looks like interlacing artifacts to me. the solution sorta depends on how it was captured and edited...progressive or interlaced? and what the steps were that produced the output. were any interlaced intermediate renders made?

Looks like you need to deinterlace the footage for display on a progressive monitor. What was the video format used for the final render?

All things considered, it's not too bad actually..

If you are editing in Vegas...

Do the following..

#1) Save your vegas project file as another name SAVE AS -> new name
#2) Go to Project Properties and change the format to progresive in the upper right.
#3) Change the fields to "Blend"

(I'm doing this from memory, not in front of Vegas right now - which is why not more specific instructions).

Then render your file again the same way you did before and see if that helps..

You've got the interlace blues...

Rerender the file as progressive and that will solve it.

As for the video itself, you could have reduced the length of it by editing out the 'zooms'.

So instead of waiting for the cam to zoom in, a simple cross-fade to close-up would have been much better! And then a simple cross-fade to wide. Makes the flow of the video much better!

Speaking greek to me!

Thank you all... I am going to try to rerender it. This is my first video . Danny thanks for the tips on cross fade.

Richard...I rendered it in WMV format.at 1.5 bit rate. My goal here is to have a video hosted online that my colleauges can view in China, but eventually we want to be doing DVD quality video. So any suggestions you can give me are greatly appreciated.

Bill Now speaking of interlacing, I notice when i play the video right out of my camera onto a television i get the same type of interlacing. is this because the camera does not interlace it? IS there a setting on the camera? Should i be capturing in progressive, or interlaced? Thanks again...

dave

Im still having problems trying to deinterlace the video. I dont know where to fine the project properties, im looking under preferences, perhaps im in the wrong place... I am rendering as WMV at 1.5 bit rate. Please be easy on me im new to Vegas and rendering. :-)

If there is a lot of motion in the video, you will get better results if you set the de-interlace method to "Interpolate."

I think your referring to the Field order in the properties window is that correct? So I want the None (progressive scan) option? Is this correct? Thanks again

Spoke to soon!

Okay, so i was feeling a lil cocky with my newfound knowledge, and rendered a WMV file, an H.264 file, no problem. Looks great

NOW i have been trying to render in MPEG2 format to put on a DVD and guess what....

Got that darn interlace problem again. I have tried progressive, i have tried interpolate,, dont interpolate....ARRRGH.... or is this normal for a MPEG2?

Thanks

Hi David. I suspect you are viewing the DVD on a computer? MPEG2 for DVD is interlaced, and will show these artifacts on a PC monitor. Try playing the DVD on a TV set, it should be fine.
