Im looking for a program that will allow me to change the aspect ratio of DV video files. When i record in 16:9 with the DV cam and play back on PC the image is desplayed as 16:9 - correctly. I can edit it in Studio 9 preserving the 16:9 flag but i want a program that allows me to letterbox the 16:9 to 4:3 so i can put it on tapes for people that dont have a widescreen TV. I would also like to take 4:3 material and "sidebox" this to 16:9 so it can be shown properly on a widescreen TV and used allong side 16:9 material in an edit. Studio 9 does not allow you to mix/change aspect ratios so i need something that can do this before editing. Any ides? Thanks, Stuart.
