HIGH QUALITY TPU DVD Video Released from Jack Durban

[EMdevices]

but what did you mean when you said that Jack's video is already deinterlaced though?

I have something to compare it tooÃ,  (frame grabs posted long ago)Ã,  and those are more clear and the interlaced fields can easily be seen and when taken apart, the picture has way more info for use with Topaz labs, or other superesolution solutions.Ã,  Ã, But, if you look at a typical frame from the Jack video,Ã,  you won't see the typical lines on the edges of moving objects (mice teeth,etc..)Ã,  which are indicative of interlaced video,Ã,  instead you will see a blur,Ã,  which means he already DEINTERLACED by BLENDINGÃ,  the fields together.Ã,  Ã,  Ã, I'll try and post one of these "mice teeth"Ã,  frames so you can see.....

EM

P.S. Look at the tape measure in motion , see the lines?Ã,  Ã,  now compare to Jack's video.

A good comentary on deinterlacing etc..Ã,  www.100fps.com

In the frame shown,Ã,  the tpu itself is not moving, so we are ok, but in most of the other shots, either the camera shakes,Ã,  or Steven moves the tpu around,Ã,  so we loose so much info by Blending.Ã,  Ã, Ã,  Remember,Ã,  each field in a frame is an actual picture in time, so we get sharp motion frozen pictures of the tpuÃ,  (but at half the vertical resolution, but that's ok since we have 2 fields per frame and they're offset verticaly,)Ã,  just read the above link and it will explain it a lot better.

The botom line, we need the have as close a copy to the original as possible,Ã,  no deinterlacing, no nothing.Ã,  We can do the rest digitaly and extract all the info that can reasonably be extracted from both of the individual fields within a single frame.

Hi EM,
Jack?s video is still interlaced.

You are correct, that it might be more usefull to deinterlace
the video this way, that it will be converted into
single frames from the single fields and thus upconvert from
29.97 Hz to about 60 Hz,
so every field will be converted (interpolated) from 720x240 to 720x480
and the vertical 1 scanline difference will be adjusted.

This week, I don?t have much time, but when again having
more time I will see, if I can this way get more infos from it.

Yes that's correct Stefan,Ã,  let's give Jack some time, he did promise to do another copy like he posted.

And yes, you can say the footage is "interlaced",Ã,   a sharp picture can also be thought of as "interlaced",Ã,  the point was that when he copied from the master tape to the computer, he probably selected deinterlace on the fly by blending, or something simular.Ã,  Ã,  (my capture device has that feature as well)Ã,   So that's why the fields got blended and smeared where there is motionÃ,  (and there's lots of motion right where things get interesting and zoomed in on the TPUs)

Notice in the picture the position twist and relative postion of the bailing wire to the control coil turns.  Flux capacitors would have to be made out of something you can magnetize but in this case the Earth is magnetising this capacitor.

Ok,  to illustrate,  here's the two fields in the above frame,  deinterlaced and placed next to each other.  These can then be scaled up vertically, back to 480,  and since they are slightly verticaly shifted, virtualDub and other software can compensate and adjust.  Now we can scale up the time speed from 29.97 frames per second, to almost twice that (not too sure on this, as the frames are interposed, this science is a bit involved)

Anyway, notice that now you can see more detail in the moving objects  (tape measure in this case)   You might still get some bluring due to the motion and the shutter speed of the camera,  but it's nowere near as bad as blending the fields.

P.S.  I added the scaled up version.
