I've been working on a video for a longtime client and ran into two baffling issues.

Issue 1) When typing text into a title with a custom color, the original color is only retained for the lowest line and final characters. Each preceding character/line is darker than the following ones because for some reason, the green setting drops off for the first character as each new character is entered

Titles with various combinations of characters look like a mild rainbow from top to bottom even though all characters have the same color in Title Designer:

I used the Color Board color picker dropper to pull the exact RGB setting for the top and bottom characters in each title and have attached a full size image with the details. You can see the middle (green) RGB value has shifted down from 168 to 128 over the course of 56 characters in 8 lines. In the Title Designer, all characters are set to 90, 168, 231 yet they show a clear gradient on the timeline which is also seen in the produced clip.

Issue 2) SVRT doesn't work correctly with specific profiles, including a custom MKV.

To reproduce the issue, I made an MKV version of 2 sample skateboard clips and produced it with NVENC. It plays normally, but when I add a short clip from the third skateboard clip in front and produce with SVRT, the result is garbage after the cut. Here's what VLC shows 4 seconds in:

I don't know if this is related to SVRT issues that occurred with PD18, but it's unusable here and now.

I've packed both test projects and also added the custom profile.ini and a sample of the bad SVRT produced clip in this OneDrive folder.

I've also reported the issue to CL on ticket #CS002252057 and I'll post back when they respond.

Hi optodata
I tested it here and I have the same problem, text (titles) is in full screen gradient.
SVRT did the same as yours, but if I render each video separately, it works correctly.
The difference I noticed
1st video has 29.97 fps (MP4)
2nd video has 30 fps (MKV)
Check if this is it. XEON-E5-2680 v4 / Mem. 16GB DDR4

Thanks very much for confirming both issues.

I hadn't thought about the clips having different frame rates, and like you I can produce each one with SVRT but the problem occurs when they're both produced to the custom MKV profile. SVRT works properly if I produce the timeline to the default AVC 1920 x 1080/30p (16 Mbps) profile.

I also tried producing the first clip to the same custom MKV format and then replaced the original clip with the new version, but SVRT still gave me a bad output even though both clips were identical. I need this format to meet my client's streaming requirements, and maybe tech support can suggest a settings change as a quick workaround.

Hi optodata
I did another test, now I created a profile from yours (test clip MKV) (I used profile Analyzer)
I produced Skateboard 03 (2 times) MKV
Replaces your test clip with the new clip
Now SVRT works as it should

I haven't looked at the SVRT issue, but the title colours problem is definitely confirmed here.

When standard colours are selected, there doesn't appear to be a problem, but when a custom colour is set optodata's findings are true.

I made a test project in PDR17, with two lots of multi-track titles. The first used a standard colour - RGB: 0, 128, 255 & the second used a custom colour - RGB: 90, 168, 231

Timeline & video snapshots showed consistent (but not perfect) colour from top row to bottom & left to right.

But EEK! When I opened the same project in PDR19, the preview screen indicated the issue straight away. Timeline & video snapshots showed a significant difference from top to bottom. In my test, the bottom most rows were rendered accurately, but the topmost rows weren't!

Table below shows RGB values of colours in the produced file:

Here's the packed project, including the MP4 rendered in PDR17.

Thanks for these results. I tried the same thing, but as long as I have an original skateboard clip and the new MKV clip on the timeline, the produced file is still bad.

The Profile Analyzer came up with with the settings on the right, and differences from the original settings are shown in orange boxes. None seem that far off, so I'm wondersing why it works on your end:

Thanks for confirming that you see this issue too, Tony. I hadn't tried the standard colors, but since multiple lines are needed along with custom colors to see the problem, I'm not all that surprised that it went unnoticed until now.

Hi optodata, I compared your profile with mine, I found only 2 different details I don't know if this can influence.
As I did I just left your "Test clip" on the timeline, I did Profile Analyzer

Another question.
Recent produce a video to advance while waiting for the audio to insert, in the certainty that it would use SVRT to finish, 1.30hs fullhd 60P.
As I made improvements to the general audio, it happened that SVRT did not activate in practice, not even when I added the video file to replace it.
I had to relocate the pre-produced video, I think it forced PD to analyze the file, now SVRT worked as it should.

I see what you mean, with the sharp line and purple color in the middle, but I don't see that on my system.

I made a title like yours in PD14 with two custom colors and then opened the project in PD365 and they look the same:

I also tried creating a new title in PD365 but the gradient still looks normal, so I can't reproduce the problem here.

Hi optodata, thank you very much for checking.
I checked here, creating a new title and applying the degrade works.
I noticed the problem happens with titles saved in the library by PD18, only for those that have In Scroll Animation.
I realized before using a project created in PD18 and reopened in PD19.
Thankfully they are few and I will recreate them if I need to.

I attached a project with 1 title saved in the library and another created now the problem appeared in 2, how to understand this.

I downloaded your project and I see the same hard color edge in your text. Having the shadow and border turned on make it worse, but even when they are both turned off there are 3 color bands instead of a smooth gradient.

Then I tried deleting most of the words in the title, and the problem went away:

This is clearly the same issue where the more characters in the title, the farther the color strays from the settings.

In your full title, if you look at the last 2 words they look normal although you can start to see the effect in the first part of BAIRRO.

Hi optodata, thank you for checking.
The problem exists since PD16 instability in the movement of the text, to get around I always do it first in fullHD 60P, but now it is not viable, a 3 minute clip takes about 30 minutes to produce.

This new problem in changing the gradient color exists.
Now it is expected that the competent support Ciberlink will fix everything. XEON-E5-2680 v4 / Mem. 16GB DDR4

EDIT: The SVRT problem described in my OP is still not resolved now with PD365 19.1.2321.0 when using the Profile Analyzer and choosing the MKV SVRT profile. The colored text fix from the previous version is still working, however.
