I've had difficulty phrasing this question. Basically, at my current design i have a "scrubbing" slider, moving the slider will affect the video preview.
I've added another component. There is a PLUS(+) and MINUS(-) buttons on both sides of the slider respectively. Clicking those, will advance the video in one frame at a time (respectively).
I've made some testing and apparently users think it's an indicator labels, and not buttons, not talking about them thinking it's + - frame advancer.
What is your recommendations to solve this issues? without hurting the UI?
