AVCHD to TIFF Converter

Extract an AVCHD Frame to TIFF: What This Tutorial Covers

This walks you through pulling one still frame out of an AVCHD camcorder clip and saving it as a TIFF — the lossless, print- and archive-grade image format. It is written for anyone staring at a folder of .MTS files who wants a single reference-quality picture out of the footage, not the whole moving clip. By the end you will know which file to upload, how to land on the exact frame, why some grabs show combing, and when this simple route breaks down.

How to Convert AVCHD to TIFF

1. Upload Your AVCHD Stream File: Drag and drop the individual .MTS or .M2TS clip onto the page, or click "+ Add Files" to browse. You can queue several clips and process them with the same settings.
2. Pick the Frame with Specific Frame: Open Advanced Options, go to Frame Selection, choose Specific Frame, and set Time (seconds) to the exact moment you want — 4.500 grabs the frame at 4.5 seconds. Switch to Multiple Screenshots to sample several frames across the clip instead.
3. Set Compression Type and Scale (Optional): Open the Compression Type dropdown and pick LZW or Deflate to keep the frame lossless, toggle File extension between TIFF and TIF, and use Resolution Percentage, Preset Resolutions, or Width x Height to scale down.
4. Convert and Download: Click "Convert" and download your TIFF. No sign-up, no watermark.

Walk-through: Landing on the Right Frame and Keeping It Lossless

The two settings that decide whether you get a clean, lossless still are Time (seconds) under Frame Selection and the Compression Type dropdown — and the second one has a trap worth knowing about.

• If you want one exact still: keep Specific Frame selected and type the timestamp into Time (seconds). The field takes decimals, so 12.250 lands on the frame a quarter-second past the twelve-second mark. Nudge it a few hundredths at a time to step between adjacent frames.
• If you want several stills from one clip: switch to Multiple Screenshots. This samples frames across the clip and returns them as separate TIFF files bundled in a ZIP — it does not build one multi-page TIFF. Each frame stays an independent image you can open or print on its own.
• If you want the frame truly lossless: this is the trap. The Compression Type dropdown defaults to JPEG, and JPEG compression inside a TIFF is lossy — it re-compresses the picture and quietly throws away detail. For an archival or print grab, change it to LZW or Deflate; both are lossless schemes defined in the TIFF 6.0 specification, so the saved pixels are bit-for-bit identical to what the decoder produced. LZW is the most broadly compatible; Deflate (ZIP) usually writes a slightly smaller file on photographic content. Choose None only if a legacy tool refuses to open any compressed TIFF.
• If your tools expect the three-letter extension: flip File extension to TIF. It is the same format — .tif is just the old DOS/Windows 8.3 spelling of .tiff — so the AVCHD to TIF route produces byte-identical output.

Common Errors and How to Fix Them

• "My frame has thin horizontal lines or combing" — Much AVCHD footage is interlaced (the 1080i mode), so a single frame is woven from two fields captured a fraction of a second apart. On anything that was moving you get comb-like lines. Fix: nudge Time (seconds) a few hundredths until you land on a moment where the subject is stationary; progressive (1080p/720p) clips do not show this.
• "The TIFF still looks soft or low-detail" — The frame is only as sharp as the H.264 the camcorder recorded — HD-era at best, softer in low light or fast motion. TIFF preserves that frame exactly; it cannot add detail the original encode never captured.
• "My saved TIFF looks blocky even though I picked Specific Frame" — You likely left Compression Type on the default JPEG, which is lossy. Re-run with LZW or Deflate for a clean, lossless still.
• "I only see folders on my camcorder card" — AVCHD is a folder tree, not a single file. Browse into PRIVATE/AVCHD/BDMV/STREAM/ and upload the individual .MTS clip; the top-level AVCHD folder is not a media file.
• "My browser won't display the downloaded TIFF" — That is expected. Outside Safari, no major browser renders TIFF in an <img> tag, and MDN lists it among image types to avoid for web content. TIFF is a download-and-open format for print and editing, not on-screen viewing.

When This Doesn't Work

A few situations fall outside this simple grab. If the card was copied incompletely, an .MTS clip can be truncated or reference a separate index that did not come along, and the decoder may stop before your timestamp — re-copy the whole PRIVATE/AVCHD tree from the card. If the moment you want only ever existed as a blur (fast pan, low light), no still format can rescue it; pick a steadier frame. And if your real goal is the moving footage in a modern, shareable container rather than a single picture, convert AVCHD to MP4 instead. For an on-screen or print still that opens everywhere, extract the frame as JPG.

Frequently Asked Questions

Does this convert the whole AVCHD video to TIFF, or just one frame?

Just one frame. The tool decodes the H.264 video inside your AVCHD clip, grabs the single frame at the timestamp you set under Frame Selection, and saves that as a static TIFF — the moving video is discarded. If you choose Multiple Screenshots you get several frames, but each arrives as its own separate TIFF inside a ZIP, never as one multi-page file. For the moving clip in a modern format, convert AVCHD to MP4 instead.

Is the TIFF actually lossless if the AVCHD source was already compressed?

The TIFF stores the decoded frame without adding any further loss, but it cannot undo what H.264 already discarded. AVCHD records lossy H.264, so the frame the decoder reconstructs is the ceiling — TIFF preserves those exact pixels verbatim when you pick a lossless Compression Type like LZW or Deflate. Think of TIFF here as a faithful, re-editable wrapper around whatever the codec produced, not a way to regain detail the camcorder never kept. If you leave the dropdown on its JPEG default, you actually add a second round of lossy compression, so switch it for archival work.

Which version of the TIFF spec does this output, and is it still maintained?

The output is a standard baseline TIFF conforming to TIFF 6.0, published 3 June 1992 — still the current revision of the format. TIFF was created by Aldus in 1986 and the specification passed to Adobe when it acquired Aldus in 1994; it has stayed stable since, which is part of why TIFF remains a dependable archival container decades later. The file opens in Photoshop, GIMP, ImageMagick, and essentially any imaging tool.

How big is a single extracted TIFF frame from HD AVCHD footage?

Larger than you might expect, because AVCHD is high-definition and TIFF can store every pixel without lossy compression. A full 1920×1080 frame as uncompressed 8-bit RGB is roughly 6.2 MB by raw pixel math (1920 × 1080 × 3 bytes ≈ 6.22 MB). In our testing, turning on LZW or Deflate trimmed that noticeably on natural-image frames with zero quality loss, which is why we recommend a lossless compressed scheme over writing the file uncompressed. At HD resolution the frame holds plenty of detail for decent small prints.

Why does my extracted frame have thin horizontal lines or look combed?

Because much AVCHD footage is interlaced — the 1080i mode weaves each frame from two fields captured a fraction of a second apart, so a frame grabbed mid-motion shows comb-like lines on the moving parts. Nudge the Time (seconds) value a few hundredths of a second to land on an instant where the subject is still, or pick a stationary moment in the clip. Progressive (1080p/720p) recordings do not have this issue. TIFF records whatever the decoder hands it faithfully, so a clean source frame is the only path to a clean still.

I only see folders on my camcorder card — which file do I upload?

AVCHD isn't a single file; it's a folder tree. Sony and Panasonic (who jointly introduced AVCHD in 2006) store recordings under PRIVATE/AVCHD/BDMV/STREAM/, where each clip is a .MTS file that becomes .M2TS once copied to a computer. Browse into that STREAM/ directory and upload the individual clip — uploading the top-level AVCHD folder won't work because it isn't a single media file. If you need the same frame in the three-letter spelling, the AVCHD to TIF tool is identical, and footage carrying the raw extension converts directly via M2TS to TIFF.

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

Your AVCHD clip is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
