Need help?Convert AVIF to M4V
This converter wraps an AVIF still image in an M4V video container — Apple's .m4v flavour of MP4 that iTunes, the Apple TV app, and QuickTime treat as library video. The output is a single motionless frame held for a duration you choose: there is no motion and no audio track, just your picture turned into a short H.264 clip. That makes it useful for one specific job — dropping a photo slate or title card into an Apple-centric library or editing timeline alongside footage that is already .m4v. If you just want a shareable video with the standard extension, convert AVIF to MP4 instead; functionally it is the same file.

How to Convert AVIF to M4V
- Upload Your AVIF File: Drag and drop your AVIF onto the page or click "+ Add Files". Add several images if you want them stitched into one clip.
- Choose Merge Strategy: Pick "Merge images" to combine every uploaded file into a single M4V, or "Video per image" to get one M4V per picture.
- Set Image Duration and Background Color: "Image Duration" controls how long each frame is held (default "5 seconds per frame"); "Background Color" (default Black) fills any area the image does not cover after scaling.
- Convert and Download: Click "Convert" and download your M4V. No sign-up, no watermark.
Frequently Asked Questions
Is M4V actually different from MP4 here?
Not in any way that affects this file. M4V is Apple's naming convention for an MPEG-4 video container that uses the same ISO base media format as MP4, so the bytes are essentially an MP4 with a different extension. The only real distinction is Apple FairPlay DRM, which is applied solely to videos purchased from the iTunes Store — never to files you convert. Because the M4V we produce is DRM-free, you can rename it to .mp4 and any standard player will open it.
Does the M4V clip have any motion or sound?
No. A single AVIF is one frame, so the M4V shows that image held motionless for the duration you set, with no audio track — the Audio Codec option is hidden because a still has no sound. If you merge several images, you get a slideshow that cuts between them, but there is no movement within each frame.
Why would I convert an AVIF to M4V instead of MP4?
Only to match an Apple-ecosystem workflow that specifically expects .m4v, such as a title card going into an iTunes or Apple TV library, or a slate dropped onto an editing timeline next to existing .m4v footage. For any general-purpose video, the standard AVIF to MP4 extension is more widely recognized and produces the identical H.264 result.
Which codec does the M4V output use?
H.264 video, which is the codec M4V is conventionally built around and which Apple players expect. AVIF itself is an AV1-based still image, so the picture is decoded from AV1 and re-encoded to H.264 for the video — a one-time transcode. In our testing, a single 1080p AVIF held for 5 seconds at the default "Very High" quality produced a small H.264 M4V of a few hundred kilobytes, since one repeated frame compresses very efficiently.
Will the M4V keep AVIF's transparency or HDR?
No. AVIF supports an alpha channel and HDR, but M4V is an opaque H.264 video with neither, so any transparent regions are flattened onto the Background Color and wide-gamut color is mapped to standard video range. If preserving transparency matters, keep the image as a still and convert AVIF to PNG instead — PNG keeps the alpha channel.
Can I set the resolution to match my existing footage?
Yes. Under Advanced Options the video resolution can stay at the source size or be set to a Fixed Resolution such as 1920x1080 so the slate matches 1080p clips around it. Keep "Keep aspect ratio" on so a non-16:9 photo is letterboxed against the Background Color rather than stretched.
How are my files handled and how long are they kept?
Your AVIF is uploaded over an encrypted connection, converted on our servers, and the files are deleted automatically a few hours after conversion — no sign-up, no watermark, and nothing is shared or made public.
