I love VD's gif animator's image quality!

My first gif using VD:

I used to use EasyGifAnimator (which costs $20), but the image quality was poor comparatively. VD's gif quality is near-perfect!

However, as far as I can tell, you can't thin out the number of frames, so it produces large gif sizes and, therefore, limits the size (height/width) and time lengths of your gifs.

I use ImageShack to upload my animated gifs, but ImageShack only allows files up to 1.5 MB.

---------------------
How I Made My Gifs With EasyGifAnimator

1. I used VD's image exporter to create the JPEGs from the video clip.
2. Usually in EGA, the max number of frames I could use for the average size I made before my computer would run out of memory was about 55-60 frames. To reduce the number of frames, I would have to open and re-size the image folder vertically to where the frames show in two columns, then I'd select one column and deleted the frames to cut number of frames in half. Sometimes I'd have to repeat this laborious process a couple of times if I wanted to make a longer gif.
3. Then I imported the thinned out collections of JPEG frames into EGA to produce the gif animation.

-----------------------
SUGGESTION FOR VirtualDub's GIF ANIMATOR

Add a method to thin out the selected frames to produce smaller size/longer gifs.

Something like a "1:2" option to cut every other frame out to reduce the number in half. If that is doable, then I'd suggest adding an array of "thinning" options (1:2, 1:3, 1:4, 2:3, 3:4, etc).

That would be sweet!

If you can do this in VD already, that would be sweeter!!!

If you want quality, you'd better export to PNG and not JPEG.

Also, check Video-> Frame Rate.
See "decimate by 2", "decimate by 3"?

Yes, if you want to use less frames, simply use the decimation option of the frame rate dialog.
