PNG to MTS Converter

PNG to MTS Converter

MTS is the file extension Sony and Panasonic camcorders write for AVCHD video, so converting a PNG to MTS means wrapping a still image inside an AVCHD-style clip — useful when you need a title card, logo plate, or placeholder that a camcorder timeline, AVCHD authoring tool, or older Blu-ray workflow will accept. The output is a short video that holds your image on screen for a set duration (5 seconds per frame by default); it is a still, not animation, encoded with H.264 video and an AC-3 audio track to match what AVCHD expects.

How to Convert PNG to MTS

1. Upload Your PNG File: Drag and drop your PNG onto the page, or click "Add Files". You can add several images at once.
2. Set the Duration: Use the Duration control to choose how long the image is held on screen — the default is 5 seconds per frame.
3. Pick a Quality Preset and Background Color: Choose a Quality Preset (Very High is the default), set a Background Color for any letterboxing, and optionally pick a Resolution Preset such as 1920×1080.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared.

Merge Images vs Video per Image

If you upload more than one PNG, the Merge strategy control decides the result. Merge images stitches every upload into one MTS clip, each image shown for the duration you set — handy for a quick title-plus-content slate. Video per image instead produces a separate MTS file per PNG, which is what you want when each still is its own clip for a camcorder timeline.

Frequently Asked Questions

Does this create a moving video or just a still image?

It produces a still. The PNG is held on screen for the duration you choose (5 seconds per frame by default), then encoded as an AVCHD-style H.264 clip. There is no motion, pan, or zoom — it is the equivalent of a freeze-frame slate, which is exactly what title cards and placeholders in a camcorder timeline usually need.

Why would I convert an image to MTS instead of MP4?

Only for AVCHD-specific workflows. MTS/AVCHD plays on camcorders and Blu-ray-era hardware but is not natively supported on iPhone, iPad, or most social platforms. If your goal is sharing or web playback, convert the PNG to MP4 instead — MP4 uses the same H.264 codec but in a container that phones, browsers, and editors handle natively.

What video and audio codecs does the MTS output use?

The clip is encoded with H.264 / MPEG-4 AVC video, which is the codec the AVCHD specification defines. Audio defaults to Dolby AC-3, the standard AVCHD audio format. Because a PNG has no sound, any audio track present is silent.

What resolution will my MTS file be?

By default the image is fit to a 1080-class frame, and you can pick a Resolution Preset such as 1920×1080 or 1280×720. AVCHD itself supports 720×480/576, 1440×1080, and 1920×1080, with 1080/50p and 60p added in the 2011 AVCHD 2.0 update. The Background Color control fills any area left over when your PNG's aspect ratio doesn't match the chosen frame.

Is the .MTS extension the same as .M2TS?

They are the same AVCHD transport-stream container with different extensions by convention: cameras write .MTS directly to the memory card, and that file is commonly renamed .M2TS once imported to a computer via the manufacturer's software. The output here uses the .MTS extension; if your tool expects .M2TS, renaming the file is usually enough.

Can my PNG's transparency survive the conversion?

No — AVCHD video has no alpha channel, so any transparent areas in the PNG are flattened against the Background Color you select (black by default). If you need the transparent edges preserved, keep the file as PNG or convert PNG to MP4; video formats in general are opaque. In our testing, a transparent-background PNG converted to MTS came out with those regions rendered as solid black unless we changed the background color first.
