@avatar I tried you Sabrisse Scene with my 4K screen at 2160h x 3840w
It still had some stutter in it..
So I
resized all the images to 4K 2160 in height and cropped to 3000 width
7 images x 3000 = 21000 width.
but to make a smooth animation
I copied Image 1 and again added it to the end, so it's 8 images x 3000 = 24000
to allow for that last image to Not run off the screen, I added an extra 150 pixels of size.
the image is 2160 x 25500
Since it's going to be moving, using some Jpeg Compression won't affect it too much..
That One Big Image is Now Smaller in Size than a Single image from your Original file.
I adjusted the cameras Z depth, till I got the full image height to fit on screen.
then I changed the background to a calibrated image of Horizontal and Vertical Lines.
and made a screen capture.
I was able to find what the FOV was from that screen capture.
It came out to be 2160 x 3800
I made some calculations using this FOV and the Image size
Here's the results..
http://scenes.virtuastripper.net/Sabrisse-002.zipI put a bunch of comments in the .scn file to explain what I did.
It plays much smoother.
Cant post pic due to the nudity...
with a FOV width of 3800
the Image is Position at 3800 / 2 = 1900
8 frames of 3000 = 24000 with the last frame being a duplicate of the 1st
so really only 7 frames of 3000 advancement = 21000
by testing there was just a bit of jump when the animation starts again..
So I reduced it by 10 pixels to 20990
So that became the Animation Distance, needed.
The Math works to get you real close if you know all the Numbers..
FOV, Image Sizes
But if you Don't , then trial and Error with the numbers till it looks good...
edit: this pic wasn't too bad to censor.
