The problem with Shadow Play

Hey. Anyway, I bought a new laptop with a graphics card from NVIDIA,namely the GeForce GTX 1050Ti. Set a 10-second Windows, updated all drivers, all is well. Installed GeForce Experience, there are also all drivers updated, everything is fine, Shadow Play set up, decided to shoot something and are faced with the problem that if the option to put a sound recording on one track, with a sound LIKE everything is in order, but with a video problem. A two-minute video takes 10 seconds, some kind of epilepsy is happening. And if you put a sound recording on two tracks, the microphone perfectly written, and the system (game) sounds are recorded jerks,as if you quickly then turn the sound off (by the way, the MIC is heard only with the standard player windows and game sounds only heard from third-party players) on the Internet said to throw in Vegas and process, but when you add the video from sabhi Vegas krašit. Please help. Driver all right, the version of the program, on the system requirements it fits. Please do not write something of type: download a different program etc. I Hope for you.
