Hello,

I have the problem that the video output flickers in fine details. https://www.dropbox.com/scl/fi/ibsmko92 ... kj8og&dl=0
My goal is to project a video with a HD projector in a continuous loop.
With the animation tool of Pano2VR 7.0.6. I let the images render with these settings:
Resolution: 1920x1080
Frame rate: 6
Rendering: no oversampling
no Motion Blur
Format: JPEG, Quality: 90
I have tried several other settings, but they never changed anything. Framerate 60 seemed to bring the least flickering so far.

I noticed that the rendered images from one to the other show these differences in the details even as a still image. So the renderer is not generating the exact same content in each frame, and that's what's causing the flickering in the sequence.
I have put two still images here as an example:

How can I get Pano2VR to always generate the same details in the frames?
Or does the problem lie somewhere else?

P.S. In my panorama output I have no problem with this flickering in the details.

Thanks for any tips.
Many greetings

If you search jitter of details you will find some info mostly regarding a plugin called neat video which I know can atleast reduce these problems. This can happen if there is too much details for the videoresolution. Maybe you could try different zoom level on the problemareas or render at higher resolution and then scale down, possibly this could be smoothed out. There is no flicker or jitter in the panorame as that is 1 image (frame). I think this problem is from ffmpeg.exe algorithms when rendering the animation.

Hi Stephan,
Use 60 FPS and Motion Blur.
Also, use TIFF as the file type, this will render quicker than JPEG.
