| Technique | How It Works | Impact on File Size | Impact on Quality | | :--- | :--- | :--- | :--- | | | A more efficient 'language' for encoding video data. | Very High (25-50% reduction vs H.264) | Low to None (Better efficiency means quality can be retained longer). | | Lower Bitrate | Reduces the amount of data used for each second of video. | Extreme (Primary driver for <100MB files) | Very High (Results in blockiness, blurring, and loss of detail). | | Lower Resolution | Reduces the number of pixels in the video (e.g., 1080p to 240p). | Extreme | Very High (Video will be small and pixellated on large screens). |
If the file ends in .exe , .scr , .bat , or .zip / .rar (requiring a password to open), do not run or extract it. Inspect the File Properties download highly compressed movies under 100mb work
This process removes data that the human eye might not immediately notice, though at 100MB, artifacts like "blockiness" in dark scenes become very apparent. Recommended Tools for Compression | Technique | How It Works | Impact
Ensure the file ends in .mp4 or .mkv . Avoid .exe or .apk files masquerading as movies. | Extreme (Primary driver for <100MB files) |
