Fitting under upload limits
Email attachments usually cap at around 20–25 MB and chat apps have their own limits. Scaling 1080p down to 720p plus a quality of 50–55 typically cuts an MP4 by 60–80%.
Phone footage is often recorded at very high bitrates, so recompression alone saves a lot even at full resolution.
