    Posted by Kyle Galbraith on November 15, 2010 at 9:33 pm

    Hi everyone,

    I am new to Creative COW, but I am hoping someone can help me with a problem I am having. I am trying to edit in Sony Vegas and even at (Preview>Full) my preview image is distorted as if it is not blended or something.

    I am also trying to capture some stills and I have the same problem even at (Best>Full). I have tried right clicking and setting the preview to scale the video to fit the preview. This clears up the distortion, but it is soft and when I save a snapshot like that the distortion comes right back. Below is a link of my problem.

    Please any help is greatly appreciated.

    What you are seeing is interlacing. Right-click the Preview window and select Preview Device Preferences… and make sure that Apply deinterlace filter is checked. If it still doesn’t look right:

    What is the format of the source video? Specifically the field order?

    What are your project settings?

    What Deinterlace Method are you using?

    When you right-click on an event and select properties, then switch to the Media tab, and tell us what field order does Vegas think the event is using?

    I would also be curious to know why you have black letterbox bars on your preview (unless you’ve cropped the video because you want them in which case the crop could have shifted the filed order)

    Thank you for the response, I will try to answer your questions.

    1. The format is DV (.avi) at 720x480x24 at 29 FPS. The field order Im not positive how to check the source outside of vegas, but if I look under stream properties in the Media tab it says Lower Field First which matches my project settings.

    2.

    3. Blend

    4. Like I said, Im not sure if I checked the source video the correct way for the field order. I just right clicked the media in my media manager and checked its properties. I did what you said as well on a clip in the timeline and it said Lower Field First as well.

    I hope this helps and thank you again for all your help. I really hope I can figure this out.

    Thanks,
    Kyle

    All of those settings look correct. I will don’t understand why your video doesn’t fill the preview window.

    Have you tried to right-click the Preview window and select Preview Device Preferences… and make sure that Apply deinterlace filter is checked?

    That should clear it up.

    I am lost as well. I have checked the apply deinterlace filter in the preview display preferences. When I right click the preview and select scale video to fit preview window it clears it up inside the editor, but when I go to save a snapshot the snapshot still looks like the image I first posted.

    I am still stuck with this problem. I checked older footage that is good because I have used it and it does the same thing in Vegas. Therefore, it is not the footage, but the program. Any other ideas?

    I have never seen this before but I also can’t explain why you have black letterbox bars on the top and bottom since your footage and the project are both PAL Widescreen. Something very strange is going on.

    The letter bars was just a crop I put on. I took the crop off and still have the same problem. I am also working in NTSC.

    Ah.. the crop can cause problems with field order but if you removed it then that should rule that out. I’m not sure why I thought you were using PAL but I see your screen shots are all NTSC.

    Ok so I was having this problem in Vegas 9. I needed to upgrade anyways so I installed Vegas 10 and the problem is still there. It is not in the footage though, I have got to be missing something dont I?

    Does this look that bad when playing? or only when you view a single frame? Have you render out some footage and watched it on a TV? Does it look OK on a TV?
