AVI کرنے کے لئے BMP تبادلوں کے اکثر پوچھے گئے سوالات
How do I extract frames from a AVI video as BMP images?
+
Upload the AVI 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 BMP file and bundled as a ZIP for download.
At what resolution does the extracted BMP image come out?
+
Same pixel dimensions as the source AVI — a 1080p video produces 1920x1080 BMP frames, a 4K source produces 3840x2160 BMP frames. Resize after extraction if you need smaller thumbnails (we have a /image-resize/ tool for that).
Can I extract every frame from a AVI file as BMP?
+
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 BMP images preserve AVI HDR color?
+
HDR sources are tone-mapped to SDR when extracting to BMP (PNG / JPG can't store HDR pixel ranges natively). WebP / AVIF / TIFF BMP can preserve a wider gamut if the BMP encoder supports 10-bit, exposed in advanced options.
What is the file size of one extracted BMP 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 BMP keep camera EXIF metadata?
+
The AVI container does not store per-frame EXIF the way a still camera does, so the BMP 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 AVI to BMP take?
+
Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute AVI -> BMP bundle finishes in about 1 minute regardless of frame count, because the bottleneck is the BMP encoder not the demuxer.
Can I extract frames at specific timestamps in the AVI?
+
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 BMP file per timestamp. Useful for chapter thumbnails or hero scene reference shots.
Is my AVI video private during BMP 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 BMP frames blurry?
+
Almost always motion blur from the source AVI — 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 BMP frames commercially?
+
Yes, subject to whatever licence governs the source AVI content. The format change adds no claim — we apply no watermark, embed no tracking, and claim no licence on the BMP output.
