I use the Sony Vegas Pro 14 (64-bit) and I made a video edit which included a whole lot of effects, everything went well and smooth until the last 5 frames. The overlay that I had wasn't masked according to what I had edited in the first place, same as the last frame, where I included the optical flare effect. Now, in the actual program, it plays well, just as I had edited it, but after I rendered it, the aforementioned overlays and effects weren't as pleasing as it had looked before. What do y'all suggest that I should do?
