Hey @sangbpark94,
I already answered this in your last post. Expo Video Truncator Please refrain from double posting, especially if the question has been answered. If I come across means to accomplish this in a standard Expo project, I’ll be sure to let you know. If this doesn’t need to be accomplished on the client-side, you could handle it server-side with a library like fluent-ffmpeg.
Cheers,
Adam
