iPhone records video in HEVC or H.264, depending on your model and settings

iPhones record video in one of two formats: HEVC (High Efficiency Video Codec, also called H.265) or H.264 (also called AVC). Which one your phone uses depends on your iPhone model and what you chose in settings. HEVC is newer and smaller — the same video takes up roughly half the storage — but H.264 plays on older devices and older editing software without conversion. Most iPhones from iPhone 11 onward default to HEVC. Older models use H.264.

The file itself is wrapped in a container called MOV (QuickTime format). So when you record a video on your iPhone, you get a .MOV file containing either HEVC or H.264 video inside it. This matters because some editing software reads MOV files but not the HEVC codec inside them, which means the file won't open even though the container format looks right.

Key Takeaways

  • iPhone videos are .MOV files containing either HEVC or H.264 video codec, with HEVC being the default on newer models and taking up roughly half the storage space.
  • You can check which codec your iPhone is using by going to Settings > Camera > Formats and looking for "High Efficiency" (HEVC) or "Most Compatible" (H.264).
  • Older editing software like some versions of Adobe Premiere or Final Cut Pro may not read HEVC files directly, so switching to H.264 in settings solves playback problems without converting files.
  • If you need to convert an HEVC video to H.264 or MP4 for a specific editor or platform, free tools like HandBrake or iMovie can do this on your computer.
  • YouTube, TikTok, and most social platforms accept both formats, but some older devices or streaming services may require H.264 or MP4 instead.

How to check what codec your iPhone is recording in

Open Settings on your iPhone, then go to Camera. Tap Formats. You will see two options: "High Efficiency" and "Most Compatible". High Efficiency means your phone is recording in HEVC. Most Compatible means H.264. The setting applies to all video you record going forward, but does not change videos you already shot.

If you are not sure which setting you are currently using, look at a recent video file on your computer. Right-click the .MOV file, select Properties (Windows) or Get Info (Mac), and look for the codec listed under Video. It will say either HEVC or H.264. On a Mac, you can also open the file in QuickTime Player, go to Window > Show Movie Inspector, and see the codec there.

When to use HEVC and when to use H.264

Use HEVC (High Efficiency) if you are recording a lot of video and storage matters. A 10-minute 4K video in HEVC takes roughly 1.5 GB; the same video in H.264 takes 3 GB. If you edit on a Mac with Final Cut Pro 10.4.1 or later, or on Windows with DaVinci Resolve, both read HEVC natively. Adobe Premiere Pro on Windows does not read HEVC directly, though Premiere on Mac does.

Switch to H.264 (Most Compatible) if you edit on older software, share videos with people using older devices, or upload to platforms that have had issues with HEVC. Some older Android phones, Windows tablets, and streaming devices do not play HEVC smoothly. If your editing software says it cannot open your .MOV file, switching to H.264 in settings and re-recording is faster than converting existing files.

Converting iPhone videos from HEVC to H.264 or MP4

If you have already recorded videos in HEVC and need them in H.264 or MP4 format, you have several options. iMovie (free on Mac and iPad) opens HEVC .MOV files and exports them as H.264 MP4 files. Open the video, click File > Export, choose 1080p or 4K, and save. The export takes a few minutes depending on length and resolution.

HandBrake (free, Windows and Mac) is faster for batch converting multiple files. Drag your .MOV files into HandBrake, choose H.264 as the codec, set the quality (use RF 18 to 22 for good quality), and click Start. HandBrake processes the conversion in the background. For a single 10-minute 4K video, expect 5 to 15 minutes depending on your computer.

On Windows, DaVinci Resolve (free version available) also reads HEVC and exports to H.264 MP4. On Mac, Final Cut Pro reads HEVC natively and can export to H.264 if you need it, though exporting is usually unnecessary since Final Cut works with HEVC directly.

What platforms accept HEVC versus H.264

YouTube accepts both HEVC and H.264 in MOV, MP4, or other containers. TikTok, Instagram, and Facebook all accept both. However, some older devices or browsers may struggle with HEVC playback. If you are uploading to a platform and viewers report the video will not play, the issue is usually HEVC on their end, not yours — they need a newer device or browser.

Vimeo, Dropbox, and Google Drive all handle HEVC without issue. If you are sending a video to someone and they cannot open it, ask what device they are using. If it is an older Android phone, older Windows tablet, or older smart TV, converting to H.264 MP4 solves the problem. Most devices made in the last five years play HEVC fine.

Why iPhone uses MOV instead of MP4

MOV and MP4 are actually the same container format — MOV is Apple's name for it, MP4 is the standardized name. The difference is just the file extension. A .MOV file and a .MP4 file containing the same HEVC or H.264 video are functionally identical. Apple uses .MOV by default because it is the traditional QuickTime format on Mac and iOS.

If you need to rename a .MOV file to .MP4 for compatibility with a specific program, you can do that — just right-click the file, select Rename, and change the extension. The video codec inside does not change, only the label. However, some older software may still refuse to open it if the codec is HEVC, so renaming alone does not solve codec problems.

Storage and quality trade-offs between HEVC and H.264

HEVC saves roughly 50 percent storage compared to H.264 at the same quality. A 1-hour 4K video in HEVC is about 9 GB; in H.264 it is about 18 GB. If you record a lot of video, HEVC is worth using. If you rarely record or have plenty of storage, the difference does not matter much.

Quality is identical to the human eye at the same bitrate — HEVC just compresses more efficiently. You will not see a visible difference between an HEVC and H.264 video shot on the same iPhone at the same resolution. The trade-off is purely storage versus compatibility. Newer devices and software favor HEVC; older ones need H.264.

Frequently Asked Questions

Can I edit HEVC video in Adobe Premiere Pro on Windows?

Not directly. Premiere Pro on Windows does not read HEVC natively. Convert the file to H.264 MP4 using HandBrake or iMovie first, then import the converted file into Premiere. On Mac, Premiere Pro does read HEVC, so no conversion is needed.

Will my iPhone video play on an older Android phone?

It depends on the Android phone's age and the codec. If your video is H.264 MP4, most Android phones from the last eight years will play it. If it is HEVC, older Android phones (before 2017) may not play it. Check the Android phone's specs or test with a short video first.

Should I change my iPhone to H.264 if I am not sure what I need?

If you edit on a Mac with Final Cut Pro or DaVinci Resolve, keep HEVC — it saves storage and both programs read it. If you edit on Windows with Premiere Pro or send videos to people with older devices, switch to H.264. You can always change it back later.

Does converting HEVC to H.264 reduce video quality?

No, not if you use the right settings. HandBrake and iMovie both preserve quality during conversion — they are just re-encoding the same video data into a different codec. The visual quality stays the same; only the file size changes.

What if a website says it does not accept MOV files?

Rename the file from .MOV to .MP4 (right-click, Rename, change the extension). If the website still rejects it, the issue is probably the HEVC codec inside, not the container. Convert to H.264 MP4 using HandBrake or iMovie, then upload the converted file.
