Shin an fitar da BMP yana riƙe da metadata na kamara EXIF?
+
The MPG container does not store per-frame EXIF the way a still camera does, so the BMP 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 MPG zuwa BMP?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute MPG → BMP bundle finishes in about a minute regardless of frame count, because the bottleneck is the BMP encoder, not the MPG demuxer.
Shin zan iya fitar da firam a cikin lokaci na musamman cikin MPG?
+
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 BMP file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
