Holy smokes. I just ran across the preference settings when you capture a video in vegas9.

It presets the MPEG video quality to 20. Cant tell you how many projects I've uploaded in the past with that unknown setting.

I'm pretty M.A.D. at Sony for not setting the default to as high as possible.

Question: whats the difference when you set this setting to 31 instead of 25?

Why would you be mad at Sony? They set it to a reasonable setting between speed of render and quality of the video. 15 is a good setting for most video.

You can make the same argument about the project preference for full-render quality. The default is Good but it also has Best. Unless you are resizing large still images, you don't need Best which is why Good is the default.

Just because every knob goes to 10 doesn't mean it's best to set them all there.

Why don't you render two videos at those two settings and see if you can see any difference. if you can't the Sony engineers were right... you only needed the lower setting.

I hear you, er, no I don't. Used to play with a guitarist that liked that number :^(

There are a lot of happy medium defaults in Vegas.

after further research I come to find out that this setting is for analog video capture. since I'm using IEEE1394 Firefire, the firewire capture "supposedly" captures the video off my miniDV tapes bit-for-bit.

as to the question of why shouldnt I be happy with the middle-ground Sony Engineers have set up....

I can understand wanting to back down some settings in order to render a project quickly so you can see the project for errors. But I dont understanding why settings arent max'ed out.

As a fictional example: How would you feel after 12mos of driving your car you could have got 32mpg instead of the 24mpg you have been getting if only you changed a setting on your dashboard? from some setting from "average fuel economy" to "high fuel economy". I trust my car's mfgr has already max'ed out my fuel economy.

To me it only makes perfect sense to have the settings max'ed with the ability to choose lower if needed.

I think it would be good practice for Sony to have ALL their hidden and obsure settings max'ed out in case someone didnt have the knowledge to know the difference. i'm a vegas user since vegas4.0 and i was two years into video editing before I even knew there was a difference between the render set at Draft vs Preview vs Good vs Best. I felt bad for all my customers who i rendered projects at the default "draft" render quality that Sony made by default. I was embarrassed I didnt know to max it out at "Best" render for best video quality. Here all along I thought I was providing teh best video..

Well, every one will have a differing opinion on this matter. I'm jsut glad to know that you CANT trust default settings that you must look at every settings to make sure to max it out right before that last and final render....if you want the "best"

[jim cornetet] "But I dont understanding why settings arent max'ed out."
Because maxing them out with no appreciable benefit makes no sense.
[jim cornetet] "How would you feel after 12mos of driving your car you could have got 32mpg instead of the 24mpg you have been getting if only you changed a setting on your dashboard? from some setting from "average fuel economy" to "high fuel economy"."
Let me give you a closer analogy: How would you feed if it took you 2 hrs to drive to work every day only to find out after a year that there was a short cut that would have saved you an hour? That's a truer analogy. i.e., why would you wait 2 hrs for your video to render when you can render it in only an hour at the exact same quality? That's the difference between maxing the parameters when you don't need to.
[jim cornetet] "I think it would be good practice for Sony to have ALL their hidden and obsure settings max'ed out in case someone didnt have the knowledge to know the difference."
I'm not sure you understand that maxing out everything does not always yield the best results. It would be like turning all of the knobs to 10 on your card stereo (Volume, Bass, Treble) before turning the radio on because clearly that must be the best sound? It's not always the case.
[jim cornetet] "I felt bad for all my customers who i rendered projects at the default "draft" render quality that Sony made by default."
I've been using Vegas since Vegas Video 3 and "draft" has NEVER been the default. The default render quality has always been "Good" which is the appropriate setting in the majority of the cases (i.e., those that are not resizing images, and only if you see jagged edges on the images).
[jim cornetet] "I was embarrassed I didnt know to max it out at "Best" render for best video quality."
As I pointed out, best does not necessarily give you the best quality. Best uses bicubic resampling when resizing images instead of bilinear. If your video has nothing to resize, Best is exactly the same as Good except that it takes approximate twice as long to render.
[jim cornetet] "I'm jsut glad to know that you CANT trust default settings that you must look at every settings to make sure to max it out right before that last and final render....if you want the "best""
Actually, most of the time your best results in Vegas will be achieved using the defaults right out-of-the-box.
