Authoring blu ray from .ts file

[twinaleblood]

Hello there.
I'm very advanced when it comes to edit and author dvds (I'm familiar with many programs: Dvd-lab PRO 2, MPEG Video Wizard, AVStoDvd, Sony Vegas, etc etc), but I'm a complete newbie when it comes to blu ray.

I've bought a LG bd recorder and I would like to start my first project. I have the a .ts file (17 gb) of a concert and I would want to make a blu ray out of it. Where do I start from? Any suggestions would be much appreciated. I tried to browse through the guides here on Videohelp, but I'm a bit confused and still not sure what's the best thing to do.

Thank you so much in advance for taking the time to help!

What do you want to do with the .ts file? Do you need to edit it in any way? Or apply filters? Is the .ts file as it exists now already compliant to Blu-ray specifications? Do you want a menu?

If none of these are problems, then it is very simple to get the .ts file into Blu-ray format without a menu. Just use tsMuxeR.

Best to use MediaInfo and post the results here in your thread. You'll give the members here a better idea of what you have to start with. I find the text or tree views in MediaInfo to be the most informative.

I think it's already compliant (I'm pasting the specs at the bottom of this post).
I don't need to edit it in any way. I would only want to add chapters and try to make a menu.

Making menus for Blu-ray is one of the biggest issues for free programs. You might try multiAVCHD, but you'll need patience. It is cranky, slow and buggy in my experience.

MP2 audio might be another problem. I'd probably convert to AC3.

MP2 audio might be another problem. I'd probably convert to AC3.

Since the audio stream has only 2 channels, I would choose uncompressed PCM.
Acceptable filesize, and no loss of quality.

At the risk of offending and contradicting everyone here at videohelp, I'd offer that published specs say a GOP of 15 is not strictly BluRay compatible. Many authoring programs will re-encode the video for BluRay. It might work for AVCHD but I never tried it. Then again, MediaInfo doesn't always report GOP size or other factors accurately.

I don't understand...the link you posted says that AVC 1080i with a 25.000 framerate can have a maximum of 25 frames per GOP. Thus with GOPs of 15 frames, it should be compliant.

[LMotlow]

So, go ahead and try it.

I have TMPGEnc Authoring Works 5, and it works. Then again, I didn't understand your explanation. You say it won't work, but posted a link to a site that says it's compliant. What I am missing here ?

I don't know if a GOP of 15 is valid, but the GOP length is most definitely allowed to be less than the frame rate. I examined at a commercial Blu-Ray disc from Warner Brothers with DVDFab Passkey running in the background. The video is 1080p23.976 AVC High@L4.1. The GOP length is 20. (I counted the number of frames per GOP manually in an editor.)

The specs at LMotlow's link said 24 frames per GOP for 1080p23.976 AVC High@L4.1. I'm guessing that is the maximum number of frames allowed per GOP for video with those specs, not the minimum. The chart says it is the maximum.

[Kerry56]

After a bit of reading, it seems that bitrate affects GOP length in Blu-ray video. With less than 15mbps bitrate, a two second GOP is allowed, anything more requires max 1 second GOP, which with this example would be 25. But shorter GOP's are allowed, especially with open GOP's. (don't know which he has)

Try it in TMPGEnc Authoring Works. You'll learn more by experimenting than waiting for us to confuse you.

If burning to discs, this would be a good time for a BD-RE, to test in a few players.

That's what I said. Try it . If TAW5 took it, anything will.
