hello,
is it possible to export in lossless compression with LRtimelapse ? Because i want to use LRT sequences in my video software (EDIUS) to add some effects like zooming and other mouvements.

With LRTimelapse Pro you can either import the lossless TIFF intermediary files into your video processor or you can use the ProRes export - in terms of quality the latter is quite like lossless (it's what most of the pros use).
