HDR footage is not tone-mapped: each frame is converted from the M4V as it is decoded, so a frame from a HDR M4V can look flat or washed out as a JPG. Standard (SDR) video keeps its colors.

One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as a JPG. There is no field for a list of times, so run the conversion again for each extra timestamp.
Shin M4V bidiyo na na sirri ne yayin fitar da firam?
+
Yes. Uploaded M4V files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted JPG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
