Dome2rect v1.5.2

New in Dome2rect version 1.5 is a movie2imagesequence.bat script that makes it easy to extract image sequences from any .mp4 movies placed in the dome2rect input folder. Also added a script alphaextract.bat that extracts a transparent mask from footage and saves it into an RGB image file in the output folder. The encodemovie.bat script will re-encode a mp4/mov/mkv/avi movie file with ffmpeg into a compact mp4 movie to make it playback better on mobile/tablets/desktop systems. The imagesequence2movie.bat script will turn your image sequence into an mp4 movie using ffmpeg.
