I'm going to need a bit more information here. What is the code you're using? Do you have a reproduction project that you can show for this? What do you mean by "uploaded from the device to the application"?

Code fragment: private async Task pickVideo() { try { var file = await MediaPicker.PickVideoAsync(); var filePath = await loadFileResultAsync(file); if (filePath == null) return; _filesAction(new List<IFileWrapper> { new FileInfoFileWrapper(new FileInfo(filePath)) }); BindModalItem(); _onDialogClosed(null); } catch (Exception e) { UserDialogs.Instance.Alert("Unable to select video at this time"); ApplicationViewModel.Current.SendUserEvent(e); } } problem scenario I have my app open on my iPhone or iPad and I want to upload a video to my app and then save it to a database. The video I load is named "video_2022.mp4". When I add the video to the ListView and save to my database the name is trim.D823445678-DF01-345.mov I have noticed that this happens in the process of converting mp4 to mov, but I need to find to keep the name of the file loaded.

What does loadFileResultAsync do? Is the filename correct right after await MediaPicker.PickVideoAsync();?

Based of this snippet it's still hard to say if this is anything caused by Essentials

@jfversluis Bumping this issue because I'm currently facing this.

To give a quick summary about this issue, this is basically happening on iOS devices when using await MediaPicker.PickVideoAsync();.

Based on what I've seen, the selected video is copied into a temp folder, with a new temp file name. Example of the FullPath property of the FileResult after picking a video: "/private/var/mobile/Containers/Data/PluginKitPlugin/9161A3A2-2BEE-4DB4-A47B-1EF426370247/tmp/trim.3C339653-B9EB-4022-B5A1-96F42656C488.MOV".

The new copied file is prefixed with "trim." and a new Guid as its file name. The original file name is lost.

An indication on what might be happening is that when picking a video, the OS will start to compress the video, possibly copying it along the way, and then returning this new compressed file instead of the original.
