FLV to JPEG Conversion FAQ
How do I extract individual frames from FLV as JPEG images?
+
Upload the FLV and open the options. Frame Extraction has two modes: Single Frame saves one JPEG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a JPEG image. There is no every-Nth-frame or one-per-second mode. 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.
At what resolution do the extracted JPEG images come out?
+
Same resolution as the source FLV: a 1080p FLV produces 1920x1080 JPEG frames, a 4K FLV produces 3840x2160 JPEG 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 an FLV as JPEG?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 JPEG images. For a single still, choose Single Frame and enter the second you want instead.
Will the JPEG frames preserve the FLV colour grading?
+
HDR footage is not tone-mapped: each frame is converted from the FLV as it is decoded, so a frame from an HDR FLV can look flat or washed out as a JPEG. Standard (SDR) video keeps its colours.
How long does frame extraction from FLV to JPEG take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Is my FLV private during frame extraction?
+
Yes. Uploaded FLV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted JPEG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why are my extracted JPEG frames blurry?
+
Almost always motion blur baked into the source FLV (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 FLV.
Can the converter pick one frame per scene change in the FLV?
+
No. The converter has no scene detection and no one-per-second mode: it saves either a single frame at the second you enter or every frame. For one image per scene, extract single frames at the times where the scenes change.
