Hi, we are considering to buy Direct RT and I would like to know if it allows the presentation of visual cues (e.g. gif images) superimposed to short video sequences.

If this is not the case, is the solution proposed below correct?

If graphic cues couldn't be superimposed to video sequences these cues could be inserted in the video sequences (a rather tedious task) by editing single frames. Since I am interested in recording reaction times to these signals, should I keep the video frame rate the same as the monitor refresh rate? Please, keep in mind that I'm interested in measuring the reaction time to these graphic cues (participants would have to press a button when the cues appear on the screen). As far as I understand, if video frame rate and monitor refresh rate are the same, I should be able to get the reaction time to the graphic cues by substracting the reaction time mesured from the beginning of video presentation minus the cue presentation starting time.

Would this approach work?

Thanks in advance,

Alvaro
