Only export the part of STL metadata to TTML:

GET /item/{id}/metadata/export/ttml?interval=905207@PAL-905253@PAL,904994@PAL-905065@PAL

It is also possible to apply different offsets to the exported time intervals:

GET /item/{id}/metadata/export/ttml?interval=100@PAL-250@PAL:-25@PAL,500@PAL-1000@PAL:-250@PAL
