Best Settings for Quality Output in ImTOO DVD to WMV ConverterConverting DVDs to WMV with ImTOO DVD to WMV Converter can give you a compact, Windows-friendly video file while retaining much of the original DVD’s visual and audio quality. This guide walks through the best settings and practical tips to maximize output quality while balancing file size and compatibility.
1. Source material and preparation
Before adjusting converter settings, start with good source material and simple preparation steps:
- Inspect the DVD for scratches or read errors; a clean disc reads more reliably and reduces conversion artifacts.
- If the DVD contains multiple audio tracks or subtitles, decide which you need and remove extras to simplify encoding.
- Use the latest version of ImTOO to benefit from codec and bug fixes.
2. Choosing the right profile
ImTOO provides built-in profiles for WMV. For best quality:
- Start with a high-quality profile like “WMV9 – High Quality” if available.
- If you plan further editing, choose a profile with a higher bitrate and less compression.
3. Video codec and resolution
WMV supports several codecs (WMV8, WMV9, VC-1). For quality:
- Choose WMV9 (VC-1) when available — it offers better compression efficiency and visual quality than older WMV codecs.
- Keep the resolution the same as the DVD source (typically 720×480 for NTSC or 720×576 for PAL) to avoid resampling artifacts. Only downscale if you need smaller files for specific devices.
- If the target device requires 16:9, set aspect ratio conversion carefully: use a constrained resize (preserve aspect ratio) rather than stretching.
4. Bitrate and quality settings
Bitrate is the primary determinant of visual quality for lossy codecs.
- Use a two-pass VBR (variable bitrate) encoding if available. Two-pass yields better overall quality at a target size because it allocates bitrate where it’s needed.
- Aim for a target video bitrate in the range of 1500–3000 kbps for good-quality WMV from DVD at standard resolution. Increase toward 3000 kbps for scenes with a lot of motion or fine detail; decrease toward 1500 kbps when file size is a priority.
- If using constant bitrate (CBR), choose a higher bitrate (2500–4000 kbps) to avoid visible compression on complex scenes.
5. Frame rate and deinterlacing
DVD video is often interlaced; leaving interlaced video encoded as-is will produce combing when played on progressive displays:
- If the DVD is interlaced (common), enable deinterlacing to convert to progressive frames. Use high-quality deinterlace options (e.g., blend or bob with motion compensation) if offered.
- Keep the original frame rate (usually 29.97 fps NTSC or 25 fps PAL) unless you have a specific reason to change it. Converting frame rates can introduce judder.
6. Audio settings
High-quality audio preserves clarity without large file size increases.
- Use WMA (Windows Media Audio) codec at 192–256 kbps for stereo tracks for near-transparent audio. For multichannel (5.1) keep codec/bitrate consistent with target playback system.
- Choose 48 kHz sample rate to match DVD audio, or 44.1 kHz if you prefer compatibility with some players. Keep sample rate unchanged if possible to avoid resampling artifacts.
- If you are converting dialogue-heavy content and file size matters, 128–160 kbps can be acceptable.
7. Subtitle and chapter handling
Preserve or burn-in subtitles as needed:
- If you want selectable subtitles in the resulting WMV, include subtitle streams if the converter supports embedding them. Note: WMV has limited support for soft subtitles; embedding may not work across all players.
- For universal compatibility, burn-in subtitles (hardcode) onto the video. Use a high-contrast font and position subtitles to avoid covering important video content.
- Preserve chapters where possible; chapters make navigation easier in long conversions.
8. Filters and post-processing
Use filters judiciously — excessive sharpening or noise reduction can harm perceived quality.
- Apply noise reduction only if the source has visible video noise (e.g., old home movies). Moderate settings are preferable.
- Use sharpening sparingly; too much creates halo artifacts.
- Avoid multiple resizings or color-space conversions during the workflow.
9. Test and iterate
Always run short test encodes:
- Encode a 1–3 minute clip containing a mix of dialogue, motion, and dark scenes to evaluate quality and bitrate adequacy.
- Compare output on the target playback device (TV, phone, PC) to ensure deinterlacing and audio behave as expected.
- Tweak bitrate, deinterlacing, and audio settings based on the test.
10. Advanced tips
- If file size is critical, try two-pass VBR plus a slightly lower target bitrate while monitoring test results.
- For archival-quality copies, consider keeping MPEG-2 files or using lossless formats instead of WMV; WMV is for distribution/playback rather than pristine archival.
- Use GPU acceleration only if it produces comparable visual quality — hardware encoders can be faster but sometimes reduce quality at similar bitrates.
Summary checklist
- Use WMV9/VC-1 codec.
- Keep native DVD resolution (720×480 or 720×576).
- Use two-pass VBR with target video bitrate ~1500–3000 kbps.
- Enable deinterlacing for interlaced DVDs.
- Set audio to WMA 192–256 kbps, keep sample rate at 48 kHz if possible.
- Test with short clips and adjust.
