Hey, I was so frustrated and wanted to write a post asking for help with flickering and unsharp text in New Blue Titler Pro 5. But I figured it out so instead I write to explain what the problem was, and how to solve it, in case anyone else encounter the same issue.
It was a VP15 project and some, but not all, title texts were jittery and sometimes very blurry after rendering the video. I tried to rerender after rebooting the PC first, after switching the Dynamic Ram Preview on and off, after switching GPU acceleration on and off, but nothing helped. I opened the project in VP16 doing the same experiments in case it would handle the graphics better, but to no avail.
Then, after reading through NB Titler help I bumped into the cache settings. The help document said nothing about my issue but I learned that you can go into a NB title and in the menu select Title/Cache actions and then Re-cache this title. This made the trick! Then I saw you can also select Re-cache all titles. This fixed all titles at once and the project was rendered out with all titles and texts completely stable and sharp. Voila!
Now the videos are delivered to my client and I don't have to be embarrased about poor quality.
