VOB 에 TIFF 변환 FAQ
How do I extract frames from a VOB video as TIFF images?
+
Upload the VOB and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as an individual TIFF file and the full set is bundled into a ZIP archive for download.
At what resolution does each extracted TIFF frame come out?
+
The same resolution as the VOB video — a 1080p VOB produces 1920×1080 TIFF frames; a 4K VOB produces 3840×2160 TIFF frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Can I extract every single frame from VOB as TIFF?
+
Yes, but be careful with file count — a 30fps 1-minute VOB produces 1,800 TIFF frames. We pack them into a ZIP automatically. For longer clips, the "1 per second" option (60 frames) or specific timestamps gives a manageable result.
Will the extracted TIFF images preserve the VOB color grading?
+
Yes — colour is decoded with the matrix the source VOB uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR on extraction to TIFF because most TIFF formats (PNG, JPG) cannot store HDR pixel ranges natively.
What is the file size of one extracted TIFF frame?
+
Depends on resolution and TIFF 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 VOB produces ~50 GB total.
Does the extracted TIFF retain EXIF camera metadata?
+
The VOB 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 by capture order.
How long does frame extraction from VOB to TIFF take?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute VOB → TIFF bundle finishes in about a minute regardless of frame count, because the bottleneck is the TIFF encoder, not the VOB demuxer.
Can I extract frames at specific timestamps in the VOB?
+
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, scene reference shots, or thumbnailing long lectures.
Is my VOB video private during frame extraction?
+
Yes — same privacy model as every conversion. Source video and extracted TIFF frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
Why are my extracted TIFF frames blurry?
+
Almost always motion blur baked into the VOB source — the camera or subject was moving when the frame was captured. Pick timestamps from static scenes, or extract adjacent frames and choose the sharpest. The pipeline does not synthesize detail that was not there.
Can I extract one TIFF per scene change rather than per timestamp?
+
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; ping us if it would unblock a specific workflow.
Can I use the extracted TIFF frames commercially?
+
Yes, subject to whatever licence governs the source VOB content. The format change adds no claim — we add no watermark and assert no licence over the TIFF output. Copyright tracks the source, not the converter.
