As promised, sharing my thoughts

The main is I think the reel should be
more personalized that way when a potential client could see/hear/feel the value of the advertised product or company
TO HIM. I mean the usual
pitching approach as to move by the chain of “hook-context-CTA” REFLECTING (or natively hinting to) THE CERTAIN “client’s pain” + “advertiser’s solution”. If we look at examples of the
best Saas explainer videos we can notice that each of them defines the product or the company’s activity and explains its’ benefits.
So, once it is the ads for CAD-engineering company I’d put into the video some details
associated with the target audience (project owners, managers etc).
For example, to add the caveman’s phrase “
Uhhhhh, when I finally finish the project {i.e. client’s “headache”} ??!!”, depending on CTA at the end of video. It can be shown as a sign of thinking out loud or voiceover and/or as the sign “project” (or another client’s main problem) at the box with stones, which might be marked also as {detailed difficulties/factors} eg “budget/time/team” and so on. Preferably
to add it at the first 5 sec frames even if it’s not for YouTube placement.
There might be also some “boosting factor” added, like for example a “bird landing at the stones box” or “strong wind blow”, illustrating “unexpected clients’ pains” stopping project (caveman’s movement), but released with “R2AT’s wheel designed”. Perhaps, on 39sec frame to add sign “CAD” to the master’s drawing tablet.
Normally, the company ordering creative video should give the brief with detailed requirements, ideally with the script…. Unlessthey order both script +video. Anyway, they should have directed you from the beginning with “What audience is video for”, “what client’s problem and solutions to be enlighten”, “what client's actions (CTA) to be resulting upon watched ”. As far as I understood, you’ve not been provided with all that staff, but with context only…
I’m really impressed, how you’ve made the ads without given full details! Really well done!
