All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
There is no objection on your production of what you called travel videos in the manner that you mentioned; hence, there is no harm on posting them on your YouTube channel to make profit from them.
If a person goes to those countries, you are not sinful for his travel if he disobeys Allah; his sin falls upon himself only. Allah Says (what means): {And no bearer of burdens will bear the burden of another.} [Quran 17:15]
Allah knows best.
