View Full Version : Help Producing Blu Ray disc with Adobe CS3

I seem to be having a nightmare producing a blu ray disc and need some help.

Does anyone use Shoot HDV on a Z1, capture and edit in adobe premiere pro, set up their chapter points and then export to encore and burn a Blu ray disc?

thats what I'm trying to do but I'm not sure I am doing everything correctly.

Capturing and editing and burning to a normal dvd I dont have any problems with but I have a client that wants a Blu Ray copy as well as a some standard def copies.

does anyone do this all within Adobe Premiere Pro and Encore?

What have the results been Like.

If anyone has acheived this I'd like to pick their brains.

My first issue is the Type? I can select Blu Ray disc single layer M-Peg2 or I can select Blu Ray Disc single layer h264.

Ive tried both settings,

for the first option I then chose a default 1440x1080 25 high quality setting.
there is another quality setting in the video tab which I left at 4
The Bit Rate encoding I left at VBR 2 pass
with a minimum bit rate set at 18
a target bit rate set at 25
and a maximum bit rate set at 30 ( all default values)

The file size came out at 11 .6 gig

now adjusting the bit rate settings increases the file size which I'm assuming increases the quality Is that right?

But is there any point or will i have problems playing the disc back on a set top player. if the bit rate is set to high? what do others use.

it took around 7 hours to encode a 1 hour project and then open up encore. After constructing the menus encore took another 45 minutes to produce a disc.

I did a similar thing with another time line and this time chose the H264 setting

this time there was no minimum bit rate but a target of 20 and an maximum of 30.

again it was a 1 hour project and I expected the encoding before opening up encore to be about the same time and was prepared to let it run over night but the process took only about 1.5 hours before opening up encore. I havent tried burning the disc yet.

So why the different times to open up encore.

I guess its got somethinhg to do with my initial project settings in adobe premiere pro.

I use a matrox RTX2 card and therefore have captured using the Matrox-HD - 1440x1080i-25fps-HDv option rather than the alternative mpeg-2-iframe option.

Any help and advice will be very gratefully received.
thanks

When encoding to MPEG2 for BluRay, leave the defaults and adjust the average bitrate as close to 35Mb/s as you can get while keeping the estimated filesize below 20Gb.

In Encore, write a BD-R image to hard disk (not a BD-RE image, unless you are using re-writables) and burn this to BluRay.

Encore wouldn't burn the image to BD-R for me, so I use te latest version of Nero, which is much better at burning all types of optical disk.

All of this takes ages to do, and I haven't tried h.264 yet because it takes even longer, but I've burnt several projects to BluRay, including one wedding, and they all look stunning on a big screen, so its well worth the effort.

David,

I don't have Adobe CS3 and have never yet burned a Blu-ray disc, but I aspire to! I do have the lastest update of Sony Vegas Pro 8.0c and DVD Architect Pro 5.0 both of which have Sony's latest Blu-ray settings in their menus. It occurred to me that you might be interested in comparing your settings with those offered in Vegas, designed to be imported into DVD Architect.

First the mpeg2 settings for "Blu-ray 1440x1080-50i, 25Mbps video stream" ".m2v":

Video rendering quality: Best
Output type: MPEG-2, Frame rate: 25.000, Aspect: 16:9, I-frames: 15, Insert I-frames at markers: selected, B-frames: 2, Profile: Main, Level: High, Field order: Upper first, Video quality: 15 (mid position of scale), Insert sequence header before every GOP: selected, Variable bit rate: selected (two-pass option available if selected), Maximum (bps): 30,000,000, Average (bps): 25,000,000, Minimum (bps): 20,000,000, Include audio stream: not selected (save as separate elementary streams selected).

Now the Sony AVC (".mp4") settings for "Blu-ray 1440x1080-50i, 15 Mbps video stream"

Video rendering quality: Best
Video format: AVC, Frame size: High definition (1440x1080), Allow source to adjust frame size: NOT selected, Profile: Main, Entropy coding: CABAC, Frame rate: 25.000 (PAL), Allow source to adjust frame rate: NOT selected, Field order: Upper field first, Pixel aspect ratio: 1.3333, Bitrate (bps): 15,000,000, Format: Video elementary stream (.avc)

Within DVD Architect, the default Blu-ray disc properties settings are as follows:
Target media size (GB): 25.00, Video format: choice MPEG-2 or AVC, Bit rate: defaults to 18.000 (mid position of sliding scale), Resolution: 1440x1080 (with the other resolutions alternatively selectable, Frame rate: 25.000 interlaced, Audio format: AC-3 Stereo (with PCM, or AC-3 5.1 surround also offered)

I don't know whether this information is of any help to you, but I guess many of us will follow your efforts with considerable interest! Thank you for sharing them with us.

Ok well it looks like I'm stepping a bit into the unknown here,

I think what I'm going to do is to try and get some cheaper (non inkjet printable Bd-r discs to experiment with and try to create a very short sequence first of all. If I get success with that then I will try the longer wedding project.

Of to another wedding now , would have been nice to have cracked this before hand though:(

David, this sounds like a nightmare - I won't go into how I make Blu-Rays as I use Edius and Encore with Procoder 3 doing the encoding, so we have totally different soft at work here, but I will say buy a re writable disc and make a small 5 minute project with menu's for testing.

I only ever have to encode once in Procoder, and whilst it takes a while, it's then only the burn time which isn't too bad - sorry no figures for any of this, but next time I make something, I'll note it all for comparison.

I'm about to fit an LG burner to one of my machines which has Power DVD bundled with it - I'll see if it works.

I currently use my Vaio to burn, with its inbuilt dual layer drive and this has WinDVD-BD player which is a bit crummy, but it works, and gives me HDMI output - looks fab.

good luck

Paul

Any suggestions where to get hold of Blu Ray re-writeable discs?

I'm asuming that these should play OK on a PC with a LG blu ray burner using Power DVD ultra software.
I accept being BD-RW the probably wont play on any stand alone players ....yet

I got mine from:

http://www.dvd-and-media.com/bluray-dvd.htm

I expect that rewrites won't play on much, if anything, but at least testing is safe, it says
on the box, 1000 re writes - not too bad.

I looked at the link on Power DVd site which my paperwork says to access for download to make it run with Blu-Ray and HDD, but they want money -
