A bit of data extraction from audio. Using #python and #houdini

This kinda exploded. While you're here check out my OnlyFans: sunmachine.io

"What bitrate should I export my mp4s in?" I used to wonder this until I found a formula in an old PDF that an Adobe employee created over 15 years ago. I turned it into a little calculator for everyone to use: bitratecalculator.app

@RadekDubisz it should be fixed now, thanks for mentioning it!

@der_flow_ I dunno if you intended the dropdown to look like this (I hope you didn't). This here's Win 11, Edge browser.

@simohn I have added it to the website now! Thanks for the great idea!

@der_flow_ With an target sice of the file would be useful. I sometmis hafe to deliver 4mb files. And the 5th trial n error export matches that...

@FallenGayms I agree, that's why there's a motion complexity setting. It acts as a multiplier depending on how much is going on in the frame.

@der_flow_ And the type of content displayed has a big impact as well

A little music visualisation experiment. More info: sunmachine.io/work/light-for… #dataviz #musicvisualization #houdini #ebsynth #suno

@oyacaro exactly, that's why you can choose the motion complexity, it acts like a multiplier. if you hover over the icons it explains what they mean.

@der_flow_ whats inside the video? thats what matter for bitrate not just number. you can get worse quality on higher bitrate depending on the video content. not so simple

@RadekDubisz thanks! Working on fixing this!

@banteg ok bro

@der_flow_ nobody uses bitrate mate, just export with crf 16-19 and you’ll get the same quality throughout.

@fagtress Interesting, I'll look into that. I wasn't aware of this, never came across it.

@der_flow_ no this is completely wrong, and all modern h.264 encoders support CRF. CRF is a number, usually between 0 and 100, which corresponds to a perceptual quality level. for example with x264, the best h.264 encoder, a CRF of 18 is generally not noticeable in motion

@simohn great idea! I'll build that in!

@eneri74362847 w × h × fps × motion × 0.07 ÷ 1,000,000 = Mbps VBR target = CBR × 0.75  ·  VBR max = CBR × 1.5 it says at the bottom of the page :)

@der_flow_ What is the formula?

@GamingOblivion editspecialists.com/DCTRAINING/h26…

@der_flow_ Can you post the PDF as well? I'm curious.

@onyxx____ I think CRF refers to the same thing as VBR (in Adobe apps)

@der_flow_ See there's this beautiful thing called CRF...

@fagtress I come from the After Effects / Adobe encoding world. I've never heard of CRF but a quick google says it's just another word for Variable Bit Rate (VBR, as Adobe calls it) which is what the site calcualates for you.

@der_flow_ why not just use CRF? it gets you better quality at the same bitrate, adjusts based on how hard the content is to compress to target the same quality and is built into practically all modern video encoders

@DinoMFX Ha thanks, the article is very much outdated, and I recommend EXR DWAB for most use cases but the point that PNG is a nightmare still stands :)

Because I still see it done way too often. DO NOT USE PNGs Use EXRs 💪 derflow.medium.com/why-you-should…

Human vocals → data → particle simulation. This visualization extracts vocal features and uses them to drive a particle system in Houdini. #houdini #synesthesia #audiovisualizatioin #soundart #mograph sunmachine.io/work/acoustic-…

@simonfarussell this looks so sick! probably my favourite of these recent explorations!

Another test experimenting with visualising audio. This one’s a thrush. I analysed the recording in Spear, then rebuilt the spectral data inside Houdini with Python. #houdini #audiovisualization #sonification sunmachine.io/work/acoustic-…
