Ok great thanks.. all good info..

Remove pull down... is this restoring footage that has pull down applied to it... as the wording implies..?? eh 23.98p back to true 24P.. or is it applying pull down..???

My HDX900 although set to 24p will give 23.98... as with 30p.. will give 29.98 .. in 59.94 system mode..

Would I need to tick remove pull down shooting 24p or 30p.. ?

Thanks again

Dear Robin,

On most cameras, when recording 24p, or 23.98, or 23.96, extra, duplicated frames are added to create 59.94 or 60 PSF (Progressive Segmented Frames). This process is known as adding Pulldown.

When you check Pulldown Removal, we remove these duplicated frames prior to recording.

As far as I know, you would only check the Pulldown Removal box for 24p, 23.98, or 23.976 footage.

30p or 29.97p will not have duplicated frames, thus you do not need to check Pulldown Removal.

I welcome comments and corrections in case I have any of this wrong, or if anyone can explain this better.
