Hi,

I have two separate video files, which I'd like to combine in one interlaced video. What I mean by one interlaced video is that it's odd lines would display footage from video A and even lines will display footagre from video B. I tried to google on how to achieve something like this but with no result. Im a complete beginner to the video editing so any help is appreciated. Im not even sure if I should use Premiere Pro or After Effect.

If you are asking how to create a true interlaced file, with each frame consisting of one unique upper and one unique lower field that combine to make the frame - you can do that by:

Edit your master timeline at 59.94 progressive. In your case, I guess you would create the timeline, place one video on it, then manually go through and replace every other frame with the second video.

When done, export the timeline from Premiere as 29.97 interlaced, upper field first (dominant).

This will create a true interlaced file, in which frame 1 upper field = frame one of the 59.94p timeline, frame 1 lower field = frame 2 of the 59.94p timeline, etc, etc.

If you import this exported file back into Premiere, you can verify it is correct by placing it on interlaced timeline and parking the playhead on any frame. If you click on the wrench in the Program monitor, you can toggle between displaying the first field or the second, and when you do - you will see two different images without moving the playhead.

However - be advised that an interlaced video will only display properly on an interlaced TV - not on a computer monitor.

if premiere had a strobe effect, you could automate this. or expression on opacity. I only know AE is probably better suited for scripting/expressions.

i know you can do this in AE, put both into a double their fps comp. use strobe effect 1/fps duration so that the top shines through every other frame. then nest that into a half fps comp again. it will turn every 2 frames into 1 frame,2 fields. render out as interlaced. I don't know how you'd do it in premiere.

Sounds easy to pull off if you are just talking about interleaving the images and not dealing with fields (old TV tech).

Just create a image with one pixel line of black and then a line of white across the whole screen. Put the two images into one comp. Use the black and white images as a luma matte for your top layer, letting your bottom layer show through between the lines of the top layer.

Hope this helps.
