Blu ray options?

Hey guys,

It's been 5hrs of HDV MP4 rendering straite from the vegas timeline to Blu ray. It's only at 8%. I don't even want to imagine what an HDV MPEG2 will render at. My project is 2hrs long with some small graphics but why does it take soooooooooo long to render? I can't use DVD Architect 4.5 because it does not support Blu ray authoring so is this is the only way to burn to Blu ray?.

Thanks.

MP4 renders significantly slower than MPEG2. Also, wait until June 16th when the DVD Architect v5 is released. It will support Blu-ray authoring and will be a free update.

Debuman, you may get more helpful feedback if you posted your system specs in your member profile.

You got it.
Thanks for all your help.

John Cline,

So if MPEG 2 HDV 1440-1080i is faster then MP4 H.264 HDV 1440-1080i for rendering, what about the quality. Which one has the best video quality when rendering.

Does it matter how long the entire project is because I'm thinking the longer the project on the timeline the more it has to compress which means the video quality will degrade. Is this true?.

Thanks.

Yes, it's true. It's all about the bitrate, the higher the bitrate, the higher the quality and the larger the file. h.264 is a little more efficient, so it will look as good at a slightly lower bitrate than MPEG2. However, there is nothing inherently wrong with MPEG2, it can look very, very good. The quality difference between h.264 and MPEG2 diminishes at higher bitrates.

How long is your program?

Also, if you are editing HDV, that is, if your source footage is MPEG-2, Vegas can smart-render portions of it, which means that your footage will typically be higher quality in MPEG-2 than in AVC. That is, of course, assuming you are not doing any serious amount of color correction etc, and that the footage actually can be smart rendered.
