I have a similar problem. Running the first project in the tutorials area, the guy firing the assault rifle. Everything is working fine until I add the Auto Levels, then the playback lags, the muzzle flash is not seen and the last moments of the clip are skipped. If I use brightness and contrast to correct the lighting differences the clip runs just fine, curious.
I have the project template at 1080p 29.97 and the frame rate at 29.97.
My system stats are:
AMD FX-8150 eight core processor 3.6 GHz
16.0 GB Ram
64 bit OS
GeForce GTX 560Ti with 1024 MB fixed
Any suggestions would be most appreciated, thanks.
