Requests to use high precision for timing of images.
The actual time of the generated images will be within the range [requestedTime-toleranceBefore, requestedTime+toleranceAfter] and may differ from the requested time for efficiency.
Pass 0 for both toleranceBefore and toleranceAfter to request frame-accurate image generation; this may incur additional decoding delay. Default is infinity.


Request exact timing:

MBS("AVAsset.RequestImageTimePrecision"; $asset; 0; 0)

Request ± 0.5 seconds

MBS("AVAsset.RequestImageTimePrecision"; $asset; 0.5; 0.5)
