Even if digital video capture is easier than ever, not everybody can make an art from it. It does look simple when you seem someone else performing the task, shooting the scenes with the video camera and then downloading the stored data into the computer. With a few clicks you may expect to create some cinematic masterpiece. This is a tricky occupation that requires skill. Digital video capture is possible by the compression and decompression of data through digitized encoding: there is no other way to handle the process because of the large necessary storage space required.
Things used to be simpler with the compression-decompression process for analog videos. Yet, image quality was sacrificed all the time. Capture digital video involves a superior technological process, and it represents a step forward in terms of quality video shooting.
The solution for the compression-decompression process came from the invention of the CODEC algorithms that work for the adjustment of the video to a computer by digitizing and compressing pictures. PCs often come with pre-installed CODECs, particularly the newer models. CODECs can also be downloaded online. JPEG and M-JPEG algorithms enjoy the best reputation. Digital video capture therefore has a complexity that the regular camcorder user does not even suspect.
The best type of digital video capture is performed with a special type of capture card also known as firewire or IEEE. Without the use of this card, lots of quality of the material is lost during the transfer process to the computer. It’s a pity that advanced digital video cards are very expensive and therefore, harder to get by the average consumer. This does not mean that you can’t get decent quality for a good price too.
The transfer rate of the stored data is very important for digital video capture, and you should look for devices that allow a transfer rate of up to 400 Mbps. These are the easiest and most efficient to use. The ports in the new computer models are built in to easily use the card, so that you don’t have to improvise. You should nevertheless check the Open Host Controller Interface compliance in order to make sure that the digital video card is compatible with you computer or notebook.
