One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as a PNG. There is no field for a list of times, so run the conversion again for each extra timestamp.
Shin MOV bidiyo na na sirri ne yayin fitar da firam?
+
Yes. Uploaded MOV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
