A button corresponds to the image type you need to generate (GIF - Animated GIF, APNG - Animated PNG format). GIF format supports only absolute transparency or no transparency at all.Therefore, when you select the GIF format and set background to transparent you will still be able to set a background color that will fill the back layer of semi-transparent parts of your image. All transparent pixels will be filled with the given background.
The default best quality maximum size of each image is set when selected from the list.If you need to do so, there are many free browser add-ons available for that– do some searching to find something that works well for you.)Download and install these as necessary.For this example, I’m making a from the 1925 silent film of The Phantom of the Opera, as it’s in the public domain and I happen to have it downloaded (doesn’t everyone?! Part one: Getting the screencaps Note: The important part of this step is to amass the frames you’ll need for the animation.Avidemux is not the only option out there to accomplish this and so there are ways around this step if you need it.If you even have any video player that can take screencaps (VLC is a free program that does) you can do this manually by taking screencaps yourself– you’ll probably want one screencap for every few frames of the section of video you want to use.We’re going to need a set of screencaps from our video to form the frames of our animation, and Avidemux is very good for this. You might get messages from Avidemux about different options for dealing with your video depending on its format.
This tutorial isn’t going to cover the details of Avidemux – as a general rule, just pick one, and if that doesn’t work, open the video again and pick the opposite.
Find the place you want your animation to start (try using the arrow keys to nudge to the perfect spot). Find where you want the animation to end, and click the button. (If you don’t have this option, you probably don’t have the right version of the program– see the notes at the start of this tutorial.) Avidemux will save for you all of the frames in your selection as individual .jpgs, which could lead to a lot of images, so give your set of images a name and save them in an appropriate place.
In order for the image to have proportional width and height, check the "Constrain proportions" box and it will change the other parameter in regards to the entered one.
If you want to get back to the original size of the image, click on the "Reset sizes" link under "Preloader size" title.
Today, we are going to make an animated using all free, open source programs with no watermarks.
