60Hz does not work with embed. Watch on Youtube for full quality.

Because I haven't seen many videos of people exploring this highly ornate fractal.

Welcome. This one turned out really nice! I'll be doing most future renders at 3840x2160 native, unless it's extremely deep, then I might do 2560x1440. If I see rectangles in the output video at 2x2 antialiased 1080p, that might necessitate a reencode with downsampling to 1280x720. But 60Hz shows no loss of quality and the filesize is only ~30 larger with 60fps as opposed to 30fps. Youtube uses a higher bitrate for 60Hz content so this translates into less artifacting.

For an extreme example of youtube puking on fractals:

I am currently attempting to re-encode this movie at 60Hz to reupload to Mega. A previous attempt earlier today to encode a 1080p video out of the source frames yielded rectangular frame borders so going beyond 720p doesn't seem plausible unless I reencode the movie frames. Less is more in this case. The bitrate on the old version was extraordinary, nearly 2Gb for a three minute zoom with MP4 High profile "grain" preset CQ23. I've since used CRF encoding on all my recent movies.

I may also do "HD remaster" on a couple of old zooms in the style of Simply Awesome II. Wish me luck...

That's an interesting effect, a bit like the starship Enterprise popping into and out of warp drive every few seconds.  Couldn't watch much of it without my eyes going pretty screwy.

Ouch.

No kidding. I just re-rendered my "sandstone" 3:19 AVI using "grain" preset at 60Hz, 24 CRF very slow. I had to bite the bullet and toggle "reduced CPU decode" because even my 4.2Ghz bulldozer couldn't handle the insane bitrate in the video despite being only 720p. Squeaked by with just over 2,000,000 kb or barely under 2Gb. I'll upload the improved AVI to Mega later and possibly re-up to youtube as a lithmus test. Maybe I could even rerender the zoom out frames at 7680x4320 to get super AA at full-HD. It would make a great "hard case" test material.

I'm not even sure you could encode that segment to BluRay with acceptable quality. The fact they have set top players now that push 3840x2160 native speed is unreal, but they likely have dedicated SOAC chips designed solely for decoding, something no current general purpose CPU can keep up with. I have no device capable of displaying such "4k" resolutions.

My solution is to use a zoom size less than 2. For example 1.25 or 1.5. That requires more key frames but reduce the squarish artifacts that may occur on dense pattern. I have used it for my multi-layered de movies.

I'll give it a try, thanks. I tried elliptical interpolation and it only gave me circular borders instead of rectangles.

If I use a non-integer zoom size, are those calculated on a linear or log scale? For instance, if I used 1.5 zoom ratio, then the relative size ratios between frames would be 1, 1.5, 2.25, 3.375, and so on, correct?

I'd like to revisit my sandstone zoom area and create a high quality "super AA" video at 1080p60 because it is seriously difficult material to encode and does quite a really good job at breaking video encoders. For instance, the Youtube version is atrocious. I'm also interested to see what it would look like encoded as 1080i or 720p BluRay format using maximum available bitrate settings. Alas, I don't even have a BD-R drive on my desktop!

The sandstorm location, with the glowing cracks, is really awesome!
Yes zoom size are on log scale.
Make sure there is an option "custom" in the drop down of zoom size in KFMM?
If not, I need to upload an update.

Speaking of updates to Movie Maker, do you think you could provide an offset option for infinite waves, or have it read from the kfr file? No biggie to reenter the data, but I notice there's less options in the Movie frame maker. For instance, every zoom movie I make using starts with the color teal, yet in Kalles Fraktaler, you can specify the seed value for all three components to customize the seed color. Another one, the angle for bump maps in Movie Maker is always 45 degrees yet you can specify any angle in Kalles Fraktaler.

And in case you didn't get the link, I posted an updated link on Mega for my "Sandstone" zoom movie in 720p60.

It takes up 1.95Gbytes for only 3 minutes despite using fairly conservative quality based settings (Grain, CRF=24). Handbrake FAQ recommends using the X264 Film preset, CFR 20-22 for HD (720-1080p) and 18-20 for SD (480p), for encoding movie content for local playback. I've encoded CGI animated DVDs using CFR 17 and I typically get 2Gb per hour at 854x480.

And I don't get the hubub over 4k video. UltraHD "4k" does not drastically improve the quality over 1080p when the encode quality is reduced so that blocking artifacts are still visible at HD and likely notably worse in 4k. I downloaded the 4k version of this video (from the author of the 3D frames renderer) using Youtube downloader:

Despite using an old 1600x1200 monitor with my desktop (I currently have no displays capable of natively displaying UHD content, and my 1080p ASUS monitor is tied up in my game room), the "4k" video has some noticeable blocking artifacts in places. 1080p at similar bitrate would yield a far superior image on an HD monitor, and if I notice the artifacts displayed at 1600x900, they would be much worse on a giant 4k screen.
