Shin an fitar da TIFF yana riƙe da metadata na kamara EXIF?

The AV1 container does not store per-frame EXIF the way a still camera does, so the TIFF 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 AV1 zuwa TIFF?

Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute AV1 → TIFF bundle finishes in about a minute regardless of frame count, because the bottleneck is the TIFF encoder, not the AV1 demuxer.

Shin zan iya fitar da firam a cikin lokaci na musamman cikin AV1?

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 TIFF file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
