The point of “Unlimited” is to not limit what you can do in a month. However, somethings are also not humanly possible such as altering space-time. The 1-2 day turnaround is because of physical limitations of the video medium. Computers still take time to render video. Internet still takes time to upload and download. Time still passes linearly.
So, if you have 30 hours worth of raw, unedited footage for me to go through, you can expect at least 30 hours of me sitting in front of a computer going over your footage – especially if that video includes dialogue.
There is also the limits of legality. I will try very hard to find any song you want to use in your video, but Copyright Laws do protect artists and corporations. So, it may be possible that the version of a popular song you want in your YouTube Ad might not be available. I can, however, track down legal “sound-alike” songs or artists, as well as media.
And finally, the limit of video itself. If the video didn’t get it, there’s a chance that no amount of editing will get it. Badly recored audio? Noisy space? Bad lighting? Send me the footage and we’ll see what we can do to the best of what’s humanly possible.
