I conduct my live interviews with Streamyard.
TubeBuddy is making a difference for me with YouTube tags.
To record my daily videos, I use:
a better mic to record mp3 Blue Yeti Nano
a headset with mic for the interviews and my French online classes
a webcam for the live streams Logitech C920
simple lights from Neewer so you can see me clearly my friend my sister 😉
and I use the opensource software Open Shot video editor on my Dell laptop Inspiron 77-7786
For the thumbnails I use a free online tool with great graphics and templates called Canva together with the free app Snapseed and the app FaceTune.
