First, are you previewing this with an external monitor, where you are seeing the artifacts? Interlaced footage will always show up with artifacts on a computer screen.

if you have the setting of NONE vs blended fields or deinterlace fields, then Vegas will keep the interlacing as it came from the camera. With few exceptions, when you are shooting DV, you are shooting interlaced footage. Therefore, you either must blend the fields, interpolate the fields, or accept interlaced media in your project settings.

Question 2, how large is your preview window, and at what setting? Anything other than the FULL view in Preview/Good/Best could cause the image to pixelate.

Regarding people responding, give it a day or so. it's a weekend. Forum traffic is always down on weekends.

Thanks for reply Mr Spot!, (1) RE:[ are you previewing this with an external monitor?]
I have previewd the renderd Movies (with "None"setting)'both on Pc and on Tv by playing it throuhg DVD and DV tape ( after printing it to tape).
But after rendering the DV with 'blend fields option' the bad movements and lines where gone.
But through your post I understand that it is 'ok' to set it to - 'Blend fields mode'.( I was worried that the render quality/sharpness would be less through this option)

[(2)RE:how large is your preview window, and at what setting?]

Project: PAL DV Widescreen (720x576; 25,000 fps)
Preview ( does not matter actually) mostly use- 360x288x32; 25,000p.
When I turn off the 'simulate aspect ratio'option the picture is sharp again, ( but ofcourse the display then will be compressed horizontally.
Does not matter 'preview/good or best.

I still wonder if the preview window problem could be solved?

I have put the example - screenshots of the preview window problem online
For you:

( ps: does not matter if set on 'preview good or best'mode)
Thanks for any help

Looking at your screenshots I see nothing wrong.
Whne the preview window is smaller than the actual frame Vegas doesn't spend a lot of time resizing the pixels so yes you will get some aliasing. If you use (full) rather than (auto) then you force Vegas to do a full resample for preview however your frame rate may suffer.
As to your 'bouncing ball' problem, I'm concerned. I'd expect to see interlace artifacts on the preview monitor, this is normal as Vegas is displaying 2 fields together. However these should disappear during preview on a TV. Was the footage shot 16:9 anamorphic or has it been letterboxed to 16:9 and the you're using Vegas to resize it?
If the latter then you'll take a quality hit on vertical res for starters and also you may find setting 'reduce interlace flicker' in media properties will help.
If your footage was shot interlaced you shouldn't make it progressive unless you're after a 'film look' as this will cause some loss of quality. Or to look at it another way, don't try to fix a fundamental problem by introducing another complexity!

Not sure but here might be an issue - first frame you have the project set at interlaced and the next 2 frames it shows project is now set for progressive...in all cases the media seems to be progressive. My thought is that your blend mode for "auto" may not be showing you 'final' output - but you do say that it "does not matter if set on 'preview good or best".

is your footage true 16:9 or have you cropped 4:3 to 16:9? If you show it in a "letterbox" you would still somewhat have the 4:3 aspect, and if you crop it to 16:9 but keep the 4:3 (the last frame you have) it would still be 4:3 so to speak. However showing it at 16:9 would be, in effect, blowing it up and would be more prone to look a bit fuzzy - as in the second frame you show. It should also be noted that the preview settings also effect what your preview looks like on an external monitor - changing the setting from 'best' to 'full' can make a world of differance, so how does it look on an external momnitor? The same? if so try the settings at "full" and see.

Hi thanks for your replies,

[is your footage true 16:9 or have you cropped 4:3 to 16:9?]
Yes the footage is 'True 16:9' The Sony VX2000 does not crop the footages when set on 16:9, this can be seen if I hook the camera onto a television.
When previewd the footages strait from the camera on a 4:3 TV the footages are streched out ( top and below).

Maybe this sounds stupid, But untill now I have only worked with PAL DV Standard (720x576; 25,000 fps)( in vegas)
Even though shot in 16:9
This is because I overlooked the "Simulate aspect ratio option" and did not know what to do with the streched out preview window.

But I think that the "Bouncing ball problem" is solved ( thanks to you guys).
For the first time I have set the project to "PAL DV Widescreen (720x576; 25,000 fps)" and also RENDERD in that preset.

Here below I have 2 example videos.
Showing the problem and non-problem examples.

http://www.v-mp.com/Files/T1.avi
This one is renderd in PAL DV (720x576; 25,000 fps)
and also the project was set to PAL DV (720x576; 25,000 fps).
( look at the actors arm movement- shows the problem)

http://www.v-mp.com/Files/T2.avi
This one is renderd in PAL DV Widescreen (720x576; 25,000 fps)
and also the project was set to PAL DV Widescreen (720x576; 25,000 fps)
( No problem so far)

Still I dont understand it though, are the "Standard DV and Widescreen DV pixels different?

Back to 'Preview window problem:

[[Vegas doesn't spend a lot of time resizing the pixels so yes you will get some aliasing. If you use (full) rather than (auto) then you force Vegas to do
a full resample for preview however your frame rate may suffer.]]

Hier is the screenshot when preview is set on 'BEST FULL"
http://www.v-mp.com/Files/Best_full.jpg

Still the aliasing is there. ( This is especially a problem when editing videos with text or digits, they becom destorted, like the car number plates)

- Project setting : PAL DV Widescreen (720x576; 25,000 fps)
- 'Simulate aspect ration' enabled

[[[ so how does it look on an external monitor? The same? if so try the settings at "full" and see. ]]]
I dont know if I should mention this here also.
But I dont seem to get the 'external monitor working.
I have connected the VX2000 camera onto the fire wire, then set the Vegas also as it should be ( I say this because I have printed to tape from Vegas to camera before) then set the camera to "VCR"( camera shows DV IN in RED) and connected the TV on the "analoge video output" But when pressing the play button on vegas doesent seem to send any footage to the camera, and so nothing to TV. ( Normally I can wach the footage straight on TV when printing to tape)

Thanks for any help.

[[ Edit, also note, that real one player does not seem to playback the 'T1.avi' and 'T2.avi' compressed, But WM9 player does play it correct though, just a note ]]

On the DV out - this may sound stupid but do you have the "preview on external monitor" button turned on? Also I have heard that many PAL camera do not allow firewire in, only out - could this be the case with your camera as well? Not sure because you say you have done a PTT via the camera so I am not sure what the differance would be.

>>>Still I dont understand it though, are the "Standard DV and Widescreen DV pixels different?<<<

Yes they are. Aspect ratio 4:3 and 16:9 are not the same even if the frame size settings are. Really what is going on is that the information is "stored" in a 'compressed' frame - in your case 720x576. When you render a 16:9 DV file out, and you render using the correct setting, there are little flags set telling another device that it is a 16:9 file and decompress's the image accordingly. This is how DVD players work as well and how come a film that is "enhanced for widescreen" will know how to play out in a letterbox format on a 4:3 TV. (Once you tell the DVD player that you are using either a 4:3 or 16:9 monitor that is)

If you want a bit too much information on the topic look here: A Quick Guide to Digital Video Resolution and Aspect Ratio Conversions

If you want somehting Vegas specific go here: Marty Hedler's Vegas pages and click on the "Stills and Aspect" link on top.

As for the interlacing/aliasing - check the following:

Is the field order set correctly? Upper or lower? Does the imnput match the output? If this is preogressive in > progressive out make sure the settings also match. You mention that you have the preset as "PAL DV Widescreen (720x576; 25,000 fps)" however by default I don't believe it has fields set to "none", in PAL land I think they are set to "lower", so if your source footage is Progressive you may need to modify the project setting to match.

Another thing to try is to turn off the "Resample" and see if that solves it. If not than try turing on the "Supersample" with a setting of 2 and see if that helps. ANd the other things to try is, if you are taking interlaced footage in and trying to send out progressive, thry changing the blend methods.

Thanks filmy! I will try those solution!

Just one small thought here. The VX2000 doesn't shoot true progrssive scan. I'm wondering if you've switch the camera into progressive or frame mode if that is causing you some of the grief.

Bob.
