How do I extract frames from a WMV video as JPG images?
+
Upload the WMV file and the converter exposes a frame picker: every Nth frame, frames at explicit timestamps, or one frame per second. Each chosen frame is encoded as a separate JPG file and bundled as a ZIP for download.
At what resolution does the extracted JPG image come out?
+
Same pixel dimensions as the source WMV — a 1080p video produces 1920x1080 JPG frames, a 4K source produces 3840x2160 JPG frames. Resize after extraction if you need smaller thumbnails (we have a /image-resize/ tool for that).
Can I extract every frame from a WMV file as JPG?
+
Yes, but be careful with the file count — a 30fps 1-minute video produces 1,800 frames. We pack them into a ZIP automatically. For longer clips the "1 per second" option (60 frames) or named timestamps are usually more useful than every-frame.
Will the JPG images preserve WMV HDR color?
+
HDR sources are tone-mapped to SDR when extracting to JPG (PNG / JPG can't store HDR pixel ranges natively). WebP / AVIF / TIFF JPG can preserve a wider gamut if the JPG encoder supports 10-bit, exposed in advanced options.
What is the file size of one extracted JPG frame?
+
Depends on resolution and codec. A 1080p PNG frame is 2-5 MB; a 1080p WebP frame at quality 80 is 80-200 KB; a JPG quality-85 frame is 200-500 KB. Multiply by frame count to size the ZIP — every-frame PNG of a 10-minute 1080p video is around 50 GB.
Does the extracted JPG keep camera EXIF metadata?
+
The WMV container does not store per-frame EXIF the way a still camera does, so the JPG 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 chronologically.
How long does frame extraction from WMV to JPG take?
+
Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute WMV -> JPG bundle finishes in about 1 minute regardless of frame count, because the bottleneck is the JPG encoder not the demuxer.
Can I extract frames at specific timestamps in the WMV?
+
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 JPG file per timestamp. Useful for chapter thumbnails or hero scene reference shots.
Is my WMV video private during JPG extraction?
+
Yes — same privacy model as every conversion. Source video and extracted frames are processed in isolated workers and deleted within minutes of completion.
Why are my extracted JPG frames blurry?
+
Almost always motion blur from the source WMV — 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.
Does this tool support one-frame-per-scene-change extraction?
+
Not in the basic flow — use the "1 per second" option as an approximation, then visually pick scene-change frames. A dedicated scene-detection extractor is on the roadmap.
Can I use the extracted JPG frames commercially?
+
Yes, subject to whatever licence governs the source WMV content. The format change adds no claim — we apply no watermark, embed no tracking, and claim no licence on the JPG output.
