How to Reduce File Size in Adobe Premiere Pro CC (2022)
Premiere Pro
Quality matters, but so does file size. A 10-minute video exported at maximum quality can easily be several gigabytes. That is fine if you are archiving a master copy, but if you are uploading to YouTube, sending to a client, or sharing over email, you need something more manageable. The key is finding the right balance between visual quality and file size.
Premiere Pro gives you a lot of control over this during export. Most of the time, you can cut the file size dramatically without any visible loss in quality. Today we are going to go over how to reduce file size in Adobe Premiere Pro CC.
How to Reduce File Size in Premiere Pro
Opening the Export Settings
- With your sequence selected, press Ctrl+M (Cmd+M on Mac) to open the Export Settings dialog.
- The default preset is usually set to Adaptive Bitrate, which can produce files up to 750 MB per minute. That is way more than most projects need.
Choosing a Better Preset
- Click the Preset dropdown and change it to Match Source - High Bitrate or a similar preset. This is a better starting point because it matches your source resolution and frame rate while using a more reasonable bitrate.
Adjusting the Bitrate
- Click on the Video tab in the export settings.
- Scroll down to the Bitrate Settings section. This is where the biggest file size savings come from.
- Change the Bitrate Encoding to VBR, 2 Pass if it is not already set. Two-pass encoding analyzes the footage first and then allocates bitrate more efficiently. The file ends up smaller at the same quality level.
- Lower the Target Bitrate to around 5 to 8 Mbps for 1080p content. YouTube recommends 8 Mbps for 1080p, so staying in that range keeps quality high while cutting file size significantly.
- Set the Maximum Bitrate to about 1.5x your target. So if your target is 6, set the max to about 10. This gives complex scenes (lots of movement, detail) a bit more room while keeping simple scenes lean.
Adjusting Resolution
- If you filmed in 4K but your delivery platform is 1080p, change the output resolution. Under the Video tab, uncheck Match Source and set the width to 1920 and height to 1080. Downscaling from 4K to 1080p alone cuts the file size by roughly 75%.
Quick Reference
| Resolution | Target Bitrate | Typical File Size (10 min) |
|---|---|---|
| 4K | 30-40 Mbps | 2-3 GB |
| 1080p | 8-12 Mbps | 600 MB - 1 GB |
| 1080p (web) | 5-8 Mbps | 375-600 MB |
| 720p | 3-5 Mbps | 225-375 MB |
Tips
- YouTube and streaming platforms re-encode your video anyway. They compress it further on their end, so uploading a massive file does not necessarily mean better quality on the platform. A well-encoded 8 Mbps file often looks the same as a 40 Mbps file after YouTube processes it.
- Use H.264 for broad compatibility. It produces small files with good quality and plays on virtually everything.
- Use H.265 (HEVC) for even smaller files if your delivery platform supports it. H.265 produces roughly the same quality at about half the bitrate of H.264.
- Audio bitrate matters less. Audio is a tiny fraction of the overall file size. Dropping it from 320 kbps to 192 kbps saves almost nothing. Focus on video bitrate instead.
There you have it. A few tweaks in the export settings and you can cut your file size dramatically without sacrificing the quality your audience sees.
