Premiere Pro CC 2015 and I have not had such a smooth existence. For some reason, Premiere will playback fine with no dropped frames, and then after about 10-15 seconds it starts dropping frames. This typically starts at the beginning of a new clip, and then continues to the next. This happens far less frequently when color correction isn't applied, such as MBL 12 (not gpu accelerated) or even Lumetri (gpu accelerated), however, on occasion it does still happen. I've checked my processes and the CPU, RAM, or VRAM are not saturated. Now the kicker is, all I have to do to stop the lag is to press space to stop playback, and again to start again.
System specs: i7 3930k, 32gb DDR3 1600, GTX 980ti 6GB VRAM, SSD for Premiere, HDD for cache files and media for the project
Files: ranging from ProRes, .mxf, DNXHD, .etc.
I figured it could be the following scenario:
audio related? I've had a situation before where an audio effect (not applicable to this question) actually brought my timeline to a halt w.r.t. playback
loading up different codecs on the same timeline (hence this happens at the start of a single clip and then bogs down the timeline)
HDD isn't fast enough, replace with SSD
Has anyone experienced anything similar, and perhaps can help me find a solution?
