    I am a student at Long Beach (CA) City College, taking a Non-Linear Video/Film Editing course using Premiere Pro. My Professor is an expert in Video Editing and with Premiere Pro. On the Editstock J-Pops product page the Director of the J Pops video shoot, Ross Ching, notes:

    Director’s Note

    “With just enough VFX and speed-ramping to make things interesting, J-POPS is an extremely enjoyable editing project for beginners.”

    I regard that as a little confusing, if not misleading, because above the “Leave A Comment” area on this page, under the Overview, there is a difficulty rating for the “After Effects Sky Replacement With J-Pops Commercial” Tutorial, one of two Tutorials offered by Editstock that cover two separate edits of the J-Pops Re-Edit. The replacement of the sky edit is not rated “Beginner”, but rather:

    Since it is probably Editstock’s “Description” on the product’s page that the J-Pops Re-Edit is rated at Intermediate Difficulty, it must be Ross Ching’s lowball “Note” that the J-Pops project is, again:

    Director’s Note

    “… an extremely enjoyable editing project for beginners.”

    and seems a little “off”, at least. But Editstock does include the Director’s Note on its website, so that is why I am making this comment to Editstock, and including it in my thread on the course project’s Discussion for my Non-Linear Video/Film Editing class. I have to say that most in my class of 20+ students have some experience with video editing, if not video editing with Premiere Pro, but there are some who are new to video editing and are first time users of Premiere Pro. When the Director of the video footage Editstock is packaging for Video Editors and Educators, notes that :

    “J-POPS is an extremely enjoyable editing project for beginners.”, Something is a little “off.”

    Oh, and did I mention that on Editstock’s J-Pops product page, he J-Pops play button has the category/rating of the J-Pops product as:

    “Commercial / Action / Beginner / G”???

    But didn’t you need to move the background layer of the girl on top of the sky, to bring back the areas that are keyed out? I notice the label on the leftmost bucket is still keyed out in the end.
