Toast 10 – Blu-ray Frustration

[Kevin O’Brien] “For that reason, I was hoping to stay with H264, which is more efficient to maximize quality at lower bit rates. “
H.264 is not recommended for BluRay yet and I’m unaware of any BluRay discs that have been released with that format. Everything I’ve purchased is MPEG-2 as it everything we’ve created. It seems that format just isn’t working well yet so nobody recommends it yet.

Hi Walter,
Thanks for the input.
The player I am writing the disc for is a Sony S500 which can read AVCHD files.
So I thought H264 would be good.
It does seem complicated to get them in a wrapper that the machine will see.
I may give up and go MPEG2. Do you know the maximum safe MPEG2 data rate for aBlu-ray BD5 playing on a Blu-ray player?
I don’t have a Blu-ray player, and my client is 200 miles away, so I can’t easily test how data rates play.Thanks,

Maximum safe? Nope.

Hi Chris,
I have had near success by exporting from compressor Mpeg2 and ac3 files at avg data rate 15mbps/max 20mbps.
Then I muxed using the free Tsmuxer to avoid any chance for Toast to screw it up. I used Tsmuxer to make a BDMV folder as it muxed.
Then dragged the BDMV folder into Toast which immediately burned it to a disk image (for the test).
Mounting this image and playing it with Toast player it looked pretty good. Some smearing of motion.
I’ll try higher data rates and see if that helps. Since i’m 720p/60, the high frame rate needs as high a data rate as I can play. You probably are using 30 or even 24 frame sources, which don’t need as high data rate.
The trick is finding the highest data rate that does not stutter in playback.
Compressor’s MP2 might be a source of the slight stuttering on high motion parts.
Would love to try Streamclip to make MP2 file, but still can’t figure out why all convert options are grey no matter what I feed as a source.
The trick is finding the highest data rate that does not stutter in playback.
I’ll update if I find out more.Thanks,

Yep, much higher. Your data rates are pretty low. We only use Toast to burn the ISO files to BluRay, never to author or create the discs.

I’m working with 1080 60i files and encoding at 20 mbps avg. and 25 max.
It’s an HDV file, so I guess there is no point in going higher than 25 mbps.
I’m not familiar with TSMuxer. Can you do any kind of authoring with this program? -
Hi Chris,
TSmuxer is a bit of a mystery. All the documentation is in russian, but it is free and does a good fast job of muxing without messing, which I don’t trust Toast to do. It will also create a BDMV folder with all the stuff required so that for people like me who don’t want a menu, it’s ready to burn in Toast.
Can’t author with menus or any extras.
I just don’t think on a BD5 I can get a data rate high enough to succeed with 720p/60frame material.
I’m still experimenting.
You can find TSmuxeR at https://www.videohelp.com/tools/tsMuxeR.
Like I say, I’d love to use MPEG Streamclip, but the convert to menus in it are all greyed out.
I see all kinds of posts from people claiming to have succeeded in making H264 AVCHD disks, but I think my 60fps content may preclude this.Thanks,
Kevin
