Spinach isn't currently optimized for in-person or conference style meetings but we have a recommended workaround below:
To ensure each individual contributor is recorded, add all the individuals who are in person to the meeting invite (with a video link included) and have at least 1 person join the video link with Spinach.
You can use the edit summary feature for in-person meetings, conference meetings or meeting rooms. Using the edit feature can help you assign the correct speakers to each item. Upgrade your account to the Pro plan here to get access to this feature and more.
Spinach only records up to 4 hour meetings, so if you have a day-long event, we recommend breaking it up into smaller calendar events with Spinach invited to each event.
