The background noise commonly has to be eradicated when mixing and recording sound effects or several other design elements for the video.įortunately, there are some methods that can be used to get rid of this background noise. In most cases, recording high-quality audio during shooting is difficult since the dialog is commonly hard to hear or competing with the background hums from the environment, for instance, a dreaded air conditioner or fans. > 20 kHz (-3dB).The most common request that you can receive from video producers is to remove the annoying noise such as rumble or hum from a finished piece of video, no matter if it is a corporate piece, a short film, a short commercial, or more. The audio frequency response of the grabber is 40 Hz. The USB Video Grabber digitizes audio signals in stereo at 44.1 kHz and 16 bit resolution. Using the USB video grabber makes no sense if you want to grab high-resolution analog material. The resolution of current analog TV broadcasts is not achieved by the USB video grabber. SCART connectors you findĪt VHS players do not carry separate RGB signals. VHS players do not have RGB outputs, since a composite signal is sufficient to provide theįull resolution of the recorded VHS signals. This is not anĮffect of the grabber, it results from the specifications Transferred to TV via separate RGB signals (SCART). The resolution of the composite input is sufficient to grab VHS videos without loss of sharpness.Ī picture from DVD is sharper when recorded via the S-video input compared to the composite input.īut also S-video does not give the full sharpness of a DVD image that is Is important to know when scaling down the grabbed video. Therefore the real resolution never reaches the number of lines that are transferred(550 lines). AnĪdditional blurr in television arises because the lines partially overlap on screen. Significantly lower than that used for analogue TV signals. This limit is due to theĪmong other things, this results from the fact that the video bandwidth of 3 MHz of VHS is With VHS videos already 512 × 384 pixels satisfy the required visual resolution.Īll details of a VCR image will be proper reproduced (I tested this viaĬomposite input that was feed from a DVD). Use 720 pixels that are not square (pixel aspect ratio =? In width, or you have to tell your video encoder that it must To get back correct proportions, you need to enlarge to 768 pixels The Grabber captures with a resolution of 720 × 576, thus the image scales about 9% to small. S-Video, small loss of details of the fabric Composite from DVDĬomposite, blurred Composite from recorded VHSĬomposite from VHS, blurred, strong loss of details in skin and fabric,īelow are switching distortions of the video heads Move the mouse over the image descriptions to see how image quality changes! VHS tape and grabbed it from the recorded VHS tape.Īs the screenshot of the grabbed picture were compressed to 720 pixels, I have stretched them to 768 pixels. Real-world VHS tape I recorded the signal also from DVD to This is not a simulation, I actually recorded You can compare the capture results of the composite and S-video input with aĭigital DVD test image. The grabber adds no visible noise to the picture. Reduced sharpness because it uses only composite signals. Input signals can be composite (from VHS recorder) or S-Video. The video grabber captures a full PAL image without border losses with 720×576 pixels. What can this grabber do in detail? Image Stereo Separation (1 kHz, 200 Hz high pass)įor grabbing videos from VCR (VHS) these technical parameters are absolutely sufficient. No video visible during fast forward of VHS tape (Preview) (Subsequent deinterlacing necessary, otherwise strong comb artifacts visible in fast moving picture parts) Good image quality for VHS videos, absolutely sufficientĪdequate sound quality for normal VHS tapes and VHS copiesĬaptures only with 25 fps or 30 fps and throws together two frames without deinterlacing. In Part 2 you get a tutorial for grabbing with the EasyGrabber. Since help was not available at the internet I wrote this test report. Many buyers have trouble grabbing videos with the EasyGrabber.
