Visuals are nice and the physics are interesting. The colors are great.
Great idea. I liked the way the fluid was captured. It was a little hard to see because of the colors however.
Great idea on using sound waves to move the fluid. Song was fitting and had a good feel.
Cool concept Gabe. Love seeing how the water changes. Certain colors drained out the contrast of the water completely which was interesting. I wonder if that’s an artifact of your camera sensor or just how light works.
I like the imagery and composition of the glass and turntable, but the flow itself was not very visible, especially under certain lighting conditions. But when the water danced, it was great.
Great video, I like the music and the shifting colors. I would recommend tilting your phone to film in landscape, and some of the colors make the fluid physics difficult to see. Using a sustained note might allow the fluid physics to be more easily seen.
This video is really interesting. The variety of colors in your video refreshed my attentions and background music fits your video.
The overall phenomenon is pretty interesting, and I think it is visualized by the video. The focus could be a little better, and a tripod could be implemented to stabilized the video.
The video is fun and interesting to watch. Your choice to use upbeat dance music in this video pairs nicely with the variations in colorful lighting. Similarly, the bubbliness of the music complements the water vibrations from the bass resonance from your subwoofer. Thanks to the lighting that you use, the physics are made clear: the standing waves you talked about in class are visible.
Gabe,
Do you know how loud the subwoofers were playing or the frequency? I was just curious because I believe water can have similar characteristics for multiple frequencies and amplitudes. Also, what were the extremes you experienced when experimenting with the sound level? I really like the entire setup and I think the spin table adds a super classic vibe.
It might be cool to use a waveform generator to get a better understanding of how specific frequencies create standing waves in the water. What effect do you think securing the water glass on the speaker cabinet would have?
I really like the idea, and the post processing that went in. Maybe a little too long at the same angle? Try changing the angle throughout the video maybe?
This was a cool idea. The framing was ok, and I think the colors added to the video. I wonder what it would look like if the music was synced to the water movement more.
This is an interesting experiment. The music and lights go well with the phenomena. Did you notice any correlations between the lower and higher frequency notes and the standing waves?
Very interesting video, slow mode is awesome for this.
Amazing video, love the combination of all the light effects and music. The water in the glass is a little bit hard to see but overall great work.
I like the idea of this video, but the changing lights sometimes make it impossible to see the water. I would also recommend maybe using the music in the video. Other than that, I really liked the idea!
Nice work. I liked the lighting and your camera work. It would have been cool to do that in super-slow-motion. It was hard to see the flow details, the movie isn’t quite time-resolved.
Great video! The changing of colors added a very interesting effect to the fluid since some colors reflected off the water more than others.
Interesting resonance effects on the surface of the water creating ripples. The lighting setup might be improved if you held the light directly overhead or underneath the glass.
I like the different colors you used for the video, though some of the colors completely wash out the phenomena in the glass. What music did you use for the subwoofer? It would be cool if that music was the one in the video.
I like the way you messed with the frame rate. The colors of your setup are really strong – they kind of distract from the flow. Sweet music.
Cool effect, I really like how the music compliments the flow. The lighting changes were a good touch to the video. I really like how you were able to make it almost look like a strobe.
Nice colors and editing. Like how the sound disturbs the water.
Cool experiment and good music choice. I think this could have been better with a tripod so the camera does not move but good framing anyway.
The background was a little distracting however I liked the overall video it was fun to watch.
I really like the video overall. However, it is hard to see the movement of the water sometimes, perhaps zooming into the surface would improve this.
The overall mood and aesthetic of the composition is cohesive.
Nicely done, but I wish that the view was from overhead so that it was unobstructed by the glass rim. The lighting is fun!
I like the changing colors but at times they make the water and the flow hard to see. I would also suggest that if you run this again to try and just have the glass of water in the frame and not have the turntable in the background.
I like the idea and the flow you are capturing. The lights are really cool and I like the music. I think you could have zoomed in more and maybe have done more of an above shot but other than that well done.
Very nice visuals and good video editing. The colors make it so much more interesting. Overall nice job.
