How do I extract individual frames from AVI as TIFF images?
+
Upload the AVI 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 decoded from the AVI video stream, encoded as a separate TIFF file, and bundled as a ZIP for download.
At what resolution do the extracted TIFF images come out?
+
Same resolution as the source AVI: a 1080p AVI produces 1920x1080 TIFF frames, a 4K AVI produces 3840x2160 TIFF 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 a AVI as TIFF?
+
Yes, but mind the file count — a 30 fps 1-minute AVI produces 1,800 TIFF frames. We pack them into a single ZIP archive automatically. For longer clips, prefer the "1 per second" preset (60 frames per minute) or pick specific timestamps. An hour of AVI at every-frame would produce ~100,000 TIFF images.
Will the TIFF frames preserve the AVI colour grading?
+
Yes — colour is decoded with the same matrix the source AVI stream advertises (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to a TIFF that cannot store HDR pixel ranges natively (JPG, PNG-8). Target high-bit PNG-16 or TIFF if you need to keep extended dynamic range.
How big is one extracted TIFF frame on disk?
+
Depends on resolution and TIFF codec choice: a 1080p PNG frame is 2-5 MB lossless, a 1080p JPG at quality 85 is 200-500 KB. Multiply by frame count to size the ZIP — at the extreme, every-frame PNG extraction of a 10-minute 1080p AVI is roughly 50 GB and gets split across multiple ZIPs.
Does the extracted TIFF keep camera EXIF metadata?
+
A AVI container does not carry per-frame EXIF the way a still camera does, so the TIFF files come out with empty EXIF blocks. The converter does embed a `creation_time` field pointing at the source frame timestamp, so you can re-sort the bundle in chronological order or correlate with subtitle / chapter markers.
How long does frame extraction from AVI to TIFF take?
+
Frame decoding is fast — typically 20-30% of source duration. A 5-minute AVI -> TIFF bundle finishes in about 1 minute regardless of how many frames you pick, because the bottleneck is the TIFF encoder writing many small files in parallel, not the AVI demuxer.
Can I extract frames at exact timestamps inside the AVI video?
+
Yes — the advanced timestamp option accepts a comma-separated list (e.g. `00:01:23, 00:05:00, 00:10:42.5`) and produces one TIFF file per timestamp. Useful for chapter thumbnails, scene reference shots, or building a contact sheet for review.
Is my AVI private during frame extraction?
+
Yes — same privacy model as every conversion. Source AVI and the extracted TIFF bundle are processed in isolated workers and deleted within minutes of completion.
Why are my extracted TIFF frames blurry?
+
Almost always motion blur baked into the source AVI (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 AVI.
Can the converter pick one frame per scene change in the AVI?
+
Not in the basic flow — use the "1 per second" preset as a rough approximation and visually skim the bundle for scene changes. A dedicated scene-detect extractor (powered by ffmpeg select=gt(scene)) is on the roadmap and will land for TIFF export later this quarter.
Can I use the extracted TIFF frames commercially?
+
Yes, subject to whatever licence governs the source AVI content. The conversion is a format change — copyright on the content stays with whoever holds it on the AVI. We add no watermark, no embedded stamp, and claim no licence over the TIFF bundle.
