Have two sources. How to "mix" them to one source

[axolotls]

Hope this is the right forum

I have two captures of the same scenes but at different angles.

I would like to know, which program can sync the two source together and allow me to A-B between the sources.

I have VS7 and tried the overlay function, but it is clumsy.

TIA

You can do it in AVIsynth.

Bring in the two sources, each with a different variable name, then display both side by side. You can experiment with the trim command to get them synched properly.

Then view the video and make notes writing down frame numbers where you want to make the switch between scenes. Then it's a simple function to swap one for the other source over a range of frames.

m1=avisource("angle1.avi").trim(5,0)
m2=avisource("angle2.avi")

movie=m1

#replace frames 1002-1536 with same frames from m2
movie=(movie,m2,1002,1536)
return(movie)

function scene(clip a1, clip a2, f1, f2)
{
   # a1=main movie, a2=angle2
   segment=a2.trim(f1,f2)
   return(a1.trim(0,f1-1) + segment + a1.trim(f2+1,0))
}

You could even play around with the desolve command.

Another method: Slow fading into the next scene (dissolving)

m1=avisource("angle1.avi")
m2=avisource("angle2.avi") 

movie=m1

#dissolves to angle2 at frame 1002 and cuts back to angle1 at frame 1536
movie=angle(movie,m2,1002,60) 
movie=angle(movie,m1,1536,0)
return(movie) 

function angle(clip a1, clip a2, f, d) 
{ 
   # a1=main movie, a2=angle2, d=number of frames for dissolve
   # make sure d is not too high
   return(dissolve(a1.trim(0,f+d), a2.trim(f,0), d)) 
}

This one just changes to the new angle. To change back, you need to execute the function again. Code can also be used for hard cuts if you set d to 0.

you can also use Vegas - put one video on one track, the other on another, adjust the track motion so you can see both in the preview window, and make your markers for edits...

Thanks Daryl!! I didn't know Avisynth was that powerful. I will use your tips/scripts as a fallback if I can't find something a bit "easier" (no offense).

Housepig: I'll try Vegas if there is a trial out there.

I also downloaded the 30 day version of Premiere and have the tracks synched, but still unsure how to transition between Video 1 and Video 2.

Thanks!!!!!!!!!!!!!
