HELP COMMENT

A quick sum of what I have done so FAR..

jonnykeogh — Fri, 13 Nov 2009 12:38:26 +0000

I have done a few experiments in time lapse and have achieved very different things, the time lapse it self is far to Documentary like so does not answer the brief properly so, I am now currently drawing up a story board to edit my hour long video in to an experience other than a documentary. My original goals to make something like the research are not suitable, finishing with a very nice clean time lapse. In my hurry to produce a time lapse because I have wanted to for a while, I kinda forgot about the story, Sooooooo im now using the footage I have got and picking out the best bits to try and create a video/ animatic that is more interesting.

Some experiments in frame rate/time lapse

jonnykeogh — Tue, 10 Nov 2009 10:48:12 +0000

I though I would experiment in different ways before I try to film the desired outcome so… I have done some simple experiments using ISTOPMOTION.

this is just me working, with the compter taking photos of me.

This next one is a time lapse I made with ISTOPMOTION.

The original time lapse was 17 minutes long so i shrunk it down and the sped it up

Post spectacular link, AIRSIDE,

WHOOP WHOOP

HELLS YEAH

HD??????

Im thinking because my time lapse, i want it to be bright and vibrant i might try to do it in High definition to get the best result.

Here is some HD research on time lapses

I feel filming in HD is just really nice it makes things thast little more crisp.

Again the colours are really vibrant.

Just amazing camara work and landscapes

Ummmmm WOW

This time lapse is alot of fun and is quite incredable when we see hot air balloons has slow moving gentle things.

VIDEO?

Technique number one is to use the camera itself to do the time lapse recording for you. Almost all digital video cameras have the ability to do an interval recording. What this means in a nutshell is that you tell the camera how long you want to record for and how long in between recordings and it will go on autopilot for you for as long as the battery lasts or the tape runs out. This is what those cameras at the convenience store do, they record a few seconds of motion every 30-60 seconds giving the overall view of the traffic in the store over time.

How to time lapse sort of?

How time-lapse works

Film is often projected at 24 frame/s, meaning that 24 images appear on the screen every second. Under normal circumstances a film camera will record images at 24 frame/s. Since the projection speed and the recording speed are the same, the images onscreen appear to move normally.

Even if the film camera is set to record at a slower speed, it will still be projected at 24 frame/s. Thus the image on screen will appear to move faster.

The change in speed of the onscreen image can be calculated by dividing the projection speed by the camera speed.

So a film that is recorded at 12 frames per second will appear to move twice as fast. Shooting at camera speeds between 8 and 22 frames usually falls into the undercranked fast motion category, with images shot at slower speeds more closely falling into the realm of time-lapse, although these distinctions of terminology have not been entirely established in all movie production circles.

The same principles apply to video and other digital photography techniques, however until very recently video cameras have not been capable of recording at variable frame rates.

Time-lapse can be achieved with some normal movie cameras by simply clicking individually frames manually. But greater accuracy in time-increments and consistency in the exposure rates of successive frames are better achieved though a device that connects to the camera’s shutter system (camera design permitting) called an intervalometer. The intervalometer regulates the motion of the camera according to a specific interval of time between frames. Some intervolometers can also be connected to motion control systems that move the camera on any number of axes as the time-lapse photography is achieved, creating tilts, pans, tracks, and trucking shots as the speeded up motion is viewed. Ron Fricke is the primary developer of such systems, which can be seen in his short film Chronos (1992) and his feature film Baraka (1992, released to video in 2001).

[edit] Short Exposure vs. Long Exposure Time-lapse

Exposure time in frame interval

As first mentioned above, in addition to modifying the speed of the camera, it is also important to consider the relationship between the frame interval and the exposure time. This relationship essentially controls the amount of motion blur present in each frame and it is, in principle, exactly the same as adjusting the shutter angle on a movie camera. This is also known as “Dragging the shutter.”

A film camera normally records film at twenty four frames per second. During each 24th of a second the film is actually exposed to light for roughly half the time. The rest of the time it is hidden behind the shutter. Thus exposure time for motion picture film is normally calculated to be one 48th of a second (1/48 second, often rounded to 1/50 second). Adjusting the shutter angle on a film camera (if its design allows) can add or reduce the amount of motion blur by changing the amount of time that the film frame is actually exposed to light.

Blurring vs. exposure times

In time-lapse photography the camera records images at a specific slow interval such as one frame every thirty seconds (1/30 frame/s). The shutter will be open for some portion of that time. In short exposure time-lapse the film is exposed to light for a normal exposure time over an abnormal frame interval. So for example the camera will be set up to expose a frame for 1/50th of a second every 30 seconds. Such a setup will create the effect of an extremely tight shutter angle giving the resulting film a stop-animation or clay-mation quality.

In long exposure time-lapse the exposure time will approximate the effects of a normal shutter angle. Normally this means that the exposure time should be half of the frame interval. Thus a 30 second frame interval should be accompanied by a 15 second exposure time to simulate a normal shutter. The resulting film will appear smooth.

The exposure time can be calculated based on the desired shutter angle effect and the frame interval with the equation:

Long exposure time-lapse is less common because it is often difficult to properly expose film at such a long period, especially in daylight situations. A film frame that is exposed for 15 seconds will receive 750 times more light than its 1/50th of a second counterpart. (Thus it will be more than 9 stops over normal exposure.) A scientific grade neutral density filter can be used to alleviate this problem.

This is really a really helpful site on how to make a time lapse.

Some more time lapse reseach

I like the fact this depicts the change of the stadium into another thing.

It looks like the dam is growing out the grown like a flower

This time lapse uses in the first 1minute a really nice effect as where it is rotated 270 degrees to make a nice effect and a almost panoramic view

Some really nice time lapses that have a feel almost that there not real and could be made of dolls and figures.

they almost look like micro machines or remote controlled cars

This is my favorite just because of the bright colours and the excitement it captures.
