How to Use SVCDbuilder — Step‑by‑Step Tutorial for BeginnersSuper Video CD (SVCD) was a popular format for distributing video on CDs before DVDs became ubiquitous. SVCDbuilder is a tool that helps you create SVCD discs from video files. This tutorial walks you through everything a beginner needs: preparing source files, installing required tools, encoding video and audio, building menus (if desired), authoring the disc, burning, and troubleshooting common problems.
What is SVCD and SVCDbuilder?
SVCD (Super Video CD) stores MPEG-2 video and MPEG-1 Layer II audio on standard CDs. It offers better quality than VCD but lower capacity than DVD. SVCDbuilder is a collection of scripts and utilities (or a GUI wrapper, depending on the distribution) that automates the steps required to convert video files into a standards-compliant SVCD image and burn it to a CD.
Quick fact: SVCD uses MPEG-2 video and MPEG-1 audio with specific resolution and bitrate limits.
Before you start — system requirements and tools
You’ll need:
- A computer with a CD writer (or an external burner).
- Blank CD-R discs (700 MB) or CD-RW.
- Sufficient disk space (intermediate files can require several GB).
- The SVCDbuilder package (or a GUI front-end).
- Third-party tools commonly used in the process: FFmpeg (or MEncoder), spumux or PGCD authoring tools, PgcEdit or VobBlanker (optional), and a CD-burning utility (cdrecord/wodim, ImgBurn, Brasero, etc.).
Note: Specific package names and installation steps vary by OS. On Linux, many steps can be done with command-line utilities; on Windows, a GUI front-end may package required tools.
Step 1 — Prepare your source video
- Choose a source video file: MP4, AVI, MKV, or other common formats.
- Check source properties with FFmpeg:
ffmpeg -i input.mp4 - Decide target duration, whether to crop/resize, and whether to retain subtitles.
Tips:
- For SVCD, 480×480 (NTSC) or 480×576 (PAL) are typical resolutions. If your source is widescreen, you can letterbox or resize with padding to preserve aspect ratio.
- Keep target bitrates reasonable — SVCD has practical limits (usually max video bitrate ~2500 kbps combined with audio).
Step 2 — Transcode video to MPEG-2
SVCD requires MPEG-2 video with certain codec parameters. Use FFmpeg or MEncoder to transcode.
Example FFmpeg command (NTSC 480×480, 29.97 fps):
ffmpeg -i input.mp4 -target svcd -b:v 2200k -minrate 2200k -maxrate 2200k -vf "scale=480:480,setsar=1" -r 29.97 -g 15 -bf 0 -an output.m2v - -target svcd applies typical SVCD container/format settings.
- Adjust -b:v to control quality (higher bitrate = better quality but shorter total time).
If using PAL (25 fps, 480×576):
ffmpeg -i input.mp4 -target svcd -b:v 2200k -vf "scale=480:576,setsar=1" -r 25 -g 12 -bf 0 -an output.m2v Important:
- Produce a raw MPEG-2 stream (.m2v) for the video. Do not include audio in this file.
Step 3 — Encode audio to MPEG-1 Layer II
SVCD commonly uses MPEG-1 Layer II audio (.mp2). Use FFmpeg:
ffmpeg -i input.mp4 -vn -c:a mp2 -b:a 224k output.mp2 - Typical audio bitrates for SVCD: 224 kbps stereo. For speech-only content you can use lower bitrates (128–192 kbps).
If starting from separate audio or needing resampling:
ffmpeg -i input.wav -ar 48000 -ac 2 -c:a mp2 -b:a 224k output.mp2 Step 4 — Multiplex audio and video (muxing)
Combine the .m2v and .mp2 into an MPEG program stream (.mpg) suitable for SVCD. FFmpeg can mux:
ffmpeg -i output.m2v -i output.mp2 -c copy -f mpeg output.mpg Or use spumux/other muxers if you plan to add subtitles or need stricter standard compliance.
Check the final file with:
ffmpeg -i output.mpg Confirm the container is MPEG-PS with MPEG-2 video and MP2 audio.
Step 5 — Authoring the SVCD (creating disc structure)
SVCDs require an appropriate disc layout and optionally menus.
Basic authoring with svcdtools/spumux (example workflows differ by package):
- Use a tool (svcdimager, cdrdao, or specialized GUIs) to create the CD image with the correct directory structure (MPEGAV, SEGMENT, etc.) and an ISO image.
- If you want menus or chapters, use an authoring GUI (if available) or create PGCs via tools like spumux + pgcedit.
A simplified command (conceptual; adjust for your tools):
- Create an image:
mkisofs -V "SVCD_TITLE" -o svcd.iso -R -J <svcd-authoring-directory> - For strict SVCD standard compliance, use an SVCD-aware authoring tool to arrange files and create the correct CUE/TOC.
Note: Many beginners use GUI programs that wrap these steps and ensure compliance; if you’re unsure, choose a front-end that supports SVCD output (older authoring suites).
Step 6 — Burn the ISO to CD
Once you have svcd.iso and a cue/bin or appropriate image:
- On Windows: use ImgBurn or CDBurnerXP.
- On macOS: use Disk Utility or Terminal: hdiutil burn svcd.iso
- On Linux: use wodim or Brasero:
wodim -v dev=/dev/cdrw -data svcd.iso
Burn at moderate speed (e.g., 8x or lower) for best compatibility with standalone players.
Step 7 — Test the disc
- Test in multiple players: a software player (VLC) and a standalone SVCD player (if available).
- Check video playback, audio sync, menus, chapter points, and compatibility.
If playback fails:
- Re-check video/audio formats and bitrates.
- Verify disc was finalized (closed) so players can read it.
- Try burning at lower speed or use a different brand of CD.
Common issues and fixes
- Audio/video out of sync: ensure identical start times when muxing; re-encode ensuring same timestamps or use FFmpeg options to align streams.
- Incompatible resolution or framerate: confirm NTSC vs PAL settings and scale accordingly.
- Authoring errors: use an SVCD-aware authoring tool or a GUI that includes validation.
- Too much video for CD capacity: reduce bitrate or split content across multiple discs.
Tips for better quality and compatibility
- Use constant bitrate (CBR) or appropriately constrained VBR to stay within SVCD limits.
- For widescreen, letterbox rather than stretch; maintain aspect ratio when scaling to 480×480/480×576.
- Aim for combined video+audio bitrate under the CD MPEG-PS practical limits so the file fits a 700 MB disc.
- Keep a small test disc before committing multiple copies.
Alternatives to SVCD
If your goal is simple video playback, consider more modern options:
- Burn a standard data DVD (if you have a DVD burner) and store MP4 files playable by many players.
- Use USB drives or streaming for modern devices.
