Use a more efficient codec such as H.265/HEVC or AV1
Keep the original resolution if possible
Lower the bitrate gradually until quality starts to drop
Use variable bitrate instead of constant bitrate
Match the frame rate to the source video
Remove unnecessary audio tracks and subtitles
Compress audio to a lower bitrate if needed
Trim unwanted sections before exporting
Use two-pass encoding for better quality at smaller sizes
Reduce noise in the video before encoding
Avoid re-encoding multiple times
Export with a high-quality preset
Use hardware-accelerated encoding if available
Choose a smaller container format like MP4 or MKV
Crop black bars and unused edges
Optimize keyframe interval settings
Use efficient compression settings in your editor or encoder
