Post subject:  Adding metadata to existing MXF files

Hi,

I have a situation where I would like to add additional metadata fields to MXF files generated by a Panasonic P2 camera en-route to an Avid MC. The files are DVCPRO HD, OP-Atom.

Is it possible to insert meta-data elements without having to touch the essence? I've been reading the MXF Book, but I'm not an experienced programmer and my reading so far seems to suggest that the MXF would, effectively, have to be recreated involving more skill than I currently have.

Any advice greatly appreciated.

Thanks,
phil

You can modify just the metadata.

If the header has some spare space (in a KLVFill item after the header metadata) you can just update the header. Otherwise you would need to write a modified copy of the file, however the rest of the file could be copied pretty much byte-for-byte - the only changes would need to be in the ThisPartition and FooterPartition properties of any partition packs in the body and footer.
