expo-image-picker returns videos in .MOV format on iOS even when videos are in MP4 format

Hello and thanks for reporting,
I'm going to post a workaround that should keep the video format as-is:

(1) specify videoExportPreset in options, with the value Passthrough

(2) read the result from uri, as seen in this image

edit: this is for a mov file. See below for mp4 file

We're going to provide an improved solution - use the workaround in the mean time.

How this works: in transcodeVideoAsync this will return the vide url unchanged - so whatever file you select, it'll return its copy without transcoding it.

Thank you 🙂

Hello @vonovak ,

Thank you very much for taking the time to respond and for replicating the issue I'm experiencing. However, I noticed that in your response, while the filename is in .mp4, the URI is still in .mov format. My expected behavior is for the URI to also be in .mp4 format, matching the format selected from the library

Thank you again for your help

Hello, apologies, the above screenshot was for a mov file. The one below is for an mp4 file.

So the provided workaround should work.
