When I am saving 30/40 sec video as a gif format, its color is changing. I save a 40-sec pure white video as a gif but after saving it the gif is being yellowish. How to solve it?

Short answer is not to use GIF. It is limited to 256 colors, so the thousands that are in your video, even if it appears white, are shifting it towards yellow when they are compressed.

A pure white GIF with few colors should render white.

Heres a second example. First a still image from the video.
Then the GIF directly below.



I'm using Camtasia for Windows.

Pure white 255  255  255.  Is one of the colors GIF uses. I'm not sure why your seeing a color shift?

I'm curious what your trying to render?

Background is almost pure white. R 254 G 254 B 252.
Heres a color picker screen shot.My colors don't match yours.



I use a color calibrated monitor.So my colors display generally dead accurate.

I downloaded your GIF and applied the color picker to all your colors and the background in this image.You'll see RGB values in the properties panel.The color picker and it's corresponding number can be found on the image.

I assumed you were referring to an easily detected yellow color shift.

To me, the difference between RGB 254 254 252 and 255 255 255 is so minor, I can't see the difference with my bare eyes. Unless compared placed side by side.
Even then, I have to look closely to detect the difference. I created the image below in Photoshop.



I get readings of 254 254 252 with Camtasia GIF renders as well.I've never tested my GIF's for pure whiteness with a color picker before. After drilling down deeper into this, I now see where you're coming from.Sorry I misunderstood you.}:>(

I contacted support. They are unaware of any color shift issues. They stated they would look into it. And see what they can find out.

So now it's a waiting game.I'll let you know what the response is.

So, Shakibul Islam

I've received my reply form Tech Support.

Further investigation indicated possible issue with the .GIF format in general

Issue has been passed top developers before, unsure of any timescale or possibility of fix.


Regards,Joe
