Update: Downloaded the Trial version of Avid and gave it a whirl today.
Opened the PAL (720×567) footage in a 25i project and then imported the PAL bin into an NTSC 24p project then exported with dimensions 720×486.
Is that the correct setup for NTSC or is there another method of setting up the NTSC project so that it plays at 29.97fps.
Do you mind posting an insight of your project specs? I suppose it generally comes down to what is requested by client.
Cheers
