UnSat Video Rendering, Pls Help

Chirdren wanting to slam SF need not respond to this.
After a 100 hours or so of testing, I simply can not get VV
2.0a to render video to my satisfaction and it is not
broadcast quality. Actually, it looks like 20th generation
analog stuff. I have tried every conceivable "render as"
setting combination and codec there is, but the quality is
not there. I import high quality video and it comes out
unacceptable. Particularly in the area of pixilation in
all scenes, and a high amount of strobing in contrasty
scenes. This is with no effects/modifications of any
kind. I put the exact same footage in Premiere on the same
PC and it renders true broadcast quality with high
definition, sharp lines, and no pixels or strobing
regardless of how challenging the scene.
I bought VV because of it's outstanding GUI, but I am now
forced to stick with Premiere. This IS NOT a hardware
issue! I thought it might be that VV didn't like the DV500
avi's I was using, so I even went out and tried an OHCI
card, but that didn't help any. I noticed it does small res
OK, but not 720 X 480 NTSC DV.
a) Does the VV 2.0a rendering engine have some undocumented
weaknesses, and b) If so, will it be true broadcast quality
in future releases? If so, I'll leave it installed and
look forward to future patches or upgrades.
The current quality is Ok for a beginner making e greetings
but that is not what I'm doing.

Hi Kris -
I just finished a project on VV2.0a which used DV captured through
the Capture/Print-to-Tape tool from my miniDV camera. The captured
file was 720x480 with 16bit 48khz audio. The codec used was DVSoft
(which must have been installed with my camera's software). I did my
edits, audio sweetening and some effects and then re-rendered to the
NTSC DV template. It was explained to me that any sections of video
that are untouched (i.e. no effects, not crossfades) remain that way -
they do not get recompressed. Pre-rendering sections also saves time
in the rendering process. I don't know why you're experiencing
quality probs with the render - mine came out just as I expected it
to. Now, granted I'm not a pro video person (I own an audio-post
studio) but I could not see any degeneration of the video compared to
the original.

Are you sure your project settings match the original capture and
that your render settings are not recompressing? Also, you might want
to direct this question to Dave Hill. You'll see his posts here on
the forum.

Good luck.

Charles.

Thanks Charles and I'm glad someone is having a better go at it than
me. I've tried your suggestions and hundreds of other things to no
avail and I'm just ready to beat my head in the wall at this point.
Maybe I just have a cursed copy? I'm not a video pro either but I
know degenerated video when I see it. I will see if SF has any ideas
via this forum and if not will formally contact their support staff.
I havn't given up yet, and the VV 2.0 GUI is best thing I have ever
seen (that is coming from a software developer...).
Although probably not related, out of curiosity what brand camera and
capture card are you using?

I'm using a Canon Elura and a Texas Instrument OHCI compliant
firewire card.
Can you do the following: go to the Project Properties page (alt-
enter) and write in your settings. Also, what render options are you
using? What are the video tab settings? Does it seem like VV is
resizing the video? How are you playing it once rendered?

I too think VV is the best GUI for any video editor I've seen.
Good luck.

Just FYI -
here are the sttings for my last project:

Original .avi specs - 720x480x24, 29.970fps, format:DVSoft (from the
Media Pool description) Field order - Lower Field First, pxel aspect
ration .909, alpha channel - none.

Video Project Properties:
same as above plus "good" resolution rendering quality

Render settings - NTSC DV default settings.
