It may be the format of the clip or it may be some settings you use.; and it may be the hardware or drivers or any combination?
On the 4K60 footage I have there is hardly any delay when changing such settings.
I have the preview set at full HD and I have enabled the creation of shadow files,which both help a bit with the speed of editing.

Maybe share some details, like your PD settings and information on the clip and on your PC (dxdiag file)?

PD is set to timeline 1080p/30. Media in is a mix of 1080p30, 4K30, and 4K60. The color adjustments are the same on all. There is a hesitancy of 1-3 sec as I adust and it doesn't seem to matter what the clip is. It's the same on 1080p. I have shadow files enabled and preview set to Full HD/Real Time/RGB.
I found an NVIDIA driver update and did that but no joy. I cut the clip to 4 sec but length/size made no difference. CPU usage never gets over 14% during the operation. When you say "hardly any delay" how much are you talking about? Did you compare to PD18? In 18 I estimate the corrections are applied in 300 - 500ms. In PD365 it's more like 2 sec.

Hardly delay is in terms of 100-500 ms (I have not measured that).
a quick look at your DXDiag file:

• the DirectX database is old, I use 1.3.5


• there may be a newer NVIDIA driver for you (do you have multiple GPU cards?)


• I see that the Cyberlink software including PD has crashed or aborted a number of times. (There is a newer version of PD available,than you use/reported).


• Maybe "play" a bit with the screen settings (why 125%?) and the PD preview settings (maybe HD is toohigh for your screen resolution). Etc.

No doubt others in the forum have more clever suggestions wrt your machine.

Thanks for your observations and taking the time to reply. I noticed the DXDIAG was from a few days ago when I reported Color Director ungodly slow. I have since updated PD and the NVIDIA drivers but it has had no effect on these problems. I reported the Color Director problem and received a cut & paste reply "it needs a fast computer" to run. I'm sure I'll get the same if I report this. PD18 was (and is) a stable, well crafted version. PD365 appears to me to be an onging beta test where many ambitious additions have bogged down the program in many unintended ways. I have a fairly fast computer now. I will be upgrading to the Ryzen 9 5950X this weekend which should put it about as fast as you can get under $10k or more. Davinci Resolve chews up 4K60 work effortlessly. I checked DirectX and MS claims v12 is the latest and windows update says I'm up to date. I ran a better test to quantify the issue. Take a small clip and open in a new project in PD 18, Open FIX and select Color Adjustment. use the up/down arrows next to the exposure adjustment and click up or down 10 times. (changing exposure from 100 to 90 as an example) In PD18 this completes in approx 7 sec. In PD365 it's approx 26 sec. How long does this take on your machine? (Iused my Iphone clock to time it)

In PD pref change your Display to YUV vs your current RGB and see if you have the same time to apply issue. Be sure to change, shutdown PD, relauch PD prior to testing.

Wow! It cut the time in half! Still twice PD18 but a real improvement. THANKS!!!!!!

In my opinion, I think they have introduced something strange with PD20 and possibly multi monitors. Friend of mine had issues too. He's running 3 multi monitors of various flavors. He went down to one monitor and these adjustments were instantaneous with PD20. Not sure if experience will repeat as I'm unsure what's creating the issue nor should one have to use a single monitor.

I really can't time my single monitor adjustment in PD20 for you, it's virtually instantaneous and any timing would just be error.

Very interesting! I run 3 monitors as well. I wonder if that relates to my issue with Color Director being DOGMEAT slow. I'll have to try it all with only one monitor enabled. Thanks again!!!!

No, I don't believe so. There you have encode slowness issue, not display.

Just be aware, since it appears you are doing fine color grading, YUV may have different display vs RGB.
