I need video help! - Deinterlacing?

I need video help! - Deinterlacing Can anyone explain to me an easy way to deinterlace a video without losing quality? I've tried two different programs and they both totally ruined the quality!

Any help is appreciated, thank you! :) Asked by chasegran 30 months ago Similar questions: video help Deinterlacing Entertainment.

Here's some advice about Deinterlacing. When is it harmful to deinterlace? When is it better to leave a picture interlaced?

When is deinterlacing bad?1) Maybe it sounds stupid, but if you deinterlace a video which is not interlaced, then the result is worse than the source of course. This sounds trivial, but consider the following: * Some TV channels can air movies in a non-interlaced (=progressive) state while airing the commercial breaks interlaced. * TV channels can air a music video clip interlaced and the next one non-interlaced.

The same applies to commercials: One commercial is 25fps, the next one is 50fps. * TV channels can air the news interlaced, but the intro to the news (spinning globes etc) is not interlaced. * The professional coverage of the 11th September attacks by the Saudi Arabian terrorists on the World Trade Center is aired progressively but the amateur footage of the events is aired 50fps.

* Vice versa a coverage may be 50fps, but changes to 25fps when old footage (e.g. World War 2 films with * A program may be 25fps, but the ending credits are 50fps. * A program may be 25fps, but a change from one scene to another may be interlaced (see below). * A single frame can even consist of progressive parts and interlaced parts (see below).

* Some channels air 352x288 which is always non-interlaced (because heights below 300 pixels cannot be interlaced as defined by international committees). There are some TV channels that air (nearly) always interlaced (like MTV) and some that switch between progressive mode/interlaced mode from one program to the other or within one program without any rule (Futurama is aired progressive, the following Simpsons is aired interlaced). Thus this can give you some problems if you deinterlace everything automatically or leave everything progressive.

This is a typical capture from the European Channel MTV Central via digital satellite. As you can see it's interlaced and has to be deinterlaced. He same music clip, the same scene, but different TV channel (Belgium channel 'Zik).

Not interlaced, thus doesn't need to be deinterlaced. You'd lose quality if you deinterlaced it, though the quality loss wouldn't be high (see below), because the deinterlacing methods described on this site are quite good. Please also note, that after you deinterlaced MTV's footage (even with the method 4b) = Hybrid Method), the result is worse than this progressive footage from 'Zik.

Side note: The next video music clip after this one, was interlaced again. Sources: http://www.100fps.com/video_resolution_vs_fluidity.htm .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
