FLV ut PNG Quaestiones Frequentes de Conversionibus
How do I extract frames from a FLV video as PNG images?
+
Upload the FLV and the converter exposes a frame-extraction picker: every Nth frame, frames at specific time stamps, or one frame per second. Each chosen frame is encoded as an individual PNG file and the full set is bundled into a ZIP archive for download.
At what resolution does each extracted PNG frame come out?
+
The same resolution as the FLV video — a 1080p FLV produces 1920×1080 PNG frames; a 4K FLV produces 3840×2160 PNG 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 PNG?
+
Si, sed cum archivio numerum prudentiam habes — 30 fps 1-minutus FLV 1800 PNG frames produxit. Automate in ZIP compacem. Pro longissime clipibus, "1 per secundum" optionis (60 frames) vel specificae tempore-marcae maneabiliam res consecutae sunt.
Will the extracted PNG 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 PNG because most PNG formats (PNG, JPG) cannot store HDR pixel ranges natively.
What is the file size of one extracted PNG frame?
+
Depends on resolution and PNG 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 PNG retain EXIF camera metadata?
+
The FLV container does not store per-frame EXIF the way a still camera does, so the PNG 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 PNG take?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute FLV → PNG bundle finishes in about a minute regardless of frame count, because the bottleneck is the PNG encoder, not the FLV demuxer.
Can I extract frames at specific timestamps in the FLV?
+
Si — optio amplificata comma separatum temporerum (e.g. `00:01:23,00:05:00,00:10:42`) listum acceptat et unicum PNG archivium pro tempore produxit. Utitur pro capitulis miniaturis, podium referentiae, vel longorum lectorum miniaturis.
Is my FLV video private during frame extraction?
+
Yes — same privacy model as every conversion. Source video and extracted PNG frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
Why are my extracted PNG frames blurry?
+
Quaedam semper motio blur in FLV fontem cocta est — camera vel res movit cum quadrum captum est. Temporales inscriptas ex staticis scenae selectare, vel adliquibus quadris extrahere et clarissimam selectare. Conductum non synthetizavit detalles qui non sunt.
Can I extract one PNG per scene change rather than per timestamp?
+
Non in flumine basile — "1 per secundum" optionem ut approximationem utentur, et deinde visualiter frames mutationis scenae selectant. Excavator descriptio-scenae dedicatus in matris schemato est; nos pinget si specificum flumen operae deblocaret.
Can I use the extracted PNG frames commercially?
+
Si, sub quo licentia continens fontem FLV contentum regulat. Formatum mutatio nullam affirmationem adiungit — nonum aquae signum adiungimus et nullam licentiam super PNG output assertum. Copyright fontem, non convertitorem, tracit.
