AVIF to MTS Converter

AVIF to MTS — MTS, M2TS or TS?

Converting an AVIF image to .mts encodes the picture as H.264 video inside an MPEG transport stream and holds it on screen for a duration you choose. The question almost everyone actually has is which of the three transport-stream extensions to pick, because .mts, .m2ts and .ts all wrap the same underlying stream and different software insists on different ones. Short answer: choose .mts when you are matching camcorder footage or an AVCHD-era editing project, .m2ts when the target is Blu-ray-style delivery or files already transferred from a camera, and .ts for broadcast and streaming tooling. If nothing downstream demands a transport stream at all, AVIF to MP4 is smaller and plays on far more devices.

Side-by-side: MTS, M2TS, TS and MP4

When to Pick MTS

• You are cutting a still into an AVCHD-era camcorder project and want every clip on the timeline to share one extension.
• A capture, ingest or authoring tool validates the .mts extension specifically before it will import a file.
• You need a stream that can be joined or played from the middle: transport streams repeat their program tables, so a decoder can lock on partway through without an index at the start of the file.
• Your target device came out of the Sony and Panasonic AVCHD ecosystem, which has used H.264 in a transport stream since 2006.

When to Pick M2TS or TS Instead

• Blu-ray-style delivery, or matching files that a camera has already transferred to a computer as .m2ts, is a job for AVIF to M2TS.
• Broadcast, DVB capture and streaming muxers usually expect the plain .ts extension.
• For anything that has to reach a phone, browser or social platform, skip transport streams entirely and use AVIF to MP4.

How to Convert AVIF to MTS

1. Upload Your AVIF File: Drag and drop your .avif onto the page or click "+ Add Files". Several images can go in at once — Merge strategy chooses between "Merge images" (the default), which writes one stream, and "Video per image", which writes one file each.
2. Set the Duration: Open Image Duration and choose from the Duration dropdown, which runs from 1/60 of a second up to 10 seconds per frame. The default is 5 seconds and it sets how long the picture is held.
3. Set the Codec, Frame Size, and Background Color: Video Codec is preselected as H.264, the codec AVCHD is built on, with MPEG-2 the other choice transport streams reliably carry. Under Video resolution pick "Keep original", a fixed size such as 1920 x 1080, or a preset; Background Color (White by default) fills transparency and letterbox bars; and File Compression starts at the "Very High (Recommended)" Quality Preset.
4. Convert and Download: Click "Convert" and download the silent .mts file. No sign-up, no watermark.

Frequently Asked Questions

Is the .mts file this produces a real AVCHD file?

It is a standard MPEG transport stream carrying H.264 video, written with the .mts extension — which is what editors, players and ingest tools read when they open one. It is not a full AVCHD disc structure: camcorders write their transport streams in the Blu-ray packet variant inside a BDMV folder tree, alongside index and playlist files. Anything that reads transport streams will open this file; hardware that expects a complete AVCHD volume will not, and for that you would author the disc with dedicated software.

Does converting a still AVIF to MTS create motion?

No. A still .avif holds one picture, so the stream repeats that frame for the Duration you set and looks frozen. An AVIF that stores a timed image sequence is detected automatically and its frames are carried across as real motion.

Why is there no audio track?

Because a still image has no sound to encode, so the encoder skips the audio stage rather than writing a silent track. When a transport stream does carry audio in this ecosystem it is normally Dolby Digital AC-3, the codec the AVCHD specification names alongside linear PCM. To add sound, convert here and mux the audio in with a video editor.

Which video codec should I choose for a transport stream?

H.264 unless something specifically requires otherwise — it is preselected, it is what AVCHD uses, and it is what modern decoders expect inside a transport stream. MPEG-2 is the other codec transport streams carry dependably and is the right pick only for broadcast-era equipment. The remaining codecs in the list exist for other containers and are a poor match for .mts.

How long is the clip and how many frames does it hold?

The clip lasts exactly as long as the Duration you choose. Our pipeline encodes still-image input at one frame per second, so the default 5 seconds produces a five-frame stream: the duration in the stream is correct and players show a normal five-second clip, but nothing changes between frames so extra frames would only add size.

Will my AVIF's transparency survive?

No. Video frames have no alpha channel, so transparent and semi-transparent areas are composited onto the Background Color — white by default — before encoding, and the same colour fills the bars if your chosen frame size does not match the image's aspect ratio. Keep the file as an image with AVIF to PNG if the alpha matters.

Why does my phone or browser refuse to play the .mts file?

Transport streams were designed for broadcast and camcorder recording, not for consumer playback, and mobile operating systems and browsers generally do not register the .mts extension. Desktop players such as VLC and mpv open them, as do editors. For anything you intend to share, convert to AVIF to MP4, or bring existing camcorder footage over with MTS to MP4.

Can I put several AVIF images into one .mts file?

Yes. Upload them together and leave Merge strategy on "Merge images"; each is held for the Duration you set and they are written into a single stream in upload order. "Video per image" produces one .mts per picture instead.

What happens to my file after the conversion?

Your AVIF is uploaded over an encrypted connection, converted on our servers, and deleted automatically a few hours later. There is no sign-up, no watermark, and files are never shared or made public.
