What is a Video Converter?
- In signal processing, a video converter or digital video converter is a type of electronic hardware technology which converts an analog video signal to a digital video format, either on the input (Analog-to-digital converter or ADC), or the output (Digital-to-analog converter, or DAC). They are common in numerous technologies -notably in computer sound cards, digital cellular phones, portable recording devices, and digital audio workstations (DAW). Once converted to digital format, digital audio signals and file formats can be processed in any of a number of ways as allowed by software -including converting to audio CD or MP3 formats
How To Choose The Best Video Converter?
As of today, many of us are strong on the quality of video and audio materials stored on our PCs. This has long been a problem, because high quality vids are too large for online transfer, and it is hardly possible to compress a file without detriment to the quality. Besides, it is not always easy to find a versatile and fast-working video converter
So, you have a lot of videos on your PC you would like to convert to other formats, but you do not know which converter to choose. Here is a brief guide on what makes a good converter that will help you make a correct decision. The choice depends on:
1. The number of formats and devices supported
2. Speed of work
3. Ease of use
4. Price
5. Personal likes and dislikes
Most converters available today support only one or just a few formats. Therefore, we are often faced with the need of purchasing several programs to tailor our videos to suit different systems and devices. High quality converters support all basic formats, which include AVI, MPG, WMV, MPEG and FLV. New generation video converters also incorporate video-to-device features and therefore can convert videos to PSP, iPhone, Zune, Creative Zen Vision, iPod, Apple TV, Archos, Xbox, and many other popular devices
Speed of work is one more thing that is highly appreciated by users. Best quality video converters feature batch function, by aid of which hundreds of files can be converted in less than a few seconds. If you would like to convert all the files in a folder, this can be done with just one click of a button
All best quality converters have intuitive interfaces. This should save you a lot of brain-racking. Good converters put everything right before your eyes. You can see all your folders and files you are going to manage. Menus and buttons are readily visible upon the interface, and it takes seconds for even a novice user to understand how to handle it. Some converters feature built-in players. You preview files in both the source format and the target format. Some converters, when downloaded and installed, integrate with your OS seamlessly, so that you can manage your files right from the desktop and via command line
High quality converters combine lots of functions and modes that will get your money's worth in less than no time! For example, Total Movie Converter costs about as much as the many less versatile converters. This all-in-one video converter will do the job of ten at about the same price
Some people get so much used to old software that they don't even care to know about the progress. Personal likes and dislikes can be pretty much of a hindrance. It is advisable to keep pace with the time and use only advanced conversion tools. This will save you a lot of time, energy and money
Different types of converter units can operate at different resolutions which largely determines the resulting sound "quality." Depending on their quality and cost, converters also differ in their handling of:
- electronic (radio) interference
- signal-to-noise ratio (SNR)
- electronic noise shielding and rejection
- digital noise floor handling,
- oversampling, (input and/or output)
- simultaneous playback and recording (full-duplex)
- clock jitter
"Resolution" generally refers to both bit and sample rates (though it may occasionally refer specifically to the sampling rate; being the more variable of the two.) For example, an inexpensive brand consumer sound card for computer has a typical operating range of around CD quality - 44,100 samples per second, (44.1 kHz), with 65,536 allowable values for volume (16 bits, giving 216 values)
Digital Audio Basics:
- A single ("mono") channel (or "track") of digital audio can be visualized as a waveform, and is composed of a series of sampled sound pressures. Each sample has been quantized to one out of a set of discrete values depending on the bit depth. The playback of the waveform reproduces the sound pressure changes in sequence, producing complex sounds
- "Bit depth" determines the the number of alternative values for sampled sound pressure that can be represented. The "sampling rate" (or frequency) refers to the number of samples (or "snapshots") per second, measured in hertz (Hz)
- A stereo "track" is simply two isolated mono tracks within the same file, which are played back simultaneously. The illusion of spatial sound can be created through differences between the left and right channels. High-quality motion picture sound formats, like Dolby Surround and DTS simply use more mono channels to create more complex illusions of spatial depth
Sound Quality:
- Increasing the I/O capacity for either or both bit resolution and sampling rate will increase the quality of the sound. Multiple tracks can enhance the experience of spatial sound and sound "quality."
- "Professional" sound quality refers to highest current sound qualities for available hardware. In the past, very high resolution hardware was also highly specialized and expensive. Today, many commonly available technologies are sufficient for generating adequate or above average quality digital audio signals for use in various recording or transmission applications
- Currently it's possible to purchase hardware using reasonably high quality digital converters for well under 1000 USD. In professional uses, extremely high fidelity converters are typically sold as components within specialized rack mount multi-channel (multitrack) recording units. These typically connect to a computer via parallel, proprietary or specialized (i.e. PCI card), fiber optic, USB, or Firewire connections. USB 2 and Firewire are the most common, though Firewire has lower latency and thus is more suited for multitrack applications
- At the barebones level, audio card converters take a nominal line-level input signal and is designed to be a transparent link between the mixing board and the computer. Once converted to digital format, the sound files can be processed in any of a number of ways as allowed by software, including converting to audio CD or MP3 formats
- Both the recording and playback of sound must consider the nature of the digital medium to produce undesirable noise. The noise produced by analog tape, by comparison can be pleasing, as it is of sufficient resolution to produce "warm" natural sounding random noise. Digital recording has traditionally had the problem of sounding "cold," mainly due to the quantization effect of digitizing a linear wave into a segmented series of adjacent samples. In the case of long wave sounds, such as bass, the wave is smooth, and therefore its playback does not "jump" from a low volume bit to an adjacent high volume bit. However, high pitched sounds like cymbal crashes and similar "white" noise can only be represented by a virtually random array of bits. This random array exposes the weakness of digital playback to produce digital artifacts in the form of a high-pitched "harshness."
- While better resolutions produce better sound and less digital harshness, an important function of digital converters is to minimize the known problems endemic to the digital format. A common solution was to use separate vacuum tube amplifiers to "warm" the sound at both input output. This is generally expensive, and normalizes the sound to the range given by the tube amp, which negates the benefits of digital's deep low and clear high frequencies. The main solution has generally been to use an oversampling process, which can differ substantially depending on its application for input or output. Oversampling is the processing of sound input at higher sampling rates than the hardware actually performs. On input, this produces a digital wave which is still based on the input, but altered to record substantially fewer jumps which would produce audible artifacts. On the output, oversampling serves the same role as using a tube amp, whereby the adjacent bits are re-quantized at higher resolution to produce a smoother wave
- Given the capabilities of the digital realm to transfer exact files without analog loss, it is rare that multitrack digital to analog (DAC) converters are needed, with the exception of basic playback monitoring of stereo or specialized surround sound formats
