How do I extract individual frames from MOV as PNG images?
+
Upload the MOV 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 decoded from the MOV video stream, encoded as a separate PNG file, and bundled as a ZIP for download.
At what resolution do the extracted PNG images come out?
+
Same resolution as the source MOV: a 1080p MOV produces 1920x1080 PNG frames, a 4K MOV produces 3840x2160 PNG frames. The converter does not upscale or downsample — pixel dimensions are pulled straight from the decoded frame. Use /resize-image/ after extraction if you need smaller thumbnails.
Can I extract every frame of a MOV as PNG?
+
Yes, but mind the file count — a 30 fps 1-minute MOV produces 1,800 PNG frames. We pack them into a single ZIP archive automatically. For longer clips, prefer the "1 per second" preset (60 frames per minute) or pick specific timestamps. An hour of MOV at every-frame would produce ~100,000 PNG images.
Will the PNG frames preserve the MOV colour grading?
+
Yes — colour is decoded with the same matrix the source MOV stream advertises (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to a PNG that cannot store HDR pixel ranges natively (JPG, PNG-8). Target high-bit PNG-16 or TIFF if you need to keep extended dynamic range.
How big is one extracted PNG frame on disk?
+
Depends on resolution and PNG codec choice: a 1080p PNG frame is 2-5 MB lossless, a 1080p JPG at quality 85 is 200-500 KB. Multiply by frame count to size the ZIP — at the extreme, every-frame PNG extraction of a 10-minute 1080p MOV is roughly 50 GB and gets split across multiple ZIPs.
Does the extracted PNG keep camera EXIF metadata?
+
A MOV container does not carry per-frame EXIF the way a still camera does, so the PNG files come out with empty EXIF blocks. The converter does embed a `creation_time` field pointing at the source frame timestamp, so you can re-sort the bundle in chronological order or correlate with subtitle / chapter markers.
How long does frame extraction from MOV to PNG take?
+
Frame decoding is fast — typically 20-30% of source duration. A 5-minute MOV -> PNG bundle finishes in about 1 minute regardless of how many frames you pick, because the bottleneck is the PNG encoder writing many small files in parallel, not the MOV demuxer.
Can I extract frames at exact timestamps inside the MOV video?
+
Yes — the advanced timestamp option accepts a comma-separated list (e.g. `00:01:23, 00:05:00, 00:10:42.5`) and produces one PNG file per timestamp. Useful for chapter thumbnails, scene reference shots, or building a contact sheet for review.
Is my MOV private during frame extraction?
+
Yes — same privacy model as every conversion. Source MOV and the extracted PNG bundle are processed in isolated workers and deleted within minutes of completion.
Why are my extracted PNG frames blurry?
+
Almost always motion blur baked into the source MOV (the camera or subject was moving while that frame was captured). Try picking timestamps from static scenes, or extract several adjacent frames and pick the sharpest. The pipeline does not synthesize detail that is not in the original MOV.
Can the converter pick one frame per scene change in the MOV?
+
Not in the basic flow — use the "1 per second" preset as a rough approximation and visually skim the bundle for scene changes. A dedicated scene-detect extractor (powered by ffmpeg select=gt(scene)) is on the roadmap and will land for PNG export later this quarter.
Can I use the extracted PNG frames commercially?
+
Yes, subject to whatever licence governs the source MOV content. The conversion is a format change — copyright on the content stays with whoever holds it on the MOV. We add no watermark, no embedded stamp, and claim no licence over the PNG bundle.
