<p>
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. Legal input for Video –
MPEG1VIDEO, MPEG2VIDEO, H264; Audio – MP1, MP2, AC3, AC3PLUS, DTS,
TRUHD.
</p><p>Note, mp2 and mp1 audio codecs are valid for transport stream itself but not as on-disk format for Blu-Rays.</p><p>In this case you still can save original video by using ffmpeg's switches</p><p> -c:v copy -c:a ac3 , while outputting into another temporal ts container.</p><p>{waiting for Terje's results on pcm_bluray case}</p><p><br></p><p>---</p><p><br></p><p>I think all m2ts files you used for testing were h264/aac (or ac3), not from-camcoder HDVs with mpeg2 video/mp2 audio. </p><p>you can try HDV-in-mov from this folder as ffmpeg test file, I think</p><p><a href="http://samples.mplayerhq.hu/mov/FCP/">http://samples.mplayerhq.hu/mov/FCP/</a><br></p><p><br></p><p>----</p><p>
For creating a blu-ray disc, if you have HDV MPEG-2 media that is in
blu-ray format, you can save the original quality of your work, rather
than rendering it to another format. </p><p><br></p><p>{I hope Terje will let us know if bdwrite still works with bluray pcm audio as produced by ffmpeg 5.1+}</p></div></div>
