How to Rotate a Video on Mac

You recorded a clip on your iPhone held horizontally, airdropped it to your Mac, and now Finder is showing it rotated ninety degrees. Or maybe you grabbed footage from a GoPro mounted upside down and the whole thing plays inverted. Rotating a video on Mac sounds trivial, but the tool you pick determines whether you re-encode the file (losing quality), how long the export takes, and whether the rotation actually sticks when you share the file elsewhere.

This walkthrough covers four real methods: the hidden rotate command in QuickTime Player, Screenify Studio's canvas rotation, iMovie's free rotation controls, and Final Cut Pro for anyone who wants frame-accurate transforms. Each has trade-offs around quality, speed, and what happens to the metadata.

Quick Comparison

Method 1: QuickTime Player (Built-in)

QuickTime Player ships with every Mac and handles rotation through a menu command most people never notice. It writes the rotation as metadata when possible, which means no quality loss and an instant save — but this only works cleanly with .mov files and some .mp4 files. Re-encoded formats may require a full export.

Step-by-step

1. Open Finder and locate the video file.
2. Right-click the file, choose Open With, and select QuickTime Player. If QuickTime is your default, just double-click.
3. With the video open, click the Edit menu in the menu bar.
4. You will see four rotation options:
   • Rotate Left (counter-clockwise 90°)
   • Rotate Right (clockwise 90°)
   • Flip Horizontal (mirror left-right)
   • Flip Vertical (mirror top-bottom)
5. Click the one you need. The preview updates instantly.
6. If the video was upside down, apply Rotate Right twice, or use Flip Vertical then Flip Horizontal depending on whether the camera was mounted upside down or held backwards.
7. Press Cmd+S to save. If the file is a .mov, QuickTime saves the rotation as metadata almost instantly. If it is an .mp4 or .m4v, QuickTime may prompt you to export — in that case choose File → Export As and pick a resolution.

When this fails

QuickTime's rotate menu is greyed out if the file is read-only or if QuickTime cannot write to the original format. Two workarounds:

• Duplicate first: Right-click the file in Finder, choose Duplicate, then open the copy in QuickTime. Sometimes macOS file permissions block in-place edits on originals.
• Export through a new file: Use File → Export As → 1080p (or whatever matches the source resolution). This forces a re-encode but guarantees the rotation is baked into pixels, not metadata — useful if you are uploading somewhere that strips metadata (some CMS platforms do this).

What QuickTime cannot do

You can only rotate in 90° increments. If your phone recorded at a 15° tilt because it was resting on a crooked stand, QuickTime will not help — you will need iMovie or Final Cut for arbitrary angles.

Method 2: Screenify Studio

Screenify Studio treats rotation as a canvas operation rather than a metadata flip, which means the exported file plays correctly in any player, on any platform, without relying on orientation flags that some apps ignore (looking at you, older Android video viewers). It also lets you rotate by any degree — useful for fixing handheld footage that is slightly off-level.

Step-by-step

1. Launch Screenify Studio and open the project browser.
2. Drag the video file into the window, or click Import Media and select it.
3. In the editor timeline, click the video clip to select it.
4. Open the Transform panel on the right sidebar. You will see Rotation with a circular dial and a numeric input.
5. For a standard 90° fix, click the +90° or -90° preset button. For arbitrary angles (e.g., straightening a crooked horizon), type the exact degree value or drag the dial.
6. Screenify auto-reframes the canvas so the rotated video fills the frame without black bars. If you prefer the original aspect with letterboxing, toggle Fit to Canvas off.
7. Preview the result in the main viewport. Scrub through the timeline to confirm the rotation holds across the whole clip.
8. When satisfied, click Export (top-right). Pick your target resolution — Screenify offers up to 4K and preserves the source frame rate by default.
9. Choose a location and format (.mp4 is the default). Export uses Apple's Metal-accelerated encoder, so a 5-minute 1080p clip typically finishes in under 30 seconds on Apple Silicon.

Why canvas rotation matters

If you rotate using metadata alone and upload the file to a service that re-encodes without reading rotation flags (some Slack embeds, older CMS platforms, certain email clients), the recipient sees the video sideways again. Canvas rotation bakes the orientation into the pixels, so the file is visually correct everywhere.

Batch rotation

If you have a whole folder of GoPro clips mounted upside down, use Screenify's Batch Export (available under File → Batch Process). Apply the same rotation transform to every clip in the queue, then let it run while you grab coffee.

Method 3: iMovie (Free Alternative)

iMovie is free on the App Store and handles rotation through a visual cropping tool. It is slower than QuickTime for simple 90° flips but better if you need to combine rotation with trimming or color correction.

Step-by-step

1. Open iMovie from Applications (install from the App Store if it is not there — it is free).
2. Click Create New → Movie.
3. Choose No Theme and click Create.
4. Click Import Media and select your video file.
5. Drag the imported clip from the browser down to the timeline at the bottom.
6. Click the clip in the timeline to select it.
7. Above the preview window, click the Cropping button (it looks like a square with dotted lines).
8. Two rotation icons appear at the top of the preview — one curves left, one curves right. Each click rotates the clip 90°.
9. Click the appropriate icon once (or twice for 180°).
10. Click the blue checkmark above the preview to apply.
11. To export: File → Share → File, choose your resolution and quality, click Next, pick a save location, and click Save.

iMovie limitations

iMovie will not rotate by arbitrary degrees through the standard UI. There is a workaround using a Picture-in-Picture trick with a rotation slider, but it is fiddly and the preview scaling is inconsistent. For anything other than 90/180/270°, use Screenify or Final Cut.

Method 4: Final Cut Pro (Paid Alternative)

Final Cut Pro costs $299.99 one-time (with a 90-day free trial) and offers the most precise rotation controls of any Mac app. You get sub-degree precision, keyframed rotation (start level, end tilted, or vice versa), and anchor point adjustment so rotation pivots around a specific point rather than the center.

Step-by-step

1. Launch Final Cut Pro.
2. Create a new library: File → New → Library, name it, save it wherever.
3. Import your video: File → Import → Media, select the file, click Import Selected.
4. Drag the clip from the browser into the timeline.
5. Select the clip in the timeline.
6. Open the Video Inspector (top-right panel — if hidden, press Cmd+4).
7. Scroll to the Transform section.
8. The Rotation field accepts values from -360 to +360. Type the angle you need, or drag the dial.
9. For keyframed rotation (e.g., a clip that starts level and rotates as it plays), click the diamond icon next to Rotation at the start frame, move the playhead forward, and change the value — Final Cut adds a keyframe automatically.
10. To export: File → Share → Master File (default), adjust settings if needed, click Next, save.

When Final Cut is worth it

If you are editing rotated footage regularly (drone pilots, action sports, multi-cam interviews), Final Cut's non-destructive rotation plus color grading and multi-cam sync justify the cost. For one-off fixes, stick with QuickTime or Screenify.

Bonus: using ffmpeg from Terminal

If you are comfortable with a command line, ffmpeg rotates videos in a single command and is scriptable for automation. Install via Homebrew (brew install ffmpeg). To rotate 90 degrees clockwise with metadata only (no re-encode when the container supports it):

ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=90 output.mp4

For a pixel-level 90 degree clockwise rotation (required when metadata rotation is ignored downstream):

ffmpeg -i input.mp4 -vf "transpose=1" -c:a copy output.mp4

Transpose values: 0 equals 90 counter-clockwise plus flip, 1 equals 90 clockwise, 2 equals 90 counter-clockwise, 3 equals 90 clockwise plus flip. For 180 degrees, chain two transposes: -vf "transpose=1,transpose=1". This approach wins on speed for batch scripts but has no preview, so test on a short clip first to confirm direction.

Troubleshooting

"Rotation is not saving when I re-open the file"

QuickTime's metadata rotation depends on the container format. If the file is an older .avi or .wmv, QuickTime cannot write rotation metadata and the change is discarded on save. Fix: export through File → Export As to force a pixel-level rotation, or use Screenify Studio which always bakes rotation into the export.

"The video looks correct in QuickTime but sideways on YouTube"

Some upload pipelines ignore metadata rotation flags. YouTube is generally good at reading them, but Twitter, older Slack clients, and some CMS platforms are not. If you are seeing this, re-rotate the file using a pixel-level method (Screenify, iMovie export, or Final Cut export) so the orientation is in the pixels themselves.

"iMovie's rotation button is greyed out"

The clip is not selected. Click directly on the clip in the timeline (it should show a yellow border), then click the Cropping button above the preview. The rotation icons only appear when the cropping tool is active on a selected clip.

"Audio is out of sync after rotating"

Rotation should not affect audio, but if you used a re-encode method (iMovie, Final Cut, Screenify export), the export settings may have changed the audio sample rate. Check the export dialog — match the audio sample rate to the source (usually 48 kHz for camera footage, 44.1 kHz for some iPhone recordings).

"The file size ballooned after rotating"

QuickTime's Export As with default settings sometimes uses a higher bitrate than the original. If the output is significantly larger than the source, export at a specific bitrate — in Screenify, use the Export → Advanced panel to set bitrate manually, or see our guide on how to reduce video file size on Mac.

"Black bars appeared after I rotated"

Rotating a 16:9 clip 90 degrees creates a 9:16 vertical shape — if you export to a 16:9 canvas, the player pillarboxes with black bars on the sides. Two fixes depending on intent. First, match the canvas to the rotated aspect: in Screenify, the canvas auto-resizes to the rotated dimensions; in Final Cut, open the project properties and switch from 1920x1080 to 1080x1920. Second, if you want to keep 16:9 for a specific platform, zoom and crop the rotated footage so it fills the frame — you lose the top and bottom of the original shot but avoid the bars.

"QuickTime crashes when I try to save the rotation"

This typically happens with very large files (over 10 GB) or files with corrupted metadata. Workaround: rename the source file to something simple with no special characters, copy it to a local SSD (not an external drive or cloud-synced folder), and try again. If QuickTime still crashes, skip to Screenify or ffmpeg — both handle larger files without the same memory pressure.

FAQ

Q: Can I rotate a video without re-encoding on Mac?

Yes, if the file is a .mov or compatible .mp4. QuickTime Player's Edit → Rotate Right/Left commands write the rotation as metadata, which is instant and lossless. For other formats, rotation requires re-encoding, which means a slight quality drop and a longer export time.

Q: What is the difference between rotating and flipping a video?

Rotating turns the video around its center in 90° or arbitrary increments — a landscape clip becomes portrait. Flipping mirrors the video along an axis — flip horizontal swaps left and right (useful for correcting selfie videos that are mirrored), flip vertical swaps top and bottom. QuickTime and Screenify both support all four operations.

Q: Why does my iPhone video look rotated only on my Mac?

iPhone records all videos in landscape sensor orientation and writes a rotation flag to the metadata. Most modern apps read this flag and display the video correctly, but older apps or certain Finder preview modes may ignore it. Playing the file in QuickTime should display it correctly — if it does not, the metadata is wrong, and you can fix it with any of the methods above.

Q: Can I rotate only part of a video?

Yes, but not with QuickTime. Screenify Studio and Final Cut Pro both support split clips — cut the video at the point where rotation should change (Screenify: select clip, press S to split at playhead), then apply rotation only to the segment you want. iMovie also supports this through its cropping tool per-clip.

Q: Does rotating a 4K video make it take forever to export?

It depends on the codec and your Mac's chip. On Apple Silicon (M1 and later), Metal-accelerated apps like Screenify and Final Cut export rotated 4K clips at roughly real-time or faster — a 5-minute clip takes 2-5 minutes. On Intel Macs without hardware acceleration, the same export can take 10-20 minutes. QuickTime's metadata rotation is instant regardless of resolution because it does not re-encode.

Q: Can I rotate a video on iPhone and send it to Mac already fixed?

Yes. Open the Photos app on iPhone, tap the video, tap Edit, tap the Crop icon (bottom bar, third from left), then tap the rotate icon at the top-left. Each tap rotates 90°. Tap Done to save. The rotation is written into the file, so when you AirDrop or share to your Mac, it arrives correctly oriented.

Q: Will rotating a video lose quality?

A metadata rotation (QuickTime on a .mov) is 100% lossless — the pixels are unchanged. A re-encode rotation (any app that exports a new file) will lose a small amount of quality because H.264 and H.265 are lossy codecs. For most viewers, this loss is invisible if you export at a high bitrate. Use ProRes or a bitrate above 20 Mbps for 1080p if quality matters.

Q: How do I rotate a screen recording on Mac?

Screen recordings rarely need rotation since they match your display orientation, but if you need to rotate one (e.g., you recorded a vertical iPhone mirror), any method in this guide works. For recordings made specifically for vertical display (TikTok, Reels), it is better to record in the correct aspect from the start — see how to record your screen in 4K on Mac for capture settings.
