Hi folks,
I just wanted to report my first test making a 4K video with CDHK interval script. I used my Canon PowerShot 780IS with CHDK interval set to 5 seconds to capture 128 frames at 4000x3000. IrfanView batch convert was used to rescale and crop down to 3840 x 2160. Then using FFMpeg I was able to convert the series of images into a 4K movie and succesfully upload to YouTube which recognized the format properly:

Thank you CDHK and looking forward to making some good 4K time lapse movies!
