Re-extract motion photos without losing custom metadata
❓Question🗄️Server☑️Ready
Assume the encoded-video folder has been deleted (after a backup restore, after disk failure, etc.). The motion photos will therefore not work since they're stored there.
It's my understanding that their extraction is done during the Metadata Extraction job, but if the files have simply been deleted from FS running the "Missing" stage will not work, so I have to run the job for "All". However, it's also my understanding (from having been bitten by this in the past) that doing this would also erase all custom metadata for photos that already have some EXIF info (e.g. photo taken on my phone, with EXIF date, on which I've manually modified the date afterwards, or modified the GPS location).
1. Does running Metadata Extraction on "All" still erase custom metadata on latest Immich?
2. Is running "All" like this the proper way to get motion photos back to working?
