Awful/ unusable video performance

Post by Haavard » Fri Feb 09, 2018 4:16 pm

I have just imported a 1080 H.264 .mov file into a so far pretty lightweight project. 6 - 7 tracks of EW Play and some HALion tracks.

And the performance is awful. Unusable. It plays for about 3 seconds, then a stutter turns into a freeze.
No audio glitches. Increasing latency doesn't help.

The funny thing is, I can run MPC or another program playing the exact same video file SMOOTHLY while CUbase is playing back my project. This is exasperating!

(Some specs: i7 920 (1st gen), 16 gb ram, Nvidia GT740. Steinberg UR28M Latest Cubase Pro 9.5, latest HALion, latest EW Play)

Hi,

Maybe Nvidia is the problem. Try to upgrade to the latest Nvidia driver. If it doesn't help, try to downgrade to 373.06 driver, please.

No, didn't help.

And, as I said, I can play the same video file when Cubase is running, and it plays with no issues whatever. So my computer's performance is not the issue here. Rather Cubase/ Cubase's video engine.

It play smoothly for about two seconds, then freezes, and doesn't unfreeze until I hit pause.

What video codec do you use, and where (what application) was the video made?
