus the issue you see to a cloud service?
While VEAI is a bit better than the neural deinterlacer, I have never seen grid structures from it.

Here are some screenshots that show the grid lines. It's most prominent in the black areas.

Could be deinterlacing artefacts if the camera was moving.
Can you post a short sample of the source? I'd try it with VEAI.

I use TMPGenc MW 7 to deinterlace, double frame rate ( to maintain temporal motion ) and at interpolation-high precision settings. Very fast and better than Resolve or even Topaz for some things.

Those examples also look like they were recorded without a good TBC for the tape playback.

It's possible. I currently don't have one.

Yeah, I can try and post a sample when I get home from work today.

The Neural Engine Deinterlacer works here in realtime on HD footage on my RTX A5000 which is a tad slower than the RTX 3090.

Sorry for the bad news, but deinterlacing in VEAI doesn't look any better.
I'm afraid that Ron Evans is right and you need a TBC for digitising.

We'll, I'm just glad to have an answer. Thanks guys! I appreciate it!
