NOTE: The maximum allowed video size is 2000MB. In addition, the videos shouldn't be shorter than 15 seconds or longer than 360 seconds, otherwise they will be rejected.


In our research we've found that the user's concentration level drops significantly when dubbing videos longer than 360 seconds.
Also, since live dubbing is a stressful task, we limit the duration in hopes to keep a balance between the amount of speaking practice the user achieves and the frustration he/she gets along the process.
