CRF sets up a constant compression ratio in a way that every frame gets the number of bits needed to achieve a certain perceptual quality.
Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.
This option controls the number of frames per second. It changes the playback smoothness only, not the output video duration or video playback speed.

m4v

M4V is a video container format developed by Apple Inc. and introduced alongside the iTunes Video Store in October 2005. Technically, M4V is nearly identical to the standard MP4 format (MPEG-4 Part 14), with the primary distinction being optional FairPlay DRM protection applied to purchased content from the iTunes Store. Unprotected M4V files are fully compatible with any player that handles MP4, as the underlying container structure and codec support are the same. The format typically contains H.264 video and AAC audio, supporting resolutions up to 4K and features like chapter markers, subtitle tracks, and metadata tags for title, artwork, and ratings. Apple chose the M4V extension to distinguish iTunes content from generic MP4 files, primarily so that DRM-protected purchases would be recognized by the Apple ecosystem of devices and software. M4V files play natively on macOS, iOS, iPadOS, and Apple TV, and unprotected versions work seamlessly in most major media players across all platforms. The format gained significant traction as the iTunes Store became a dominant platform for purchasing and renting digital movies and TV shows. Compatibility with the broader MP4 ecosystem means that video and audio streams within DRM-free M4V files can be processed by virtually any modern editing or transcoding tool without conversion.

hevc

HEVC (High Efficiency Video Coding), also designated as H.265 and MPEG-H Part 2, is a video compression standard developed jointly by the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Approved in January 2013, HEVC was designed as the successor to H.264/AVC with the primary goal of doubling the compression efficiency — achieving equivalent visual quality at roughly half the bit rate. The standard accomplishes this through larger coding tree units of up to 64x64 pixels, more sophisticated motion prediction with 35 directional intra modes, advanced sample adaptive offset filtering, and parallel processing tools including tiles and wavefront parallel processing. HEVC supports resolutions from 320x240 up to 8192x4320 (8K UHD), making it future-proof for emerging display technologies. The codec is widely adopted in broadcasting, where it enables efficient delivery of 4K and HDR content over bandwidth-constrained channels, as well as in video conferencing and surveillance applications. Apple adopted HEVC as the default recording format for iOS devices beginning with iOS 11, dramatically expanding its consumer reach. Despite technical superiority over H.264, a complex and fragmented patent licensing landscape has driven interest in royalty-free alternatives like AV1, though HEVC remains deeply embedded in broadcast infrastructure and consumer electronics worldwide.

Superior Compression

HEVC shrinks M4V files dramatically while maintaining visual quality — save storage space and reduce bandwidth for streaming.

Modern Device Ready

HEVC plays on 4K TVs, recent smartphones, and modern computers. Convert your M4V to a format built for today and tomorrow.

Encrypted Transfer

Your M4V uploads and HEVC downloads are handled securely. Source files are deleted after conversion, output within 24 hours.

How to convert M4V to HEVC

1

Select or drag&drop M4V video to convert it to the HEVC format from your computer, iPhone or Android. Moreover, it is possible to choose it from your Google Drive or Dropbox account.

2

Now your video is uploaded and you can start the M4V to HEVC conversion. If it is needed, change the output format to one of the 37 video formats supported. After that, you can add more videos for batch conversion.

3

If you want, you can customize such settings as resolution, quality, aspect ratio and others by clicking the gear icon. Apply them to all the video files if necessary and click the button "Convert" to process.

4

Once your video is converted and edited, you can download it to your Mac, PC or another device. If necessary, save the file to your Dropbox or Google Drive account.

Frequently Asked Questions

Why convert M4V to HEVC?

HEVC offers up to 50% better compression than H.264. Your video maintains quality at half the file size — perfect for storage and streaming.

What plays HEVC video?

VLC, iPhones, iPads, recent Android devices, Windows 10/11, and most 4K TVs support HEVC playback natively or with a free codec pack.

Does HEVC keep the same quality?

Yes — HEVC is designed for equivalent quality at lower bitrates. Properly configured, the output is visually indistinguishable from the M4V source.

Is HEVC good for 4K content?

HEVC was built for high-resolution video. It handles 4K and even 8K content efficiently, which older codecs in M4V struggle to compress well.

How long does conversion take?

HEVC encoding is compute-intensive, but our cloud servers are optimized for it. Most files finish within minutes depending on length and resolution.
