Something is definitely odd about the color tables and the movie rendering. After saving a lot of burning ship zoom sequences I've just started rendering one, and it's coming out with completely different colors from the ones in the saved jpegs. I'm using the 1.21 version of the movie maker -- should I have updated that too?

@ellarien, 1.21 is the latest version. I will need to render a sequence to see if the palette doesn't work... Edit: Color offset is not read by kfmm. Also color cycling, number of colors, color division and color waves can be changed in kfmm, it may be this that differs? @laser blaster, Changing the window size only affects the render if the new size is larger than the background memory image. I haven't done that much though so I haven't tested that. If it crashes the program I didn't know, it's easy to fix though. And unfortunately I haven't render with together with storing jpeg either. I think there is a problem with that, memory leakage perhaps, I need to investigate that. Edit: Even though the jpegs comes out as black, due to this memory leak, the kfb files are usually ok and you can view them in the movie maker. I never stor jpegs anymore, and I use the kfmm program to check the result, by entering the frame number and click the test button... ratcat65 - yes you are right, I have forgot to implement that in kfmm. Will do that

Wait, there is a different way to render than to store zoom-out images? I just want to be able to resume the rendering from where I left off and then put together a zoom movie. I could manually enter the coordinates for the next frame and start a new zoom sequence, but then will I be able to combine it with the previously rendered frames to make a full zoom video?

Yes, if you enter the coordinates manually you can start a new sequence with the menu "Store zoom-out images" (instead of Resume...) The existing kfb files will be detected and the file number will be increased. But make sure you set the zoom value with many decimals (more than 4) so that there wont be any visible joints

I wasn't doing anything fancy with the colors in kfmm, but there may have been an offset. I guess that would explain it. Thanks!

I posted some images on Flickr.I'm rather intrigued by these things, south of the Western Antenna -- as far as I can tell one could zoom in indefinitely and never find a miniset, but I could be wrong. may24_04 by ellarien, on Flickr

Whohoo! Reference generates about 28 seconds on e9000! Cool!

I have seen similar "sterile regions" in other fractals that have "reflecting" aspects in their formula (such as abs(real)), or branch points. It's like they get "cut off". Are they truly sterile or is there a mini miniset somewhere?

I think no one ever found one in that region. I also took the challenge a few times but without succes.

I suppose a really tiny miniset is possible. Even north of the antenna they can be elusive -- I've just done a zoom sequence where about halfway down it passes through an 'island' that is about four pixels on an otherwise bland frame, and I'm working on one now where I got down to e200 before I found anything that didn't end up centered on a void after a few zooms. South of the antenna, though, I can't see where a miniset would be hiding at all.

I found out that the burning ship is very sensitive to the color density (divide iteration in Kalles Fraktaler). For zoom(in/out) vids for burning ship, we need an automatic adjustment or another color method altogether.

For some reason coordinates from the burning ship in fractal extreme do not work in kalles fraktaler. The whole thing looks mirrored, so I flipped the sign, but there's apparently something else going on. Which program does the correct calculations?

From memory I flipped the coordinates for FX's burning ship, to make it look like examples I'd seen online. Just checked the code... yep coordinates are flipped by subtracting the real and imaginaries eg. case FT_BurningShip: for (/**/; count < MaxIters && zrsqr + zisqr < OverFlowPoint; count++) { zi = abs(zr * zi) * 2.0 - JuliaI; zr = zrsqr - zisqr - JuliaR; zisqr = zi * zi; zrsqr = zr * zr; } break;
I've tried out a location, if you negate both real and imaginary values from Fractal Extreme it looks right in Kalles Fraktaler.

Oh, so you still have to invert the imaginary part as well. Compared to your fractal extreme plugin, it looks only to be flipped horizontally.
