Convert AAE to MP4

A video editor, browser, television, or media player may require MP4, while an AAE file cannot be played or encoded as video. The required workflow is to recover the edited photo or original video associated with the AAE, then export or encode that media as MP4.

What the AAE format is

An .AAE file is an Apple Photos sidecar containing XML-based instructions for edits such as cropping, exposure changes, and filters. iPhones, iPads, and Apple Photos can create it beside an original JPEG, especially when edited photos are transferred to a computer.

AAE contains edit metadata, not the original image or video pixels. It is not an Adobe After Effects project; After Effects projects normally use the .AEP extension. Renaming photo.AAE to photo.MP4 cannot create playable media.

The AAE must remain beside its matching original, with the same base name, for example IMG_1234.JPG and IMG_1234.AAE. A text editor can display the XML, but the edit instructions are generally not useful for reconstructing the image with non-Apple software.

What the MP4 format is

MP4 is a multimedia container supported by browsers, phones, televisions, editing applications, and social platforms. A compatible MP4 commonly contains H.264 video and AAC audio; yuv420p pixel format and the +faststart option improve compatibility and web playback.

MP4 is appropriate when the source is a video, such as an iPhone .MOV file. If the AAE belongs to a still photo, the result is not a recovered video: it is a new video containing the rendered image, usually displayed for a selected duration and optionally combined with audio.

How to create an MP4 from an edited photo

1. Find the original JPEG and keep its matching AAE sidecar in the same folder. If the original image is missing, the AAE cannot supply it.
2. Render the edit with Apple Photos. On the original iPhone or iPad, open the edited photo and share or save the displayed result. If the photo already exists in a Mac Photos library, select the edited version and use File → Export → Export 1 Photo. Export it as a JPEG, such as edited.jpg.
3. If you only have a JPEG and AAE copied from another device, importing both into Photos may not apply the sidecar because AAE handling depends on the Apple Photos library and device that created the edit. If the imported image appears unedited, use the original Apple device or its Photos library to export a rendered copy; no general-purpose converter can reliably interpret every Apple adjustment.
4. Import edited.jpg into iMovie, set the image duration, and use File → Share → File. Choose a suitable resolution and quality, then export the MP4. The still image produces no audio unless an audio track is added.

FFmpeg provides a local command-line alternative. This command creates a five-second, 30-frame-per-second MP4, scales the image without distortion, and pads it to 1920×1080:

ffmpeg -loop 1 -i edited.jpg -t 5 -r 30 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2,format=yuv420p" -c:v libx264 -movflags +faststart output.mp4

Change -t 5 to the required duration. Remove the fixed scale and padding if the destination accepts the image's native dimensions, but H.264 requires even frame dimensions.

How to convert the associated video

Do not use the AAE as the input. Locate the original video, normally an iPhone .MOV file, and export either the edited rendition or the unmodified original from Photos. The exact export labels vary by platform, but Mac Photos provides options under File → Export, including Export Unmodified Original.

For a local conversion, HandBrake can encode the exported video with an H.264 MP4 preset such as Fast 1080p30. FFmpeg provides more control:

ffmpeg -i input.mov -c:v libx264 -c:a aac -movflags +faststart output.mp4

Set a video frame rate, resolution, and bitrate appropriate to the destination when the defaults are unsuitable. If the source has no audio, the output will also have no audio unless a separate track is added.

Online conversion options

CloudConvert and Zamzar can convert a source video such as .MOV to MP4 through a browser. Upload the original or rendered media, not the .AAE file; these services cannot apply Apple sidecar instructions or recover missing media. Online conversion requires uploading personal photos or videos, so iMovie, HandBrake, Photos, and FFmpeg are preferable for private material.

Quality and compatibility limits

An AAE file contains no pixels, frames, audio, or independent copy of the original. If the matching JPEG or video is gone, conversion is impossible. If the AAE only records edits that were never rendered by Apple Photos, those adjustments may be lost.

Exporting an edited photo to JPEG renders the Apple adjustments but may introduce JPEG compression; converting that JPEG into MP4 adds video encoding. Keep the original media and AAE if future editing is required. For broad playback support, use H.264 video, AAC audio, yuv420p, and MP4 fast-start metadata.
