Rendering project to Blu-ray containing both 720p and 1080p videos
on Mar 25, 2015 at 7:25:03 pm

I want to create a Blu-ray disk with a menu that will let the viewer choose to watch either video, one shot as 720p 29.97fps and the other shot as 1080p 29.97fps. What is my best rendering option?

1. Set the project properties to 1080p 29.97fps and let Vegas Pro stretch the 720p video to match settings.

2. Since I do have BorisFX Continuum 9.0 I could uprez the 720p video to 1080p first.

3. Just set the project properties to 720p 29.97fps and let Vegas match the properties for the 1080p video. This is the easiest and may not produce a video quality of noticeable difference from a 1080p version.

...or something different?

If the source is 720p then just put that on the Blu-ray and let the HD TV do the upscaling in hardware if it needs to. This will produce the best quality for everyone.

John, thanks for responding but I'm a little confused by your answer. I should mention that this is my first HD project so I'm trying to understand all the optional settings.

1. I have one timeline containing both 720p and 1080p events, which one should I set the project properties to match for best Blu-ray quality?

2. Both of these events are 29.97fps progressive. If I choose the project settings to match the 1080p event and then go to render it for Blu-ray I can choose the 1920x1080 24p template but change fps to 29.97 to match it. However, when I open DVD Architect and choose the properties settings the only 29.97 setting is interlaced. I don't want an interlaced Blu-ray disc. How can I keep it progressive? Will I have to change the fps somewhere and if so, where and how?

Thanks for your patience,
Jim

[Jim Prisby] "1. I have one timeline containing both 720p and 1080p events, which one should I set the project properties to match for best Blu-ray quality?"
I would use the one you have more of but that's just to reduce the other looking bad. If you have more 720p set the project to that. If you have more 1080p set the project to that. if you have equal amounts then it doesn't matter. Set it to either.
[Jim Prisby] "However, when I open DVD Architect and choose the properties settings the only 29.97 setting is interlaced. I don't want an interlaced Blu-ray disc. How can I keep it progressive?"
Blu-ray supports 720p or 1080i. Take your pick. You can't get 1080p. I don't know why you don't want your Blu-ray disc to be 1080i. It makes no difference since your source is progressive (i.e., both interlaced fields will contain exactly the same information). If you want to deliver 1080 Blu-ray then you need to use 1080i. You won't see any difference.

John, Thanks for clearing this up for me, now I get it. Like I mentioned, I'm new to HD editing. My thinking was that a Blu-ray disk would always require progressive rendered files like a DVD disk in SD that's why I said I didn't want an interlaced Blu-ray disk.

One more question if I may...
Regarding my timelime with both a 1080p and 720p event added, If I set the project properties to the 1080p settings is it possible or worth it to to use BCC Uprez on the 720p to raise it's resolution to 1080p for better quality?

Thanks,
Jim

[Jim Prisby] "My thinking was that a Blu-ray disk would always require progressive rendered files like a DVD disk in SD that's why I said I didn't want an interlaced Blu-ray disk. "
TV is an interlaced broadcast medium. Blu-ray wanted to be compatible so they had to support interlaced video. It doesn't matter if your source is progressive. It will just split your frame into two fields for delivery and then assemble them back together the same way. You won't be able to tell the difference.

Yes, BCC UpRez can do a great job of upscaling the 720 to 1080 without getting soft. You can try it without and see because going from 720 to 1080 might not look bad at all with the Vegas Pro upscaling. If not, BCC UpRez can give to that extra sharpness.

Thanks again, John, for your time and patience in helping me to understand these things even further.

One final question concerning a project that will be going to YouTube, Vimeo or burned to a DVD or Blu-ray disk to be shown on TV... After searching thru your previous posts about applying the Broadcast Colors effect I just wanted to confirm that after adjusting the colors appropriately with levels, color curves, etc. I should then always add the Sony Broadcast Colors effect to the master video Bus and choose the Conservative preset which will change it from Computer RGB (0,0,0) to Studio RGB (16,16,16) before rendering it, is this correct?

Thanks,
Jim

Yes, because services like Vimeo and YouTube assume that they are getting Studio RGB videos and the players will expand them to Computer RGB on playback. If you feed it Computer RGB, your videos will look darker on these services.
