okay – i see what you are trying to achieve. There are plenty of ways you can tackle this – all without changing the physical size of the video frame.
Firstly, more questions….
what is the background?
Is the man stood in front of a plain backdrop? Is he “chroma keyed”?
Is he stood centrally in the frame?
Assuming its a plain background and he is stood centrally, then you could try this….duplicate the shot and layer them directly on top of each other. On the top layer use the position tool to move the image to the left (or right) until the man is positioned where you want him. Apply a crop to the right hand edge of the frame with a feather setting to soften the crop. Blur the lower layer this will have the effect of extending the background on one side.
Alternately you could try crop the man more closely and layer him over an artificial background. How you do that is up to you – there are as many methods as there are editors using them!
Or – perhaps you could create a completely new shot by taking a photo of a TV in a suitable location, then crop and distort the man to appear as if he is in the tv screen with the text appearing elsewhere in the frame. Obviously context is important here – only you know what would be suitable for the shot. Have fun, experiment and think outside the box (pun intended !!)
One final thing to bear in mind – if this was being made to view on a tv, then widening the frame of the edit would only cause the final edit to look wrong. A tv has a specific width and height, and the image you put into it must match up otherwise your image will distort. Your tv might shrink the image to fit the width, causing the height to shrink by the same amount and thus you will have black gaps at top and bottom. Or it may scale to fit by height in which case parts of your image will get cut off at either side.
Its sensible practice to stick with the tried and tested standard dimensions, and change your composition to reflect this.
