Show HN: WZRD – Visualize your music with StyleGAN

I'm ok with you storing my password, I'd create a unique one, this seems secure.
I don't want to log in via Google though, I see it as less privacy friendly.
It's also arguably less secure; if my Google account is compromised, the attacker gains access to other services.
Email/passwd auth coming in the coming week.
Loved the visuals. I can tell that your analysis separates out harmony and percussion as advertised as the video reacts very well to transients in music. This is a common criticism I have of music visualizers--often they don't react to transients quickly enough to communicate the percussion patterns and that's not an issue here.
The whole process creating the video was very easy. Some more control over the images used would be cool, but I'm not sure how that'd work. I do also like that the images are generated and unique for each project. Perhaps if it's possible there could be an advanced feature to upload a pool of images to seed the generation of images. For example, if I wanted to create a video using landscape images of a particular type (mountains, forests, etc), this kind of feature would be very useful.
I'm not sure I'll be a paying customer for this product, as I don't have a commercial use for music visualization at the moment, but I'll be playing around with it some more for sure. I have a big collection of synthesized versions of classical music I created for a project that never materialized, so I can see using this tool to revisit that music and perhaps create videos to share. Thanks for sharing this very cool project!
If there is a paired dataset, I guess this could be "easy". The stylegan "input" is essentially used to control parameters at various stages within the network, so you could adjust them one at a time, or on varying schedules or something, to get the sort of gradual effect.
I know that randomly instantiated neural networks can produce some pretty trippy image transformations as well, so maybe there is a way to bootstrap without paired data.
Lastly, I doubt this is on the right track but it would be cool if you could produce appropriately styled images with a "compression" approach. ie, trying to fit the audio information into some small visually meaningful latent space, and then using that to generate images.
edit: ok just watched the first example, back to square 1 for me. Its literally pulling stuff from paintings.
My co-founder has a YouTube channel where he will be going into technical detail how this all works. He will be posting a video in the coming weeks. https://www.youtube.com/channel/UCNIkB2IeJ-6AmZv7bQ1oBYg
Also out of curiosity, did you determine anything about the legality of training the GAN on copyrighted images and decidings its output is its own creative work, or using public domain images?
Firstly, like others have said, I don't want to use Google to sign in.
Also, why must I sign in? This seems like a tool and thus doesn'y need a login.
Which makes me ask... what's the pricing? When I do "sign up" do I only get one video? one minute? a limit of some type?
Also, what's the legal? Do you own the video? Can I monetize it?
An FAQ can probably help answer the above.
Google -> fair point, we’ll add some more options
Signing in is needed though. We could maybe find a way without it but it would be a bog hassle. At minimum we would need an email adress for when the render is done.
For now, we have a very basic pricing scheme. We add a subtle watermark to the video. If you pay to remove it, all the renders (also new ones) for that project will be without watermark. For now, we don’t put any limitting, except on audio length and file size. Do you think this is a fair model? Or would something else be better?
Legal -> it’s your video. But we’re not responsible for storage.
If you know someone from the GCP team (sales/support), please let us know! We would like to increase our GPU instance quota.
1. Upload your audio track
2. Pick a visual theme
3. Render your video
Enjoy!
Any feedback is welcome!
You can always look up a song on youtube and use youtube-dl with the audio flag to grab an mp3 file, if you really do want to try it out
As a developer of VJ applications for more than 25 years, it deeply resonates with me.
I will wait to be able to create an account with my email rather than using google to play with it.
| I watched the 4 example videos. While impressive, the first one has so much flickering that I had to stop watching it. The second example is perfect, and you feel very well the connection to music. The third one got me lost; I am a big fan of ambient and cosmic music, but the result did not seem connected. The fourth one is much better, and you perceive the waves of the musical input very nicely. |
While using a very different technological approach, the three videos from the right side have a lot in common with the results of Shadertoy.
Many music videos on YouTube are just a static picture; there is an excellent market for your idea. Maybe try to have more examples based on what you see prevalent on YouTube.
It is possible to make that optional and by all means you should - that is possible with google sign in scopes. Even if you want my public profile info and not just my email that should be optional.
- FB - Twitter - Apple - Would email+pw be necessary? I’m maybe biased, I generally prefer using and implementing third party authentication.
I would consider using Apple for something like this. But limiting it to third-party auth is pretty unfriendly to users.
- FB is not that easy, since you can't set the email address as a required field. We use that to send the final render. We could let it be filled in in the app though.
- Twitter will probably be added
- Apple can be investigated
It's a pretty costly operation since the marginal cost is very high compared to other SaaS products. We'll probably iterate on the pricing model.
What do you think a good model would be?
What sort of worked was I routed the data so the inference ran on my own local server (i.e. my work station), although the downside is you can't use your GPU for other stuff. At the time I looked into it, 3 months of cloud server costs were enough to buy your GPU work station. Also tried to do whatever I could to optimize inference.
I have no idea what kind of volume your getting but I imagine itd be even worse for video based Gan stuff. Maybe go for quality an target super high end? You probably have a much better idea than me.
All the best, will be interested to know how it goes
