Using azid.dll v1.8 (b825) by Midas AC3enc.dll v0.1 by Gerard Lantau & Dg ( ).
Are my switches wrong or is ac3 2.0 not supported (though it should be acording to )?

Quality: TV -> VHS-> DVD5 whit menu, on which the equipment was done is not known Format: DVD Video Video codec: MPEG2 Audio codec: AC3 Video: 8000 Kbps, 29. I'm not too sure about this, Dolby is 16bit and DTS is 16 or 24bit.ġ6bit maximum dynamic range is 96db where 24bit is 144db.I have trouble creating an AC3 2.0 from an AC3 5.1 (3_2).
But Dolby is affected by Dialog Normalization & Dynamic Range Compression which somehow it doesn't have the full dynamic that DTS has. I have read that in 5.1 audio, you have 5 full channels and 1 channel at 1/3 the bit rate of the full channels. That also follows that youll get better quality at a lower bitrate with AAC, but that doesnt really matter in your transcoding situation as youre not going from a lossless source to either AC3 or AAC. To your point though, AAC at the same bitrate provides better compression than AC3 or DTS. On my own comparison, Dolby core 640kbps is better than DTS core 1536kbps in term of compression efficiency. AC3 is nearly universal as a baseline for compatibility. īTW, The Fugitive DD audio is encoded as 640kbps. That's why Bluray force the manufacturer to have backward compatible stream output via spdif (DD core, DTS core) / analog 5.1 / hdmi lcpm.

Many AV receiver that time don't even have HDMI input for LPCM. I would say 99% of the AV Receiver doesn't support the new format (DD+, TruedHD, DTS-HD/MA). When HD-DVD and Bluray finalise their draft.
It makes you wonder why they don't use DD+ if they're not able to put a HD audio codec on Blu-rays (for example, The Fugitive with its glorious 448kb/sec AC3 track).Ĭorrect me if I'm wrong. < 01:23:33> START PROCESS <> < 01:23:33> PROJECT SETTINGS DVD Video Standard: NTSC DVD Titles number: 1 DVD Size: 4450/4450 MB (100) DVD Output Setup: DVD Folder DVD Label: DEATHRACE2 DVD Menu: No Menu Output Folder: E:\DVD-TEMP Delete Temp Process Files: Yes Delete Working Files: Yes Edit Command Parameters: No Post Process Task: Show Progress Status window PREFERENCES.
