Supports: MP4, M4V
5.250 for 5 seconds, 250 ms), or choose Multiple Screenshots and pick an interval from every 0.1 seconds up to every 10 seconds.M4V is Apple's video container — essentially MP4 with a different extension to signal iTunes content. It first shipped in 2006 alongside the iTunes Store and typically carries H.264 video with AAC or Dolby Digital audio. TIFF, published by Aldus in 1986 (Adobe acquired Aldus in 1994 and now maintains the spec), is the print and archival standard for raster imagery, supporting lossless compression, 16-bit-per-channel color, CMYK, alpha, and embedded ICC profiles. Extracting frames from M4V as TIFF gives you a print-ready still — no JPEG blocking, no chroma subsampling — that drops directly into a Photoshop or InDesign workflow.

Renaming .m4v to .mp4 plays? |
Yes if unprotected | n/a | No |
| Best for | Apple ecosystem distribution | Universal web/mobile | Editing (especially with ProRes) |
| Type | Lossless | Best Use | Notes |
|---|---|---|---|
| LZW | Yes | General purpose, default | Universal support since TIFF 6.0 (1992); can paradoxically grow 16-bit files |
| DEFLATE (ZIP) | Yes | 16-bit photography, archival | Same algorithm as PNG/zip; recommended for 16-bit |
| ZSTD | Yes | Modern archival, fastest decode | TIFF tag 50000; supported by libtiff 4.0.10+ but not in all readers |
| PACKBITS | Yes | Fast encoding, simple data | Small overhead; weaker ratio than LZW on photos |
| JPEG | No | Web-origin content | Chroma-subsampled; defeats the point of TIFF for most uses |
| NONE | Yes | Maximum compatibility | Largest file; safest for legacy or forensic pipelines |
Movies and TV shows purchased or rented from the iTunes Store or Apple TV app are wrapped in Apple's FairPlay DRM. The video stream is encrypted and tied to your Apple ID; no third-party converter — including this one — can decrypt it. FairPlay decryption happens inside Apple's authorized playback path. Home videos, screen recordings, and unprotected M4V files convert normally. If you renamed an unprotected .m4v to .mp4 and it played in VLC, this tool will accept it.
The bytes are identical — same file, same Adobe TIFF 6.0 spec. .tiff is the full extension; .tif is the legacy 3-character form from the DOS era. Pick whichever matches your downstream tooling under "File extension." Photoshop, InDesign, GIMP, and ImageMagick read both without issue.
For 8-bit color, LZW and DEFLATE produce roughly comparable sizes and both are universally supported. For 16-bit color, prefer DEFLATE — LZW's dictionary approach often performs poorly on high-entropy 16-bit data and can produce larger files than uncompressed. ZSTD beats both on size and decode speed, but reader support is narrower (libtiff 4.0.10 from 2018 onward; some pro DAM and prepress tools still don't read it).
Yes. Choose Specific Frame and enter the time in seconds. Decimal values work — 5.25 captures the frame at 5 seconds, 250 milliseconds. For multiple stills at fixed intervals, switch to Multiple Screenshots and pick an interval from 0.1 seconds (10 fps sampling) up to every 10 seconds.
The M4V H.264 stream is 8-bit per channel in almost every consumer case (4:2:0 chroma subsampled). The TIFF output can be saved as 8-bit or 16-bit, but upsampling to 16-bit doesn't recover information that wasn't in the source — it only gives you headroom for downstream grading without banding. For 10-bit HDR content (rare in M4V), choose 16-bit DEFLATE.
xconvert's tier limits apply (see the homepage for the current free and paid caps). Practically, frame extraction is light on bandwidth — only the chosen frames are encoded as TIFF, so a 4K still is typically 20-50 MB at 16-bit DEFLATE and 8-15 MB at 8-bit LZW. The full M4V upload is the constraining factor.
Yes — set Multiple Screenshots to every 0.1 seconds for a roughly 10 fps sample, or use a smaller interval to approach the source frame rate (typical M4V is 23.976, 25, or 29.97 fps). For a true frame-perfect sequence, extract at the source rate and accept that some intervals may snap to the nearest decoded frame.
The xconvert pipeline writes RGB TIFFs by default — color-managed but not pre-separated. For CMYK output (common in offset print), open the TIFF in Photoshop and run Image → Mode → CMYK Color with your target ICC profile (e.g. GRACoL 2013, FOGRA51). TIFF supports embedded ICC profiles and CMYK natively, so the conversion is non-destructive at the format level.
PNG is also lossless 8/16-bit and works well for web, but lacks CMYK and the rich tag set print houses expect (resolution units, color separations, layers in some flavors). JPG is lossy — fine for web previews, wrong for print or archival. Need PNG or JPG instead? Use M4V to PNG or M4V to JPG. For onward TIFF processing, TIFF to JPG and Compress TIFF are useful follow-ups. To get a usable MP4 from your M4V first, see M4V to MP4.
