Convert NTSC video to PAL without the shuttering

Most video caputured these days on DSLRs or HD/ 4k video cameras is 24p (which is 23.976fps).

If you make a PAL video from this, generally it will be very gittery and horrible.

So how to fix it:
take it into premiere and Right click on the clip and select Modify > Interpret Footage... and set it for the correct frame rate (25fps). Then create a comp by dragging the footage to the new comp button (see left)  (25fps comp)

You will then notice the footage sounds a bit chipmonk like.... to fix that, you need to fix the pitch.  You can do that in premiere, but I found that to make horrible quality sound.  The export the audio from this file.  (the high pitch audio).  And in Audacity, change the pitch by exactly this: -4.2709376042709 % (you just want to change the pitch, not speed it up as it is already sped up).


  

Then re-render your vid with H264, and all is good.

There will be a 4% increase in speed, but with the pitch fixed, no one will know the difference but you.  Most movies you will find are done using this method when converted to BluRay or DVD in Australia.

that is all.
