Field utility

[Mosaic]

Are there any utilities to take a Video frame (bmp,tga,tif)....and show me the fields as separate images?

By using DVD2avi (RGB mode) u can make an uncompressed avi ...Premiere will use that to make an image stream....which u can pull up in any gfx sware and look at in detail.
Great for checking color differnce and encoder artifacts. But no good for telling which field is which to be sure of field ordering.

use avisynth and you can separate the fields and make a 50/59.97 fps half height avi file. when you play it back, you can tell if the field order is wrong and just use swap fields avisynth command.

Enf...

any guide for that?

But I need a guide as well.. I am no avisynth expert.

Assuming you've installed avisynth. Start note pad and type:

loadplugin("C:\mpeg2dec.dll") #get the dll from doom's
mpeg2source("C:\project.d2v") #assuming you've made a project from a dvd
assumeframebased.seperatefields

Now if you got an avi (and not a project by dvd2avi from a dvd movie) exchange the two first rows in the script for

Avisource("C:\project.avi") OR ...
Directshowsource("C:\project.avi") #for type-1 avi

Save as project.avs and drag it into TmpgEnc. Choose file->output to sequence.

I can't tell how the fileds are going to be separated by this operation.....

I would like to understand....

[ulfschack]

ok, maybe you should read again :)

How 'bout separatefields?

Or is it so that you don't understand the entire concept of an avisynth script? In that case I'll try and help you. But for starters you should look at the Avisynth doc (http://www.videotools.net/uk/index.php) (you'll have to clik on the link of the top of the page)

Did you or did you not run it trough dvd2avi (hence the file "project.d2v")? What is your source?

Tell us a little more

cheers
