Upload the M4V file and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as a separate BMP file and bundled as a ZIP archive for download.

At what resolution does the extracted BMP image come out?

Same resolution as the M4V video — a 1080p source produces 1920×1080 BMP frames; a 4K source produces 3840×2160 BMP frames. Use /resize-image/ after extraction if you need smaller thumbnails or social-media-sized assets.

Yes — colour is decoded with the same matrix the source uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to BMP (PNG / JPG cannot store HDR pixel ranges natively); the tone-mapping curve is the same one used by mpv / ffmpeg.

Does the extracted BMP keep any camera metadata?

The M4V container does not store per-frame EXIF the way a still camera does, so the extracted 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 chronology after download.

Can I extract frames at specific timestamps in the M4V video?

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 generating poster frames for HTML5 video.

Is my M4V video private during frame extraction?

Yes — same privacy model as every conversion. The source video and extracted frame bundle are processed in isolated workers and deleted within minutes of completion. No frame is ever shown to a human reviewer.

Why are my extracted BMP frames blurry?

Almost always motion blur from the source (the camera was moving when the frame was captured). Try picking timestamps from static scenes, or extract several adjacent frames and choose the sharpest. The pipeline does not synthesize sharpness — for that, use /upscale/ on the extracted BMP afterwards.

Can I use the extracted BMP frames commercially?

Yes, subject to whatever licence governs the source M4V content. The format change adds no claim — we add no watermark, embed no tracking, and claim no licence over the BMP output. Public-domain video produces public-domain frames; your own footage stays your own.
