It is therefore probably an analogue TV card. Since there then primarily synonymous depends on how well the signal. The more noise in the Picture, the higher the bitrate you need to make it without noticeable Losses to compress.
Therefore s.besten before Compression subtly (!!!) noise. Unfortunately noise is a very high computation-intensive process. Not the noise rarely lasts longer than the subsequent Compression.
A workable compromise is to use the example with VirtualDub supplied filter and smoother temporal smoother. (For smoother would it is clearly better alternatives, but the need then halt the synonymous multiple computing time). For a moderately noisy analog cable signal is the following filter chain pretty good: First, the temporal smoother. Setting "3". Then the smoother. Rauschvorfilterung activate and set to "2".
Encoding with XviD will not. This can unfortunately not qualitätsbasiertes Encoding (or it is not for lay people without deep knowledge of the Procedure, adjustable). So prefer DivX, as is the one with Click selected. As a "quality value" is something between 3 useful and 4 (where lower values result in better quality, but in return, of course synonymous with larger files).
Another useful measure is in any case, even before the Capture the noise so as to curtail the black edges that completely disappear, which is not only somewhat smaller file sizes, but notably reduced computing synonymous, of course, especially when "letterboxed" material such as movies. And finally we should gecroppte Picture resize so that Height and Width both are multiples of 16. That makes it the filters and particularly synonymous with the encoder lighter, thus saving computing time again synonymous. In addition, it improves the compatibility. The fact forced resulting distortion of aspect ratio are usually so small, that they remain virtually unnoticeable.
The resulting file size strews but still enormous, even with material for which is always the same Resolutionergibt. It depends qualitätsbasiertem halt when encoding of the image content, such as large the file is. In the middle are used in the above settings to about 600. .1000 MByte / h quite usable material out.

DivX not forget to CPUs with more than one logical and / or real nuclear option, the "increased Multithreading" box.
