Set fixed resolution for video in cloud recording

hello there, i am working on video processing with zoom cloud video recording files as input. need helps about following inquiries:

  1. how zoom define video resolution on recording files?we have multiple zoom account from multiple clients and got inconsistent recording resolutions. some video have 1920x1080 but there are also videos with 2560x1440. need help what factors can lead the recording into different video resolution.

  2. is there any way to set fixed video resolution for cloud recording files programmatically (API Based) or manually? for example, i want have max resolution for recording at 1920x1080. what i can do to apply this programmatically for all accounts?

thanks in advance.
