Common Video Compression Mistakes
- Overcompressing multiple times: Compressing an already heavily compressed video degrades details irreversibly.
- Using high-bitrate containers on the web: Embedding MOV files on blogs causes page lag. Always use WebP/WebM for websites.
- Incorrect Aspect Ratio: Changing resolution without locking proportions causes stretched faces or letterboxing.
Pro Tips for Video Optimization
- Downscale resolution first: Changing a video from 4K to 1080p saves up to 70% in size before bitrate compression runs.
- Target H.264/MP4: Use this container if sharing on WhatsApp or email to guarantee playback on client devices.
- Trim non-essential segments: Use trimming tools to crop off empty intros or endings to save bytes.
