SJ4000 files to Blu-Ray

[Kravex]

What’s the best way to burn the video a SJ4000 takes onto a Blu-ray as a Blu-ray movie? Got a Blu-ray burner just need to know what software converts the files it produces correctly without any loss of quality, thanks.

Post the details from one of the mp4/mov files. Use mediainfoxp, open the video and then copy all details. So we can check if it's blu-ray compliant(no video reconversion).

Or just try a good authoring package like tmpgenc authoring works.

Thanks for a quick reply!

30fps is not a valid BR frame rate.

You could slow it down in Avisynth with a simple script such as:

QTInput("yourmovie.mov")
AssumeFPS(30000/1001)

(You will need to google for the QTInput plug-in as it isn't standard)

Then load your original file into Audacity to change the audio speed to match.
Then load the Avisynth script and the Audacity output into an authoring app like TMPGenc Authoring works.


(Or just load it into TMPGenc Authoring Works as Baldrick suggested and live with the frame blending. There is no lossless way to get this file onto a BR.)

As per MediaInfo, the audio sampling rate ain't compliant either.

Progressive 29.97fps or progressive 25fps isn't strictly according to spec for 1920x1980 BR. I know what the videohelp listing says in https://www.videohelp.com/hd#tech, but strict per-spec BluRay at those frame rates is supposed to be interlaced. Some players might handle it correctly, others might play as interlaced anyway. Motion and pans with 29.97p might look OK with some setups, not so OK with others.

What about GOP's? Doesn't "M=1, N=15" mean there are P frames only, no B frames? But sometimes those "M, N" numbers look different in many specs.

The strict encoding specs are here: http://forum.doom9.org/showthread.php?t=154533

I know what the videohelp listing says in https://www.videohelp.com/hd#tech, but strict per-spec BluRay at those frame rates is supposed to be interlaced.

I have changed the 1920x1080 29.97/25fps to interlaced. And added the doom9 link under more information.

Probably a good idea, Baldrick, nice work. I've communicated with a number of people about the doom9 version, and they say that when they stick to the strict specs they have no problems with BR disc. BR for PC play, now, that might be a different story. There are PC media players that can handle just about anything, I guess.

I note that TMPGEnc was mentioned in an earlier post in this thread and elsewhere. I've used their stuff for years, and they always struck me as being fussy about proper MPEG/BD/AVCHD structure for standard discs. They'll let you make oddball video for PC playback or the web, but they get kinda rude if you try to stretch non-compliant media too far.
