AEPvideo DVD COPY — Step‑by‑Step Guide to Perfect Digital Backups

AEPvideo DVD COPY — Best Settings for Quality Preservation

Recommended workflow (preserve max quality)

1. Source: Use the original DVD disc or ISO; avoid recompressing already-ripped files when possible.
2. Mode: Choose “Full Disc” or “Main Movie (No Re-encode)” if AEPvideo offers a lossless copy/ISO option. If only re-encode is available, use a high-bitrate or near-lossless preset.
3. Container: Prefer MPEG-2 DVD structure for direct DVD backups; choose MKV or MP4 only if you intend to reencode for file playback.
4. Video codec & bitrate:
   • If keeping DVD format: keep original MPEG-2; do not transcode.
   • If converting: use H.264 (x264) or HEVC (H.265) with constant quality (CRF) targeting visually lossless: CRF ≈ 16–18 for x264, CRF ≈ 20–22 for x265. Alternatively set high average bitrate (e.g., 5–8 Mbps for 480p DVD source) if encoder uses ABR/VBR.
5. Encoder preset: Use a slow/veryslow preset for best quality (sacrifice speed).
6. Frame rate & resolution: Preserve source frame rate and native resolution (⁄₅₇₆). Do not upscale.
7. Audio: Use passthrough for original AC-3/DTS when keeping DVD structure. If reencoding, use AAC or AC-3 at 192–384 kbps (or keep original bitrate).
8. Subtitles & menus: Include original subtitle streams; preserve menus if making a DVD ISO.
9. Filters: Disable sharpening or denoise unless source needs correction; use modest deinterlace only if source shows interlace artifacts.
10. Two-pass encoding: Use two-pass VBR for bitrate-target workflows when file size matters; otherwise CRF is preferred for quality.
11. Hardware acceleration: Avoid hardware encoders (QuickSync, NVENC) for final archival copies — they’re faster but can reduce quality vs. CPU encoders at same bitrate. Use hardware only for quick copies.
12. Verification: After copy, compare a short visually busy clip from source vs. output to confirm preservation; store an untouched ISO or MakeMKV/VIDEO_TS rip for long-term archival if possible.

Quick presets (practical choices)

• Lossless backup (best): Full disc copy → ISO or VIDEO_TS (no re-encode)
• Archive file (high quality, smaller): x264, CRF 16, veryslow, preserve source FPS/res, AAC 256 kbps (or AC-3 passthrough)
• Compatible, smaller (good): x265, CRF 22, slow, preserve FPS/res, AAC 192 kbps

If you want, I can convert these into exact AEPvideo DVD COPY menu choices assuming the app exposes codec, CRF, preset, and bitrate fields.
