As known a Blu-ray player device need a standard Blu-ray disc directory structure (bdwrite) for playback, i.e
tree -h bd_20161216-153642
bd_20161216-153642 ├── [183M] bd.m2ts ├── [ 394] bd.sh ├── [191M] bd.udfs ├── [5.3K] bd.xml └── [4.0K] udfs
1 directory, 4 files
Possibly the above file tree structure on hdd isn't complete as on the BD .........(should include BDMV ...)
While DVD use MPEG-2, I cannot see MPEG-2 with high bitrate for SD DV (or HDV) on Blu-ray is possible?
well, you can try to create mpeg2 m2ts profile and temporarily replace usual h264-based ones.. if this experiment resulted in working BD disk - we probably can add checkbox or menu selecting specific codec. Just bitrate for mpeg2 must be much higher for same quality at given resolution (saw 40 mbit/s fullhd file) , and blu-ray has hard limit on bitrates it can handle (from memory: around 25 mbit/s) ..
I add some more info to this part: Re. BD-R bit rate https://en.wikipedia.org/wiki/Blu-ray#Bit_rate BD drive speeds/Data rate https://en.wikipedia.org/wiki/Blu-ray#Drive_speeds In comparison DV: 25 Mbps (compression 5:1) DVD max 9.8 Mbps (SD, MPEG-2/MP@ML) HDV 1080i: 25 Mbps (MPEG-2/MP@H-14) ------------- info of interest from Vegas Pro manual (2020): https://dl03.magix.com/manual_vegaspro18_en_eij3hp.pdf page 478: Media File Settings for Blu-ray Disc Projects You can burn Blu-ray Disc projects to BD recordable discs using the BDMV format: A 25 GB single-layer BD recordable disc can store approximately 3 hours, 42 minutes of AVC video (15 Mbps) or 2 hours, 15 minutes of MPEG-2 video (25 Mbps). A 50 GB dual-layer BD recordable disc can store approximately 7 hours, 25 minutes of AVC video (15 Mbps) or 4 hours, 31 minutes of MPEG-2 video (25 Mbps) page 459: You can store large amounts of standard-definition MPEG-2 video on a BD disc.
