MTS to AVIF Converter

Grab a Still Frame from MTS as AVIF: What This Covers

This page pulls a single still frame out of an MTS (AVCHD camcorder) clip and saves it as an AVIF image — the modern, royalty-free format built on the AV1 codec that compresses harder than JPEG while keeping 10-bit color and HDR. This is frame extraction, not animation: you get one photo (or several separate stills via Multiple Screenshots), never a moving file.

How to Convert MTS to AVIF

1. Upload Your MTS File: Drag and drop your .mts or .m2ts clip onto the page, or click "+ Add Files". You can queue several camcorder clips and grab a frame from each.
2. Set the Frame in "Frame Selection": Under Advanced Options, keep "Specific Frame" and type the moment you want into "Time (seconds)" — e.g. 12 grabs the frame at the 12-second mark.
3. Tune "Quality Preset" and "Image resolution": Leave Quality Preset on "Very High (Recommended)" for a crisp still, or pick a "Preset Resolution" / "Keep original" to control output size.
4. Convert and Download: Click "Convert" and save the AVIF. No sign-up, no watermark.

Walk-through: Picking a Clean Frame from Interlaced Footage

The reason MTS frame grabs sometimes look "torn" is interlacing. Most AVCHD camcorders record 1080i, where each frame is stitched from two fields captured a fraction of a second apart. On a moving subject those two half-images don't line up, so a single extracted frame shows horizontal "comb" lines across anything that moved. Stills, slow pans, and locked-off tripod shots come out clean; fast action is where combing shows.

To get the sharpest possible still:

• Aim at a low-motion moment. Scrub the clip in any player first, note the timestamp where the subject is still, and type that into "Time (seconds)". A held pose beats a mid-swing frame every time.
• Keep resolution native for detail. Use "Keep original" (or a 1080p preset) so you keep the full sensor frame; only downscale if you specifically need a smaller file.
• Use "Very High" quality for archival stills. AVIF at high quality holds fine detail — skin texture, foliage — far better than an equivalent-size JPEG, so there's little reason to drop below Very High for a keepsake frame.
• Need several frames? Switch "Specific Frame" to "Multiple Screenshots" and set the "Capture Rate" to export evenly spaced stills across the clip instead of one.

Common Errors and How to Fix Them

• "My still has horizontal comb lines across the subject" — That's interlace combing from 1080i source on a moving frame. Pick a lower-motion timestamp, or grab the frame as JPEG/PNG and deinterlace in an editor before re-saving.
• "The AVIF won't open on my PC" — Windows Photos needs the AV1 Video Extension, and some older viewers and apps still can't read AVIF at all. Use the MTS to JPG converter for a still that opens everywhere.
• "My time value grabbed a black or blank frame" — Many camcorder clips open with a fraction of a second of black. Bump "Time (seconds)" forward by one or two seconds.
• "The output looks soft compared to the video" — A low Quality Preset or a downscaled resolution preset will soften the frame; set Quality Preset to "Very High" and resolution to "Keep original".

When This Doesn't Work

If you actually need motion rather than a still — for example to share the clip itself — frame extraction is the wrong tool; convert the whole video with the MTS to MP4 converter instead. Severely corrupted camcorder cards, or AVCHD clips split across multiple .mts segments that were never joined, may also fail to seek to the timestamp you typed; re-copy the files off the camera or join the segments first, then grab the frame.

Frequently Asked Questions

Does converting MTS to AVIF keep the video, or just one frame?

Just one frame. This tool seeks to the timestamp you set in "Time (seconds)" and saves that single still as an AVIF image — there is no animation in the output. If you want every frame as a separate still, switch to "Multiple Screenshots" and set a capture rate; if you want the moving video, convert MTS to MP4 instead.

Why does my extracted frame have horizontal lines through it?

AVCHD camcorders commonly record 1080i interlaced video, where each frame is built from two fields shot a moment apart. On a moving subject those fields don't align and you see "comb" lines. Choosing a still or slow-motion timestamp avoids it; for fast action, grab the frame as JPEG or PNG and deinterlace it in a video editor before exporting.

Will AVIF open on my computer and phone?

In current browsers, yes — AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+ and Edge 121+, roughly 93% of global browser usage per caniuse. Desktop apps lag: Windows Photos needs the free AV1 Video Extension, and some older photo viewers still can't open AVIF. If you need a file that opens anywhere, grab the frame as JPG or PNG instead.

Is AVIF better than HEIC for a camcorder still?

For sharing, usually yes. Both use modern video-codec compression, but AVIF is royalty-free (from the Alliance for Open Media) and far more broadly supported on the web — HEIC renders in only about 12% of browsers, essentially Safari alone, because of HEVC patent licensing. AVIF also supports 10- and 12-bit color and HDR, so it preserves a wide-gamut frame well.

What quality and resolution should I use for an AVIF still?

For a frame you want to keep, set "Quality Preset" to "Very High (Recommended)" and leave "Image resolution" on "Keep original" so you retain the full 1080-line frame. AVIF holds fine detail at high quality much better than a same-size JPEG. Drop the preset or downscale the resolution only when you deliberately need a smaller file for the web.

How are my MTS files handled and how long are they kept?

Your file is uploaded over an encrypted connection and the frame is extracted on our servers — there is no sign-up and no watermark. Uploaded files and their results are deleted automatically a few hours after conversion, and are never shared or made public.
