Same resolution as the MP4 video — a 1080p source produces 1920×1080 BMP frames; a 4K source produces 3840×2160 BMP frames. Resize after extraction if you need smaller thumbnails.

Yes — colour is decoded with the same matrix the source MP4 uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to BMP (PNG / JPG can't store HDR pixel ranges natively).

Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute MP4 → BMP bundle finishes in about 1 minute regardless of frame count, because the bottleneck is the BMP encoder, not the demuxer.

Àkò lè fi àwọn fèrèsé pamọ́ sí àwọn ààyè-iṣẹ́ àìdálẹ̀ nínú àwòrán MP4?

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 or scene reference shots.
