Place of record vs bandwidth

Dear Zoom,

we plan to organize a large meeting, but limited bandwith is available for the host. Nevertheless, we intend to record the meeting. From bandwith point of view, which is more favorable - recording to the computer of to the cloud?

What I'm asking is basically a technical question: if we choose to record the meeting to the cloud, as a first step the software downloads all the data to the computer then uploads to the cloud (2x data transfer), or sends it directly to the cloud (leading to no extra data transfer to the host)?

Thank You for Your answer in advance!
