VOB kepada JPEG Soalan Lazim Penukaran
How do I extract images from a VOB video as JPEG?
+
Upload your VOB video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of JPEG stills.
How many frames will I get from the VOB?
+
By default, one frame per second of VOB runtime. The options panel lets you pick every frame, one per 5 seconds, only key-frames, or a custom interval.
What resolution will the extracted JPEG images have?
+
Source resolution. A 1080p VOB produces 1920×1080 JPEG stills; a 4K source produces 3840×2160 stills. Downscale in the options panel if needed.
Bolehkah saya mengekstrak satu bingkai pada setem masa tertentu?
+
Yes. Use the timestamp picker on the upload preview to scrub to the exact moment, then click 'extract this frame as JPEG'.
Adakah pengekstrakan bingkai kehilangan?
+
Each frame is decoded from the VOB (lossless) and re-encoded as JPEG. If JPEG is lossless (PNG), no quality is lost. If JPEG is JPG, we use high quality (90) by default.
Will the JPEG stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (JPEG_00001.JPEG, JPEG_00002.JPEG, ...) so they sort correctly. The options panel can also embed the source timecode in EXIF.
Can I make a contact-sheet or thumbnail grid from the VOB?
+
Yes — pick the 'contact sheet' option to get a single JPEG containing a grid of thumbnails, useful for storyboarding or video previews.
How large can my VOB video be?
+
The free plan has a size limit that varies by file type; PRO allows much larger files. Frame extraction is fast even for long videos.
Is the VOB to JPEG extraction free?
+
Yes, within the free size limit. PRO unlocks larger files, higher extraction rates, and parallel processing.
Does PDF.to keep my VOB or extracted JPEG files?
+
No. Both the source VOB and the JPEG output ZIP are deleted within an hour. Conversion runs in an isolated worker.
Can I extract images only from a section of the VOB?
+
Yes. Use the trim controls to set start and end times, and only the selected range produces JPEG frames.
What if my VOB has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the JPEG stills are spaced evenly in time regardless of how the source was encoded.
