Wrong video height and width

[OscarDaSilva]

Hello,

I implemented this plugin in my app. I have a video with 1080x1920 resolution and 88,6MB in my iOS emulator gallery.

When I process the video, it is transformed to 320x568 and 5,2MB

The file is picked with FilePicker.pickMedia() and I tried multiple TranscodeOptions but Im not able to keep the 1080x1920.

VideoEditor.edit({
path,
transcode: {
width: 1080,
height: 1920,
keepAspectRatio: true,
fps: 30,
},
})

Can you maybe help me? Thanks.

Can you send me an example video that shows this problem?

Si mira aquí tienes el video: https://s3.spacemedia.es/ScreenRecording_07-31-2025%2008-42-27_1.mp4

Este es más pequeño, 529x1280, pero igualmente me lo convierte a 224x480.

Estas son las únicas opciones que uso, no hago nada más:

const transcodeOptions = {
width: 1080,
height: 1920,
keepAspectRatio: true,
fps: 30,
};

Con este video he tenido otro problema, el nombre tiene un espacio y el path que se le manda al VideoEditor.edit() ya lleva el encoding y traduce el espacio a %20. En el VideoEditorPlugin línea 41 al pasarle el path a URL() vuelve a hacer un encode y codifica el símbolo del %, quedando el path erróneo con %2520. El archivo lo selecciono con FilePicker.pickVideos();

Todo esto es en iOS, en Android no he tenido problema.

Gracias.

The problem is with the FilePicker plugin, which uses UIImagePickerController and compresses the video before return it.

// File ios/Plugin/FilePickerPlugin.swift
let videoPicker = UIImagePickerController()
videoPicker.delegate = self
videoPicker.videoExportPreset = AVAssetExportPresetHighestQuality // <------ add this line and `import AVFoundation`
videoPicker.sourceType = .photoLibrary
videoPicker.mediaTypes = [kUTTypeMovie as String]

I'll try to post an updated version this week.

Hello,

Thanks for it, I use the @capawesome/capacitor-file-picker but I checked the code and does the same as your plugin. So I will swith to your plugin and test it. Did you also notice the problem with the spaces in the file name?

// @capawesome/capacitor-file-picker 
// File [capacitor-plugins](packages/file-picker/ios/Plugin/FilePicker.swift)
let picker = UIImagePickerController()
picker.delegate = self
picker.mediaTypes = ["public.movie"]
picker.modalPresentationStyle = .fullScreen
self.presentViewController(picker)

I'll try to review it when I get back from vacation.

I had a similar issue, so I am forcing iOS to always give back a 720p video with ~2MB bitrate with the following hack in SimpleSessionExporter.swift:

// Export
guard
  let export = AVAssetExportSession(
    asset: composition,
    presetName: AVAssetExportPreset1280x720)
else {
  print("Cannot create export session.")
  completionHandler(.failed)
  return
}

// --- IMPROVED MAGIC CODE ---
let seconds = CMTimeGetSeconds(composition.duration)
if seconds > 0 {
  // 2Mbps = 250,000 bytes per second
  // We add a 10% buffer to account for audio and metadata overhead
  let bitrateBytesPerSecond: Double = 250000
  let buffer: Double = 1.1
  let limit = Int64(seconds * bitrateBytesPerSecond * buffer)

  // Safety check: Don't set a limit smaller than 1MB
  export.fileLengthLimit = max(limit, 1024 * 1024)
}
// ---------------------------

Otherwise, iOS would always decide on bitrate and size by itself...
