Supports: WEBP
WebP is Google's modern image format (launched 2010, full browser support reached in 2020 when Safari 14 added it), excellent for the web but unplayable on legacy hardware that only speaks MPEG. MPG is the file extension for an MPEG-1 or MPEG-2 program stream defined in ISO/IEC 11172 and ISO/IEC 13818 — the same container that holds DVD-Video, Video CD, and Super Video CD content. Common reasons to convert WebP to MPG:
| Profile | Video codec | Resolution | Max video bitrate | Audio | Use case |
|---|---|---|---|---|---|
| VCD | MPEG-1 | 352x240 (NTSC) / 352x288 (PAL) | 1,150 kbps fixed | MP2, 44.1 kHz, 224 kbps | CD-burnable, ~74-80 min per disc |
| SVCD | MPEG-2 | 480x480 (NTSC) / 480x576 (PAL) | 2,600 kbps | MP2, 44.1 kHz, 32-384 kbps | Higher-quality CD playback |
| DVD-Video | MPEG-2 (MPEG-1 allowed) | 720x480 (NTSC) / 720x576 (PAL) | 9.8 Mbps | LPCM, MP2, AC-3 | Set-top DVD players |
| Generic.mpg | MPEG-1 or MPEG-2 | Up to 4095x4095 (MPEG-1) | Up to 100 Mbps (MPEG-1) | MP2 | PC playback, archival |
| Property | WebP | MPG |
|---|---|---|
| Media type | Image (with animation variant) | Video container (program stream) |
| Codec | VP8 (lossy) / VP8L (lossless) | MPEG-1 Part 2 or MPEG-2 Part 2 |
| Released | 2010 (Google) | 1993 (MPEG-1) / 1995 (MPEG-2) |
| Standard | RFC 9649 (IETF, 2024) | ISO/IEC 11172 / ISO/IEC 13818 |
| Audio | None | MP2 (Layer II), LPCM, AC-3 (DVD) |
| Browser playback | Chrome 32+, Firefox 65+, Safari 14+, Edge 18+ | Not natively in modern browsers; needs HTML5 video shim or download |
| Hardware decode | Modern GPUs / phones | Built into every DVD player, many older TVs |
| Typical use | Web images, animated stickers | DVD / VCD / SVCD authoring, legacy playback |
That depends on the Merge strategy. "Merge images" stitches every uploaded WebP into a single MPG slideshow in upload order (use file names like 01_intro.webp, 02_photo.webp to control sequence). "Video per image" produces one short MPG per WebP — useful when you need each image as a standalone clip for editing.
The Image Duration setting applies to each uploaded file as a still — animated WebPs are typically rendered as their first frame at the chosen duration, not unpacked frame-by-frame at the source rate. If you need the WebP animation timeline preserved, convert to MP4 or GIF first via WebP to MP4 or WebP to GIF, then re-encode to MPG.
For a DVD-Video-compatible disc, use 720x480 at 29.97 fps (NTSC, North America / Japan) or 720x576 at 25 fps (PAL, Europe / most of the rest). For a VCD, drop to 352x240 NTSC / 352x288 PAL. For Super Video CD, use 480x480 NTSC / 480x576 PAL. Picking the wrong region (NTSC where the player expects PAL) is the most common reason discs fail to play.
The default of 5 seconds per frame is good for most photo slideshows — long enough to read captions, short enough to keep momentum. Reduce to 2-3 seconds for a fast-paced reel, raise to 7-10 seconds when accompanying audio narration. For a 60-image set at 5 seconds each, expect a 5-minute output.
WebP is one of the most efficient image codecs in use — for a typical photo, a WebP can be 25-50% smaller than the same JPEG. MPG (especially MPEG-1) is a much older video codec with weaker compression, and the output now stores the same image redundantly across 30 frames per second of holding time. A 100 KB WebP held for 5 seconds at NTSC bitrate produces roughly 720 KB of MPEG video — that's expected, not a bug.
Not by default — the converter generates a silent video track. To add a soundtrack, convert to MPG first, then use a video editor (Shotcut, DaVinci Resolve, Premiere) to mux in an MP2, AC-3, or LPCM audio track that matches the chosen profile (MP2 for VCD/SVCD, AC-3 for DVD).
The MPG file is the video portion. To make a playable disc, you still need an authoring step: ImgBurn, DVD Flick, or DVDStyler for DVD-Video; VCDImager or cdrtools for VCD/SVCD. These tools take the MPG, add the disc filesystem (UDF for DVD, ISO 9660 / CD-i Bridge for VCD/SVCD), and burn the result. Pick the matching profile in the converter so the MPG already meets the disc spec.
Yes — see Compress MPG to reduce bitrate, drop resolution, or trim duration. A standard 700 MB CD-R holds ~80 minutes at VCD bitrate or ~35 minutes at SVCD bitrate; a 4.7 GB DVD-R holds ~120 minutes at typical DVD-Video bitrate.
MPG is an MPEG program stream — older, simpler, designed for fixed-rate playback off optical discs. MP4 (ISO/IEC 14496-14) and MOV (Apple QuickTime) are newer ISO Base Media containers that wrap H.264/H.265 video, AAC audio, subtitles, chapters, and metadata. For modern playback on phones, TVs, and the web, MP4 wins on size and compatibility. MPG is the right pick only when targeting legacy hardware or authoring a VCD/SVCD/DVD-compatible disc.
