Purpose of this document is to summarize as simply as possible the updates in video transcripts module on deprecating content-store:
...
One might also see <transcript/> tag directly under <video/> as seen in the above example. This tag previously contained contents of transcripts field, but now this is kept there for backwards compatibility on importing new OLX format in older open edX instance(<= ginkgo) since this references the old as well as new styled transcripts.
...
On importing a course, all the video transcripts are imported into S3 and their metadata is managed by edxval in VideoTranscript data model.
The above also holds true when we import an old OLX format into the edx.org or a newer open edX instance (>= hawthorne) Or even if a course OLX is a mix of old and new styled transcripts.
Note:
As of August 13, existing transcripts in the contentstore have also been migrated into the S3 for edx.org. These Import/Export of these new-style transcripts only make use of <transcripts/> tag under <video_asset/> in course OLX.
