@xOv3Rz @Dexcon Hi, how about just dragging a Bezier mask on to the preview window so it loads to the Video Output FX ?

@Former user  ... yes, that works really well. But it would be great if the Vegas team could add presets for the various well-known widescreen aspect ratios via the Bezier Mask FX or the Crop FX so that 3rd party FX/.png templates wouldn't be necessary - or guesswork/calculations at setting the required aspect ratio manually in either of those Vegas native FX.

@Dexcon Yeah, I've just been going through cinema/wide screen aspect ratios options online, there's loads but these sizes can't be put into bezier 0 - 1.000 controls, 😒

Just out of curiousity I used a 21.9 size & created a B/W mask for the top track, this mask would have to be dragged the length of the movie, but in VP21 this event can be left at it's orig short length & set to 'loop play' , or have i just read that somewhere else ?

If there's a choice between choosing a widescreen FX at the project FX level or using any method to mask the top video track on the timeline, the project FX approach wins hands down IMO.

Of course there are methods of doing it using looping or using an Adjustment Event (which still has to be extended out to cover the entire timeline), but surely a simple FX applied at the Project level is the most effective and trouble-free approach.

I need FX or everything is already in Vegas pro? if so can you please tell me how to proceed?

An effective and simple way is to create a project with the necessary aspect ratio; for example, 1920x920 for HD or 3840x1640 for UHD. The Vegas preview will show the actual image and then it will render as normal in 16:9 and appear with the black bars. I show it here:

In case it is of interest, I link the two veg made with VEGAS PRO 18:

1. Use a narrower screen aspect than media aspect.

--or--

2. Crop top and bottom.

Why should you render black borders when there no black borders? I do the same as you, set my project to the resolution of my desired aspect ratio. For example 2.35:1 in HD is 1920/2.35=816 (rounded). Since VP20 you can set in the editing preferences that video is automatically cropped to the project aspect ratio when added to the timeline. Rendering to 1920x816 is just a mouse click with Voukoder. Using Magix you have to create a rendertemplate with those resolutions.

For a clip with an aspect ratio of 16:9 the end result is the same whether we mask, overlay an alpha png image or render directly to 1920x816. In this case, on a 16:9 player full screen or television it will be seen with black bars. In all cases material above and below is removed by clipping or masking.

Ofcourse on a 16:9 screen both will have black bars, the difference is only that 1920x816 render doesn't spill bitrate and rendertime for black bars which a 1920x1080 masked render does.

The other thing is the expectation that every screen is 16:9, if OP looks at this video on his standard 16:9 monitor it will have black bars top and bottom, but if he opens it on a modern phone it will likely have no black bars or only very thin black bars

Even videos with ridiculously wide aspect ratios like this one will only have thin black bars top and bottom or none at all depending on the version of Ultra wide Monitor. Imagine you put a black matte top and bottom to create a 16:9 version of this video, then played it on a 21:9 or 32:9 Monitor, you would have ruined the viewing experience with giant black bars top, bottom and both sides

Okay thank's u everyones.

If not, which filter is it, please, how to proceed?

There's quite a number of suggestions that have been made using a variey of methods available within Vegas Pro - all of which will work. Go through them and maybe try each suggestion out for yourself and then decide which is best suited to your needs and for the ease of use that you prefer. One of the beauties of Vegas Pro is that there are often several ways of doing things - and its really up to each editor to decide which method that they prefer to use.
