Hi

I have a video in 740x480 .mpg format (see attached). I am trying to recode in into .mp4 (h264). But when I do that sometimes the output format ratio is different. In this case 654x480. I traced this to ocassionaly when I drag a new video into premier pro the pixel ratio under sequence settings does not default to 1.0 but to something else in this case 0.9091 My question is should I reset this aspect ratio to 1.0 to force the new rendered video into the same dimensions 740x480 by reseting pixel aspect ratio from 0.9091 to 1.0 or should I leave the pixel aspet ratio as is and let the frame dimensions change from 740x480 to 654x480? Which is the right solution to maintian the origional video quality and integrity?

I believe your sequence or export needs to be 720x534 par 1.0 and progressive.

Also, in Output where it says Lower, you don't usually want that for an .mp4 as it refers to Lower Field First which means Interlaced video and for computer or device playback you want Progressive video. So manually set Fields to Progressive/None option to create deinterlaced output.

Thanks

They're the same, but the 720x480 has non-square pixels (the .9091 number) and the 654x480 has square pixels (1.0). For computers and HDTVs, stick with square pixels.
