In my preview, I definitely see the trembling when the text zooms in, but the scrolling text looks fine. Also, for some reason, your produced clip is only 15fps, and any motion would look jumpy!

The trembling is caused by PD having to force the every pixel of your text (edge, border, shadow) into specific screen pixels, and that ends up causing a little distortion each time the zoom level changes.

For example, the ideal HD location for a specific text pixel might be at 803.64 x 601.38, but PD will have to place it at 804 x 601, even if that's in the same location as the previous frame, or worse, offset by pixel 1 vertically and 2 horizontally from the preceding frame. Each frame will look correct by itself, but when seen as part of a video sequence, the trembling is very obvious.

Try this workaround: I produced your original project to 4K, and that gives PD 4x more room to place each pixel. When I play the produced clip in VLC on an HD monitor, the trembling is hardly noticeable. Download the clip here.

I also imported that 4K version and produced it to HD in PD. Again, the text is very smooth because PD is simply encoding the existing video, not creating new content that has to fit in a specific set of pixels. HD version is here.

Optodata Thank you very much for your fast and competent support.
I always produce the texts in FullHD, I already did in 4K but it takes a lot of time and I still notice some tremor, curious that in PD14 it is perfect, unfortunately PD17v365 projects do not open in PD14, as I did until PD16.
I'm downloading your videos to see how it went.
I did this test at 15 FPS to overstate the error, and reduce the file.
But even with 120 FPS I still have a little bit.
Tests with border, shadow changes little here.
Some fonts have worked better but not perfect as I see in another application.

I just saw your video really better than here.
Do not see the 4K black screen shows
The one that has zoom still has little bit of just shaking what rolls is very good.
I'll make your suggestion, now HA is active halves the render time.

You can't import newer projects, but you can share titles by using Save As from the Title Designer in PD17, and then copying the newest Title_xxx folder from \Documents\CyberLink\PowerDirector\17.0\MyTitles to \Documents\CyberLink\PowerDirector\14.0\MyTitles. If there are a different number of titles in the 2 folders, rename the new folder to be the next one in sequence for PD14.

After importing the title, I see the same trembling in PD14. In fact, in my tests, the trembling is even more noticeable than with PD17. Look at the produced 4K version

I don't think more memory will do anything, especially with titles. 8GB is plenty!

Optodata Thanks for your interest, it always helps.
I checked your PD14 video, it's worse.
Here is little better see comparative here

Your Google Drive folder requires permission to download, so I requested that through Google. You can also change the permissions so that anyone can access/download it, but you'll probably need to post a new link.

Yes, I can see it now. I agree that the your PD14 version looks much smoother than mine. Maybe you should quickly get all of your titles produced in PD17 now before the trembling comes back
