Heey,

My group mates and I tried to get a time measure for the detection of a minor change in a picture (loop of 300ms picture and edited picture with 50ms blank screens in between). We created .gif files to put this into directRT, but now it seems that the resolution that directRT gives is insufficient for our cause. Any clue on how we could solve this? Somehow cranking the quality of these .gif files up in directRT? Or even any other way to show these images (which we totally can make direct RT do the way we want) but simultaneously measure the time from the first showing of the stimulus picture to a response?

Eternal gratitude to anyone with a working answer!
Xx, Tina
