Im new to this forum and HD editing. Ive downloaded the trial version of Adobe Premiere CS5, my camera is a Panasonic HDC-SDT750, ive filmed in 1080p 50i. When I import the footage it looks great in the timeline then when I export to H.264 it took 3 hrs to make a 4 min video then the footage in the new file ,the colours were discoloured in places. Can anyone give my any advice or tell me where im going wrong please. My computer has a dual core processor with 4gb ram.
