I have some problem. I’m making a lightsaber fight scene, frame by frame with compositor for glow effect. Everythink was great, I spent few hours today on making first 170 frames, after render everythink looking great, but I needed to make a break. When i came back, and reopen Blender and the file, something went wrong. About half of frames don’t match each other (sabers with video) and I have no idea why. Few frames are OK, then few not, and then again few ok, etc. I checked older saves, and the same problem is in all of them, from first to last. Any idea what did I do wrong? Is this some kind of bug or something?
