Hi to all..
First of all please excuse my poor english.

I always use SCENALYZER LIVE to capture my video from my camcorder (sony pc101e pal) to dv avi. Then i use Vegas 4 to edit and the render again to dv avi pal so that i can encode my video with procoder to mpeg2 and burn it on dvd-r.

But......

I recently bought a sony 32FQ80 widescreen tv and i want to convert some of my videos to 16:9 so i will not have black bars next to my picture. I do not care if i loose picture if i crop up and down.....
How can i edit a 4:3 dv avi clip in vegas and then render it to 16:9 dv avi without messing up the aspect ratio (wide heads and weird picture)???

Thank you all in advance

You can use the pan/crop tool on Vegas, and put the 16:9 setting, you only crop the image, the result is that you don't have the black bars. You loose a little on the image but is not a big matter. But you can also use the zoom tool on the TV set and if it's a Sony I think it has a setting called Natural Zoom or something like this that makes a stretching only in the edges of the picture without stretching the center.

You can shot the video with the 16:9 setting on the camera, but in some cameras, I don't know if it is in the pc101e, the effect is the same if you crop the picture in Vegas. Some cameras have a "false" 16:9 that is only a crop/stretch, but is quite good. I have a DSR200P that makes this, but the result is very good for me.

Hope this helps you.

My english is bad also ;-)

Hi

I was given an excellent guide from here on how to do this.
I do not remember the name of the guy who produced this.
My apologies and thanks goes out to him.

The Guide:

Start with the PAL Standard project properties and place your avi file(s) on
the timeline. Now, with the 'Event Pan/Crop', select the 16:9 Widescreen TV
aspect ratio. This gives you black borders in the preview window, cutting
off the top and bottom part of the original 4:3 image.
Now you should change the 'project properties'. Lower the height until the
black borders are hidden, without stretching or changing the aspect ratio of
the image between the borders. This gives you something like 720x432,
although it may depend on the pixel aspect ratio, so change the height until
the black borders are no longer visible in the preview window, without
further clipping the 16:9 image.
Now select 'project properties' again and choose the 'PAL DV Widescreen'
template. This should give you back the 720x576 resolution, but now you'll
see a stretched (anamorphic) image in the preview window.
Render the project as DVD PAL, but use the custom setings to select the 16:9
aspect ratio.

One more thing, which I have already explained in another thread. If your
source material is 720x576 and you select the '16:9 Widescreen TV aspect
ratio' template in the Event Pan/Crop settings, VV3 makes the resolution
720x405. That's only correct if you're working with square-pixel source
material, which you aren't if your avi file is 720x576. The correct
resolution, after removing the black borders, should be 720x432. I'm pretty
sure about this, since over here we have PALplus (PAL 16:9) broadcasts. If I
capture a PALplus program and remove the black borders, I end up with a
720x432 resolution. If VV3 changes the resolution to 720x405, I lose more
than just the black borders, which is obviously not what I want.

That's why I've made a custom 720x432 template in the Event Pan/Crop
settings, to get the correct PAL 16:9 aspect ratio.

Regards

Try this:

Start new project (File > New), select PAL Widescreen template.
Bring in 4:3 footage.
Open Pan/Crop.
Right-click, select "Match Output Aspect"
Done. Render to PAL Widescreen (AVI / DV or MPEG-2).
