It depends. There are several factors that decide how much time it will take to deliver you the high quality videos. It takes time to produce a good quality video and we are not one who can compromise on quality or cut corners just to speed up the process. On average, it takes around 6-10 weeks times in creating a high quality video, which does not include the time required to receive your feedback and do revisions. It may take an additional 3-4 weeks to do revisions and deliver the desired videos, depending on the complexity and quantity of your requests, also, your feedback turnaround time. The rest depends on how quickly you provide feedback, how complex the changes are and how many revisions are requested.
For us, every client is precious and so as their projects to us. Hence, the complexity of the project will impact the time needed to craft an animated video.
