Blurred Video After Rendering

Hi,

I have been putting together a video for about 4 weeks. I have been filming - editing- and placing into the final video file with the ultimate goal of a DVD.

I am using a Panasonic DV Camcorder that uses the mini-dv tapes.

I have run into a strange situation that has me puzzled and I hope someone can help me.

I have an event that I added to my video file that after rendering appears to be blury like a double image.

The whole video file plays fine in Vegas Movie Studio but when I render it to a MPEG 2 or an AVI and play it back through Windows Media Player (to preview it) or burn it to a DVD using DVDA this one event produces the blurry video and then the rest of the video both before and after is fine.

The event immediately after the blurry event was originally recorded only a few minutes after the blury scene using the same Sony mini digital tape and the same camcorder.

I have tried deleting the event and re-inserting it. I have actually deleted the event file - downloaded it again from the camcorder - re-named it - re-inserted it and I get the same result after rendering.

I have just recorded about 20 minutes of new video using the same setup as mentioned above and again after rendering it and viewing it through WMP or a stand alone DVD player I have about 50% of the video as blurry but editing it through Vegas Movie Studio or viewing it through the camcorder everything looks fine.

Please help as I am at my wits end?

Thank You!

David Beaver

Is there more motion in the "doubled" sections than in the others?

Video is made up of two fields in each frame and each field is about 1/60th second apart. When you watch the video on your TV the TV hardware shows one field, then the next, so the motion looks smooth. When you watch it on your computer screen, both fields are combined and shown at the same time. Anything that has moved between the fields will show up double because the time difference isn't being preserved.

When you view on the camcorder or in the preview window you usually only see one field and the other is ignored. This is why it looks clear there.

Try viewing the blurry doubled parts on a TV, not your computer monitor, and see if they look ok there.

The video is of flag fotball. All of the video is of the same motion. The first event has a person having eye black applied. Not a whole lot of motion.

The second video that is 50% blurry after rendering and viewing through WMP or burning to a dvd and viewing it on a tv is of a flag football game. The problem with this thinking is that I have 3 other games that I filmed that are fine.

With regard to watching it on a tv everything is perfect.

One other observation - I can view the rendered MPG 2 videos in VMS or Nero Show Time and it is fine but if you burn it to a dvd using either Nero Start Smart software or Vegas DVD Architect the video is blurred.

I also, as a test, burned just the one 20 second event to DVD by itself and the dvd was fine...but when it is part of the larger video it is blurred??
