Grab a JPG Still from AVCHD Footage: What This Tutorial Covers

AVCHD is the high-definition format Sony and Panasonic camcorders record to — H.264 video in a .mts or .m2ts transport stream — so a single frame can make a sharp 1920x1080 photo. This walk-through shows how to pull one frame at an exact timestamp or a whole run of stills, and how to avoid the comb-line artifacts that interlaced AVCHD can leave on a grabbed frame.

How to Convert AVCHD to JPG

1. Upload Your AVCHD File: Drag and drop your .mts / .m2ts clip onto the page, or click "+ Add Files". You can queue several clips at once; each is processed with the same settings.
2. Set Frame Selection: Under Advanced Options, choose Specific Frame and type the moment to capture in the Time (seconds) box — 2.100 means 2 seconds and 100 milliseconds in — or pick Multiple Screenshots and a capture rate to sample stills across the clip.
3. Choose Quality Preset and Resolution: Leave Quality Preset on "Very High (Recommended)" for a near-lossless JPG, and keep the resolution on "Keep original" to retain the camcorder's full 1080-line frame.
4. Convert and Download: Click "Convert". A single frame downloads as one JPG; a multi-frame run returns the images together. No sign-up, no watermark.

Walk-through: Picking the Right Frame and Resolution

The Time (seconds) field accepts decimals down to the millisecond, so scrub your clip in a player first, note the timestamp of the moment you want, and type it in. Capturing on a still or low-motion frame is the single biggest factor in image quality, because AVCHD is usually interlaced (1080i) — more on that below.

• One hero shot: Specific Frame, exact timestamp, Quality Preset "Very High", resolution "Keep original".
• Contact sheet of a sequence: Multiple Screenshots with a capture rate of one frame per second (or slower) to sample a long clip without thousands of images.
• Smaller files for email or web: drop Quality Preset to "High" or use Preset Resolutions to scale the frame down to 720p; a full-resolution still at top quality can run a few megabytes.
• Whole clip, not a still: if you actually want the video re-encoded rather than a photo, use AVCHD to MP4 instead.

Common Errors and How to Fix Them

• Frame shows comb lines / horizontal stripes on moving subjects — AVCHD 1080i stores each frame as two interlaced fields captured a moment apart; on motion they don't line up, producing "combing." Pick a frame where the subject is still, or grab from progressive (1080p/720p) footage if your camera offers it.
• Grabbed frame is black or blank — the timestamp landed before the first frame or past the end of the clip. Set the Time (seconds) value to a point you know has picture, e.g. a couple of seconds in.
• JPG looks soft compared to the video — JPG is a lossy format, so heavy compression blurs fine detail. Keep Quality Preset at "Very High" and resolution at "Keep original" for the sharpest result.
• File is too large to share — a full 1080p still at top quality can be several megabytes; shrink it afterward with the Image Compressor, or lower the Quality Preset before converting.
• Wrong moment captured — remember the Time value is in seconds with a decimal for milliseconds, not a frame number; 90 means 1 minute 30 seconds, not frame 90.

When This Doesn't Work

A frame grab only succeeds when the file decodes cleanly. Partial or corrupted .mts files copied from a camcorder without the full AVCHD folder structure (the BDMV/STREAM directories) sometimes won't seek to an arbitrary timestamp; copy the complete card contents and try again. Footage with broadcast-style DRM cannot be decoded by any web tool. And if you need pixel-perfect deinterlacing with a specific algorithm (Yadif, bob, blend), a desktop editor gives finer control than a one-click grab — but for a quick, sharp still from a low-motion AVCHD frame, the steps above are enough.

Frequently Asked Questions

Can I extract a single frame at an exact timestamp, or only a sequence?

Both. Choose Specific Frame and enter a time like 2.100 (2 seconds, 100 milliseconds) to capture one still, or choose Multiple Screenshots with a capture rate to sample frames across the whole clip. The two modes are mutually exclusive per conversion.

Why does my AVCHD frame grab have jagged horizontal lines?

That is combing, and it comes from interlacing. Most AVCHD camcorders record 1080i, where each video frame is built from two fields scanned a fraction of a second apart; when the subject moves, the two fields show it in slightly different positions and the still shows comb-tooth edges. Capturing a frame with little motion avoids it.

What resolution will the JPG be?

By default it matches the source frame, so a 1080-line AVCHD clip yields a 1920x1080 (or 1440x1080) JPG. AVCHD's HD modes top out at 1920x1080, so that is the most detail a frame can hold; you can scale down with Preset Resolutions but cannot add resolution the footage never had.

Will grabbing a frame re-compress and lose quality?

JPG is lossy, so the extracted still is re-encoded rather than copied bit-for-bit from the H.264 stream. In our testing, a full-resolution 1080p frame saved at the "Very High" preset produced a clean photo of roughly 1-3 MB with no visible blocking; dropping to lower presets trades sharpness for smaller files.

Do I need to upload the whole .mts file just to get one frame?

Yes — the file is uploaded over an encrypted connection so our servers can decode the H.264 stream and seek to your timestamp, then it is deleted automatically a few hours after conversion. There is no sign-up, no watermark, and files are never shared or made public. The output JPG is a standard image that opens in any viewer, browser, or editor.

Is AVCHD the same as MTS, M2TS, or MP4?

AVCHD is the recording format; .mts and .m2ts are the file extensions for its MPEG transport stream (.mts straight off the camera, .m2ts after import). MP4 is a different container entirely — if your file is MP4 rather than AVCHD, use an MP4-to-JPG tool instead, though the frame-grab steps are the same.
