HDR footage is not tone-mapped: each frame is converted from the MP4 as it is decoded, so a frame from a HDR MP4 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.

+
Yes. Uploaded MP4 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.
