Post Best Frame Rate - 23.976 or 29.976 or 24 or 30?
I have been doing time-lapses for online purposes and showcasing for over 3 years now. I come from a world where all our videos are 23.976 but im wondering what the best results are with Time-lapses. I heard that to get a much smoother playback you should process them 29.976 rather than 23.976. Im also confused on the 24p vs 23.976, why are we still using this crazy number (23.976) and not just 24. Isint that for broadcast, like 29.976, and not online video.

What are your thoughts for 1. Stock Selling purposes and 2. for a Cool time-lapse showcase video of deserts and nature stuff?

Thanks,

the beauty of time lapse is that it doesn't have to sync to any audio and it is manipulation of time so changing frame rates isn't as big a deal as real-time video - you can render out multiple frame rates to suit your client's needs - you can have a 23.976 fps version and a 29.97 FPS version along with any other fps version you'd like - the reason people go with different frame rates are many and varied. TV in america is running at 29.97 FPS it has to do with adding a color subcarrier to make it backward compatible with B&W TVs. There are plenty of resources out there to figure out the whys of the different FPSs. I typically create a 29.97 HD version, because that is what is typically called for in stock footage - however like I said since it is time lapse you can reinterpet the footage in a program like AE to whatever FPS you are using.

Don't forget about 25fps too ;)

I'm in the same camp as pixelbot in that I render depending on the needs of the project that the footage is for. If its for a stock library find out what they prefer. If you must pick one then I'd suggest 24fps is the best overall compromise that can be slotted into all the other frame rates without too much trouble. If a frame for frame conversion is done then the only thing that changes is the duration of the shot.

I guess I was looking for a Opinion on what is the best looking frame rate for smooth Time-lapses. I used to do everything in 24p but had some smoothing problems, the pic looked jittery. I switched a couple to 29.97 and it looks smooth. The question now is im making 3 products with these timelapses, a Mini TL featurette about 3 minutes, I think Ill render them all out 29 and have the small feature be 29. it just looks too good. But the other is a series of videos about each place, or episodes, that were already shot in 24p video. For the eipsodes should I just toss in the 29 in Premiere at a 24p timeline and will it auto change it with out any issue. and the 3rd is Stock Footage. I used to just upload 24p but Im thinking that 29.97 is better.

If the 29.97 is working for you then stick with it. However you may want to look into why your shots look steppy at 24fps. Your intervals may be too long or you might need to use a slower shutter to add more motion blur. When I first started shooting with a slider and an Emotiomo TB3 I found that I was getting very steppy motion. Fixed this by slowing down the shutter (ND on the lens) and using more intervals in the moves.

Yea we fixed that stepping problem doing just what you said. We're processing the older ones now and trying to fix the problem. Dustin Farell said he always shoots his processes his time-lapses at 29.97 on his lynda video. I hate switching to something other than 24p but I gotta try it. I wonder what Timescapes was. I bet he just shot everything smooth from the get go and its 24p with no problems.

I'll generally stick with 24p.
You can add motion blur with after effects to smooth sharp images out if you have to.
Converting actual 24p to 30p and vice-versa looks horrible 95% of the time, even with proper image interpolation time-lapse does not always behave as well as normal footage. I avoid it.
24p to 30i can look OK. Generally best to stick with the 1:1 photo to frame rate though.

This is a very deep subject, that even after reading much about I still am at a bit of a loss as to the best way to go. I have been rendering all my time lapse out into 23.976 FPS, shooting dslr video at 30fps (to slow down to 80% in a 23.976 timeline if I want a more buttery video feel). But this lengthy discussion over at reduser.net is swaying me to want to go straight to 24fps with my time lapse renders: http://www.reduser.net/forum/showthread.php?108798-24-FPS&highlight=24fps+23.97 (the article gets deep a page in or so)

Hope that helps.
