ByteScout Image To Video SDK – VBScript – Double Speed

multiple.vbs

' You can speed up the conversion using the following technique:
' 1) Generate video parts in parallel threads;
' 2) Combine these parts into final video.
' Let us say you have 20 slides.
' Then you can run a thread to convert 1-10 slides and another one to convert 11-20 slides.
' Finally combine these parts into a single one using .JoinWMVFiles(part1, part2, output) 
' or .JoingAVIFiles(part1, part2, output) functions.
