VOB to JPEG Conversion FAQ
How do I extract individual frames from VOB as JPEG images?
+
Upload the VOB and open the options. Frame Extraction has two modes: Single Frame saves one JPEG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a JPEG image. There is no every-Nth-frame or one-per-second mode. VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added. JPEG is the same standard as JPG and JFIF — the four-letter extension is the original, and the three-letter one exists only because of the DOS 8.3 filename limit.
Will subtitles show up in the JPEG frames I extract?
+
Not if they are a real subtitle track. A VOB keeps subtitles as their own stream and the player draws them over the picture at playback time, so the decoded frame the converter writes out as a JPEG has clean pixels underneath. Subtitles that were burned into the video before it ever became a VOB are a different matter — by then they are part of the image and every extracted frame keeps them.
At what resolution do the extracted JPEG images come out?
+
Same resolution as the source VOB: a 1080p VOB produces 1920x1080 JPEG frames, a 4K VOB produces 3840x2160 JPEG frames. The converter does not upscale or downsample — pixel dimensions are pulled straight from the decoded frame. Use /resize-image/ after extraction if you need smaller thumbnails.
Can I extract every frame of a VOB as JPEG?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 JPEG images. For a single still, choose Single Frame and enter the second you want instead.
Will the JPEG frames preserve the VOB colour grading?
+
HDR footage is not tone-mapped: each frame is converted from the VOB as it is decoded, so a frame from an HDR VOB can look flat or washed out as a JPEG. Standard (SDR) video keeps its colours.
How long does frame extraction from VOB to JPEG take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Is my VOB private during frame extraction?
+
Yes. Uploaded VOB files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted JPEG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why are my extracted JPEG frames blurry?
+
Almost always motion blur baked into the source VOB (the camera or subject was moving while that frame was captured). Try picking timestamps from static scenes, or extract several adjacent frames and pick the sharpest. The pipeline does not synthesize detail that is not in the original VOB.
Can the converter pick one frame per scene change in the VOB?
+
No. The converter has no scene detection and no one-per-second mode: it saves either a single frame at the second you enter or every frame. For one image per scene, extract single frames at the times where the scenes change.
