Title: Timelapse video
Post by: melastmohican on June 19, 2009, 14:02

My technique is very primitive. I shoot photos every 5 minutes then use PhotoLapse application to convert JPGs into movie. So far these videos has been accepted on Fotolia, ClipDealer and Pond5 but for some reason format must not fit Shutterstock. I got movies disappearing from pending queue. They are not rejected neither approved.

What codec/container are you using?

I use MOV as a container for h.264

I guess you figured already that it should work with Shutterstock.

I also assume you contacted SS support about that issue.

I only upload Photo-JPEG and Motion-JPEG so I can't give you any advice.

I got MPEG Streamclip which can convert video to MOV with Photo-JPG and voila, 3 video previously marked as corrupted were accepted.

I guess 5Dmk2 video format should be converted too cause it is using h264/PCM.

What's the difference between Photo-JPG and Motion-JPG?

I'm not a video nerd, so you won't get the full truth to that but as far as I know it is recommended to use Photo-JPEG compression for full frame (Progressive scan) video which usually comes from 3D render programs or time lapse videos since they are based on fully rendered single frames.

Motion-JPEG should be used to for interlaced video frames where you have every 2nd horizontal line switching from frame to frame (this stuff usually comes from video cameras). It kind of reduces file size and creates smoother movements but you never actually have a proper full frame shot.

Check out http://en.wikipedia.org/wiki/Progressive_scan (http://en.wikipedia.org/wiki/Progressive_scan) just for the basics.

The real technical explanation what each compression format does - I don't know.
