[Bug ]Very large XMP Metadata file embedded in MP4 and MOV
Premiere & Media Encoder in some cases embedds XMP files into .mov and mp4 containers.
I have just exported a sequence (SD) to a .mp4 with 3 Mbit/s.
Estimated file size was 21 MB. Final file size was 106 MB.
Exported to Quickime .mov with Cineform codec. File size should be about 219 MB, final result was 305.
Encoded the MOV to MP4...final file still 106 MB.
Demuxed the .mp4, then muxed it again to .ts file, encoded with Media Encoder to .mp4, final file was 21 MB.
So I encoded the file without muxing from Premiere, and it created an 85 MB .xmp file, along with the .aac and .m4v.
I then checked the Metadata settings, they were set to sidecar file.
Set it to none... and the sequence exported fine as .mp4 with a file size of 21 MB.
An 85 MB .xmp file seems a little bit too large.

Sorry to hear this. There's no way to disable XMP ? Why are they so big what do you have inside ? Would you send me some samples ?
Otherwise you can use AfterCodecs https://autokroma.com/AfterCodecs/ you won't have XMP embedded and it supports H264 in Quicktime MOV / MP4
I'm having the same problem and its a major issue at my work. We don't want to post 118 MB files to the web for a client to review when Media Encoder is claiming it will be 18 MB!
As a test as soon as I turn off the sidecar file I get the 18 MB file. Media encoder needs a warning or something to tell us that the 18 MB is only if the XMP/sidecar is turned off. It's very misleading, tremendously frustrating and a huge waste of time. Please look into asap. Thanks
I'm having the exact same problem. Anyone else encounter this/find a solution?
