AVCHD to HEIC Converter

Grab a Still Frame From AVCHD: What This Tutorial Covers

AVCHD is the high-definition camcorder format Sony and Panasonic introduced in 2006 — H.264/AVC video wrapped in an MPEG transport stream, saved as the .mts or .m2ts files your camera writes to its memory card. This tool pulls a single frame out of that footage at the timestamp you choose and saves it as a HEIC image, so a paused moment from a clip becomes a compact still you can keep or share.

How to Convert AVCHD to HEIC

1. Upload Your AVCHD File: Drag and drop your .mts or .m2ts clip onto the page, or click "+ Add Files" to browse. The clip is uploaded over an encrypted connection — no app to install.
2. Set the Time (seconds): With "Specific Frame" selected, type the moment you want to capture, for example 2.100 for two seconds and 100 milliseconds. That single frame becomes your image.
3. Pick Quality Preset and Resolution: Leave Quality Preset on "Very High" for a near-lossless still, and keep the resolution on "Keep original" to hold the source's full HD detail, or choose a Preset Resolution to shrink it.
4. Convert and Download: Click "Convert" to get your HEIC file. No sign-up, no watermark.

Walk-through: Choosing the Right Frame and Settings

Because AVCHD footage is often recorded interlaced — the 60i and 50i modes the format supports weave two half-resolution fields into each frame — a still grabbed from fast motion can show fine horizontal "combing" lines along moving edges. The fix is to pick your timestamp on a calm part of the clip rather than mid-action. A few patterns that help:

• If a moving subject looks combed: scrub the "Time (seconds)" value a fraction of a second earlier or later to a frame where the subject is still, then re-convert.
• If you want the sharpest possible image: keep resolution on "Keep original" and Quality Preset on "Very High" so the frame keeps the camera's native 1920x1080 (or 1440x1080) detail.
• If you need a smaller file for the web: switch resolution to a Preset like 720p, or lower the Quality Preset a step — HEIC already encodes stills with HEVC, so it stays compact.
• If you want several stills from one clip: switch from "Specific Frame" to "Multiple Screenshots" to sample frames across the whole video at a chosen interval instead of one.

Common Errors and How to Fix Them

• "My HEIC file won't open on Windows" — HEIC is the format Apple devices use by default, and Windows often needs the HEVC codec/extension installed before the Photos app can show it. If you need a still that opens anywhere, convert to a more universal format with AVCHD to JPG or AVCHD to PNG instead.
• "The frame looks striped or combed" — that is interlacing from a 1080i clip; choose a lower-motion timestamp as described above.
• "My camera files are named .m2ts, not AVCHD" — that is normal. .mts is what the camcorder writes and .m2ts is the same footage after import to a computer; both are AVCHD and both upload here.
• "The image is darker or softer than the live video" — camcorder LCDs often boost brightness and sharpness; the extracted frame reflects the actual recorded pixels.
• "Convert returns an error on a whole memory-card folder" — upload the individual .mts/.m2ts clip, not the camera's BDMV/STREAM folder structure.

When This Doesn't Work

If the clip is copy-protected, was only partially copied off the card (AVCHD splits long recordings across multiple files), or is truncated, frame extraction can fail. In those cases, copy the complete clip off the camera first, or if you need a longer moment rather than one frame, convert the whole clip to a standard video and screenshot from a player. For stills you intend to email or post publicly, prefer JPG over HEIC for compatibility.

Frequently Asked Questions

Does this extract one frame or the whole video?

By default it grabs a single still at the "Time (seconds)" you set under "Specific Frame" mode. Switch to "Multiple Screenshots" if you want it to sample many frames across the clip instead.

Why is my HEIC image striped or combed along moving edges?

AVCHD supports interlaced recording (the 60i/50i modes), where each frame is built from two fields captured a fraction of a second apart. On fast motion those fields don't line up, producing comb lines. Picking a low-motion timestamp avoids it.

How big will the resulting still be?

It depends on the source resolution and Quality Preset. AVCHD records at 1920x1080 or 1440x1080, so on "Keep original" you get a full-HD still; HEIC stores it with HEVC compression, which typically yields a noticeably smaller file than a JPEG of similar visual quality.

My phone won't open the HEIC — what should I do?

HEIC is well supported on recent Apple devices and on Android 10 and later, but older phones and Windows PCs may need an added codec. In our testing, the most reliable fix for cross-device sharing is to re-run the clip through AVCHD to JPG, which every image viewer opens.

What's the difference between the .mts and .m2ts files from my camcorder?

They hold the same AVCHD video. Cameras write .mts to the memory card, and the file is commonly renamed to .m2ts once imported to a computer. Both upload to this tool without any change in quality.

Does extracting a frame re-compress the whole video?

No. The tool decodes only the frame at your chosen timestamp and encodes that single image as HEIC; the rest of the clip is untouched.
