Shin an fitar da PNG yana riƙe da metadata na kamara EXIF?
+
The MOV container does not store per-frame EXIF the way a still camera does, so the PNG files come out with empty EXIF. We embed a `creation_time` field pointing at the source frame timestamp so you can re-sort the bundle by capture order.
Menene lokacin da za'a cire firam daga MOV zuwa PNG?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute MOV → PNG bundle finishes in about a minute regardless of frame count, because the bottleneck is the PNG encoder, not the MOV demuxer.

Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one PNG file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
