[Nigel O'Neill]“Is there any reason why I should not use DV WS project properties to edit an HDV or AVCHD project and then change it to HDV 1080i when it comes time to render?”
Yea, DV Widescreen is not 16:9 and HD is so your aspect will be slightly off when you switch. Also if you add any titles or other generated media, those titles and media will be SD quality and when you render HD you will be resizing them. You always want to work in HD and render to SD.
[Nigel O'Neill]“The reason I do this is I typically use 4 tracks to edit a multicam project of HDV and AVCHD media using Ultimate S, and I find that this method allows a reasonably workable and smooth preview rate. “
Create Proxies with Ultimate S Pro and edit using the proxies. Then have Ultimate S Pro swap them out before final rendering. All of this can be accomplished from the Render tab in US Pro.
[Nigel O'Neill]“The output is for both DVD and bluray (rendered out using their respective templates). The quality seems fine, but I was wondering if there was a strong technical reason against doing this.”
If you’re happy with the quality it’s hard to argue with that. As I said, the aspect will be slightly off and generated media will be created to match the SD project.
[John Rofrano]“As I said, the aspect will be slightly off and generated media will be created to match the SD project.”
I do switch back to 1080i project properties and then do the render to DVD/bluray and have noticed things on the timeline do appear to slightly switch, but if I understand you correctly, if I imported media into an SD project that I later switched back to 1080i, it assumes the properties of the template it was imported to.
[John Rofrano]“Create Proxies with Ultimate S Pro”
I saw that and tried it a few weeks ago. When I applied proxies for a 1 hour multicam project (on the timeline), it was still going after I left it overnight. I assumed Vegas had crashed. How long should proxy creation take?
You should be creating DV Widescreen proxies. These should not take that long to render. If you are using some other format then it may take longer to render. Vegas Pro 12.0 has built-in proxies so if you are using Vegas Pro 12.0 you should try the built-in proxy support.
[John Rofrano]“You should be creating DV Widescreen proxies. “
Ah, therein lies my problem. I was selecting the Render Video Preview check box in the Quadcam tab and clicking on apply, not the Render tab, plus I noticed the template defaults to NTSC, and in my case, has to be set to PAL DV WS proxies.
[Nigel O'Neill]“I was selecting the Render Video Preview check box in the Quadcam tab”
Yea, that feature will render the combined Quad view as a single video. I didn’t take that long to render in the days of DV and HDV but with today’s AVCHD codecs, I can imagine it takes a long time to render. You will much better off using individual proxies or Vegas Pro 12.0’s proxy support.
