thank you very much for starting the survey. You have to assign each line exactly one column. You can not assign more than one line to a column. This means you must order the lines from most important to least important. I know this is quite difficult because all of the things are very important but depending on your job in post pro you might come to a different conclusion than someone else.
I hope this answers your question?! If not let me know.
I would appreciate it very much if you would give it a second try.. i have some trouble finding participants for the survey..
