Interlacing-Artefakte bei Umwandlung 4:3 -> 16:9

Interlacing artifacts when converting 4:3 -> 16:9



Frage von derchiller:
Mai 2008

Hi! I would like HDV material of my FX1 with DV material of my old camera mix. I must first of this course bring to 16:9. I've done by saying the material in MSP 8 as AVI and spent it in 'Cropping' above and below each have 72 lines omitted. Then I 'Keep original size' is activated and under 'General' 16:9 elected. Size and proportions vote then, the problem is that the result is very ugly artifacts when moving objects aufweist, which probably comes from the interlacing. Do you have a tip on how to avoid it?



Antwort von B.DeKid:

Can we not just put black bars over it, instead of cropping?
In 720x576 format you want it to have?



Antwort von derchiller:

Yes, 720x576. With black bars, I tried it synonymous, because the camera just so synonymous top and bottom black bars inserted, if I record directly to 16:9. These are later in MSP no longer be seen, the picture is 16:9 and not distorted.

But if I with the camera in normal 4:3 record and the black bars in MSP insert later, sees the matter differently: I get a 16:9 picture, but in which the black bars are still visible, ie the real video In the Width withdrawn.

The black bars, the camera produces are apparently of the software is not detected and displayed, while the subsequently inserted bars as part of the video will be handled. I hope I have the problem described reasonably understandable.

EDIT: I just noticed that the camera in 16:9 mode, but not simply insert black bars, if it is synonymous in the display looks. In reality, the material is anamorphic stored on the tape and a 16:9 flag. I'd probably prefer the 16:9 mode will ...

When an interlaced video to be scaled, it must first undergone a deinterlaces undergo.

Here are a few basics and examples about this:

Yes?

As a general rule is that so. Exceptions prove the rule, however, you'll want to secure themselves.

It is synonymous to resize fields separately and then together ... Disadvantage is that you s.statischen picture backgrounds, etc. gets a podium.



Antwort von asbach63:

Hello, thank you for your answers. With deinterlace it synonymous, I have tried (with VirtualDub), the artifacts will no longer appear to favor the sharpness suffers a bit ...

I need from the DV material but anyway just a few short excerpts, and quick movements are seldom synonymous, so it is perhaps as synonymous.

How should I proceed because to resize fields individually?
