Trimming your video
Let's say you want to trim your video.
Go to the asset you wish to edit.
In the URL bar, after the asset URL, type
#t=STARTTIME,ENDTIME, replacingSTARTTIMEandENDTIMEwith your desired start and end times. Make sure to add a comma between the start time and end time.
For example, to trim the video from 8 seconds to 1 minute and 19 seconds, you would type #t=0.08,1.19
