right mouse click on the full screen video and a popup menu gives the option.
technically, this is how my video clips are intended to be viewed, as playing them just once through is not nearly as effective, or powerful. since the hypnotic effect relies on many repetitions. be warned though. you might lose track of time or experience other side effects.
art4med, sorry i only just noticed your comment. i have recently decided, i no longer wish to use winmorph for abstract work, as it's too buggy and it's morph targets are not accurate enough to set up in the interface.
i guess this could be done with bone deformations? do you know if we can morph uv's yet in blender?
contemplexitus helped concept design the final color cycling, which is better than my first test renders i showed him. there were a few technical hurdles to overcome, but overall it was a lot of fun us brainstorming this project. hopefully he and i can work on more freaky collaborations in the future.
