Repeating Zooming Self-Silimilar Thumb Up, by Craig

It sounds like it is going to be an interesting zooming video.

I have added buttons for finding the closest prime-numbers for the waves in order to avoid them to align.

The guessing of pixels in kf is not so smart, it starts by calculating every fourth pixel and then compare nearby pixels for the rest 75%. I too little knowledge in the other methods that I know exist for pixel guessing

I have added buttons for finding the closest prime-numbers for the waves in order to avoid them to align.

Yeah I'm aware of the prime thing, but the values don't need to be prime to be relative primes. Thing is, close but not exact alignment is desireable in this case due to the 1571 period of the onion like layers. All three values should be near miss factors. Having a smallish LCF like 2 or 5 is insignificant. What's more important is the rate of deviation between each layer. So if the actual period between layers is 1571, then the coloring algorithm between spirals becomes the difference to this value. Using my next set of experimental values,

Hue=1571
Saturation=522 (*3=1566)
Brightness=315 (*5=1575) or 316 (*5=1580)

The onion layer increment becomes:

Hue = -1
Saturation = -5
Brightness = +4 or +9

Color cycling each frame on top of this will have the effect of retrograde cycling especially noticeable with hue. The pallet itself will appear to change independently of iteration depth. Otherwise if I didn't take period into account, each layer wuld vary wildly from the next and the entire zoom sequence would look like fruit salad.

Try tweaking your periods. You can vastly change the color patterns in a Seahorse or Elephant valleys, or even make a spiral go chameleon like and nearly disappear!

= = = = = = = = =

My general strategy for "normal" zoom sequences is to forgo primes in "normal" zoom movies for the Fibbonacci sequence. The series diverges on the golden ratio between consecutive terms and it is proven that any three consecutive terms (besides 1) in the sequence are relatively prime.

1-1-2-3-5-8-13-21-34-55-89-144...

Brightness is the low value, saturation is the middle, and hue the highest.

Funny thing. The golden ratio minus one is it's reciprocal. Plus one is it's square.

BUMP. So I'm redoing the animation with the following color cycling:

H=1570
S=522 (S*3=1566)
B=225 (B*7=1575)

1920x1080p60
60 AVI frames per zoom frame.
60 AVI frames per second.
Cycle colors +1 per AVI frame.

The first 3 minute AVI segment (10800 frames) using the new color cycling is finished and I'm liking the color balance. The bulbs almost tend to melt in and out as the luminosity changes. Here's a screengrab  of the approaching minibrot flyby from earlier this afternoon.

The PC finished rendering the AVI frames this morning and I'm joining them in AVIDemux. I have to use zero latency option when joining AVI segments otherwise it drops a few frames at the end. I'm using the advanced H.265 codec for the first time and reencoding to MP4 container. 1080p60, 14 minutes and something. I think we'll see tremendous gains in quality versus file size with H265 due to the advanced motion detection. I'm using the default settings except I changed motion detection to star search. Only thing with H265 is set top boxes and mobile devices probably don't support it yet. tease

Youtube will probably ruin it again so I'll be posting a Mega link as usual.

BUMP. See first post. grin grin grin

Going to bed; got busy day ahead of me tomorrow. Later... sleeping

EDIT: Upload failed. Youtube not support HEVC. And I'm not convinced it is ready for prime time yet. I also had to install the K-Lite codec pack on my 8.1 laptop to be able to play it. Also there were some noticeable compression artifacts in the output so I'm not completely satisfied with the results.

EDIT2: Reencode complete and currently uploading. H264 (CRF=24, slower) actually resulted in a smaller file with better temporal quality than the HEVC test. Should be live in a few hours. For real this time. tease
