If you do not know your vendor ID, you can enter any
placeholder text here and your delivery partner add a valid
vendor ID to the package before submission to the iTunes
Store.
Important: The vendor ID can contain only alphanumeric
characters and underscore marks; it cannot contain spaces,
dashes, ampersands, other punctuation, or symbols. The
vendor identifier is case-sensitive and must not start with an
underscore. If a Vendor ID is numeric, it’s treated as a string,
not numbers (for example, a vendor identifier of
000000000123456 is not the same as 123456). Vendor IDs
must be at least six ASCII characters in length but not longer
than 100 ASCII characters.

you want to save the package.
Important: The iTunes Store requires specific video and audio
settings in your package submission. Therefore, it’s not advisable
to make changes to the Video and Audio inspectors for the
Feature or Preview items in your iTunes Store Package job.
Configure subtitles, closed captions, and
alternative audio tracks
After you add a job containing subtitle files, closed-caption files,
or alternative audio tracks, you must configure those elements to
ensure that they’re labeled with the correct language and other
settings.
