You can submit all 200 video request tasks at the same time. GoEnhanceAI handles the queueing logic and starts executing them in rapid fashion 2-at-a-time, in sequential order based on creation time.
The first 2 videos finish in 5 minutes and the 3rd and 4th videos begin generating. They finish in 15 additional seconds.
All 200 videos are complete within 5 hours (5 minutes x 200 videos / 3 concurrency).
There is no maximum requests-per-minute limit, as long as your requests are within your maximum daily generations limit.
