Hummingbird At The Feeder - GMIC'd Animation

GnuTux · **Posted:** Sun Aug 29, 2010 6:22 pm **(#1)**

I was playing around with my old webcam and captured some humming birds at the feeder. The cam is 10 years old and the quality isn't that good so I thought I'd run it through the GMIC paint filter to see what it looked like.

Turned out kinda cool. It's big tho & takes a few seconds to load up. :mrgreen:

(animated GIF)

Using lineart, drawing and/or other effects, some cool animations can be created with a webcam, digicam or just from a video clip found on the net.

I figure I can get a better clip, with a little more patience.

I think I might have Adult Attention Defici ooooh shiny...................

Here's another short clip using an animated png, which is smoother.

It takes a few seconds to load all the frames..

(animated PNG)

I recorded the .avi file, extracted the .avi to frames using Gimp GAP, loaded the frames as layers, then applied the GMIC filter to each layer. It's around 4 frames per second and still resulted in a 13meg APNG.

It could also be converted an AVI, MPEG or whatever, depending on what you wanted to do with it. I notice a lot of TV commercials that seem to use a similar effect as this.

That is totally awesome. Great animation, GnuTux! :coolthup

Thanks y'all.

I'm having fun playing with this idea.

Here's a 9 second clip converted to MPEG-4. Came in at a reasonable 1.2 meg file size.

I need a better webcam. I noticed much faster, higher resolution cams on eBay for less than $10. Might have to grab one.

After applying the filter to the layers, I exported them as compressed JPGs and then compressed further going to MPEG-4. Higher quality can be had by exporting layers as PNGs and using a less lossy video format, quality on par with the animated PNG example.

Maybe I should do a tutorial on this one?

Oh, yes, by all means. :yesnod

That's so surreal and so utterly lifelike at the same time.

Is there no end to the possibilities of Gimp? heheh =)
Nice animations GnuTux!

For some reason the other page loads but then doesn't play. =\

I had to wait quite awhile for the animation to play after loading. Lots of frames to activate there. The second one is an animated png image and very large. IE doesn't play animated pngs. Firefox and Opera do.

cool idea and result is good
You did wrote some script, gmic may be called and used by script fu ,may be quicker then repeat same operation over and over
....oh well thinking better also the command line of gmic version should be handy

my computer is using safari right now and I cannot see the second animation, nor can I seem to get quick time to play. I have had problems with quicktime ever since I upgraded my itunes for my phone. grrrr. Do I need a special program on my computer to see apng ?

Animated PNG files are viewable on Opera, which is free.

Yes, good suggestion. I was mulling the same idea over in my head when I was playing with this.

Yep, PhotoMaster is right. I don't think Safari does Animated PNGs.

I'll bet you don't have the exact codec needed to play back that video. I'll add another video using a more common codec and you can let me know if it works. If I'm going to post a few vid clips here and there, I'd like to use a codec most everyone can view. Thanks!!

the gmic developer wrote a example of script fu using gmic
i could not found it now, but i may search

Very good new to use gmic with webcams...well at the moment is a option only for the command line gmic anyay...

Hi. Good news, I've integrated the support of webcams in this upcoming 1.4.0.0 release of G'MIC. It concerns the users of the command-line version only.
Now, you are able to grab frames from one or several cameras as new input images in the G'MIC pipeline, with command '-camera'. As G'MIC is also able to manage display windows, it means you have a lot of new possibilities to play with filter effects in (almost) real-time (depending on the filter complexity).

The webcam support is based on the use of the OpenCV library, and is an optional module that can be selected when compiling the G'MIC framework. I'll try to write some new fun functions that use this feature soon

Great news! That will be a very cool feature. :gimp

Thanks for the links PhotoComix. :bigthup

I'm side tracked on another project at the moment but those command line options look interesting.
