Hi, I would be glad to do this animation for you. My bid includes the following:
1. 3D modeling of the lock accordingly to your instruction (please note I would need drawings of the internal components and an actual assembly diagram, to make it realistic)
2. Photorealistic 3D animation similar to the youtube link provided, but better quality (including exploded model assembling into a lock etc.)
3. Video editing, subtitles (if needed), soundtrack application. Please note this offer does not include copywriting and soundtrack creation, you'll need to provide me with narration, logo/screen art, and/or music/soundtrack, which I'll align to the animation.
I'll provide you with 3D model as well, so later it'll be cheap and easy to apply any changes, and to update your animation (for example for a new model of your lock). Thanks!
