Supports: XCF
XCF (eXperimental Computing Facility) is GIMP's native project format — it preserves layers, channels, paths, guides, and selections, but no media player can open it. MPG wraps MPEG-1 or MPEG-2 video in a program stream and is the format required to author DVDs and to play on the long tail of legacy hardware that never moved to MP4/H.264. Converting XCF → MPG flattens GIMP designs into a slideshow video those devices can play.
| Property | XCF | MPG (MPEG-1 / MPEG-2) |
|---|---|---|
| Type | Layered raster image (project file) | Video container (program stream) |
| Codec | N/A — raw layer data with optional zlib/gzip/bzip2/xz compression | MPEG-1 Part 2 or H.262/MPEG-2 Part 2 video; MP2/AC-3/PCM audio |
| Created by | GIMP (also Krita, CinePaint, Photopea read partially) | Standardized by ISO/IEC; produced by ffmpeg, HandBrake, DVD authoring tools |
| Standardized | "Open" but ad hoc — GIMP devs discourage it for interchange | ISO/IEC 11172 (MPEG-1, 1993) and 13818 (MPEG-2, 1996) |
| Plays in media players | No (image editor only) | Yes — VLC, MPC-HC, Windows Media Player, set-top DVD players |
| Typical use | Active GIMP edit, layered source | DVD-Video, broadcast, legacy playback |
| Transparency | Yes (per-layer alpha) | No (flattened, opaque frames; letterbox via background color) |
| File size for a 1-min slideshow | Often 50-200 MB raw | ~50-75 MB at DVD bitrate (8 Mbps), much smaller at lower CRF |
| Target | Codec | Resolution | Bitrate | Notes |
|---|---|---|---|---|
| DVD-Video (NTSC) | MPEG-2 | 720×480 @ 29.97 fps | 6-8 Mbps CBR + AC-3 audio | Required by the DVD-Video spec; cap is 9.8 Mbps video |
| DVD-Video (PAL) | MPEG-2 | 720×576 @ 25 fps | 6-8 Mbps CBR + AC-3 audio | Same spec, European/Asian region |
| VCD (legacy) | MPEG-1 | 352×240 (NTSC) / 352×288 (PAL) | 1.15 Mbps CBR + 224 kbps MP2 | For VCD authoring; very old players only |
| SVCD (legacy) | MPEG-2 | 480×480 (NTSC) / 480×576 (PAL) | 2.5 Mbps VBR + MP2 | Mid-quality CD-based video |
| General MPG playback | MPEG-2 | 1920×1080 @ 30 fps | 8-15 Mbps VBR | Modern HD MPEG-2 (used by ATSC broadcast) |
| Low-bandwidth share | MPEG-2 | 854×480 @ 30 fps | 2-4 Mbps VBR | Smaller file for email or chat upload |
They're the same thing. The.mpg extension was adopted because some pre-Windows 2000 systems required three-character extensions;.mpeg is the longer, identical alternative. Both typically wrap MPEG-1 Part 2 or MPEG-2 Part 2 (a.k.a. H.262) video in an MPEG program stream. There's no quality, codec, or compatibility difference — just the filename.
Compatibility with old hardware. MP4 with H.264 produces files roughly 30-50% smaller than MPEG-2 at equivalent quality and is the modern default. But DVD players, car DVD systems, and 2005-era set-top boxes never got H.264 decoders — they only speak MPEG-2 program streams. If your target device is one of those, MPG is the right answer. Otherwise, XCF to MP4 is faster, smaller, and more compatible with phones, browsers, and modern editors.
No. MPG is a video stream, not a layered image format. Each XCF is flattened (layers composited top-to-bottom, applying their blend modes and opacities) before being encoded as a video frame. If you need to keep layers, export the XCF as PSD or keep the original.xcf — see XCF to PNG for a flattened still image instead.
Default is 5 seconds, which works for most slideshow viewers (long enough to read a caption, short enough to keep momentum). Use 1-2 seconds for fast montages or motion-tween-style sequences, 8-10 seconds when each frame has substantial text. For animation built from XCF frames in 1/24-second or 1/30-second steps, the converter treats the XCF stack as a frame sequence at that frame rate.
720×480 at 29.97 fps for NTSC (North America, Japan), 720×576 at 25 fps for PAL (most of Europe, Australia, Asia, South America). Pick the preset matching the player's region. Other sizes (704×480, 352×480) are valid in the DVD-Video spec but unusual today. If you'll just play in VLC or upload to a website, native dimensions or 1920×1080 give a sharper result than DVD's 480-line cap.
6-8 Mbps Constant Bitrate using MPEG-2. The DVD-Video spec caps total bitrate at 10.08 Mbit/s including audio and subtitles, with video alone capped at 9.8 Mbit/s. Going below 4 Mbps shows visible blocking on smooth gradients (which XCF designs frequently contain); 8 Mbps gives an hour of slideshow per DVD-5 disc with headroom. Use Variable Bitrate when the target file size matters more than per-frame quality.
It doesn't. Video frames have no alpha channel, so any transparent pixels in the XCF render against the background color set under "Background Color" (default black). To preserve a logo's transparent halo, either set a matching background color, or composite the XCF over a real background image in GIMP first, then convert.
The converter renders MPG without an audio track (slideshow video only). To add narration or music, import the resulting MPG into a video editor (DaVinci Resolve, Shotcut, OpenShot, or DVDStyler for disc projects) and lay the audio underneath. DVD authoring tools mux the audio onto the program stream during disc compilation.
MPEG-2 is roughly 30 years old and lacks the prediction/transform tools H.264 uses. A 10-minute 1080p slideshow at DVD-comparable visual quality is typically 600-900 MB as MPG vs 150-250 MB as MP4. That size cost is the price of legacy compatibility — unavoidable when targeting MPEG-2-only hardware.
