I have rendered several relatively long animations at 720x480. There is one particular software program I need to use to view it, but when it’s full-screen the aspect ratio doesn’t match that of the typical computer screen so I’m getting some vertical stretching.
Basically, I need to add black bars at the top and bottom so they are 720x540. Fortunately, I rendered the animations out as jpgs for each frame, making it easy to stick them into the sequence editor and re-encode/re-render them as needed. Does anyone know if I can actually use Blender to add those black bars?
