render question
Here i go again asking the same render questions but this is driving me crazy. I have obtained a bitrate calc and I have been following the steps however when I render to MPEG-2, my quality from the output looks like something out of reruns of M.A.S.H. It is horrible. I mean when I look at the footage from the timeline on my external Sony monitor, the footage is crystal clear. Once I render to MPEG-2 (and i have tried evey template possible), it looks like footage from a single chip low grade camcorder. How can I get my footage to look crystal clear on output????
Sorry for the redundant question but I cannot output this look to clients. Please help….
P.S. Here are the settings I used recently, maybe I did something wrong:
NTSC DVD stream template (Will it look better if I choose a DVDA template?)
79 minute video
Max rate: 9,408,000
Average rate: 7,344,000
Min rate: 2,000,000Looks horrible (To me anyway)…Noisy, grainy, ect..
Is this right??

First of all, I’m assuming this was a firewire capture and not analog.
What kind of camera was used? I’m asking because I’ve done encodes of 2 hr. projects that looked very good on DVD – but they were shot with a 1/2″ 3-chip camera.
The settings I get using my bitrate calc (zipped version here) are as follows:
Max: 8000
Avg: 7200
Min: 3600
The higher Min value may help.
Also, you are using AC3 audio, right?Mike

are you burning to a dual layer DVD disc??
you must be because you cannot fit 79min onto a single layer disc with the bit rate you are using .. IMO if it is fitting on a single layer then DVDA or whatever DVD software you are using is re-rendering the mpeg2 to fit it on a single layer = noisy, soft image, faded colors …

various camera were used including PD170, canon xl2 ect. Great camera’s and like I said, it looks great in the timeline on the external but it look crap when compressing to MPEG2. When I render to AVI, it looks good but when I author in DVDA, it needs to render back to MPEG so it doubles my render time.
AC3/PCM audio is being used.

Let me see if I am doing this right. Say my video is 84 minutes. My calc says the following for an 84 min video:
Min: 3536
Average: 7080
Max: 7784Within the VBR MPEG properties in Vegas, should it look like this:
3,536,000
7,080,000
7,784,000??????Is this correct??? Man, this is more confusing than I thought….

would drop your rates a bit, esp those rates in your first post – waaaay up there. unnecessary.
also, have you factored in how much space your menu system in DVDA is taking up?

Woaaaa
Your 9,408,000 high setting is way to big. Don’t go over 8,000,000.One thing to try is render your video to AVI then bring it into DVDA. When you optimize, check the box “fit-to-disk” and just let DVDA figure it out.
I do that everytime I got a video 90min or more. I got 120 minutes on a DVD-5 at pretty good quality letting DVDA figure out the bitrates.

do a 3 min render test ..
use you setting , use the standard mpeg2 DVDA ntsc video stream template , and a 3rd one at a constant 6,000,000 bit rate..
after the 3 mpegs are rendered drop them in Vegas TL to see which is cleaner ..
