[Paraview] [EXTERNAL] Regarding creating high quality small size animations

[Scott, W Alan]

As with most things in life, you have a balance.  Generally speaking, for better quality, you will need larger movies.  For smaller movies, you will have higher compression and poorer quality.  And of course, the smaller the screen size, the smaller the resultant movie.  So, you get to choose.

.png is an intermediate file format or storage that you will use.  I believe that when you make movies, the final file format (and movie size) is what will determine the movie size.

Regarding .png’s, they are lossless compression.  .jpg’s are lossy compression.  Png’s lose no quality, jpg’s lose quality.

Hi Scott

Thanks for your reply. Will PNG ensure the final movie size is small? Or is there something else that will determine the final size?

Save as a flipbook of .png’s.  Then, post process this into any type of move files (.avi etc).  Use a third party movie creating program, such as ffmpeg.  I think vlc may also do it, but have never done so.

Dear all

I am trying to export my animation, but want to keep the size small, and quality of the simulation good. How can I go about it?

I tried to directly save in the avi format, but the quality is bad and size is too large.
