Supports: TIFF, TIF
TIFF (Tagged Image File Format, Adobe-owned since the Aldus acquisition in 1994, spec revision 6.0) is the archive-grade still format used in print, scanning, RAW workflows, GIS, and medical imaging. M4V is Apple's video container — built on the MPEG-4 specification, restricted to H.264 video with AAC or Dolby Digital audio, and the native format Apple's iTunes Store, Apple TV, and the Photos / TV apps on macOS, iPadOS, and iOS handle without prompting. Turning a TIFF (or a numbered TIFF sequence) into an M4V is what lets a still image set behave like a real video on Apple hardware.
| Property | TIF / TIFF | M4V |
|---|---|---|
| Type | Still image (single page or multi-page) | Video container with audio |
| Standard owner | Adobe (TIFF 6.0, 1992; Library of Congress sustained format) | Apple (built on ISO/IEC 14496 / MPEG-4 Part 14) |
| Typical codecs / compression | LZW, ZIP/Deflate, PackBits, JPEG, ZSTD, CCITT G4, or uncompressed | H.264 video only; AAC or Dolby Digital (AC-3 / E-AC-3) audio |
| Bit depth | 1 to 32 bits per channel; 8/16/32-bit per channel common | 8-bit per channel (H.264 Baseline / Main / High); 10-bit needs High 10 profile |
| File size | Often 50-300 MB per high-res scan; 4 GB hard cap (classic TIFF) | Tens of MB to a few GB depending on length and bitrate |
| Native playback | Preview, Photoshop, GIMP, Fiji, IrfanView, all DAM tools | iTunes, Apple TV, Photos, QuickTime, VLC, MX Player, modern browsers via H.264 |
| DRM | None | Optional Apple FairPlay (used by iTunes Store purchases / rentals); your converted file is DRM-free |
| Best for | Lossless archiving, print, science, RAW intermediate | Playable video for Apple ecosystem, slideshow distribution, iTunes import |
| Image Duration setting | Effective frame rate | Use when |
|---|---|---|
| 1/60 second | 60 fps | Smooth motion playback, high-speed capture, gaming |
| 1/30 second | 30 fps | NTSC / web video standard, screen-recording sequences |
| 1/24 second | 24 fps | Cinema / film look, animation rendered "on ones" |
| 1/10 second | 10 fps | Stop-motion, GIF-like animation, traffic time-lapse |
| 1-2 seconds | 1 fps and below | Time-lapse slideshow, before/after photo comparisons |
| 3-10 seconds | Slideshow pacing | Photo album, document review, storyboard playback |
If you need broader cross-platform playback instead of M4V's Apple bias, convert to TIF to MP4 or TIF to MOV instead. Already have M4V and need MP4 for Windows / Android recipients? Use M4V to MP4.
Both wrap the same MPEG-4 streams, but M4V is what Apple's first-party apps (iTunes, TV, Photos, Books) treat as "video they own." iTunes shows the right metadata fields, the TV app sorts it into the correct library, and AirPlay to an Apple TV negotiates faster. M4V is also restricted to H.264 video with AAC or Dolby Digital audio — no AV1, VP9, or HEVC — so when you receive an M4V you know exactly what codecs you're dealing with. If your audience isn't on Apple devices, convert to MP4 instead for the broadest compatibility.
Name the files with a zero-padded numeric pattern — frame_0001.tif, frame_0002.tif, … frame_2400.tif. The converter sorts by filename, so padding is what keeps frame_10 from sorting before frame_2. Most render engines (Cinema 4D, Blender, Houdini, After Effects) already pad correctly. If your scanner or microscope used a non-padded scheme, batch-rename in Finder (Rename items… → Format) or Windows PowerToys before uploading.
In the default H.264 encode, yes — the resulting M4V is 8-bit per channel (H.264 Baseline / Main / High profile). True 10-bit per channel needs the H.264 High 10 profile, which Apple's TV app supports on Apple Silicon and recent A-series chips but isn't universal. For HDR scientific or VFX deliverables, render or convert to ProRes inside MOV first via TIF to MOV, which holds 10/12-bit cleanly. M4V is best treated as a viewing copy, not an archival master.
Match what the source was rendered at. CG / motion graphics: 24 fps (cinema) or 30 fps (web). Animation: 24 fps for "on ones," 12 fps for "on twos." Time-lapse from a DSLR shooting every 5 seconds at 10× speedup: 24 fps playback. Slideshow of family photos: 0.2-1 fps (use 3-10 seconds per image). The Image Duration dropdown is the inverse — 1/24 second per frame = 24 fps, 1/30 = 30 fps, 5 seconds = 0.2 fps.
The TIF-to-M4V flow renders silent video by default (TIFF has no audio track). To add music or narration, convert to M4V first, then mux audio in a video editor or with ffmpeg -i video.m4v -i audio.aac -c copy out.m4v. iMovie, Final Cut, and DaVinci Resolve all accept the resulting M4V on the timeline for adding a soundtrack non-destructively.
TIFF stores every pixel of every frame losslessly (often 50-300 MB per frame at print resolution). H.264 inside M4V uses inter-frame compression — it stores keyframes plus the differences between frames. A 200-frame TIFF sequence at 30 MB each (6 GB total) typically compresses to 50-200 MB as M4V at the "Very High" preset with no visible quality loss to the eye. That's the point of converting: archive in TIFF, distribute in M4V.
Yes for both, with one caveat. Modern Windows ships H.264 decode in the OS since Windows 7, and Android since 3.0 (2011) — so the file plays in VLC, MX Player, Movies & TV, and Chrome / Firefox / Edge without extra installs. The .m4v extension itself isn't auto-associated with a player on Windows the way .mp4 is, so users may need to right-click → Open With → Movies & TV the first time, or rename to .mp4 (the bytes are identical when there's no FairPlay DRM).
No fixed per-file cap and no batch quantity limit. Conversion runs on our servers, so the practical limit is upload size and connection speed and how long you're willing to wait for upload. Multi-thousand-frame VFX sequences (10-50 GB of TIFFs in aggregate) are handled by streaming through the converter in chunks. For everyday slideshow work — 20-200 photos — the whole job typically finishes in under a minute.
No. FairPlay DRM is only applied by Apple's iTunes Store / Apple TV+ to content they sell or rent. Files you create with XConvert are plain H.264-in-M4V, freely playable, shareable, editable, and re-importable. The .m4v extension just signals "this is intended for Apple playback" — it carries no copy protection unless Apple's own purchase pipeline injects it.
