For someone with limited experience, converting VHS tapes into a digital format can seem as simple as connecting a VHS player with a DVD recorder. Unfortunately, if you want at least adequate results, the process can quickly become much more complicated.
Many tools play a role in that the quality of the video does not deteriorate and that most of the imperfections are corrected.
One of these tools is a TBC video filtering device, which can be the difference between a jittering and grainy image and an almost-flawless result that you can be happy with.
But what is the TBC video filtering device? And why is it such an important part of the VHS to digital service?
Let's explore below.
Before we can delve into the details about why TBC video filtering is essential, we need to understand what it is and how it works.
Basically, the TBC video filtering device is a tool that serves as a barrier between the analog footage that is transmitted and the digital format that it is eventually converted to.
By sending the footage through the TBC video filtering device, you can eliminate various issues and correct errors in real-time, ensuring that the digital version's quality remains consistent throughout the entire video.
Although the origins of video correction date back as far as the 1960s, TBC video filtering remains a vital tool of any video conversion service provider, as the device can make the entire process of digitization much easier.
Even with today's advances in digital technology, there's still a place for TBC tools that are well-equipped to handle the challenges of working with analog footage.
In fact, while the basic principles of the technology may be simple, it usually saves a ton of time in editing and post-processing, solving the problems during the transfer by simply ensuring that the signal remains consistent and synchronized.
Now that we've understood what TBC filtering is, we can look at some of its primary functions in digital video transfer.
Below, you'll find some of the most common issues that can be addressed using a TBC video filtering device.
Jittering is one of the most common issues with analog videos. It is basically the process of data being lost in transmission, which can cause distortions to the footage when transferring it to a digital format.
If the channels are not synchronized, that can cause a range of problems, and jittering is one of the most prominently visible ones in terms of distortion.
Jittering can be horizontal and vertical, both in both instances, a TBC video filtering device is the simplest and most effective way to handle the problem.
Trying to remove jittering using video editing tools is a long and challenging process that requires a lot of manual labor. Even then, there's no guarantee that the results will be satisfactory and that the image quality will be improved.
Meanwhile, with a TBC video filtering device, you don't have to worry about correcting the digital video manually. The tool handles the process in real-time as the video transfer takes place, ensuring that both videos start at the same time and are able to send and receive the same data simultaneously.
If you've ever watched a VHS tape, chances are you've stumbled upon top-screen tearing at least a few times before. Because of this issue, up to 20% of the screen can become distorted, becoming blurred and almost impossible to make out.
Since this is another issue caused by timing problems, TBC video filtering can usually handle by ensuring that the video is synchronized and that no part of the tape gets left out.
Sometimes, you might also need to use a stabilizer in addition to the TBC filtering device to achieve the best results. In worst-case scenarios, even both of these combined won't eliminate the problem. However, experienced VHS to digital service providers might be able to find a solution or at least professionally crop the video.
Rippling, also known as the clear-water effect, is another common problem that arises when digitizing VHS tapes. This problem gets its name from the way that the video resembles small ripples in the water.
The error is caused by timing issues in the analog tape, and the footage needs to be synchronized in order to remove the problem.
Once again, post-processing can be of little help when trying to correct this, as there is simply too much manual work for it to be feasible for almost any footage.
Luckily, the TBC video filtering device comes to the rescue once again, removing the problem in real-time as the video is being transferred to a digital format without the need for human intervention.
Finally, without TBC video filtering, you would likely run into various contrast issues that would be caused by the inconsistent or damaged signal that distorts the colors.
Usually, the flux presents itself with sudden shifts in brightness and contrast levels, changing more or less every minute for the entirety or the majority of the footage.
Sometimes, the problem can be caused by anti-copy measures put in by the manufacturer, but for home videos, the most likely cause is signal damage.
Luckily, a TBC video filtering device can typically handle the problem by ensuring that the signal is stable throughout the transfer process.
It is possible to remove the issue using editing software, but the technology and software required typically are well beyond the means of a casual consumer who wants to digitize their home video collection.
A professional video transfer service provider might have the tools necessary to correct the digital footage, but it would be much easier to prevent the problem in the first place using TBC video filtering technology.
