Supports: WTV
WTV is Microsoft's container for recorded over-the-air TV, used by Windows Media Center starting with the TV Pack 2008 add-on for Vista and shipped with every Media Center edition of Windows 7. It wraps MPEG-2 or MPEG-4 video with MPEG-1 Layer II or Dolby Digital AC-3 audio — fine for playback on the original PC, awkward everywhere else once Media Center was removed from Windows 10 in July 2015 and EPG service ended January 14, 2020. JPG is the universal still-image format defined by ISO/IEC 10918-1 (1992), and pulling frames out of a WTV gives you images every browser, phone, photo viewer, and editing app can open.

WTV stores the full MPEG-2 or MPEG-4 video stream plus AC-3 audio for the entire recording — typically 4-8 GB for an hour of HD broadcast. A JPG is one frame of that stream, compressed once with DCT, with no audio. Expect the JPG to be hundreds of thousands of times smaller than the source WTV.
No. WTV recordings made from channels that broadcast with the CGMS-A "Copy Once" or "Copy Never" flags are encrypted and bound to the recording PC. They can't be re-encoded or frame-extracted by any third-party tool, including this one. Unprotected over-the-air ATSC recordings convert without issue.
The Time (seconds) field takes decimal seconds. For one minute thirty seconds into the recording, enter 90 (or 90.5 for half a second past that). For an hour, enter 3600. Submillisecond precision isn't supported — the closest decoded frame to your timestamp is returned.
Multiple Screenshots samples at the framerate or interval you specified — it doesn't extract every encoded frame in the source. At 1 fps from a 30-minute recording you'll get 1,800 frames; at one frame every 5 seconds you'll get 360. Increase the framerate or shorten the interval if you need denser sampling.
By default, yes — Image Resolution is set to Keep original, so a 1080P WTV gives 1920×1080 JPGs. Pick a preset (720P, 480P, etc.) or set a percentage to downscale. The tool preserves aspect ratio when you enter a single dimension.
They're identical files — same ISO/IEC 10918-1 stream, same DCT compression. The three-letter .jpg exists because MS-DOS and early Windows capped extensions at three characters. Modern apps accept both; pick .jpg for the shorter filename or .jpeg if your target system expects it.
Set Quality Preset to Highest, leave Image Resolution at Keep original, and pick a timestamp that lands on a relatively static scene (motion blur and interlacing artefacts are baked into the source MPEG-2 stream and no amount of JPG quality fixes them). For interlaced SD recordings consider deinterlacing the WTV first in a video editor.
This page only outputs JPG stills. For the underlying audio track, use WTV to MP3. For the full video re-encoded to a portable container, use WTV to MP4. For transparent stills with an alpha channel, use WTV to PNG.
Browser uploads cap effectively at the size your connection can sustain in a single session. A 6 GB recording on a 10 Mbps upload takes around 90 minutes; on flaky connections the session can time out. Try trimming the WTV first in Media Center, or grab the frame in VLC locally (Video → Take Snapshot) and skip the upload entirely.
