FLV to JPG Processing FAQ
How do I extract frames from a FLV video as JPG images?
+
Upload the FLV 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 JPG file and bundled as a ZIP archive for download.
At what resolution does the extracted JPG image come out?
+
Same resolution as the FLV video — a 1080p source produces 1920×1080 JPG frames; a 4K source produces 3840×2160 JPG frames. Use /resize-image/ after extraction if you need smaller thumbnails or social-media-sized assets.
Can I extract every frame from a FLV file as JPG?
+
Yes, but be careful with file count — a 30 fps 1-minute video produces 1,800 frames, and a 60 fps 10-minute video produces 36,000. We pack them into a ZIP automatically. For long clips use the "1 per second" option or specific timestamps to keep the bundle manageable.
Will the JPG images preserve the FLV color grading?
+
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 JPG (PNG / JPG cannot store HDR pixel ranges natively); the tone-mapping curve is the same one used by mpv / ffmpeg.
What is the file size of one extracted JPG frame?
+
Depends on resolution and target. A 1080p PNG frame is 2-5 MB; a 1080p JPG at quality-85 is 200-500 KB; a 1080p WebP at quality-85 is 100-300 KB. Multiply by frame count to size the ZIP — every-frame extraction of a 10-minute 1080p video as PNG is ~50 GB.
Does the extracted JPG keep any camera metadata?
+
The FLV container does not store per-frame EXIF the way a still camera does, so the extracted 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 by chronology after download.
How long does frame extraction from FLV to JPG take?
+
Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute FLV → JPG bundle finishes in about a minute regardless of frame count, because the bottleneck is the JPG encoder, not the demuxer.
Can I extract frames at specific timestamps in the FLV 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 JPG file per timestamp. Useful for chapter thumbnails, scene reference shots, or generating poster frames for HTML5 video.
Is my FLV 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 JPG 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 JPG afterwards.
Does this tool support extracting one frame per scene change?
+
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 (PySceneDetect-equivalent) is on the roadmap.
Can I use the extracted JPG frames commercially?
+
Yes, subject to whatever licence governs the source FLV content. The format change adds no claim — we add no watermark, embed no tracking, and claim no licence over the JPG output. Public-domain video produces public-domain frames; your own footage stays your own.
FLV (Flash Video) is a video container format developed by Adobe. It is commonly used for online video streaming and is supported by Adobe Flash Player.
