Why do my raster images look wavy when exported?

Post by eimber »

Hi everyone,

I'm new to Moho and have an exporting question:

Why do my animated raster images look wavy?
The original images are scaled for 1080 X 1920, 300 ppi.
I exported at H264.

What is the ppi for HD movies?
Is there another program better for exporting raster-based animations?

I attached an 11-second clip of the "heat wave" effect over the moving basket that makes the basket and lines appear wavy.
If possible, please view at full screen.

Thanks for your help in advance!

I watched it at 1080p fullscreen on an HD display....but I'm not seeing any problem.

This is called Moiré and happens because you have very thin lines, which in that default Vimeo player size are in the area of 1 px width and only 1 px apart. If you watch in full HD resolution, you will not see this.
