If you want it to fit downsize to 54% for PAL.
Hello and thank-you,
this is a multi-cam shoot and 1 camera was set to HD and the other 2 SD
Create a NEW Sequence set to the Format required then Copy & Paste the HD sequence into the New Sequence. Make sure you "RMC" and check the "Scale to Frame Size" button is turned ON. If you have Titles on a different Timeline you may need to select it and repeat aswell. "RMC" Right Mouse Click!
check the "Scale to Frame Size" button is turned ON
That would create the unwanted black bars. Ann's method will not.
