To convert a videotape into a VCD, first, a signal source and a video recorder or camera that can play a videotape. Second, the video recording and compression process is to digitize the analog signal of the videotape, stored in a compressed format (MPG file format) to a computer. If you are using a video capture card, to convert the collected AVI format file to an MPG format file, you can convert the format after the collection is complete or convert the format after editing ); third, during the editing process, you can edit, add subtitles, and add special effects to the collected digital files, both files in AVI format and files in MPG format can be digitally edited. Step 4 is the burning process, that is, the edited files are burned to VCD through the recording software, and the last is the preparation of the album art, make a beautiful album art for the CD, even if the VCD is complete.
The conversion from a videotape to a VCD is the most basic way to make a VCD. If the content of the videotape is an edited program that does not need to be processed, compress the video's signal into the computer, directly perform the burn operation.
If the signal source is a digital signal, that is, the playback source is a digital camera or video recorder, a digital acquisition card is required for signal collection. Currently, the recording format of home digital cameras is DV. The resolution of DV Video Images reaches 500 lines, and the signal-to-noise ratio is 54db, which is close to the lower limit of the broadcast level, therefore, the DV format video signal is very good. To transmit digital signals in DV format to a computer, you need an ieee1394 digital acquisition card (some computer boards have already integrated 1394 cards, so you do not need to add another 1394 cards ), connect the DV in/out interface of the digital camera to the interface of the 1394 card, and use the digital acquisition software to collect the digital signal to the computer. Adobe Premiere 6.0 and Ulead mediastudio 6.0 now provide the ability to directly collect DV signals to computers.
