Multicam Sequence with 2hr + material

[ZYRKUS26260657dybl]

I try to edit a multicam sequence with 8 different cameras. Each of them has a 2hr+ video clip. 

I already created proxies and disabled all the audio tracks. 

But I still can't edit it bc it has massive lags. Can somebody help me?

To help troubleshoot, we’ll need a bit more information about your setup:

1. Computer Specs: CPU, RAM, GPU, and storage type (SSD or HDD).
2. Original Footage: Codec, frame size, and frame rate.
3. Proxy Footage: Codec, frame size, and frame rate.
