Some help creating a BD-Rom

The last time I created a Blu-Ray from footage shot with my EX1 I did it on a Regular DL DVD.

1. Edited the 1920 x 1080 60i footage on the Vegas timeline using mxf files.

2. Rendered Tools/Burn Disc/Burn Blu-Ray disc

3. Chose the Blu-Ray 1920 x 1080 - 60p, 15 mbps VBR template (MC Mpeg 2) Video Stream

4. Dolby Digital AC3 Pro audio

5. Rendered iso image only

6. Burned the iso to a DL standard DVD with ImgBurn

7. No menu.

Turned out very well. It was around a 40 minute video

Now I have a video shot the same way and edited the same way that is 1 hour and 2 minutes in length. This time I want to burn it onto a BD-R and use a simple menu.

Since I haven't done this yet, rather than throw away a bunch of them experimenting I was wondering which settings and method you would recommend.

NOTE: I also have ProCoder 3.

Thanks,

John

Why not use DVD Architect? It is relatively straight forward to create a BD with menus using it. If you render out compliant video and audio it should not recompress although I have found otherwise for audio.

Use the AVCHD template for DVD media or BD template for BD media. (If you make an AVCHD disc, you may then need to use AVCHD-Patcher to make it play on most BD players.)

Thanks Peter, but isn't that designed for 1440 rather than 1920?

I have only made AVCHD discs, not BD discs. When I used the AVCHD template for 1920x1080, DVDA did not recompress, but it did if I used the BD template.

Edit

If you use Vegas 9c (but not later) Vegas will not re-render video clips that match the project template and have not been touched.

I use DVD Architect all the time to author Blu-ray discs. I typically render using a high-bitrate MPEG2 Blu-Ray template.

One of the Vegas templates? I attempted to use the Sony AVC Blu-ray template with some light sharpening as the only effect on the timeline and the estimated render time was 35 hours for a one hour video. I cancelled that.

Yeah, AVC is PAINFULLY slow and could really benefit from CUDA GPU acceleration. That's why I said that I use the MPEG2 Blu-ray templates, it's much faster and at high bitrates looks just as good as AVC.

There must be something wrong with your workflow somewhere. AVC render is slow... but not that slow. I can render a 3 hour time line in the time you list (with a Q6600 quad)

For the record... I do not have problems with DVDa re-compression with the standard AVC (1920x1080) template and the AC3 PRO encoder. I can also use the AVCHD template which outputs a M2TS.... but you must do this WITHOUT audio (go to custom and uncheck audio).... then render out a separate ac3 pro file. (The avchd template uses the STUDIO ac3 encoder which is not accepted for Blu Ray)

Thanks John,

I think I will do this over. I rendered using a Procoder 3 template at 24,000 kbps and DVDA is forcing a recompression.

Mine is a Q6700 quad. I don't know what could be wrong with my workflow. There isn't much to it. I edited using 1920 x 1080 .mxf files on the timeline. Added light sharpening to the whole project and chose the AVC template. What's wrong wih that workflow? Maybe it's the sharpening that's slowing it down that much. There isn't even any color correction.

If you are commenting on my post, my issue was not actually with Vegas but DVDA. When authoring to a BD (actually an AVCHD disc) using an .m2ts file straight from my camera without change, DVDA insists on recompressing the audio although the manual says it is compliant (AC3, 5.1 surround, 448 kbps and 48 kHz.).
