I have some footage I'm editing that's 16:9 and trying to produce an MP4 with a 720x576 resolution. The produced video though is created as having a 0.002 AR rather than 16:9 which obviously displays as a very thin vertical line. For now I've just set VLC to force a 16:9 AR on playback but I'm wondering why this is or what my options are?
This is no doubt a stupid question to those who know a lot about video editing but I'm afraid I don't, it's only a bit of a hobby. I suspect the answer will be because 720x576 isn't a 16:9 format but then I've seen others who say it can be so I'm not sure? I've seen people say to use 1024x576 but that's not a supported option?
If not what's my best option to produce a video which has a source AR of 16:9 but in a Standard Def resolution? Would I have to just encode it as 720p but use a lower bitrate or something?
I'm using PowerDirector Ultra version 16.0.2816.0
Below shows output from MediaInfo if of use:
Width : 720 pixels
Height : 576 pixels
Display aspect ratio : 0.002
Original display aspect rat : 16:9
Thanks for any help or advice you could give me!
