The Data Analysis & Visualization Services of the Swiss National Supercomputing Centre (CSCS) helps the Swiss research community to present and visually explore the results of their studies. One of the services most requested is the production of movies from simulation results, especially from Molecular Dynamics. The computation platform is normally Linux, but the platform on which the movies are viewed is mostly Windows.
Those requirements made me explore various options, and mencoder application has been the best one found. So I started various test to find the best parameters and setup for our needs.
Here is an example of the images involved. Unfortunately the full set of images cannot be made available because the research results have not yet been published.
The images have a lot of sharp edges that move and disappear.
To create movies compatible with the PC Windows platform we are forced to use the Microsoft MPEG4 V2 codec that is present on every Windows machine. Instead the better MPEG4 codec requires the installation of the DivX codec (from www.divx.com).
Here you find:
Pass 2:labels means that mencoder crashed.
From the testing the following set of parameters seem the best for this particular set of frames:
No test has been performed yet. For now the following set of parameters has been acritically used:
I have found interesting also the following set of parameters:
