Using CHDK, I made a timelapse of my terrarium today. This is a 55 gallon tank with 5 frogs in it. The video is just taken on one end, where it appears that 2 frogs were hanging out all day.
In this video you will see...
-A male frog spending the day trying to court a female
-Another male try and take over the territory, but get beaten back (2:00)
-Slugs and snails (slug in the lower left at 1:44)
-mites, springtails and flies on the glass
Here is a link the my vimeo account. Please watch this version, the resolution is much better than youtube.
And if you require an embedded youtube video try this, but the link above has so much more detail watching this one is a waste.
Pretty rad...and oddly I was just thinking about doing something like this with a new viv thats growing in. Maybe taking a pic every day, few days, week whatever, and editing them into an animated gif, avi or something. Could do that till the viv is pretty well grown in, would be pretty cool to see I think.
The video was taken over about 12 hours, and the frogs are on a 14 hour day cycle. I stopped the video about 1.5 hours before lights out, but they had already retreated for the night.
Nathan, if you are thinking about doing a timelapse video project, I highly recommend you check out CHDK, which allows you program a cheap point & shoot Canon camera for timelapse with whatever settings you would like.
can this be done with a regular webcam? what program was used if so?
i'd like to see if my seemingly secretive imis actually move around like that.
James, you can use a regular webcam. There are two main steps to making a timelapse...
1) Create an image sequence
2) Compile the image sequence into a video
When I do stuff like this, I like to have as much control as possible. That means there are likely much simpler ways of doing this, but here is how I would do it. This is for using a PC.
Step 1 - Create an image sequence
First you need a program with timelapse functionality. Your webcam software might have this, it's worth checking. For a FREE (as in beer), buggy program, I use AnimatorDV . Once you install it, it will ask for the serial number, which is listed below the download button on the page I just linked.
When you open the program, click "new project" and set the image size to 480x640 (it might default to something smaller). Play with the exposure and contrast and color balance until the picture looks good. Then click "Tools -> timelapse". Set the image format to jpeg, click OK.
On the right, it should now have timelapse settings, such as interval. For the video I linked, I used a 20 second interval, but you can use whatever you want. Later, you will be able to change to framerate if you want to speed it up or slow it down. Click the green start button and sit back. If you are around durign the day, you can play the video while it is still recording. Keep in mind this program is really buggy, so you might want to pay for a better program, but this one works for what I need to do.
Step 2 - Compile the image sequence into a video
Now that you have finished recording, you will have a folder full of jpegs. You need to convert them to a video file. There is an excellent free program for this, which is called "VirtualDub". Once you open virtual dub, just open the first image file in your image sequence, and it will convert your image stack to a movie. You can now watch the video on your computer, and use the slider to scroll back and forth. Before exporting the movie, two more things are required.
First, set the framerate. Click "Video -> Frame Rate" and set it as desired. 16 fps makes a nice smooth video, but if you want to add a song, you will want to adjust the framerate to make the movie the same length as the song. If you have way to many frames, you can tell virtualdub to drop frames, so that you don't have an insanely high framerate.
Second, you will want to add compression. This will reduce the size of your video by at least 10 times, which will allow you to upload to youtube or vimeo with no problems, and also wont take up a bunch of hard drive space. I use the xvid codec, but there are a number of good ones (H.264 is another good one). To add video compression, click "video -> compression".
Now click "File -> Save as Avi" and you should have a video, which you can upload to the internet. Please post a link if you make a video.
