-iv--u-15--lals-01-2-l-ve School Jr 14 .avi 2021 🎁 Official

In 2005‑2010, many schools used or Promethean boards. These systems often saved recordings as AVI files with auto‑generated names like -IV--U-15--LALS-01-2-L-VE . The -IV could be a prefix from the recording software (e.g., “Interactive Video”). The teacher was covering Unit 15 of the LALS‑01 course, and this was the second take or second language version ( 2-L ). “VE” might refer to the school’s Visual Education department.
