Best Settings for Ultra DVD Ripper: Preserve Quality and Reduce File Size
1. Choose the right output format
- MP4 (H.264): Best compatibility and good quality/size balance.
- HEVC (H.265): Smaller files at same quality—use if target devices support it.
- MKV: Use when you need multiple audio/subtitle tracks or lossless passthrough.
2. Video codec and bitrate
- Codec: H.264 for broad compatibility; H.265 for better compression.
- Bitrate mode: Use CRF (constant quality) if available.
- H.264 CRF: 18–22 (18 = very high quality, 22 = good size).
- H.265 CRF: 20–26 (use higher values for smaller files).
- If only bitrate is available, target:
- 720p: 1500–2500 kbps
- 1080p: 3500–6000 kbps
3. Resolution and frame rate
- Keep source resolution for best quality. Downscale to 720p to save size.
- Frame rate: Match source (usually 23.976, 25, or 29.97 fps). Avoid converting unless necessary.
4. Audio settings
- Codec: AAC (LC) for compatibility; Opus for modern devices.
- Bitrate: 128–192 kbps for stereo; 192–320 kbps for multichannel.
- Sample rate: Keep at source (usually 44.1 or 48 kHz).
5. Subtitle and audio track handling
- Burn subtitles only if target device lacks support.
- Include one or two essential audio/subtitle tracks and remove extras to save space.
6. Advanced options
- Two-pass encoding: Slightly better quality at a given bitrate (use if targetting fixed bitrate).
- Hardware acceleration (NVENC/QuickSync): Much faster; may be slightly larger or lower quality than CPU x264 at same bitrate—test and compare.
- Deinterlace/denoise: Apply only if source needs it; denoising reduces bitrate needs but can soften detail.
7. Practical presets (recommended)
- High quality, moderate size: MP4, H.264, CRF 20, keep resolution, AAC 192 kbps.
- Maximum compression: MP4, H.265, CRF 24, downscale to 720p, AAC 128 kbps.
- Compatibility-focused: MP4, H.264, CRF 22, keep resolution, AAC 192 kbps, include main subtitle.
8. Workflow tips
- Rip a short sample (5–10 minutes) with chosen settings and compare.
- Keep originals for future re-rips if standards improve.
- Batch process similar titles with the same settings for consistency.
9. Quick checklist before ripping
- Match frame rate and resolution to source when possible.
- Prefer CRF over fixed bitrate for quality presets.
- Remove unnecessary tracks and chapters.
- Test hardware acceleration vs CPU encoding for trade-offs.
Use these settings as starting points and adjust after test rips to match your quality/size preference.
