how to solve 'shaking'' image

[wijnstra]

Hi,

I'm using an ATI 9800 AIW card to capture analog video, and I'm using Pinnacle Studio to make DVDs. I would like to capture the analog video in DV format, as this is compressed but still high enough quality to edit it.
- When I use Pinnacle Studio to capture DV, it seems as if the vertical resolution is not as specified, but possible half for some reason. So, this is no option for capturing.
- As an alternative, I am using VirtualDub for capturing. For some reason I cannot select the DV codec for direct capturing. When I capture the video uncompressed, everything works fine and I can make a DVD with Studio. The disadvantage is the large size of the video file (about 1Gb per minute). So, I have used VirtualDub to convert the uncompressed video into DV format (now it is possible to select the DV codec). But when I use this file as input for Studio, the resulting video is shaking, as if each pair of images are swapped.

Does anyone know how to solve this shaking problem? Thanks!
(The strange thing is that when I record the uncompressed file in VirtualDub with the option 'swap fields', and convert it into DV, then the result of Studio is better, but the shaking is not completely removed).

Inverse telecine?
Try using Windows Movie Maker to capture, directly into DV-AVI.

Swap fields in VirtualDub is a workaround for a very specific problem of some old Matrox capture cards. It is not a field order switcher.

When you say the image is shaking do you mean after burning to a DVD it's shaking on TV? If so, you probably just have a field order issue. Either Studio assumed the wrong field order for your DV file or it produced an MPEG file with the wrong field order. DV is normally bottom-field-first, MPEG top-field-first. I don't know what happens when you capture analog video an ATI card and convert to DV -- it may have made a top-field-first DV file.

When I use Windows Movie Maker to capture from an analog input device, the DV-AVI option is grey-ed out.

Indeed, the final MPEG that I see on the TV shakes. I also thought that it had to do something with the field order. The uncompressed file that I obtain from VirtualDub is probably correct, since it is correctly converted by Pinnacle Studio into MGEP on the DVD (no shaking). When I use VirtualDub to convert the uncompressed file into DV format (with the Panasonic DV codec) then the field order is probably wrong (since the MPEG file based on that DV has the shaking artefact). The question that I have is how I can change this field order again.

(BTW does anyone know why I cannot directly record into DV format with VirtualDub, but VirtualDub allows to convert the file into DV format later on?)

Have you got a DV encoder codec installed?
Lots of software comes with a DEcoder, but not the encoder.
Panasonic DV codec is free.
