I just directed the film. I didn't know what was going on during the editing ... I agree with the flickering but I didn't have a say in that or the soundtrack.
If you didn't even know what was going on during editing, let alone actually "direct" the editing, then by definition you did not direct the film! From what you have described, it seems like your film didn't actually have a Director.
The visual style (B&W, flickering) implies early film and the music implies more precisely the 1920's and yet we see computer keyboards, contemporary electrics, whiteboards, etc. There is no storytelling rationale for this contradiction and that's why the storytelling doesn't work.
... so what I learned from that moment was that I have to get my position and power noted as Director and to go with what I think is right. The main thing is too mostly plan, that is necessary.
I think what this film proves it how vitally important it is to have someone with a vision of what the end product is going to be and for that someone to follow that vision through the entire filmmaking process. That "someone" is of course the Director and is why films always have a Director. In other words, it's not just a case of getting your "position and power noted" by the rest of your filmmaking group, it's a case of everyone understanding what the role of Director actually is.
As you have learnt, planning is vital however, a plan is defined as "
a detailed proposal for doing or achieving something". So before you can start planning you actually have to know what you are planning for, what it is you want to achieve, and this brings us back to the role of the Director and of creating a vision for the end product.
