Time lapse

| ->> I'm setting up a remote camera later this week to do a time lapse for an event and the event will be about 12 hours. I'm working out how often to shoot a frame and was wondering if anyone has found a good ratio that you like. For a shorter time period I would probably do a shot every min but since it will be nearly 12 hours I'm thinking of every 2-3 min or even 5 min. I just don't want to leave to much time in between shots. I know this is all a matter of personal preference so I will probably pick a number and go. I'm asking more to find out if others have a number that they like to do when doing time lapse. |

->> What you are asking is very hard to impossible to answer without knowing what your subject is, what the final product is to be, etc. For example, doing a timelapse of weather is a lot different than erecting a building.
And how are you going to process the imagery? Are you going to let the camera turn the stills into a video automatically or are you going to do it yourself in post?
If you're doing it with the most control -- manually versus the camera doing it for you -- then simply shoot every minute and if that turns out too slow, then go back to your imagery, choose every fifth frame and reprocess which will then give you a five-minute transition.
It is always better to have more and pick what you need afterwards versus setting the camera at five-minute intervals and wishing you had chosen one- or two-minute periods in post. Having one-minute frames gives you a lot of images that you can cull down later for a different speed effects.
Think of it like shooting sRGB versus RGB. You can always downsize the color space of RGB to sRGB, but you can't go the other way. |

->> Thanks for the feedback. I'm setting a remote to take a time lapse of a wrestling tournament from an over head position. I plan on just having the camera take the photos and I will process them down later into a video.
I had been leaning towards what you mentioned and shoot more then pull some images out if it is to long. |

->> I put together a very basic excel spreadsheet you can use if you want me to email it to you. You'll just need to enter the duration of the thing you're shooting, your desired FPS, and the length of the video you're wanting it to be. It'll tell you how many minutes between each shot you need. (You can also calculate it yourself this way pretty easily, but I just saved it in excel to avoid having to think about it on the rare occasions I do it.)
I'm sure there are apps that do the same thing with a pretty interface. |

->> David,
Hopefully you have an ac adapter to power the camera for the entire 12 hour shoot. |

| ->> Probably more limited by the number of shots vs the shoot duration. A one-minute video will only need about 1500 shots at 24fps. (Be sure to have enough card space, btw.) |

->> Ben - I have multiple AC adapters for remotes.
And I have several large CF cards that will be able to hold the needed photos.
I have decided to go every min and then cut photos I don't need. |

| ->> A 30-second video from a 12-hour shoot will take 720 photos, and you're spot on for 60 seconds being the interval (unless you wanted certain portions to lapse at different speeds). |

->> Meaning:
1 shot per minute x 60 minutes X 12 hours = 720 frames.
720 frames / 24 fps = 30 seconds. |
