1, adjust the video resolution. If you don't need HD video, don't choose 4K or 1080p, and switch to 720p, the video won't be too big.
2. Adjust the video frame rate and reduce the frame rate from 60 to 30, which can save space.
3. Adjusting the video to "Efficient Video Format" can save about 35% space. It is a new format of H.265, and may not play normally in the old player or operating system.
