There are a variety of reasons to have an external recorder depending on the size of your production. A big advantage is the number of audio inputs and the ability to record each of those inputs as separate tracks, allowing you to do the mixing in post. I'm not sure about the H4n, but I know the H5 and H6 support multiple inputs as well as interchangeable ...

Yes, its way better. Being able to monitor the levels, and headphones, makes a huge difference. However, its not even just the quality of the mic or recording device its the location. Having an external recorder means you can separate the audio easily from the camera. Back in the day when I was a teen, and had more enthusiasm than money, we used mics from ...

Can't speak for the Nikon, but the Canon 5D and 7D both have terrible on-board audio, with no way to easily monitor the audio levels. The Zoom will have a better mic pre-amp, and will let you monitor the levels easily and accurately. You can also monitor the audio on headphones whilst filming, so you'll stand a better chance of spotting problems, like wind ...

File format Bit rate tells surprisingly little about quality in the case of mp3 files. There are old encoders where no matter how low you set the compression, there will always be audible artifacts. But LAME and the like have long gotten over this, and properly done 320 kBit mp3 is for listening purposes lossless, just like CDs are. Note anyway that mp3 is ...

"Ducking" is the canonical term for what you want, usually done with a compressor in the main program chain with the sidechain taken from your mic channel. Audition 2018 has a auto ducking feature that may be of use, but really anything that lets you drop an audio compressor across the program bus and sidechain it to the mic input will work.

The attachment you are looking for is called a lav mic, though sometimes it can be a hand-held shotgun mic, too. Sound intensity decreases as the square of distance and echoes decay exponentially. The trick to eliminating the echo is to get the mic sufficiently close to your sound source that the original source is 10dB to 20dB louder than the ...

What you want is generally called an "HDMI audio extractor". There are several hardware products on the market that will extract the audio in the HDMI stream to an audio out connection and pass-through the video part. A search on ebay gives you several results: http://www.ebay.com/sch/i.html?_nkw=HDMI+audio+extractor Though if you need very high quality ...

Complexity is the main thing. Because of how audio works, there tends to not be a whole lot of variation in the quality you get from a given bit rate. While video often has frames that are very similar from one image to another, audio rarely has the exact same sound playing for a long period of time. This lack of predictability in audio means that the ...

It's also known as having an solid understanding of microphones and recording techniques, as well as sound audio editing principles. These types of videos are a great example of how awesome sound recording can enhance picture, and examples of the reason no filmmaker should skimp on sound. It's easier to mess up good sound for dramatic effect (say, adding EQ ...

It sounds like you are using your laptop's microphone, and that your main problem is the lack of a quality mic. If you own an iPhone, especially iPhone 5 or later, I would recommend you use the voice recorder app, and email the audio files to yourself using the Share button. The iPhone's microphone is surprisingly good for audio. High end Android phones also ...

There's no single answer - it's a series of trade-offs: When you record your voice, it should be as loud as possible, but making sure never to go over the maximum level that can be recorded. This is known as clipping, and sounds distorted. Too quiet, and your audio will be hissy relative to the noise floor of your setup - too loud and it will clip. In ...

Apart from the other benefits mentioned - mic placement, quality of the pre-amps, ability to properly monitor levels, another advantage is that many of the good quality digital recorders (like the Zooms) will let you record 24 bit samples at up to 96kHz. To use a not completely accurate analogy, that's like recording raw video at 4K instead of 8-bit at 1080p....

I wouldn't recommend the h4n anymore. It is still a huge step up from the on-board audio, but it generally isn't the best value anymore. The H5n or H6n are both better options available now and generally better value unless you are getting a used H4n that someone is selling so they can buy the 5n or 6n. That said, yes, you want an external audio recorder. ...

Getting the audio recording separated from the video recording is one of the best things you can do to improve your sound. What makes good camera placement doesn't always make for good audio placement. Also, your audio recorder can keep running while your camera isn't, so you don't miss anything. That being said however, the zoom h4n has some mediocre pre-...

One that comes to mind is Presonus Studio One vr3 It is about $50 and is a full featured digital audio workstation. There is also sonar, protools and ableton live but I believe they are all quite a bit more expensive. Good luck!

90% of good sound quality is mic placement. The remaining 90% is the microphone. The 90% that remains of that is the preamp. Because mic placement is so important, you either have to accept putting the video camera where the microphone sounds best, or you have to disconnect the two, placing and pointing the mic where it is best and then placing pointing ...

Davinci Resolve 14 would definitely do this as it has all new audio, otherwise Adobe Premier will work

Without more detail this is not directly answerable. The short answer is, the shorter the better, but the long answer depends on many factors. The amount of electromagnetic noise in a room will impact how much the cable picks up noise by working as an antenna. The type of cable being used will impact how much shielding prevents cross talk (between ...

You may want to consider looking into another alternative as well: double-system sound. The (old school) idea being that since you have a separate recorder, you don't need a connection between the camera and recorder. Instead you can record both separately and then sync them in post-production. If you do this, it's highly recommended to use a clapper board ...

I would suggest trying to combine the two audio feeds. If you layer the room audio with the clean audio, it will probably help make things more usable. Otherwise I would give the customer what they asked for. Ultimately, I don't think it is your failing to have had blown out room audio when there would be no good reason to use the room audio. As an aside,...

The choice of container has no bearing on stream quality, which is determined solely by encoder parameters. What may happen is that the stream could have non-standard or at least unexpected colorimetry properties and some containers can't store that metadata or may have stored them incorrectly. Also possible is that the metadata is correct but the player ...

If you aren't adverse to using a terminal to extract it, FFmpeg is a very good tool that you can use. The command that you'd want to run in ffmpeg -i [input file name here] -c:a copy -vn -sn [output file name here]. -c:a copy: This argument copies the audio stream of the file. -vn: This argument informs FFmpeg to not account for any video streams. -sn: This ...

Commands are instructions sent from an interface external to the filter, usually an external program using a ZMQ protocol. There is a filter that can execute commands which is what I'll use here. Base syntax is ffmpeg -i in -af "asendcmd=c='0.0 afftdn@n sn start; 1.0 afftdn@n sn stop',afftdn@n" noiseout.wav To use another source for noise profile, you'll ...

You'll get the best audio by connecting directly to the board the sound guy is using. As you mentioned, the risk involved there is that you lean heavily on the sound guy and hope he doesn't screw up. If it's an option (depending on what kind of setup he has), sometimes he can record all the audio to a CD for you. This would almost certainly be possible if ...

You can use portable recorder like Zoom H4n or similar. Recorders like this usually have XLR input that could be plugged directly to mixer. You'd then set input type on your recorder to line-in and set its sensitivity to have your levels not too quiet but not clipping (exceeding the scale). You can also plug in microphone and try to do the same however ...

This answer (and the video link included within it) tells you all you need to know. The long and the short of it is that good audio is essential to good video, and getting good audio requires its own set of techniques, practices, considerations, and, in many cases, gear. Sound attenuates at a 1/(r^2) rate for point sources. Unfortunately, an automobile ...

Premiere doesn't change the audio levels (volume or db) by default. So I'm not sure why you are experiencing loss in volume. My guess would be that you have turned down the audio levels in premiere by accident. Or that you are incorrectly comparing the files (have you checked the waveform to see if they are different levels?). If you changed the audio ...

You can use Audacity for this purpose, and you can follow this link to learn how: http://manual.audacityteam.org/o/man/tutorial_click_and_pop_removal_techniques.html Generally, clicks are little bursts of noise (such as a small scratch on a vinyl record), and pops are larger bursts of noise (such as a large scratch or a plosive "P" hitting a microphone ...

You could also try a lip mic, like the Coles 4104. They're used in very noisy environments such as football matches by commentators, and work well. Just holding any mic very close to the person speaking won't necessarily sound good, due to how the microphones response changes when close to a source - you can get a lot of bass tip-up and popping from some ...
