Set aspect ratio after encoding better?
Hey guys,
I have a DVD which I want to encode. The picture aspect ratio is 1.66. The image size is 720x576. So I cropped the black bars (top 56 pixel and bottom 56 pixel). The end result would be 720x464 which are perfect numbers for mod 16 encoding. Now 720 / 464 isnt the correct 1.66 aspect ratio. So what I did was- I forced resolution with mkvmerge to 768x464 when muxing audio+video- which works great and is perfect 1.66 aspect ratio looks 1:1 as dvd AR. Is it better to set the aspect ratio when muxing, as I did or is there a better way to define the aspect ratio during encoding? Thanks for eventual help. |

It's better to already set the aspect ratio during the encode using x264's --sar parameter, because some players only rely on the bitstream information. Mkvmerge will automatically read and apply this information to the container level as well.
These would be the common values to choose from: |
