Yes, I think so. The output above was from my openSUSE system's ffmpeg
after adding multimedia codecs and enabled applications following the
unofficial guide:

Yes, FHD, HDV and SD DV are identified here by their standard pixel
resolution, frame rate and interlaced or progressive video.

Compare also with Settings>Format window's Presets up to the left (where
HDV and DV are listed for the Import video)

I think I have tested both methods, mostly in 2016/201, and just a few
later. (Beside I have digitized several analog S-video to DV video
files and recorded them to BD-R data discs as backup. I have at least
20-30 of each Hi8 and HDV tapes left).
I could not find manual documentation for the presets. So possibly
Andrew with better knowledge may step in here and explain better?
I will just add that It possible to render various .m2ts files, test
mediainfo and playback using a media player like VLC.
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
While DVD use MPEG-2, I cannot see MPEG-2 with high bitrate for SD DV
(or HDV) on Blu-ray is possible?
