My footage video is an avi 720x256, 16:9 (widescreen, I guess)
Once rendered in FX (uncompressed)the clip does not keep that format, and instead I have black at the sides.
I have checked that the footage video is that format.
In the project settings, I choose D1/DV PAL Widescreen (1.42), Interlaced (even)and sampling 4:2:0 (Mini DV Pal / HDV)
What am I doing wrong?
Thanks for your help.

PAL footage should be 720x576, if I'm not mistaken. If your is 256, then it is extremely widescreen, and must have been cropped down to that size, rather than using anamorphic pixels. I'm guessing that was just a typo on your part, but if not let us know, as the issue will need to be handled completely differently.
It sounds like you have everything set up correctly, so it may just be that whatever program you are using to view the rendered footage isn't recognizing it as widescreen, so you just need to tweak a setting in that program so it displays properly. I'm guessing this is being viewed in your video editing program? If not, then the black bars would indicate a different problem, as the footage would have to be the wrong shape within VisionLab.
So, if it is your video editor that you are using, you should be able to very quickly adjust the pixel aspect ratio for the footage within that application, so it displays properly.

You are right, my footage is PAL 720x576, it was a mistake.
My editing program is Pinaccle Studio 14. It recognices widescreen.
I think the problem is FX renders as 4:3, and I need 16:9. Please, is there any way to set output rendered files in 16:9 aspect?

VisionLab renders the footage correctly, its likely just a matter of Pinnacle displaying it using the wrong pixel shapes. In Pinnacle, set the pixel aspect ratio for the footage to widescreen, and it should be fine.

Thanks again, Axeman. Please be patient with me, Im a filming and editing lover, but not an expert.
Now I have solved the problem. I didn't understand it until I realised that one thing is widescreen 720x576, and another thing is pixel aspect ratio, in mi case 16:9. Am I right? As I didn't see an option to fix aspect ratio in FXhome, I was confused.
Yes, you are right. Fx renders widescreen correctly. Pinnacle flag it as 4:3, but finally I have found the option to change it to 16:9, just right clicking the clip and selecting this option. My fault. Hope it helps any other Pinacle user some day.

Not a problem, pixel aspect ratios is an area that can get a bit confusing, especially when you are fairly new to working with video. but it sounds like you are understanding it correctly.
Video frequently uses pixels that aren't square, and most widescreen video stretches each pixel a bit horizontally, to increase the width of the total frame. So if your software (Pinnacle in this case), displays the pixels in the incorrect aspect ratio, then the whole video will appear squished. to further complicate things, the standard and widescreen pixel aspect ratios are different from one video standard to another, so its relatively easy to get confused.
Glad you got it figured out though, and if you run into any other problems or have a question you can't find an answer to, feel free to ask.
