How to Use MultiAVCHD for Multi-Format Disc Authoring

MultiAVCHD Tips: Best Settings for Blu-ray, AVCHD & ISO Output

Choose Blu-ray vs AVCHD based on playback device: pick Blu-ray for standalone Blu-ray players and AVCHD for many HDTVs and PS3/PS4.
ISO vs folder: create an ISO when you plan to burn later or need a single-file image; use folders when testing on PC or copying to USB.

Use high-quality source files (preferably AVC/H.264 or lossless intermediate). Avoid heavily compressed originals if possible.
Match container/frame rates: set project to the source frame rate (e.g., 23.976, 29.97, 25) to avoid judder; convert only if target player requires a specific rate.

Resolution: 1920×1080 for Blu-ray; 1440×1080 or 1280×720 for AVCHD depending on source and device compatibility.
Long-GOP H.264 is standard—use encoder presets that balance quality and speed (slower = better quality).
Bitrate:
- For Blu-ray: target average bitrate ~18–24 Mbps for 1080p; cap at 25 Mbps (Blu-ray max VBR ~40 Mbps combined video+audio but safe per-stream range is lower).
- For AVCHD: 1080/60i or 1080/24p sources — aim ~12–18 Mbps; for 720p aim ~6–9 Mbps.
Two-pass VBR yields best quality/bitrate efficiency—use if time permits.
Profile & level: High profile, Level 4.1 for Blu-ray 1080p; ensure encoder adheres to profile restrictions (B-frames, ref frames).

Format: AC3 (Dolby Digital) is widely supported; LPCM is higher quality but uses more space.
Bitrate: 192–384 kbps for AC3 is typical; for LPCM choose ⁄₂₄-bit at 48 kHz.
Channel layout: Keep original channels (stereo vs 5.1); downmix only if target device lacks multichannel support.

Keep menus simple for compatibility and smaller project size. Complex scripted menus increase processing and potential issues.
Button sizes and positions: Ensure standard safe areas so players render correctly.
Test navigation on target players—some players handle certain menu features differently.

Use conservative encoder settings if you need broadest compatibility (lower bitrate, standard GOP sizes).
Check AVCHD version: AVCHD 2.0 supports 1080p60 on some devices—only use if confirmed compatible.
Region and disc format: Use BD-R for most burns; some older players prefer single-layer discs.

Avoid excessive subtitles/streams—they consume space and increase authoring complexity.
Keep total bitrate within disc/container limits (sum of video + audio + subtitles + menus). Use MultiAVCHD’s bitrate calculator to confirm.

Preview ISO in virtual drive and test on actual hardware where possible.
Check for playback artifacts (macroblocking, audio sync) and adjust bitrate/GOP accordingly.
Optimize project size: if exceeding target, reduce video bitrate or re-encode with stronger compression settings.

Use x264 encoder with tuned presets: slower presets (e.g., veryslow) improve quality per bitrate.
GPU acceleration: Helpful for speed but sometimes reduces compatibility—prefer CPU x264 for best standards compliance.
Batch encode: Encode all videos first, then author to minimize re-encoding.

Audio sync issues: recheck frame rates and remux using consistent timestamps.
Disc not recognized: burn at lower speed, finalize disc, try different media brand.
Menu freezes: simplify script, reduce background bitrate, or use static images.

If you want, I can suggest exact encoder command-line settings for x264/x265 for a specific source (resolution, frame rate, desired size).
