Right now the ability to change starting timecode to a clip is possible only if applied on a single clip.
But when I try to modify multiple clips the option is grayed out.
I get logging notes from directors and producers and they watch the footage on non-professional video players like VLC where the timecodes of each clip start from ZERO.
They send me editing instructions with the clip's name and the timecodes so when I start the project I go over the footage and change the clips to start at zero so the instruction's TC and footage TC will match.
It's impossible to change dozens or hundreds of clip settings one by one.
I saw this thread that suggests a way to use Console scripts.. but it's very complicated and tedious + sometimes it doesn't work.
So please add this basic feature that other NLE's already have for many years.
Here is the thread with the script solutions.
