Hi, im new in this community, i really need help, i recently started my career in video production, i really like this "world", but, as a beginner, i have some issues about ir. For example, i have to export a video in Sd for broadcast, i have a big doubt, because my footage is in HD (froma a Xd Cam, Sony PMW- Ex3), and i have to downconvert it to Sd by add the HD secuence to the SD(4:3), but my cuestion is if the final video would have a problem with the Pixel Aspect Ratio?, because the square pixel of the Hd and the non-square pixel of the sd, and im afraid that the video will look distort or someting like that. Im afraid because one of the requirement of the Tv station , is that the video shouldnt have to be distortionated, and im afraid it will.Or i dont have to worry. Specially because the video is 16:9 with square pixel to 4:3 non-square pixel.
Really i need help, because is a Big client that we have, and if a do a bad job, maybe we will lost it and our company will not grow.
