We do a lot of rodeos, we love vMix replay, however, our life would be easier if we could set the in point before the button is pushed.
For example, during the rodeo anticipating the ‘head nod’ if difficult. If we could hit the IN as the gate opens eg: 12:08:13:10, vMix would set it 12:08:11:10, then we would capture the head nod, its like hindsight. If the time could be adjusted the feature could be customised for different events.
Many broadcast cameras have a ‘cache’ feature so your not rolling all day, you set the cache anywhere from 2-30secs, the cameras are buffering, vMix would just need to move the in-point.
