Questions & Answers about Во время вебинара я делаю запись в блокноте.

Why is it во время, not в время?

Во is just a pronunciation-friendly variant of в. Russian often uses во before certain consonant clusters or sounds that are awkward to pronounce.

So:

• в школе
• в доме
• but во время

You should learn во время as a fixed expression meaning during.

Why is вебинара in the genitive case?

Because во время requires the genitive.

So the pattern is:

• во время урока — during the lesson
• во время встречи — during the meeting
• во время вебинара — during the webinar

The dictionary form is вебинар, and the genitive singular is вебинара.

What exactly does во время вебинара mean grammatically?

It is a prepositional phrase meaning during the webinar.

Breakdown:

• во время = during
• вебинара = of the webinar

Literally, it is closer to in the time of the webinar, but in normal English we translate it simply as during the webinar.
