Used 30p for 1st time - pixelated

Hey. Im using a dvx100b with vegas 6. For the last two years Ive only shot in 24p and have had no issues sampling video into vegas 6 and so forth.

But yesterday, I shot in 30p (29.97) for the first time. It looks great on the dvx or if I play it back on the tv. But, I sampled it into vegas 6 and it looks bad. The pixels are oversized and it looks like stretched out horrible video (its very pixelated). It must either be how it was sampled or some setting in vegas that im not seeing...

Any help is appreciated...
 
I checked it in the capture mode and its 100% fine looking. It looks bad in the preview window AND if I render it (if I render it, it looks bad like in the preview window).

In the properties of the clip it says 720x480x24, but under the preview window it says 720x480x32 (for Project, Preview and Display). Not sure if that has anything to do with it...
 
Could be a bad capture or footage interpretation, although Vegas is pretty savvy on interpreting the correct codec and frame rate most of the time. Confirm that the clip properties reflect the proper footage properties and frame rate. Also make sure the project properties match the desired playback/output. I am not in front of my editing system but it sounds like Vegas has two different color bit interpretations, varying between footage and display.

If no one else offers a solution I will check this later when I am back at the studio to see if I can offer another thought.

Follow up to my earlier post. The preview window stats of 720x480x32 confirm the available resolution of the preview window and the the 32 indicates that your preview monitor is set to True color or 32 bits of display capability. I use Vegas 8 that offers a 32 bit floating point option for footage that is more than the 8 bit color space previously unavailable in prior ver. of Vegas and not related to you. I apologize as I was confusing the issue. I didn't even have a drink yet when I posted earlier.:)

Is your preview monitor a CRT or LCD? If its an LCD 30p would be great but if the resolution of the LCD most likely exceeds 720x480 it would stretch the video and it would pixelate.

Lets hear more.

Yes, I have a high res LDC monitor... but, I have been using vegas 6 and have done other videos for well over a year - and they all have looked fantastic (they were also all 24p). Its really strange. If I open the capture mode under "file", the 7 pieces of footage are still there and if I click on one its starts playing the "capture preview window" - and its perfect. I just cant figure why it looks pixelated in the normal preview window in the main editing area. 30p is progressive scan, right? Cuz im using the dv ntsc template for the file properties and it has lower field first for the scan (but even when I change it to progressive, its still blocky - unless i need to restart vegas)
 
If you have 30p footage which is Ideal for web or computer display your project should display nicely on a progressive scan monitor. The frame rate really shouldn't affect the pixelization issue which is either due to a mismatch in resolution or color space issues. Is the whole image strongly pixelated or say areas heavy with red. DV will pixelate over saturated red areas. This is often reduced or resolved by applying a Chroma Blur filter. However, if the pixelization is throughout then something else is the culprit. You are using the 720x480 DV template not 720x480 widescreen or Pal template?

YES YES!! That must be it! Its a music video and there were heavy amounts of red lighting shining on the subjects... I just used the color corrector to turn do the saturation and its looking close to normal quality now.... I guess everything is ok, just the lighting was the issue... But i should change the field to progressive still in the ntsc dv template for the project, right??
 
If you are going to display on the web then set to progressive if your going to dvd use the 29.97 for max compatibility.
