FLV to JPEG Conversion FAQ
How do I extract frames from an FLV video as JPEG images?
+
Upload the FLV 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 an individual JPEG file and the full set is bundled into a ZIP archive for download. FLV is the Flash Video container that carried essentially all web video from roughly 2003 until Flash was switched off at the end of 2020. JPEG is the same standard as JPG and JFIF — the four-letter extension is the original, and the three-letter one exists only because of the DOS 8.3 filename limit.
Can I get the JPEG frames without the subtitles?
+
Only if the FLV never had them burned in, because FLV has no selectable subtitle stream to switch off. Anything an FLV shows on screen is in the picture itself, so it is in every JPEG the extraction produces and no setting removes it afterwards. Where a separate subtitle file exists alongside the video, extract from a source that kept the two apart and the frames come out clean. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable.
What quality setting should I use for the JPEG output?
+
Quality 85 is the sensible default and the one used unless you change it — visually indistinguishable from the source at normal viewing distance, at roughly a fifth of the size of a lossless equivalent. Push to 95 for anything that will be edited or printed, and drop to 70 for thumbnails where size dominates. The bitstream is identical to a .jpg: DCT-based lossy compression, usually with 4:2:0 chroma subsampling, wrapped in a JFIF or Exif header.
At what resolution does each extracted JPEG frame come out?
+
The same resolution as the FLV video — a 1080p FLV produces 1920×1080 JPEG frames; a 4K FLV produces 3840×2160 JPEG frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Can I extract every single frame from FLV as JPEG?
+
Yes, but be careful with file count — a 30fps 1-minute FLV produces 1,800 JPEG frames. We pack them into a ZIP automatically. For longer clips, the "1 per second" option (60 frames) or specific timestamps gives a manageable result.
Will the extracted JPEG images preserve the FLV color grading?
+
Yes — colour is decoded with the matrix the source FLV uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR on extraction to JPEG because most JPEG formats (PNG, JPG) cannot store HDR pixel ranges natively.
What is the file size of one extracted JPEG frame?
+
Depends on resolution and JPEG codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p FLV produces ~50 GB total.
Does the extracted JPEG retain EXIF camera metadata?
+
The FLV container does not store per-frame EXIF the way a still camera does, so the JPEG 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 capture order.
How long does frame extraction from FLV to JPEG take?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute FLV → JPEG bundle finishes in about a minute regardless of frame count, because the bottleneck is the JPEG encoder, not the FLV demuxer.
Can I extract frames at specific timestamps in the FLV?
+
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 JPEG file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
Is my FLV video private during frame extraction?
+
Yes — same privacy model as every conversion. Source video and extracted JPEG frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
Why are my extracted JPEG frames blurry?
+
Almost always motion blur baked into the FLV source — the camera or subject was moving when the frame was captured. Pick timestamps from static scenes, or extract adjacent frames and choose the sharpest. The pipeline does not synthesize detail that was not there.
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.
