.m2ts Blu-ray transport stream downloads on our servers — no sign-up, no watermark.TIFF is the archival workhorse of photography and print — uncompressed or losslessly compressed, 16-bit-per-channel, and trusted by museums and prepress shops since Aldus shipped the spec in 1986. M2TS is the opposite end of the pipeline: a 192-byte-packet variant of MPEG-2 Transport Stream that Blu-ray players read directly from the BDMV/STREAM/ directory (Wikipedia,.m2ts). Turning a stack of TIFFs into M2TS lets you author a photo slideshow that plays on a standalone Blu-ray deck, a Sony PlayStation 4/5, or AVCHD-aware camcorder firmware without re-encoding.
.MTS files inside AVCHD/BDMV/STREAM/. Convert your TIFF intro/outro plates to the same H.264 + AC-3 envelope and they slot in cleanly when re-authoring the card..mts/.m2ts files.| Property | TIFF | M2TS |
|---|---|---|
| Media type | Still image (single or multi-page) | Video container (transport stream) |
| Container basis | Custom IFD tag-based format | MPEG-2 TS with 192-byte packets (188 + 4-byte timestamp header) |
| Typical codecs | Uncompressed, LZW, ZIP/Deflate, PackBits, JPEG, ZSTD | Video: H.262, H.264/AVC, SMPTE VC-1; Audio: Dolby Digital (AC-3), DTS, LPCM |
| Color depth | 1 / 8 / 16 / 32 bits per channel | 8-bit (10-bit only via UHD Blu-ray profiles) |
| Max resolution | Effectively unlimited (gigapixel-class scans) | 1920x1080 for Blu-ray BDMV; 3840x2160 for UHD Blu-ray |
| Audio | None | Mandatory in BDMV authoring |
| Player support | Photoshop, GIMP, Preview, archival viewers | Blu-ray players, PS4/5, VLC, MPC-HC, MPlayer, PotPlayer |
| Primary use | Archival photography, prepress, GIS | Blu-ray Disc playback, AVCHD camcorders, broadcast-style streaming |
| Setting | When to pick it |
|---|---|
| Video codec defaults to H.264 (AVC) | Universally supported by every Blu-ray player shipped since 2006 — leave this alone unless your authoring tool specifically demands MPEG-2. |
| Quality Preset — Very High (Recommended) | Best match for TIFF-quality input. Keeps gradients and fine print detail intact at the cost of larger files. |
| Quality Preset — High / Medium | Good for kiosk loops or USB playback where shelf size matters more than absolute fidelity. |
| Constant Quality mode | Uses a fixed CRF target so every frame gets the bitrate it needs — pick this for stills with varied complexity. |
| Constraint Quality mode | Caps the bitrate ceiling so the file stays inside Blu-ray's bitrate budget (typically 40 Mbps for BD video). |
| Image Duration — 5 seconds (default) | Standard slideshow pace; long enough to read captions but short enough to keep momentum. |
| Image Duration — 1/24 to 1/60 second | Use only if you're frame-packing a stop-motion sequence; durations under 1/24s require a frame-accurate authoring tool downstream. |
| Background Color — Black | Matches Blu-ray letterboxing convention; switch to White only for prints-on-paper aesthetics. |
The M2TS stream itself is spec-compliant H.264 + AC-3 audio inside a 192-byte-packet transport stream, which is what Blu-ray players parse. To make a player auto-load it from disc, you still need to wrap the file in the BDMV folder structure (BDMV/STREAM/00001.m2ts plus index.bdmv and clipinfo/playlist files). Tools like multiAVCHD, tsMuxeR, or DVDFab Blu-ray Creator handle that authoring step. If you just want USB playback, many recent Sony, Panasonic, and LG decks will play a bare .m2ts from a thumb drive.
MP4 is fine for software playback, but Blu-ray hardware players are required to support transport streams (MPEG-TS) — they're not required to support MP4/MOV. M2TS also recovers more gracefully from corruption or mid-stream interruption because each 192-byte packet carries its own timestamp, which matters for kiosks, signage loops, and broadcast-style workflows. For pure web or phone playback, TIFF to MP4 is the smaller, more portable target.
Both are transport-stream containers with the same 192-byte packet structure. .mts is the file extension Panasonic and Sony AVCHD camcorders write to the SD card; .m2ts is the same payload renamed when it lands inside a Blu-ray BDMV/STREAM/ folder. Pick M2TS when authoring Blu-ray; pick TIFF to MTS when feeding files back into AVCHD camcorder card structures.
Stick with 1920x1080 (1080P) unless you specifically need UHD Blu-ray, in which case use 3840x2160 (2160P). Standard Blu-ray players reject non-spec resolutions — they will not play a 1366x768 or 2560x1440 M2TS. For TIFFs much larger than 1080p, downscaling to 1080p with a Very High quality preset preserves sharpness while staying inside the spec.
M2TS encodes opaque 4:2:0 video — there is no alpha channel. Any transparent pixels in your TIFF are composited against the Background Color you chose (Black by default). If your TIFF was saved with an alpha mask intended for compositing, flatten it in your editor against your preferred backdrop before uploading, or set Background Color to match your downstream key color.
Yes when "Merge images" is selected as the Merge strategy — every page of a multi-page TIFF becomes one frame held for the Image Duration you set, then the converter moves to the next page. With "Video per image" selected, each page becomes its own M2TS file. If you'd rather treat multi-page TIFFs differently, split them first with a TIFF-aware tool like ImageMagick's magick input.tif%d-out.tif.
The Blu-ray Disc spec caps video at 40 Mbps for the main feature stream (Wikipedia,.m2ts). When you pick Constraint Quality and Very High, the encoder stays well inside that ceiling for typical slideshow content. If you're seeing playback stutter on an older player, drop to High or set a manual bitrate cap around 25-30 Mbps.
This tool produces a silent M2TS from images alone. For an audio bed, run the M2TS plus your soundtrack through a mux step (tsMuxeR is free and BDMV-aware), or convert your image set to JPG to M2TS / Image to M2TS and pair the result with an AC-3 or DTS audio file in your Blu-ray authoring tool. Blu-ray mandates Dolby Digital, DTS, or LPCM for audio — MP3 audio is non-compliant.
A 5-megabyte LZW TIFF held for 5 seconds at 1080p H.264 is still 5 seconds of video — encoded at the bitrate the Very High preset chose. The static frame is highly compressible, but the transport-stream overhead (192-byte packets, PCR/PAT/PMT tables every ~40 ms) adds a floor of roughly 1-2 Mbps even on still imagery. Lowering Image Duration or switching to High instead of Very High noticeably reduces total size.
