I rendered a video and i realized one frame was not being displayed as it is supposed to. I used the eraser on part of it but it renders as if the part was still there. I checked and rechecked back at my project and the part is correctly erased, I even both previewed and ram previewed and the frame shows fine only when i render the composition it shows wrong. Why?? This blows my mind at so many levels. Isnt the RAM preview supposed to show the video exactly as it is going to look after rendering it?
