Supports: XCF
XCF is GIMP's native project file (released December 1997, named after UC Berkeley's eXperimental Computing Facility). It preserves layers, channels, paths, transparency, guides, and color profile, but no video player or camcorder reads XCF directly. MTS is the file extension AVCHD camcorders write — H.264 video plus AC-3 audio inside an MPEG-2 Transport Stream — introduced by Sony and Panasonic in 2006 and still the dominant consumer HD camcorder format. Converting flattens your XCF artwork into AVCHD-compatible video so it can sit alongside camcorder footage on the same SD card, NLE timeline, or Blu-ray disc.
| Property | XCF | MTS |
|---|---|---|
| Type | Layered raster image (project file) | Video container (transport stream) |
| Origin | GIMP, 1997 | AVCHD, Sony + Panasonic, 2006 |
| Holds | Layers, channels, paths, masks, guides | H.264 video + AC-3 (or LPCM) audio |
| Compression | Run-length + optional zlib/gzip/bzip2/xz | Lossy H.264 video, lossy AC-3 audio |
| Plays in | GIMP, Krita, Photopea, Paint.NET (partial) | VLC, MPC-HC, PotPlayer, Sony Vegas, AVCHD camcorders, PS3, PS4 |
| Typical use | Editing source for artwork | HD camcorder recordings, AVCHD authoring |
| Max bitrate | n/a (lossless) | 24 Mbps (AVCHD 1.0) / 28 Mbps (AVCHD 2.0 1080p60) |
| File extension | .xcf | .mts on camcorder SD;.m2ts after import |
| Preset | Approx CRF | 1080p Bitrate | Use case |
|---|---|---|---|
| Very High (default) | ~18 | 18-24 Mbps | Camcorder-spec slides, Blu-ray authoring |
| High | ~21 | 12-16 Mbps | Title cards mixed with consumer footage |
| Medium | ~24 | 8-10 Mbps | Web preview, short demo loops |
| Low | ~28 | 4-6 Mbps | Email-sized clips, draft review |
| Lowest | ~32 | 1-3 Mbps | Smallest possible MTS for transfer |
Camcorders, Blu-ray authoring tools, and AVCHD NLE timelines need video, not stills. If you've designed a title card, intro slate, or end credit in GIMP and the rest of the project is AVCHD camcorder footage, dropping the XCF into the timeline as MTS keeps the codec, resolution, and bitrate consistent — no mixed-format flags, no re-encode at export.
They flatten. MTS is a video container — every frame is a single rasterized image with no layer information. The converter renders the XCF as GIMP would when exporting to PNG (composite of visible layers, masks applied), then encodes that flat image as the video frame. Keep the original XCF if you need to edit further.
Whatever you set under "Duration." Default is 5 seconds per frame. The dropdown ranges from 1/60 second (one frame at 60 fps) up to 10 seconds. For a Ken-Burns-style slideshow, 3-5 seconds per image is conventional; for a single static title card, set 5-10 seconds.
Only if the file matches the AVCHD spec the camcorder expects (1920x1080 or 1440x1080, 24 Mbps cap, AC-3 audio) and lives in the right folder structure on the SD card (/PRIVATE/AVCHD/BDMV/STREAM/ on most Sony/Panasonic models). Use the default "Very High" preset and 1080p resolution to stay inside spec. Even then, some camcorders refuse playback of files they didn't record themselves — test on the device before committing.
"Merge images" produces one MTS containing every XCF as a sequential frame — pick this for slideshows, intro/outro packages, or anything that needs to play as a continuous clip. "Video per image" emits one MTS per uploaded XCF — pick this when each image is its own deliverable (separate title cards, batch-processed lower-thirds, individual slates).
XCF stores one compressed image; MTS stores at least 24 frames per second of H.264 video plus an AC-3 audio track (silent, but the stream still consumes bits). Even a 5-second slide at 1080p Very High will land around 12-15 MB. To shrink, switch to "Target file size (%)" and set 50%, drop resolution to 720p, or pick the Low / Lowest preset.
Vegas Pro and Movie Studio parse AVCHD MTS natively, so a spec-compliant file drops onto the timeline directly. Slow scrubbing on long-GOP H.264 is normal — that's a property of AVCHD itself, not the converter. If your Vegas project is AVCHD throughout, the editor will smart-render at export and skip re-encoding the slides. See MTS to MP4 if you instead need a non-AVCHD edit.
Same payload, different wrapper metadata. MTS is what camcorders write to SD cards; M2TS is what appears after the import to a computer or Blu-ray disc, with extra timing metadata. Switching extensions on disk is not a valid conversion — use MTS to M2TS for the proper remux. xconvert outputs .mts here; rename or remux for Blu-ray BDMV authoring.
Yes — see XCF to MP4. Pick MP4 if the destination is web playback, social media, or a non-AVCHD NLE (Premiere, DaVinci Resolve, Final Cut). Pick MTS only when the workflow specifically requires AVCHD: camcorder SD cards, Sony Vegas AVCHD projects, or Blu-ray BDMV authoring.
