VOB в WebP Часто задаваемые вопросы о конвертации
How do I extract images from a VOB video as WebP?
+
Upload your VOB video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of WebP 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 WebP images have?
+
Source resolution. A 1080p VOB produces 1920×1080 WebP stills; a 4K source produces 3840×2160 stills. Downscale in the options panel if needed.
Могу я извлечь одну рамку в определённое время?
+
Yes. Use the timestamp picker on the upload preview to scrub to the exact moment, then click 'extract this frame as WebP'.
Извлечение рамы пропало?
+
Each frame is decoded from the VOB (lossless) and re-encoded as WebP. If WebP is lossless (PNG), no quality is lost. If WebP is JPG, we use high quality (90) by default.
Will the WebP stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (WebP_00001.WebP, WebP_00002.WebP, ...) 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 WebP 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 WebP 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 WebP files?
+
No. Both the source VOB and the WebP 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 WebP frames.
What if my VOB has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the WebP stills are spaced evenly in time regardless of how the source was encoded.
