The traditional cheap solution is a bag of beans.

What you describe is similar to what astrophotographers call lucky imaging (or speckle imaging). The idea behind lucky imaging is to take several (hundreds, even thousands) of very short exposures and only keep the few images that appear to be the least disturbed by atmospheric distortions.
In a general sense, taking more images than needed in order to ...

If you play the video at 30 frames/s, taking one picture/second is a 30x speedup. If your boat sails at 3mph, the time lapse at one picture/second will be a simulated 90mph. How much of a road can you see driving a car at that speed?
Taking the problem by the other end, figure out your "cruise" speed when in a car, divide by the boat speed. This is your "...

Well, I answered in the comments but I'll answer here since I'm not liking any of the answers.
You do need to move the camera for a panning time lapse and you used to need a rig, motorized or not, rails or not, to do this movement. There is a new technique called hyperlapse or walklapse which accomplishes this without any extra equipment, aside from a ...

There are so many variables regarding power consumption per shot that it is probably a little hard to precisely nail down. In general, shooting raw is understood to require more power than shooting JPEG assuming all other variables are equal. Even when saving image files in a raw format, a preview or thumbnail JPEG is generated by most cameras. So some, if ...

Hugin has a tutorial on their website, which made for a good starting point.
Tools needed:
Hugin
ImageMagick
Bash shell
Create a Hugin project
Start Hugin and be sure to select Interface > Advanced (Expert will do, too). Go to the Panorama Stitcher window.
Set the Field of View (50° worked well for my smartphone camera), lens parameters and projection ...

Taking sequences of periodic images, by their very nature of being periodic, is used to show changes in the scene over time.
Time slice photographs. In particular, Dan Marker-Moore has created some truly beautiful time slice photos. From his site,
A Time Slice is an image that combines series of photos taken from one location over an about of time. Each ...

First we rename all *.JPG files based on their creation date. Sometimes cameras change the file name or just ordering them is somehow not what we want. However, renaming them by the creation date always work:
jhead -n%Y%m%d-%H%M%S *.JPG
After that we put this list in a file:
ls -1tr | grep -v files.txt > files.txt
And then use mencoder to create an ...

You can do it using Magic Lantern software for your Canon. In fact, there's a setting that will save you some shutter opens/closes.

The camera does not need to be connected to the computer. There is no real danger to the camera. Depending on how long the timelapse is, you may need to have the camera on a power supply, or use a ...

If you like programing, I found a link to a python project that will do exactly what you want. It will also interpolate between frames if you are missing a couple.

I'd suggest either plugging it into the wall, a USB port or an external USB based battery. Any of these should be able to provide more power for longer runtime.

I can't watch your videos at the moment, but if I got it correct they are timelapses of a plant growing while the environment doesn't change or changes very little. It gives the impression that the plant grows fully over a short amount of time, or the the plant and the environment move at different speed.
If my assumption is correct, BBC did this for the ...

Other options for uneven surfaces which I like a lot are these ones:
Ballpod
THE pod
RiceQ (their online shop is pretty bad, if you need international shipping I'd suggest to use amazon.de)

I don't think you'll find what you're looking for, because: bigger things are bigger than small things. Full-frame cameras are bigger than APS-C cameras Medium format cameras are bigger than full-frame cameras. APS-C cameras are bigger than 1/2.3" format cameras. Just like full-sized pickup trucks are bigger than commuter cars.
I think it likely that you've ...

Frequent shooting of the time-lapse videos will eventually wear your shutter, and there is a way to limit that "side effect" other than replacing the shutter when it finally breaks. Remember that time-lapse is meant to be presented only by means of digital displays, like computer screen or a projector, not to be printed, so you don't need the full XX MP ...

I would look into hacking a GoPro camera/camcorder to use a continuous power source. The GoPro is very well suited to harsh environments, and already comes with a housing that could be utilized. Further, it is very reasonably priced. If you are serious about low light ability, the newest Hero3 Black Edition claims 2x better low light ability then the ...

There is a GoPro timelapse contoller available from Cam-Do.
This switches the camera off between each shot, which can give much longer battery life. So it can take hundreds of photos, spread over days or weeks.
This controller is compatible with the HD Hero, Hero 2, and Hero 3 White and Hero 3 Black, but it is not compatible with the Hero 3 Silver.

If you don't want your equipment stolen, yes, you (and/or a friend) stay there for however long it takes.
Very long term shots usually make use of some kind of secure box, bolted or chained in place. Depending on the location this can require permission from the relevant authorities.

Several things could be going on. Based on the question as originally written you might have been experiencing buffer congestion. When the buffer is full the camera must wait until enough space has been sufficiently cleared from the buffer as the data is written to the memory card before it can take the next frame. Under such conditions, the "double tap" ...

This kind of fast then slow performance (as you correctly guessed) will be because of the image buffer filling up. Using a faster card will help until you reach the limit of the camera's circuitry - you may have reached this limit.
Even if your camera's performance is faster than the SD card. It's quite possible that some of the card's 'bandwidth' is taken ...

Many time lapse cameras already do this, but on a shorter time scale. For example, GoPro mentions in TimeWarp documentation:
For the best results, try speeds 10x and up when shooting footage that may get bumpy. Higher speed will often provide better stabilization as there are more frames for TimeWarp to choose from
Which sounds like it is selecting the ...

For Windows, you can use VirtualDub. It is free and open source.
To create a timelapse, you need all of your photos numbered in order, without any gaps in the sequence. Then just go to File > Open, and pick the first image. VirtualDub will then load all of the images.
To set the frame rate, go to Video menu > Frame rate. You can also add filters if you ...

I use ffmpeg for this task. It is a command line program that works well on Windows.
A typical command line would look similar to
ffmpeg -r 15 -start_number 1234 -i DSC_%d.jpg -s 1280x852 -vcodec libx264 output.mp4
This assumes that your files are named according to the pattern DSC_1234.jpg and that the first file is no. 1234. The framerate is set to ...

You can use the software "EOS Utility" that comes with the camera. The remote shooting function lets you do time lapse through a connected USB cable.
Advantage:
You have the space of the PC hard disk instead of the flashcard, which is most likely much larger. That is great if you take really long time lapses.
You can also see better what is happening and ...

So I've decided to do the following:
I'm going to buy a used Nikon D40 kit with the 18-55 lens off of eBay for about $200.
To power it I'm going to use a $9 Nikon EP-5 power supply connector and a 18W 12v to 9v buck converter I found for $4.
For communications, I'm going to try a $7 10m USB 2.0 Active Extension / Repeater Cable.
I'm going to modify a PVC ...

I have no idea what algorithms commercial software uses for this task, but I'll happily make one up for you:
Find the luminance of frame 0 by summing pixel values.
For each frame (i): subtract frame (i+1) from frame (i), take the mean of these delta values. To account for movement, remove any pixels with delta greater than some threshold (set based on the ...

I would recommend taking a look at the Nikon D800 manual which can be found online here.
Page 207 of the manual describes the features of the D800 and time lapse photography.
You also will want to pay particular notice to the tips of the bottom of page 209 where it describes what modes time-lapse does not work in.
If you have a question beyond something ...

First you need to have an estimation of how long does it take for a flower to die. You can Observe a similar flower or just guess. It really depends on the type of flower and the environment (in/out soil, outdoor/indoor, humid/dry, etc). Once you have this time (let's call it Tf), then you have to decide how long your movie clip should last (Tm).
Once you ...

If you're asking how to take the images for a timelapse, what you're looking for is an intervalometer. And yes, there are several ways of achieving this, aside from a smartphone/tablet and the Canon EOS app. There are several smartphone apps that can do this. There are hardware intervalometers built into cable shutter releases. There are dedicated (mostly ...
