I pick up again and continue another thread on this topic started a year ago: https://www.mail-archive.com/[email protected]/msg02145.html In this post I start carefully with three questions regarding manual definitions and procedure in this section: https://cinelerra-gg.org/download/CinelerraGG_Manual/HDV_on_Blu_ray_Disc_Wit...
An MTS file is a video file saved in the high-definition (HD) MPEG Transport Stream video format, commonly called AVCHD. It contains HD video compatible with Blu-ray disc format and is based on the MPEG-2 transport stream. MTS files are often used by Sony, Panasonic, Canon and other HD camcorders.
========== Q1. My HDV 1080i video file transfered from tape to HDD via Firewire, get a file extension M2T, which then is recognized as format MPEG-TS by Mediainfo. AFAIK the next generation camcorders after HDV used H.264/AVC (AVCHD)? =========
Legal input for Video – MPEG1VIDEO, MPEG2VIDEO, H264; Audio – MP1, MP2, AC3, AC3PLUS, DTS, TRUHD.
To verify this with FFMpeg for the previous HDV test-file "20081103140154.m2t" available on internet: ffmpeg -i 20081103140154.m2t 2>&1 >/dev/null | egrep "Audio|Video" Stream #0:0[0x810]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt709, top first), 1440x1080 [SAR 4:3 DAR 16:9], 25000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x814]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s According to the manual, both the HDV MPEG2Video stream and MP2 audio stream should be legal input to create a Blu-ray disc. However, MP2 isn't on Sony's list or other I have seen over audio and video codecs supported on Blu-ray Disc media. https://www.sony.com/electronics/support/articles/00029663 Q2. Can someone clarify if MP2 rather should be transcoded to i.e AC3 instead, possibly also remux to BDAV/M2TS if required (below)? (On my first attempt with "MTS" format, Mediainfo reported this FileExtension_Invalid: ts m2t m2s m4t m4s tmf ts tp trp ty) ========= Q3. I also wonder if the manual command procedure creates a BDAV or a BDM structure, and optional if a DVD-RW disc can be used to create and playback this "Blu-ray disc" using a Blu-ray burner and a standalone UHD-Blu-ray player device? (At the time I have no free BD-R/RE discs left) ========= Transcode to AC3 and remux to M2TS with FFMpeg if required: ffmpeg -i 20081103140154.m2t -acodec ac3 -vcodec copy 20081103140154.m2ts ffmpeg -i 20081103140154_m2t-ac3.m2ts 2>&1 >/dev/null | egrep "Audio|Video" .........
