How can you take a moving gif file and convert to a moving jpeg file? I should say I do have a program that does the conversion but then the image is no longer in motion just static.



Thanks for your time!

Hi sweetdaughter99,

Animated jpg files are false, as they are renamed gif files. Jpg files can't be animated, but the common internet browsers recognize the type of extention and are able to execute it properly.

See: http://forums.adobe.com/thread/636367
And: http://stackoverflow.com/questions/3570789/how-do-you-make-an-animated-jpg


So to make a fake animated jpg file all you do is rename the extension for the gif file.

myanimation.gif would become myanimation.jpg :wink:

Thanks I have read some other discussions about this and tried it but after converting/renaming it is still static. (loses it's motion)

Not exactly sure what you mean. Both types of files saved to my hard drive-viewed with windows photo viewer and with paint.

jpg files are not meant to be gif files. However, the way some browsers read files, not using the extension as a guide, jpg files can be ran as gif files. So an animated gif file renamed .jpg would be ran as a gif file.

Why do you need an animated jpg file? :huh:

I don't have to have it. I am an active member of a different type of forum. It only allows for jpeg avatars but there are members that have moving avatars so I know it is possible. I will just have to ask one of them.

Thanks for all your time and suggestions. :thumbup2:

Plain and simple...no such thing as animated .jpg file.

To make a .gif file...you need several static files, be they .jpg or some other graphics file. The animation comes from the fact that the viewer is seeing a series of static files at varying speeds...giving the appearance of movement.

There are filters for various graphics programs...that can alter a still image to appear to have varying motion effects...the image then becomes (by definition) an animated .gif file.

If you take an animated .gif file and try to handle it in a program for processing still graphics...it will only act upon the first still graphic in the series of graphics that present the animation effect.

Thanks Louis-I thought as much. The forum I am speaking of has multiple webmasters which makes sense that they would know how to make their jpegs APPEAR as if the they are gif files. It is a bit beyond my abilities, but appreciate that you have taken the time to make this clear.

Just re-name the animated gif with a jpg extension instead. ie Re-name Moving.gif as Moving.jpg
