iPhone ProRes vs HEVC: Storage, Quality, and When to Use Each
If you shoot video on iPhone, you have two very different formats available: ProRes and HEVC. ProRes is designed for professional editing and maximum quality, while HEVC is optimized for smaller file sizes and everyday sharing.
This guide shows how to choose the right format for each shoot, how much storage you really need, and how to keep huge ProRes clips from taking over your camera roll.
Quick Answer: Which Format Should You Use?
ProRes
- •Best for color grading and pro edits
- •Huge files and fast storage usage
- •Requires more free space to record
- •Often needs external storage for long 4K
HEVC (H.265)
- •Great quality with much smaller size
- •Ideal for daily shooting and sharing
- •Faster uploads and backups
- •Works with most modern apps
If you are filming something you will edit heavily (commercials, music videos, short films), ProRes is worth it. For everyday content, HEVC gives you excellent quality without the storage pain.
How Big Is ProRes vs HEVC on iPhone?
Apple notes that ProRes files can be up to 30 times larger than HEVC at similar quality. That size gap is why ProRes can fill an iPhone quickly, especially at 4K.
Storage Reality Check
ProRes is made for editing, not for saving space. If you plan to record ProRes, assume you will need several times more storage than HEVC for the same amount of footage.
ProRes Recording Requirements (What iPhone Needs)
ProRes has strict requirements. Apple says you need at least 10% free storage to record ProRes. For iPhone models with 128 GB storage, 4K ProRes recording is only available at 30 fps, and 4K at 60 fps requires external storage. On newer iPhone Pro models, 4K at 120 fps ProRes also requires external storage.
If you are planning a long shoot, bring fast external storage and test your setup ahead of time.
Check free space: keep at least 10% of storage free before recording ProRes.
Confirm your frame rate: 4K 60 fps ProRes needs external storage on 128 GB models.
Use external storage for long shoots: if you need 4K 60 or 4K 120 ProRes, plan for an SSD.
Test a short clip first: verify the workflow before a full shoot to avoid interruptions.
HEVC vs H.264: Which "Normal" Format Should You Pick?
In iPhone camera settings, "High Efficiency" uses HEVC (H.265) and "Most Compatible" uses H.264. HEVC keeps quality high while reducing file size, which is why it is the best default for most people.
If you need maximum compatibility for older devices or legacy apps, H.264 is still a safe option. But if storage matters, HEVC is the better everyday format.
Pro Tip
Use HEVC for daily shooting, and switch to ProRes only when you know you will be doing professional edits that justify the storage cost.
A Simple Decision Checklist
Choose ProRes if you need
- Heavy color grading or VFX work
- Professional delivery requirements
- Maximum editing flexibility
Choose HEVC if you need
- Smaller files and faster uploads
- Everyday shooting or travel clips
- Long recording time without storage stress
The Storage Fix: Compress ProRes for Archiving
If you shoot in ProRes, you do not have to keep every clip in that format forever. Once editing is done, you can convert finished videos to HEVC and save huge amounts of space while preserving quality.
HEVCut is built for this exact workflow. Select your finished clips, compress to HEVC, and free up space without losing the look of your final edit. It is the easiest way to enjoy ProRes quality and still keep your iPhone storage under control.
