Hi
I'm running VSP x5 and have made a 90min film with my AVCHD 1920x1080 files. I'll be making some SD discs and HD discs. There wasn't a lot of enhancements to the footage except for several clips that needed a few filters put in. The Project Settings are MPEG Standard Definition dimensions.
When I edit my project, I always observe the Smart Proxy Queue manager, wait until everything coverts, and I get very good smooth action in editing. (probably a solution to many of the problems that needlessly occur elsewhere in the forum).
However rendering takes AGES and AGES (reached 40% after 4hrs). The box is checked "Perform Smart Render". Why is it when I've already waiting for files to be downsized when I first added the clipsto the timeline....can I not take advantage of these and save time?
What else can I do to speed up render time?
Please give a few suggestions
Phil

Re: Slow Render Times
First, SmartRender only works if there are parts of your project which are the same as those of the final product you are making, and it only applies to those clips with those same properties. Since you are (presumably) starting off with AVCHD and down-converting to standard def DVD-compliant mpeg-2, SmartRender has nothing it can work on so doesn't come into action.
Second, I think you will find that the proxy files created by SmartProxy are not DVD-compliant mpeg-2, but use some other codec to produce fairly low quality but speedy copies of the original and slow or erratic high def AVCHD. So you wouldn't want them anyway.
And I am afraid that AVCHD is the most demanding of all consumer formats currently on the market. You need a pretty fast computer to handle them well, and even then they tend to be rather slow in rendering. You haven't given any specifications of your own computer on which to base a judgement (e.g. CPU), so I can't really say, but a notional 10 hours to render a 90 minute project sounds rather heavy, but is probably still within the ball park if your computer is not particularly powerful.

Re: Slow Render Times
In addition to what Ken stated ...
A standard DVD can only hold 60 minutes of video at best quality (720x480, ~ 8000 birate). Since you are trying to put 90 minutes on the DVD, the video has to be compressed (lower bitrate) to fit on the DVD. This will of course also give you lower quality. All of that will also increase the rendering time.
