At what resolution does the extracted TIFF image come out?
+
Same pixel dimensions as the source 3GP — a 1080p video produces 1920x1080 TIFF frames, a 4K source produces 3840x2160 TIFF frames. Resize after extraction if you need smaller thumbnails (we have a /image-resize/ tool for that).
Can I extract every frame from a 3GP file as TIFF?
+
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 TIFF images preserve 3GP HDR color?
+
HDR sources are tone-mapped to SDR when extracting to TIFF (PNG / JPG can't store HDR pixel ranges natively). WebP / AVIF / TIFF TIFF can preserve a wider gamut if the TIFF encoder supports 10-bit, exposed in advanced options.
What is the file size of one extracted TIFF 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 TIFF keep camera EXIF metadata?
+
The 3GP container does not store per-frame EXIF the way a still camera does, so the TIFF 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 3GP to TIFF take?
+
Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute 3GP -> TIFF bundle finishes in about 1 minute regardless of frame count, because the bottleneck is the TIFF encoder not the demuxer.
Can I extract frames at specific timestamps in the 3GP?
+
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 TIFF file per timestamp. Useful for chapter thumbnails or hero scene reference shots.
Is my 3GP video private during TIFF extraction?
+
Yes — same privacy model as every conversion. Source video and extracted frames are processed in isolated workers and deleted within minutes of completion.
