Batch Deinterlace

[joshbm]

Is there a DOS program, or any program that you can deinterlace multiple pictures (from a video-interlaced source) at once? That also allows you to blend both even and odd fields together?

PS- I have Paint Shop Pro 7, but I don't know if you can batch deinterlace.

Thanks!

You can use TMPGEnc to do that.
It's simple. Open the Video, chooose the Deinterlacing-Methode you prefer, choose the Picture-Range you want and use File -> Output to file -> Sequence BMP/PPA...

Thanks Kika for your reply, except that's not quite what I was looking for... maybe I should have explained it better. Well I have about 5 hours worth of video and I went through them all and took snapshots. I DID NOT have on the deinterlace filter while taking snapshots.

700 snapshots later and I don't really want to do them all over again except it would be nice to just have a batch program do it all for you. Or better yet have a program that asks if you want to:

Blend Both Together
Keep Odd
Keep Even

For each file (without me having to manually deinterlace and blend them in PSP-- think about doing that for 700 pictures!).

Some standalone JPG/BMP deinterlacers can be found on http://neuron2.net/mine.html

OK, now i understand what you mean.

But the Answer is the same: TMPGEnc.
If the Files are named the righ way (pic001.bmp - pic700.bmp as an example), TMPGEnc can import them as an Image sequence.
Then use the Filter you want and export the Pics as an Image sequence.

If the Pics are not named this way, you can use ACDSee for renaming them. But the Pics has to have the same size.

@Wilbert
Geez, guees your way is not a bad one... :)

Thanks guys for your reply. I will look into TMPGEnc. I just looked into the stand-alone deinterlacers. Those are nice :-). Except it would be really good if Donald Graft added support for taking the odd and even frame in the picture and blending them together (A+.5B --> .5 as in transparency).

Also does anyone know the script in AVISynth for:

1.) Extract even field
2.) Extract odd field
3.) Sharpen odd field
4.) Take odds field and apply 50% transparency
5.) Overlay odd field on even field (with 50% transparency)

?

Thanks

cilp = original clip

1.) Extract even field

clip1 = clip.selecteven

2.) Extract odd field

clip2 = clip.selectodd

3.) Sharpen odd field

clip3 = clip2.Msharpen # look up the correct arguments/parameters

4.) Take odds field and apply 50% transparency

cilp4 = clip3.ConvertToRGB32.Mask(...)

5.) Overlay odd field on even field (with 50% transparency)

final = clip1.Layer(clip4, "add" ...) # with threshold of 128

If you have more AviSynth related questions, I suggest you post them in their forum.

Thanks,

I don't think I will have any more problems. All I have to say is Paint Shop Pro 8 is really nice. Apply all the effects on 1 image you need and it will automatically do the 700 :-).

Thanks all for replying,
