Issue with VS19 Ultimate White Balance

[Raouliii]

I noticed this on a project and investigated it with just a short, simple project using VS19 Ulimate.

One clip at 2.7K/30 from Osmo Action placed on timeline 4 times. Output to 1080/30. 1st of the clips has no FX, the 2nd the only FX adjustment applied is under the Color Tab, WB with the dropper tool, the 3rd WB applied with Auto, the 4th WB with a Temperature selected. No zooms/pans, etc. The output file indicates 1080p/30 with great down-resolution of the 1st clip but horrible, grainy, artifacty, conversion of the 2nd, 3rd and 4th clip. It seems that regardless of how I apply WB, it ruins the conversion from 2.7K to 1080.

Has anyone else noticed this issue? Could I be doing something wrong? Does VS20 do the same thing?

Here's a link to the output file:

I don't think 2020 will fix that ,you can try the trial, but some thing wrong here.

Has anyone else noticed this issue?

I've seen this in VS2018 and it seems to be dependent on the properties of the clip. In the end, I used another NLE on these problematic clips and then brought them back into VS.

Thanks for the responses.

I investigated further and found that applying the VS19, Color Tab, White Balance Auto, Pick Color or Temperature adjustments results in severe degradation of both 2.7K and 1080 source video when output as 1080.

A work around is to use the NewBlue ColorFast, ColorFix Plus or ColorFix Pro filters to apply white balance with the Pick White tool.

I would be interested to know if anyone has experienced results different from mine. If this issue is common, it's odd that it hasn't been brought up here before.

Thanks

Hi Raouliii

I have just ran a test using a short MTS 1080 video file
Applied white balance as your instructions
Using 2019 were disappointing, the same using 2020 were much better

I then rendered using 2019 but deselected and deleted my Smart Proxy files with much better results
So try removing Smart Proxy then render.

What I do see is a pause in playback at approx. 00:00:01:012 with video rendered using 2019, and at the moment I cannot explain that.

I have uploaded the 3 M2ts files to my one drive here, each file is approx. 40Mb

Post updated
in addition to deselecting Smart Proxies I also deselected Smart Render ( from the Share Panel) that seems to have cured the slight pause / plip in playback?

Thanks for the response and the test. It's interesting that you are finding a relationship between the smart proxy files and the poor white balance performance of the Color Tab.

Unfortunately, deleting and then regenerating the proxy files every time I render a new version of a project would be an unacceptable workaround for me.

As I posted, using the NewBlue ColorFast or ColorFix options for white balance is an easy fix for what appears to be a flaw in VS19.

Thanks again
