How do old cameras collect data?

_ The tape camera cannot capture video via USB.

_ Only through video capture card 1394 interface or av/S terminal interface, generally older analog tape cameras use S terminal or av interface, and most digital cameras use 1394 interface for acquisition. The following two pictures are common acquisition cards and interfaces:

The specific acquisition method is as follows:

_ _. Connect the power adapter to the DCIN interface of the camera.

B. Connect the camera to a computer with a video capture card with the AV line /S terminal line or 1394 line.

C. use audio and video/canopus pro coder/adobe premiere pro and other software to set the acquisition parameters and collect the data on the tape. It should be noted that the data collected on the magnetic tape by the acquisition card is collected synchronously, that is, how long it takes to collect the data, which is cumbersome and time-consuming. This is one of the reasons why magnetic tape is gradually replaced by hard disk/flash.

D, according to the actual needs, edit and make the collected video by using audio/video/Canopus Pro Coder/Adobe Premiere Pro and other software.

The video captured by the camera is collected on the computer, and a video acquisition card needs to be installed. It is recommended to buy 1394 card to connect the motherboard. Such as a network card. There are expensive ones and cheap ones. You can choose according to your own purpose.

Card 1394 will be equipped with a simple editor and acquisition software to collect and edit videos. You can also use other editing and collecting software, such as pictures and picture series, premiere, and windows system also has its own mobile vendor to collect and edit videos.

Characteristics of tape camera

Tape camera is a kind of digital camera with magnetic tape as storage medium.

The biggest advantage and disadvantage of magnetic tape lies in its "linear" recording and playback characteristics.

1. The advantage of this function is that if there is a problem with a certain tape, the damaged signal is only the problem tape and will not affect the whole; The disadvantage is that playback can only be linear, and the speed of finding the specified playback point is not as fast as that of nonlinear recording on CD or hard disk, but it is inconvenient to "fast forward" or "rewind".

2. Compared with hard disk and flash memory, the disadvantages of tape are obvious. For example, magnetic tape is more sensitive to temperature, humidity, magnetic field, dust, etc. In addition, for cameras, the recording and playback of tapes need to rely on more complex mechanical systems and roller components, so there are many links, which are prone to problems and make the tapes more "delicate" during use and storage.

I want to convert the analog signal of the old camera into digital format

The analog signal of the old camera is converted into digital format, which is the process of compressing the video on the video tape and collecting it on the computer. Acquisition card with A/V interface or S terminal interface and acquisition and editing software such as audio/video/Canopus Pro Coder/Adobe Premiere Pro are required. The steps are as follows:

A, installing an acquisition card and acquisition editing software on a computer

B. Connect the power adapter to the DCIN interface of the camera, put the tape to be collected into the camera cassette, turn on the power switch, put the camera in the VCR state, and rewind the tape to the end.

C. connect to the computer with an acquisition card with additional A/V line or S terminal line.

D. Set the collection parameters and collect the data on the tape by using software such as Audio and Video/Canopus Pro Coder/Adobe Premiere Pro.

Collecting the data on the tape with the acquisition card is synchronous collection, that is, how long it takes to collect the data.

E. according to the actual needs, edit and make the collected video with audio/video/canopus pro coder/adobe premiere pro and other software.

After editing, you can save or burn VCD/DVD discs.

How to transfer the contents of old-fashioned video tapes to computers?

First of all, you must have a video recorder that can play this kind of video tape. Of course, the tape can be played. Secondly, you have to buy a 1394 card with PCI socket (cheap), and it takes about 30 minutes to get to 50 yuan. Correct installation of 1394 card (1394 acquisition card for desktop is inserted into PCI slot of computer motherboard, and 1394 acquisition card for notebook is inserted into PCMCIA slot of notebook), acquisition software and equipment connection (connecting computer with video recorder and video camera with 1394 cable) for video acquisition. It is best that you have or only have one camera (some cameras have USB output directly ...), then play the image from the video recorder and follow the interface prompts of the acquisition software! Can be collected into the clearest original AVI data, and then carved and saved. If you want to play it on a DVD player in the future, you need to use VCD format. In fact, it is not recommended to save the CD-ROM, because the data stored in the CD-ROM is affected by the CD-ROM drive, and it may be difficult to find the CD-ROM drive in a few years. Buy a mobile hard disk or a combination of hard disk and hard disk bracket directly. I just saved a lot of photos and lossless music with three 4T hard drives. Although the life of hard disks is not as long as that of optical disks, these hard disks are usually kept properly without connecting to a computer, and their life will be greatly increased.
