Interlacing two videos for 3d viewing...help needed

JaggerWolf · Post by **JaggerWolf** » Wed Feb 27, 2008 4:42 pm

Ok I have searched all over the place and just can't find answers to what seems like a simple idea.

I have a dual digital 8 cam setup, I can record two separate videos for use in making 3d videos. We have effectively made the red/blue 3d movies using this setup. What I would like to do now is make field sequential video for use with a shutter glass 3d system.

It seems all I would need to do is deinterlace each cameras footage into right and left files and then reinterlace cameras ones right field with camera twos left field.

Any help on this would be great, I am currently using video studio 11.

Fields come in Upper and Lower not Left and Right.
When a Cathode Ray Tube Television (CRT) produces a picture it paints half the screen first and then the other half second. It does so by painting every other horizontal line. In the UK there are 625 lines per screen - (Standard definition) - High definition contains even more.

You cannot (at least with this software) mix two video sources taking a frame from video 1, then a frame from video 2, then a frame from video 1 etc.

The only thing you could try which probably will not work anyway is to superimpose the one video on top of the other using an overlay track and then adjusting the transparancy levels.

Ok I understand the upper and lower fields - What I meant was the right camera footage would be on even lines, and the left camera footage would be on the odd lines. That is how field sequential 3d movies are produced.

I have been told by several people that its simply a matter of "deinterlacing" each video into two separate videos <upper field & Lower field> Then reinterlacing the upper field from video A with the lower field of video B.

I know it can be done through a special circuit board or hardware but it seems like there should be some way to do it through software.

Possibly with more expensive software but not with VideoStudio.
Sorry.

The theory os really easy, the practise..... erm, I don't know of any software off the top of my head that will allow you to do it.

There is a program at does this called "StereoMovie Maker" its freeware but the quality of the finished video isn't that great, i'm trying to achieve the same effect but with better full quality.

Digital Juice is having a sale for a third-party software called Magic Bullet that sounds like it can do de-interlacing. Problem is, it doesn't look like it works with VS, as it is a pro app, at a pro price
