THE PROBLEM
I've created an HTML animation using google web designer, then I need to export my project as a GIF. Google web designer doesn't provide any tool to export as GIF so:
WHAT I'VE TRIED
I've tried to record my screen (using quick time player for MAC) crop and cut the result and then convert the MP4/MOV file to the GIF.
CONCLUSION
I'm not very satisfied with the result, the resulting GIF is very big (HTML is like 20KB and the GIF is 500+KB ) and the quality is mediocre.
Can someone provide me with a better solution or something to improve the quality of the result?

I want to add a button to my flash game (AS3) and on click it saves a picture of the current users whole screen and saves it to pictures/disk automatically, but I don't know how to do that, I know how to add the button to the UI and add a click event and all that, just need to know how to make it save a picture of the current screen to disk (doesn't have to be just the flash screen, can be the WHOLE screen of the users pc, either way works!)
I was on my way writing you the answer but I found this post have a better explaination: Is it possible to capture the screen and save the image in actionscript 3?
"Yes, it's possible.
Draw some display object to a BitmapData (the stage, for example) and crop it if neccesary (the second param of BitmapData::draw will help you out here).
Then, convert the raw pixel data to JPEG or PNG using some encoder. I'm sure up to this point, this is what those tutorials will explain you how to do.
Now, the third step is different but simple enough. Instead of sending the image data to a server side script, use a FileReference object. Since Flash Player 10, it has a method called save, that prompts the user to save a file locally.
Since this is a desktop app, you could also make it an AIR app. This will give more direct access to the file system and other features, in case you need them."
I've noticed that on some sites, a very low resolution version of an image gets displayed underneath the final version before it's done loading, to give the impression that the page is loading faster. How is this done?
This is called progressive JPEG. When you save a picture using a tool like Photoshop you need to specify you want to use this JPEG flavor.
I've found this Photoshop "Save for Web" dialog sample where you will find the whole Progressive option enabled:
What you are asking for depends upon the decoder and display software used. As noted, it occurs in progressive JPEG images. In that type of JPEG, the coefficients are broken down into separate scans.
The decode then needs to update the image in between decoding scans rather than just at the end of the image.
There was more need for this in the days of dial up modems. Unless the image is really large, it is usually faster just to wait and display the whole image.
If you are programming, the display software you use may have an option to update after scans.
Most libraries now use a model where you decode an image file stream into a generic image buffer. Then you display the image buffer. In this model, there generally is no place to display the images on the fly.
In short, you enable this by creating progressive JPEG images. Whether the image displays fading in dependents entire on what is used to display the image.
As an alternative, you can batch optimize all your images using the ImageMagick's convert command like this:
convert -strip -interlace plane input.jpg output.jpg
You can use these other options instead of plane.
Or just prefix the output's filename with PJPEG
convert -strip input.jpg PJPEG:output.jpg
Along with a proper file search or filename expansion (e.g.):
for i in images/*; do
# Your conversion command
done
The strip option is for stripping any profiles or comments, to make the conversion "cleaner". You may also want to set the -quality option to reduce the quality loss.
It's posible convert an image sequence (jpg, png) to .flv (or .mp4 instead), using AS3/AIR?
I'm developing an app. This app must record video on an Android tablet.
As the "CameraUI" class doesn't permit to put images/design over the camera capture, and I need to overlay branded design,
I'm trying to save a sequence of bitmaps using this Starling extension (Using this extension I can overlay desing and it's manage a good performance).
My idea is take the generated image sequence, convert it to video, and then to delete the original bitmap files.
Any idea?
Thanks.
Yes this is possible. FLV is an open format. Easiest way is to create raw flv. Otherwise you need to search for the proper compression (there are libraries online).
For the first one, there are a few very old posts, but I think the idea is the same. Few can be found here:
http://www.zeropointnine.com/blog/simpleflvwriteras-as3-class-to-create-flvs/
http://www.joristimmerman.be/wordpress/2008/12/18/flvrecorder-record-to-flv-using-air/
Try to search for 'flv recorder'. There are few out, even with compression and audio.
So, I'm trying to make my flash "games" run more smoothly. I am using individual PNG files for each of my objects in order to create player animations.
I've heard from some places that using individual files like that is bad.
I heard about using sprite sheets in order to compress data and reduce memory usage.
Maybe I have it wrong, but is there a way to merge all of my PNG images (with transparency) together in such a way that flash can continue to use the images individually?
I am really looking for ways to make my programs run more smoothly in order to be able to have lots of images on screen without much lag. Any ideas on how I can make things run better?
Here is an example of a tile based game I'm trying to make that is having serious lag issues.
TexturePacker allows merge png files. It generates two files: png and config file. Png is just merged images and config file is txt file which you can load into your swf, parse and demerge your images using it. Config could be in various formats for different game engines.
Using Photoshop or similar software you would combine all of the animations frames into one file. The size and shape of the file can be whatever you want, but each of the 'frames' should be the same size, in the same order and with no space between them. For example, lets say each frame is 25x25px, your walk animation is 10 frames and you want the final .png to be one long strip. You would make a new .png with the dimensions of either 250X25 or 25X250 and then insert all of your frames into that one file in the order of the animation. It's up to you if you want to embed these as display object or files that get loaded, but once you have them you just need to use BitmapData to break up the input file into new BitmapData objects and then display them as needed. Going one step further, lets say that most if not all characters have a walk animation and an action animation, you would make a single class to deal with loading character animations and the first row of the image file would be the walk animation and the second would be the action animation.
I am creating a flash site where someone can customize a canvas. Then they can preview this canvas on the product. Because of the way monitors display colors, we wanted to try to embed an icc color profile in the previewed image so the user can get a better idea of what the end product will look like. For instance, if they upload something with a really bright red, the preview will show this in a more realistic color to what can be printed on the canvas. This preview is generated on the fly in a flex application using as3.
How I could go about doing this? Is this possible? I realize I could fake something by manipulating colors in flash, but the printer that prints the canvas is able to export an icc profile that will be more accurate. So, I'd like to use that if possible.
