That doesn't change the fact that ffmpeg currently isn't able to create EXIF metadata, even if it is able to parse it from some formats.

I was wondering the same thing, but my (perhaps newer) exiftool only reports the first three on a "bare" JPG file. OTOH, I believe ffmpeg is not capable of writing any metadata for JPG, not even non-EXIF.

Re: [FFmpeg-user] [ffmpeg] preserving metadata from .mp4 to .jpg/.png frames
Nope. The original video .mp4 has a start time and duration in the metadata. When converting to image files, the only timestamps they hold are for creation date (system time on script run).
