MP4 до BMP Найчастіші запитання щодо конверсій
How do I extract images from a MP4 video as BMP?
+
Upload your MP4 video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of BMP stills.
How many frames will I get from the MP4?
+
By default, one frame per second of MP4 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 BMP images have?
+
Source resolution. A 1080p MP4 produces 1920×1080 BMP stills; a 4K source produces 3840×2160 stills. Downscale in the options panel if needed.
Чи можу я витягти окрему рамку за конкретним часовим штампом?
+
Yes. Use the timestamp picker on the upload preview to scrub to the exact moment, then click 'extract this frame as BMP'.
Чи не втрачає він каркас?
+
Each frame is decoded from the MP4 (lossless) and re-encoded as BMP. If BMP is lossless (PNG), no quality is lost. If BMP is JPG, we use high quality (90) by default.
Will the BMP stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (BMP_00001.BMP, BMP_00002.BMP, ...) 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 MP4?
+
Yes — pick the 'contact sheet' option to get a single BMP containing a grid of thumbnails, useful for storyboarding or video previews.
How large can my MP4 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 MP4 to BMP extraction free?
+
Yes, within the free size limit. PRO unlocks larger files, higher extraction rates, and parallel processing.
Does PDF.to keep my MP4 or extracted BMP files?
+
No. Both the source MP4 and the BMP output ZIP are deleted within an hour. Conversion runs in an isolated worker.
Can I extract images only from a section of the MP4?
+
Yes. Use the trim controls to set start and end times, and only the selected range produces BMP frames.
What if my MP4 has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the BMP stills are spaced evenly in time regardless of how the source was encoded.
