Best Settings for TDMore DVD Copy to Preserve QualityPreserving the original quality of a DVD while copying can be tricky: you want the resulting disc or ISO to look and sound as close to the original as possible while still fitting the target media and remaining compatible with players. TDMore DVD Copy is a popular consumer tool for DVD backup that offers multiple modes and configuration options. This guide walks through the best settings and practical tips to maximize visual and audio fidelity when using TDMore DVD Copy.
1. Choose the Right Copy Mode
TDMore DVD Copy typically offers several copy modes. Pick the one that prioritizes quality:
- Full Disc: Best for preserving everything (menus, multiple audio/subtitle tracks, extras). It makes a complete 1:1 copy of the disc structure and therefore retains the original quality.
- Main Movie: Best for quality when you only need the primary video. It strips menus and extras but keeps the main title at original bitrate/resolution when possible.
- Clone or 1:1 Copy (if available): Ideal for perfect preservation because it duplicates the DVD bit-for-bit with no re-encoding.
Recommendation: Use Clone/1:1 if your goal is exact quality retention. If size or speed is a concern but you still want quality, use Full Disc. Use Main Movie only if you need to save space and don’t need extras.
2. Avoid Unnecessary Re-encoding
Re-encoding can degrade quality. TDMore may re-encode when converting to a different format or target size.
- If your target is a DVD-9 and the source is DVD-9: choose a mode that performs no re-encoding (Clone/1:1).
- If compressing from DVD-9 to DVD-5, expect some re-encoding. Minimize quality loss by using the highest-quality compression settings and a slower/advanced encoder if offered.
Recommendation: Prefer modes that maintain original stream copies. Only allow re-encoding when necessary (e.g., DVD-9→DVD-5).
3. Set Output Format and Disc Type Correctly
- Match the target disc type to the source: if you have a dual-layer original, burn to DVD-9 to avoid compression artifacts.
- If you must compress to DVD-5, set output to VOB/DVD-Video rather than a lossy container like MP4, unless you plan to playback on devices that require MP4.
Recommendation: Use DVD-Video (VOB/IFO/BUP) for disc compatibility and optimal DVD player playback.
4. Video Bitrate and Quality Options
When TDMore allows manual bitrate or quality presets, adjust carefully:
- If re-encoding, choose a high constant quality/preset (or high bitrate) to reduce visible artifacts.
- If given an average bitrate option, compute a target that balances size and quality. For DVD-5 (4.7GB) with a 2-hour movie, aim for a combined video+audio bitrate around 5,000–6,000 kbps for good quality; increase if the runtime is shorter.
Quick calculation (approximate):
- DVD-5 usable size ~4.37 GB (4,700,000,000 bytes minus file system overhead).
- For a 120-minute movie, 5,000 kbps ≈ 37.5 Mbps-minutes — TDMore may display size estimations; match bitrate to target size.
Recommendation: When compressing, set video bitrate high (or choose a “High” quality preset) and use 2-pass encoding if available.
5. Audio Settings
Audio quality matters and is less forgiving when downmixed or compressed.
- Keep original audio streams (AC3/DTS) where possible.
- If re-encoding audio, choose high bitrate AC3 (192–384 kbps) or uncompressed PCM if the disc space allows.
- Preserve multiple audio tracks if you want original language and commentary.
Recommendation: Keep original audio unchanged. If re-encoding, prefer AC3 at ≥192 kbps.
6. Subtitle & Extras Handling
Subtitles and extras don’t affect video quality but influence the output size.
- Remove unnecessary subtitle tracks to save space for higher video bitrates.
- If preserving extras, expect reduced bitrate for the main feature unless burning to a larger disc.
Recommendation: Remove unused extras/subtitles when compressing to DVD-5.
7. Use Two-Pass Encoding (If Available)
Two-pass encoding analyzes video in the first pass and optimizes bitrate allocation in the second. This reduces artifacts and improves detail retention compared to single-pass at the same average bitrate.
Recommendation: Enable 2-pass encoding when re-encoding and when time allows.
8. Choose the Right Burner and Media
Even with perfect settings, poor media or burner write strategies can affect playback.
- Use reputable blank media (Verbatim, Taiyo Yuden/other reliable brands).
- Burn at moderate speeds (e.g., 4x–8x) for best compatibility and fewer write errors. Higher speeds increase the chance of burn errors and playback issues.
- Verify discs after burning if TDMore offers verification.
Recommendation: Burn at a moderate speed and verify the disc when possible.
9. Update TDMore and Firmware
- Use the latest TDMore DVD Copy version for improved encoders and bug fixes.
- Update your DVD burner firmware for compatibility and writing improvements.
Recommendation: Check for updates before major backups.
10. Practical Workflows
- Exact backup: choose Clone/1:1 → burn to DVD-9 or create an ISO.
- Space-limited backup: Full Disc or Main Movie → remove unnecessary extras → enable 2-pass encoding → choose high video bitrate → keep original audio.
- Multiple-language discs: keep only the needed audio tracks and subtitles to preserve video bitrate.
Troubleshooting Common Quality Issues
- Blockiness/artefacts after compressing: increase bitrate, enable 2-pass, remove extra tracks.
- Audio sync issues: try remuxing without re-encoding audio; if re-encoding, ensure correct sample rate and codec.
- Playability problems: burn at lower speed, use DVD-Video output format, verify disc compatibility.
Quick Checklist (for best quality)
- Use Clone/1:1 when possible.
- If compressing: Full Disc or Main Movie with original audio removed only if necessary.
- Enable 2-pass encoding.
- Set high video bitrate or quality preset.
- Keep original audio or use ≥192 kbps AC3.
- Remove unneeded subtitles/extras.
- Burn on high-quality media at moderate speed.
- Update software and firmware.
Preserving DVD quality is mostly about avoiding unnecessary re-encoding, keeping original streams when possible, and allocating enough bitrate when compression is needed. Using TDMore DVD Copy with the settings above will give you the best chance of retaining the visual and audio fidelity of your DVDs.
