How to compress 1080p video under 100MB using FFmpeg without quality loss

Are you struggling to reduce video file size without losing quality? This comprehensive guide shows you how to compress 1080p video under 100MB using FFmpeg, the most powerful open-source video processing tool. Whether you are dealing with large raw files, high bitrate 1080p footage, or videos that are too big for Discord, WhatsApp, or Email, we walk you through the exact FFmpeg commands to optimize your video. This step-by-step solution helps you master video compression using H.264, H.265 (HEVC), and Constant Rate Factor (CRF) settings to achieve the perfect balance between file size and visual clarity while maintaining 1080p resolution.

In This Video We Will See How to Compress 1080p Video Under 100MB Using FFmpeg Without Quality Loss

Here Are The Steps to Compress 1080p Video Under 100MB Using FFmpeg

Method 1: Using CRF (Constant Rate Factor)

1. Open your terminal or command prompt
2. Navigate to the folder containing your video
3. Type: ffmpeg -i input.mp4 -vcodec libx264 -crf 23 output.mp4
4. Press Enter
5. Wait for the process to finish
6. Check the file size
7. Done!

Method 2: Target Size Calculation (Two-Pass Encoding)

1. Open your terminal or command prompt
2. Calculate the required bitrate for 100MB based on video duration
3. Type: ffmpeg -y -i input.mp4 -c:v libx264 -b:v 1M -pass 1 -f mp4 NUL (or /dev/null for Mac/Linux)
4. Type: ffmpeg -i input.mp4 -c:v libx264 -b:v 1M -pass 2 output.mp4
5. Press Enter
6. Wait for encoding to complete
7. Done!

Method 3: High Efficiency (H.265/HEVC) for Smaller Files

1. Open your terminal or command prompt
2. Type: ffmpeg -i input.mp4 -c:v libx265 -crf 28 -tag:v hvc1 output.mp4
3. This codec provides much better compression than H.264
4. Press Enter
5. Wait for the high-efficiency render
6. Verify file size is under 100MB
7. Done!

Method 4: Reducing Audio Bitrate to Save Space

1. Open your terminal or command prompt
2. Type: ffmpeg -i input.mp4 -vcodec libx264 -crf 24 -acodec aac -b:a 128k output.mp4
3. This compresses both video and audio for maximum savings
4. Press Enter
5. Wait for processing
6. Done!
