Welcome to Fractal Forums

Hi All!

(better see in HD)

have a nice trip!


thx!

thats an incredible voyage - must have taken you weeks to put together. Excellent!

Very nice! What program did you use? Mandelbulber? Did you use image interpolation? If yes, is that a feature of Mandelbulber or how did you do that?

Thanks :)

bib

No, i"ve used Mandelbulb3d with high resolution and calculation settings.

I am impressed by the quality of the Youtube upload.

Could you please let me know more about your settings?

- In what format did you save the frames? bmp, jpg, png?
- What size in pixels?
- Antialias or not?
- What program you use to encode the video from the frames?
- How many frames per second?
- What codec?
- What format (avi, mp4,...)
- Is the video the same size as the original pictures?
- Any tips to make great quality video like that? :)

I asked about interpolation, because of some strange effects, like at 2:52 in the top right corner.

Thank you in advance! :)

Hi !
Youtub make bad quality :(. I have 100 kb/sec video stream and youtub make 3 kb/sec.

-png
-1280x720
-x2
-adobe ae, sony vegas
-30
-AVC/h.264 (youtub make recopmression)
-m2t,mpg,m2ts
-+-15%
-(2-3)x i7 2600k 3,3Mhz@4,9Mhz +  :beer:

Thanks a lot for the answers slon_ru. I will try Adobe AE and Sony Vegas : these must be expensive programs, no? Thanks also for the codec information. And for the PC, I got a quite good one (i7 920) but I will get soon a second one (2600K, will try OC @4.4Ghz). You have 2-3 computers? Do you work in a computer shop maybe? :)

cheers

I with agree bib, unbelievable  quality!!!!  :o
Thank you for the info slon, I also have problems getting this good quality.
But I never tried x2 aa... I think it takes forever already :) But it seems to be worth it!

WOAH! 8 minutes ! that is the way i like it, be prepared for next years annual compo, each entry will have to be at least 5 minutes ;)

slon_ru are you interested in making a tv show with me ?!
i am planning for next year something likea a monthly youtube production, a news like tv show presenting what is going on in the forums, to attract a broader range of humans to the beauty of fractals...
:D

i would need some fly ins and fly outs and teasers for the rubrics, like:

 fractal news,
geetings to new users that have shout out a welcome message,
 remarkable images,
remarkable videos,
section for just describing parts of the fractal universe,
research news,
fractal software news,
weather forectast ;)

traditionally with sound ... *my xmas wish* :pray2: :)  :pray2:

Nice idea, Yes, of course, with great pleasure!

Unbelievable Quality!

Great render.

Well, everyone is raving about the quality and for saying it has been mangled and recompressed at Youtube to a 'mere' 720p, it is indeed notable.
I can't get anything decent onto DVD at 720p and so have to keep it all at AVC/h.264 / AVCHD(1920x1080) for my non-existent bluray recorder.

I can't get on with Sony Vegas, bib - I've just dumped the demo version as it has a time-consuming method of compiling pictures - and when you reduce duration, it leaves stupid gaps between each frame. How do you get around this, slon_ru? I dumped Cyberlink Power Director demo also. Much better at displaying pictures but had a 2500 image limit(!) The search for best video authoring tool goes on for me. I'm still on baby Win Live Movie Maker  :sad1: [Nero 11 will read movie maker files, meaning one less conversion process]

BTW, I particularly like the bluey-purpley things @ 6 mins. The way they ooze past each other is really cool.

cheers

slon_tu I'm terribly jealous of the quality you manage to get in Youtube!

I am really fed up with Youtube compression. I have spent hours doing tests with all kinds of codecs (including H264), sizes, tutorials, etc...and results are all crappy.

Is it because I use Virtualdub only? I don't think so, because the vids look good on my machine. Can Adobe AE really help? Not sure.

Here is my latest vid, but to be honest it's a shame to publish it after these countless hours of calculation and such a horrible result once uploaded. I will add some sound with Audioswap. Maybe it'll look better with some music :D

OK, I know there is Vimeo, but they don't have Audioswap. And now Audioswap does not offer such a wide choice as before, so I might simply stop doing videos, this is too frustrating.

Can someone tell me exactly what settings to use in the configurations screens of the H264 codec in Virtualdub? I tried this one but it was even worse than the default settings: http://www.donsalva.com/2009/03/01/virtualdub-720p-hd-settings-youtube

Gosh, you're right bib; it has really bad artifacts - unlike most of your work. What have they done to it?  I bet the original looks great though - cool location.

As you will see in my reply above, I too am having difficulty with compression (not only to Youtube but to DVD), so I am not really best placed to offer advice. You might find a program that converts to FLV that you are happy with, so that Youtube does not need to convert again. I hear that AViDemux (free) is good at this (but I have not tried it yet). I tried Total Media Converter but was not happy with the FLV result at the settings I tried. There are SO many settings to try yet though.

I have stopped using virtual dub because (1) it cannot cope with non-sequential numbered files (2) decent quality gives huge files (3) I don't seem to be able to mix frame rates for different sections that may need speeding/slowing - just one frame rate for all. (is this correct?)

Yet, all of this can be done in Windows Live Movie Maker - but it gives a less sharp finish - but - I am learning that some of this and some compression artifacts are less apparent if the original pictures had antialiaing. So I'm just laboriously rerendering some stuff @ x2AA (x3AA would take an age on top of what has already been redone) in the hope that this is part of the answer - starting with the best pictures from the beginning of the process.

If you or anyone finds the answer, I'm sure lots of us would like to know too.

The artifacts and the pixelation come mainly from low contrast areas. Usually my videos are highly contrasted, that's why it's more visible in this one.

As to your 3 remarks about Virtualdub.
(1) is probably true but you can use a great freeware called Bulk Rename Utility to rename your frames prior to throwing them into Vdub. It's very flexible.
(2) is wrong. You can use various codecs to compress your video, visit the menu Video/compression.
(3) is probably true

Yes I know it is possible to rename - but as I am prone to compile different (improved) 'takes' of anim sequences, I am so disorganised that if I rename them, I will lose which anim file created which sequence...in case I need to use them again. I guess I need to get better organised.

As for compression in Vdub; I wish I could find an authoring tool that only required a single conversion from a series of pictures to finished product. Oh well...

kam

well, if you read this, bib, I'm quite pleased you were also struggling to get a good compression as, because of it, you posted this link to the H.264 tutorial for Virtual Dub
 (http://www.donsalva.com/2009/03/01/virtualdub-720p-hd-settings-youtube).
Following it, I have finally managed to get a very low file size vs v.good visual quality at 720(!) All I need now is to get it to stop stuttering as if it is only @ 5fps.
(another reason to have stopped using it). Thanks, it works, folks.

Kam

Do you mean on your PC or on Youtube?

Ah, a good point.

Just on PC at the moment. As I said, this has been a problem area for me.
So, having the day off, I spent some of it fiddling with settings and some old test renders.

Youtube test still to come...

I would qualify my 'v.good quality at 720' comment by adding that this is only because
of the remarkable reduction in file size that makes the visuals acceptable.

My issue at present isn't really in getting a small size, but getting the highest quality onto
a DVD - (so I can allow 4.7GB). At this range, I expect near DVD quality, just not full HD,
but, alas, converting full HD down to VOB files really hasn't gone well so far.

Youtube is a different issue, but I have seen some of my 720 conversions go ok, really.

Bib, Your artifacts come (imho) from the M3D, not from the codec, try to increase the quality of rendering.
For gud codec quality try this:
http://www.fractalforums.com/fractal-related-links/mandelbox-animation-t10212/msg40802/#msg40802
Best regards!

slon_tu, yes there are many artefacts that come from M3D but this is not the problem. The problem is neither the codec. The problem is that Youtube compresses video horribly. I am sure that there is a way to minimze this effect, maybe by saving the video in a format that Youtube will recognize as already compressed like it wants so it won't compress it anymore. But honestly I have spent way too much time doing tests, so I give up.

Bib, for good quality of video you need about 20.000-30.000 kb/s bitrate, It"s really does not matter which codec you use, but youtube make it 2000-3000 kb/sec max. Abandon hope ...
sorry for my english.

No problem with your English, mine is not much better :D

But still, I am impressed by your video. I am sure that if I had done the same and uploaded to Youtube it would be totally pixelated :D  :surrender:

Bib, sent me pm your m3a file and i try make 10-20 sec "clear" youtube video. We'll see. (i can do it after 02.02.12, i"m on vacation now)
br

Hi Bib!
Ufff, I going back home on my vacation!

I can"t make video better - Min R parametr is to high, fractal is not "stable". imho - make im low (0.5-1.2).

For pure video you need a better source :)

Thank you very much slon_ru.

No problem with the fractal parameters, what I was interested in was the Youtube compression, and it seems you did a better job than me. Did you assemble the frames in Virtualdub, can you tell me the detailed settings of the compression method you chose?

thanks

bib

Hi bib,

I"ve rendered you m3a file with Raystep mupltiplier=0.1 and Max. iterations=2000 as *.png sequence.
... loaded sequence in VDub, applay "levels" filter (not necessarily).
... used free XVID codec, with quantization=2 (codec setup/quantization.).
... saved sequence as avi. Video have >20.000 kb/s bitrate (90 mb).
... load video in youtube and vimeto, if i save my Vido back, it is 3.000 kb/sec (3mb) only ! :(
p.s. for "slow-time" effect need you  adobe ae.
sorry for my english.

OK thanks

Im jealous, simply wow!
