Rendering 30P for Blu Ray

Hi everyone,

I have a project that includes 30p footage from a 5D mark 2, and 60i/30fps footage from an XH-A1s. I did a render for blu ray using pro 10 and once in DVD Architect, I was given the message that DVDA would recompress the footage. Of course, I don't want that to happen because Vegas has already created a MPEG2, Blu Ray 1920X1080 file for DVDA and took hours and hours to do it.

It seems that for DVDA to accept an MPEG 2 from Vegas, I have to use one of the Vegas templates without making any changes to the template. I did some tests of different 1920X1080 renders to see if DVDA would want to recompress them. It accepted a render from one of Vegas 10's templates. Which is fine. But my only concern is that when creating files for DVDs I select "none (progressive scan)" under "Field Order".

For Blu Ray I can't select this for my progressive footage. I'm concerned because as I watch in the preview window I see lines in the footage that looks like interlacing. Since I have to let the computer work for hours, I need to know if I'm rendering correctly so I don't waste a lot of time. And I don't want the rendered file to end up with this horizontal lines.

Any insight would be greatly appreciated.

Re: Rendering 30P for Blu Ray

Mike,

Unfortunately, Blu-ray only supprts 1080p at 24 fps (and no other frame rate). 1080/30p must be encoded as 60i interlaced (which in this case, will merely convert 30p into 60i PSF). Blu-ray does support 1080/60i natively, however.

Progressive greyed out in DVDA properties, says "NO"

24p vs. 30p Blu-ray

Easy way to create Blu-ray/AVCHD using the X264 encoder

The last thread by Phil Lee seems to offer hope that you can do what you want.

Re: Rendering 30P for Blu Ray

Hi guys,

Thanks so much for the replies. I went ahead with what I think is the right process (unless I completely misunderstood everything I just read) and am burning the first BR right now. I should know in a few minutes how it turned out.

Re: Rendering 30P for Blu Ray

Hi

If you haven't already I'd recommend a BD-RE disc so you can reuse it should a test not work well.

I have posted an application on here that uses the rather good x264 encoder, it also takes 30p and converts it to 60i PsF for Blu-ray, might be of use. Easy way to create Blu-ray/AVCHD using the X264 encoder Sorry just seen the link as been posted above already.

DVD Architect can be a bit funny sometimes and starts wanting to re-encode this and that unless everything is just perfect, you might want to try ::: multiAVCHD home ::: as an alternative, it seems to go with the flow.

Regards

Phil

Re: Rendering 30P for Blu Ray

Thanks Phil. It actually came out fine but I'll look into these suggestions when I have a few moments. DVDA is usually fine for me, but you're right in that it can be a little irrratible.
