Which tags to save Original Filename for Video files

[aperturemode]

Wondering what is best practice for storing the original filename of a video file before renaming the file.

Is it best to use XMP:PreservedFileName for example, or would a tag such as Quicktime:Keys:Title make sense? A post from Stargeek on May 10, 2019 suggests this below (not sure if it is intended only for photo files):

Myself, I write all three of these tags as the first step after downloading images from my camera
exiftool -P -overwrite_original "-XMP:PreservedFileName<Filename" "-XMP:Title<Filename" "-IPTC:ObjectName<Filename"

I'm using Lightroom Classic for organization (not the best for video but it seems convenient since I'm using Lightroom for photos).

Thanks.

For a video, I would just use XMP:PreservedFileName.  I believe that Title in a video file is more like Headline in an image file.

In image files, Title is

A shorthand reference for the digital image. Title provides a short human readable name which can be a text and/or numeric reference. It is not the same as Headline.

IPTC Photo Metadata entry

I think that Quicktime have a variety of tags that can be used for this.

Simple is best, I will just use your XMP:PreservedFileName suggestion. Thank you, StarGeek!
