With low light levels your brightest signal will be close to the noise floor, so you only really have three options: a camera with better low light performance (although this can only take you so far) More expensive sensors can give a lower noise floor, allowing you to resolve more detail a faster lens As Jason commented: If the widest aperture ...

There is indeed no technical limitation that would prevent us from preventing vertical videos in software. The issue is more of an UX/usability problem. While the sensor would allow us to capture virtually any part of it (video has usually always a lower resolution than the sensor can provide, when making videos the phone just records a small portion of the ...

You will pay substantially more for a good 4k camera right now than you would for a good 1080p camera. Quality =/= resolution, there are phones that can shoot in 4k but the videos will look a lot worse than a 1080p video from a dedicated 1080p camcorder/dslr, the image quality depends on a lot of factors. A bigger sensor for example has the ability to ...

Does youtube store different video files for different bit rate? Yes is the technique called "resampling" ? No Does youtube make live resampling for every user ? No All this things happens live ? No, not on youtube. But Yes on twitch.tv Or it encode and save different video files for different bitrate, so that when a user ...

You're going to need to do a little experimentation to find out what works best for you, but here are a few things to consider: First, the minimum amount of light you need depends on the performance of your camera and lens. Stanley Kubrick shot parts of Barry Lyndon in candle light, but he used a f0.7 Zeiss prime which was built for NASA and customized to ...

After seeing something similar and wondering how it was done in a video with a guy, girl video looks edited. I tried this, and think that he actually is writing on glass, is filmed from front, with mirrored letters. After filming just simply flip video horizontal, and text will be mirrored back to normal and guy will be mirrored. Just make sure there is no ...

I'd argue that for casual shooting (family, travels etc) you are not going to carry an expensive bulky camera, you are likely not going to carry anything on you… except maybe your mobile phone. So I would look into buying a cheap mobile 4k device. Two good looking recent mobile phones able to record 4k are the Samsung Galaxy Alpha and the Sony Xperia Z3. You ...

I agree with your assessment that 4K isn't ready (or affordable) yet. Consider what you want to shoot, and what you're willing to carry around to do so. Then find a 1080P camera within your budget. As already stated, the total resolution isn't as important as the sensor size/quality, lens quality, in-camera compression (the less the better), and ...

You are almost certainly up a creek with no paddle. Since video is less than 8 bit color, what you see when you watch it is what is there. If there was some small amount of detail but it was just really dark, then you could alter the white point and get something minimally usable out of the darkest part of the image. This can be done with any decent ...

You could use the 30 days trial version of Premiere Pro (most editing programs will be able to perform the following options). The best way to make the video viewable depends on how badly the video is underexposed. If some areas are literally pitchblack, there is nothing you can do about it. First, try to use the brightness and contrast effect and raise ...

I've never heard that term used for rendering before, but it is most likely referring to the number of hours of computation needed for a single CPU or GPU to process it. In most video and 3d applications, it is possible to parallelize the rendering of the video itself (though not necessarily the encoding. Thus, a job that would take 200 "man hours" (more ...

Just to add a little bit more info to SlimSCSI's straight up answer. Does youtube store different video files for different bit rate? Yes and no, for the 1080p stream YouTube utilizes a technique called DASH. This serves essentially a video that was encoded with several different bitrates (though its one file) and adapts the bitrate on the fly ...

While I mostly agree with what Professor Sparkles says above, note that Google is attempting to convince people not to film vertical video. In this YouTube video they show the new overlay that is displayed while filming vertically on Android phones, gently encouraging the user to turn their camera.

The Wikipedia article on MPEG-4 is a great start as the MP4 file specification is part of the MPEG-4 spec. Specifically version 2 of MP4 is MPEG-4 Part 14. While not free, you can purchase copies of the ISO spec under ISO# 14496-14:2003. A preview with some detail is available from the ISO here. It is designed to contain any of the various MPEG video ...

Professional film makers generally use audio recorded separately from the video on dedicated recorders using professional mics (using XLR cables and the like). 3.5 mm audio connectors in particular are almost exclusively a consumer level connector. So for a professional level, the answer is use something like a Zoom h4n, h5 or h6 and microphones of your ...

I recommend VVVV also. You could make a patch that controls many video effects with levels from microphone input. Take a look at Video Effects and Compositing Tutorials Basic tutorials and examples on how to use TextureFX nodes to work with the same tricks and techniques you could previously achieve only in Photoshop or After Effects. And what's ...

There are several programs available that allow you to do that. One very popular tool in the live visual industry is MAX (especially Max for Live). Its a visual programming language to create visuals for live performances that also integrates into a few tools like Ableton Live. A program that I personally use at work is called vvvv, its a visual programming ...

This is a "very" old question, but there is a pretty simple method to do this (and something that comes up surprisingly often). So if you landed here, I do hope you find this solution helpful. Change the individual slides to pdf. Turn the pdf to jpg Turn the jpg's into a film. To do this I have used unoconv, ghostscript, graphicsmagick and ffmpeg. ...
