De-interlace Video improves the TV capture quality a lot
Posted: 24 Jan 2005 13:27
Dear All,
I use the Windows XP as the TV channel's streaming server.
My TV capture card is the ASKEY TView2000 with the BT878 chipset.
I am using VLC081 as the streaming server with MP4 video transcoder and 2048kbps bit rate.
I try to set the capture card's PAL output resolution to 640x480 or 768x576 to get a high quality picture output.
However, I found that the athlete's edge will have S type distortion when I stream the sports channel.
This S type distortion will disappear if I lower the vertical resolution to 288 (eg. 720x288).
However, the picture quality becomes lower since the resolution is lower.
Finally, I found that the default stream_out_transcode's video de-interlace function is disabled.
I enable the stream_out_transcode video de-interlace function.
And Every thing becomes very good, the athlete's motion and movement is perfect ! I can't see any S distortion at their edges any more.
VLC081's Stream_Out_Transcode Video_Deinterlace function is quite powerful !
