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 on ...

This question is really super broad, possibly too much so, however I will try to offer some general tips for starting out in video. The most important thing with video is having a stable shot. Whatever you do, you will want to use a tripod when shooting. If you don't have a stable shot, then no amount of equipment, editing or content is going to make up ...

There are a few things you are missing, and a few more you just aren't fully appreciating how much of a difference the things you mentioned make. First, the S6 sensor is not over 1/2 inch, it is 1/2.6 inch, which is substantially smaller than a 1/2 inch sensor, particularly since sensors are measured diagonally. Second, lenses matter a lot more than the ...

General SDI vs. HDMI Information SDI is easier to connect to other professional equipment than HDMI. It is an all purpose signal, as opposed to HDMI that was originally intended only to connect to consumer display devices. There may be a slight advantage in quality where HDMI can be limited to 4:2:0 subsampling at certain resolutions, where SDI will usually ...

There are three main reasons that still cameras with video functionality have restrictions on the length of video they will shoot. The first and most common, as tomh pointed out is tax purposes. The European Union charges a 5% tax on any video recording device and sets the limit at any device capable of recording 30 minutes or more of video. To avoid this ...

There are quite a few programs that do so-called "full reference" measurement, i.e. comparing an original against a degraded signal: http://www.acceptv.com/en/products_vqa.php http://compression.ru/video/quality_measure/index_en.html (commercial) http://www.its.bldrdoc.gov/resources/video-quality-research/guides-and-tutorials/description-of-vqm-tools.aspx (...

The professional way Professionally done, all cameras and audio recorders will have a running (SMPTE) time code, which can be configured in 'free run' mode - meaning the time counter runs regardless whether we record or not (ie, STOP mode). At the beginning of the shooting day, all recordists (cameras, audio) will sync their clocks. This is done either to ...

The biggest trick you will run in to is the 4GB file size limit and the 30 minute record time limit. You will need to monitor the recording and resume several times or use a third party software like Magic Lantern to overcome the limitations. As for battery, there is a DC adapter available that you can buy if battery life is a concern.

You could use multiple cheap cameras recording at low fps, but slightly out of phase. Bennett Wilburn talks about this in his 2004 Stanford Doctoral thesis, "High Performance Imaging Using Arrays of Inexpensive Cameras".

Don't underestimate the importance of sound. Viewers will tolerate visual mistakes much more than auditory ones. When someone is speaking, background noise needs to be minimized. Remember that background noise sounds much louder on a recording than it does in person. Use a shotgun mic or a lavalier to record dialogue very close to the person speaking.

Trade in the iPad and buy a desktop or laptop that you can edit on. You will not produce professional results entirely on an iPad. I am not aware of any good video editing options for iPad, certainly none of the big names have a product available. There simply isn't enough horsepower on a tablet to perform the hard, complex operations involved in video ...

You're correct that you either need to place the camera farther away until the entire field is in view, or use a wide-angle lens adapter (not necessarily "fisheye" but wider). For indoor soccer, clearly you're limited by the walls. Presumably, you want to hit "record" and enjoy watching the game, rather than having to actively pan the camera back & ...

I hate to burst your bubble, but if you are expecting video to be a similar level of intrusiveness to photography, you are almost certainly mistaken. Video is a much more work intensive process as it requires constant attention to make sure you are getting smooth usable shots instead of the occasional random thought that "I'd like a photo of this." It is ...

I'm not being flip, but consider that not every problem has or needs a technical solution. Stage makeup can make you look any way you want to look on camera. No professional video host would go on air in his/her plain skin.

I recently encountered this exact problem and I was able to repair the file using Untrunc, a program created specifically to solve this problem, as suggested by sparrowt on SuperUser: For this method you need: another video file which isn't broken a linux installation (I used Ubuntu 12.04) and basic ability to use a command line. This is ...

To determine if a channel has SCTE-35, you will need to have the Program Map Table (PMT) recorded. From the PMT, you should be able to find the Packet Identifiers (PIDs) of all of the streams associated with the channel you are interested in. There will be a PID for the video and at least one audio PID. If SCTE-35 is present, there will be at least one PID ...

For videography, the best bang for your buck is, hands down, going to be an entry level DSLR and a decent lens. For audio, if your budget can allow for it, I suggest getting a stand alone multi-track recorder. The Zoom H4n is a particularly popular model with videographers for its low price and decent (though not superb) audio quality. (Update: The H5 and ...

It depends on the show. Some still are, but lots just use sound effects (called laugh tracks) to replicate the style of the older style of shows that are/were done live. The best bet for determining it for a particular show is to try and find tickets to the show. If you can't find tickets or people talking about tickets, it probably isn't filmed live. It ...

The best option would be either to send it out to someone that has a good capture capability or invest in a decent quality RCA capture card. The USB option will work the best of your two suggestions, but it is still likely going to be a decent quality loss (granted, VHS in general may not be that high to begin with.) The first option is not worth ...

Here is some reasoning based on numbers: You don't need a fast card for video. It is generally advised to use at least class 6 for video recording on a consumer AVCHD device: Max recording bit rate of AVCHD 2.0 is 28 Mbit/s and minimum write speed of a class 6 card is 48 Mbit/s, this should provide enough headroom even with an almost full card. ...

You could be clearer about what 'on my video' means. Does that mean: composited with other moving pictures in your video; or does it mean: in a sequence all by itself that's edited into your video? Or something else? And what video tools can you use? For compositing use a compositing tool like Adobe After Effects. After Effects would also be perfect for ...

There are plenty of camera apps in the app store that will let you lock of the exposure and focus of the iPad's camera. These are the features that I'd consider most important. Locking focus and exposure keeps the camera's settings from "breathing". This forces you to think about focus and exposure before you start shooting. This forethought is the ...

There are already 2 great answers, I just wanted to add some input that would be too much as a comment. Firstly it highly depends on which iPad you own, the camera in the first 2 generations were "garbage". I think that changed a bit with the iPad 3 and iPad Air. If the quality of your iPad camera doesn't produce suitable material you can stop right there, ...

You probably will not achieve a 100% perfect result with your setup. That you got them synced to a 1FPS accuracy is pretty amazing actually. Professional stereo setups use frame locking in hardware to ensure the cameras record in perfect sync. This is not possible with ordinary webcams. If you fix the recorded video in post you can get to less than 1/...

You are over thinking it. Edit a quick beep in before the audio starts on the song, play the song aloud while you are recording the drums. Hit one of your drums so that you can see and hear it quickly on the video as well. Record the audio direct from your drums and have a third track that is the microphone for the camera. The camera audio track will ...

Have you try to go to the product web site and check? http://gopro.com/support/articles/recording-time-in-each-video-setting I know it is about Hero2, but i think the values will not change much. Be aware fully charged battery will power the camera for no more than 3 hours

The higher bitrate will store more detail in your video. Most video cameras use file compression to throw away parts of the image that they think the viewer won't notice, in order to reduce the size of the file. Even though both files would contain the same number of pixels, areas of low detail would be compressed more in the lower bit rate image. Lossy ...

Copyright law here says that the person who shoots the footage owns the footage. The only way to change this is if you sign a work for hire contract which says that the production company owns the copyright and that they'll pay you in exchange for your work and copyright. If they didn't pay you then they breached their contract. If there was no contract then ...

It's impossible to maintain the original quality when you upload a video to youtube since youtube reencodes all videos. For a detailed explanation of why it does that, check my answer here. To minimise quality loss, export your video with a high bitrate.
