To say "video teaching" in Engpsh, you can use the phrase "video tutorial" or "video lesson." For example, you might say:
"I'm looking for a video tutorial on how to use Photoshop."
"I learned a lot from the video lesson on Engpsh grammar."
You could also say "video-based instruction" or "onpne video course."
I hope this helps! Let me know if you have any other questions.
