My phone camera does slow motion as well. (Slow motion solder smoke) - Page 1

content: I need to find a black backdrop to take a better video but the slow motion on this camera is pretty sweet, except for the fact that I can't find what actual framerate it's taking video at.Now sure I'd love to be able to zoom in and be 1000x slower as the solder touched the iron, but for something in your pocket it's pretty cool.https://youtu.be/5srCIanPChY

content: It looks about half speed to me, never mind flux smoke, let's see some electrolytics or chips popping.

content: Alright damn this was cool, but also shit I need to add a switch to bypass the fuse in this thing lol. I pulled it out and it had a dead one, I guess this resistor was too much for it.https://youtu.be/CVyXHeBg0EUDon't think I have any low enough voltage caps sitting around to blow with the stuff I have sadly.

content: "I feel like it's a lot slower than half speed because I can record clips of fire and it's pretty impressive"I know what you mean, but from experience, half-speed often looks slower than you might think.All you've got to do is video a digital or analogue clock or timer for 5 to 10 seconds, and then time the video's playback of the 5 seconds."Don't think I have any low enough voltage caps sitting around"You can reduce their voltage rating by connecting them up the wrong way. ( or so I'm told)

content: Alright, so it's 960x540 video at 120fps, which is 1/4 realtime. That's some nice quality slow mo video.Although with that said there are phones out there that do better slow mo video - the iPhone 6S does 1920x1080 at 120fps along with 1280x720 at 240fps. The Galaxy S7(e), HTC 10 and Nexus 6P also do 1280x720 at 240fps.I assume this is because the 12mp sensor in these phones can be read out much faster than a 21mp sensor without serious cropping, and the chipsets in these have the encode blocks to encode at the higher data rate vs the Snapdragon 615 in the X Play.What I would like to see though is 1080p240fps - that would be a killer feature for me on any phone.

content: Quote from: encryptededdy on July 08, 2016, 10:53:30 amYeah I wish it was higher resolution too, but honestly, to trade off lower quality slow mo for the ridiculously good 21mp camera is well worth it.

content: Quote from: XOIIO on July 08, 2016, 06:22:50 amMoto X Play has a Sony 21 MP (20.7 MP acutally) sensor in it. My 3-generation-old Sony Xperia Z2 has (probably) the same sensor in it... Sony keeps their latest, best sensors to themselves for a generation or so, to give their flagship phones a leg up on their competition. The old Z2 can do 1080p @ 120 FPS, or 4k (2160P) @ 30 FPS. It's a nice camera, comparable or better quality to most pocket point and shoot cameras, except for lack of optical zoom.The slow motion can look really great if you put the file onto your computer and change frame rate to 24 FPS (without processing) then play back on a TV with the motion compensation/interpolation set to high. The result is 1/5 speed and very smooth (due to the TV's processing).
