Yulian, please do not be offended. We are here to help.
Many of us are using computers within sensitive organizations where computer safety has to be observed.
I noticed that there is a way to import your video from your computer to the Forum.
You can also post the video on YouTube and link it using the same function.
The forum will also let you cut and paste images from a "snipping tool"
Please expand on your question so we may understand how we can help.
