I'm editing a split screen project with Avid Media Composer. I've used the simple "resize" effect to have three small images simultaneously side by side on my screen. Everything worked nicely until last night some of the images became heavily blurred. These are random images here and there, not depending on the speed changes or other effects used. When I used "match frame" to go back to original clips, they are totally ok. Any idea where this random blur might come from? I didn't change any settings when this occurred. Thanks!
