Hello,
I have over 16 years of video editing and development, this is actually a piece of cake to myself, I'd also do this within the 24 hours, it is basically based on the size of the video and it's quality which by turn affects the size of the file and the time spent on rendering the final one.
I have one little question here. What type of content does this video have?
The link to a sample, which shows the green screen used in producing the video, then it is replaced by a moving background.
[link will be added later]
Please communicate with me in PM.
Best regards,
P.S.: This is my second bid on your projects today.
