Hello Dave, thank you for your answer. I actually tried to make a custom preset. I choose MXF OP1a from the format settings and than I choose one of the various video codecs..
The first thing you notice is, that the input boxes for width and hight in pixels is grayed out. So each video-codec you can choose has predifined pixel dimensions. So the list shrinks to those codecs that default to 1440 x 1080. Than I choose one of them, i.e. XDCAMHD 25 PAL in the lower section of the basic video preferences is a pulldown for aspect ratio. But there is no choice. It defaults to HD anamorphotic 1080 (1,333) and that is the only option to choose. It can't be set to square pixels. There aren't any setting anywhere, where I could customize it to my needs.
The biggest problem you may have is in your image layout for 4x3. If you're taking advantage of the 16x9 aspect ratio, you'll probably need to rearrange things for the more horizontally-constrained 4x3 aspect ratio. |
Absolutely correct. Actually all trailers have been made in 16:9 and now my client says he also wants a 4:3 version and is set up why it takes so long and is so pricey - since I need to rearrange and even rerender 3D parts to make it fit in a 4:3 layout. I asked maybe twenty times (including grafics that explain the difference between square and anamorphotic pixels) if he is really sure that he does not want just another version of the trailers but with anamorphotic pixels compressed and the definate answer was, no, we only work with square pixels internally. (...)
I'am actually not really sure if there is a way at all to compress a 4:3 video file with HD dimensions within the MXF standard. I mined the web what I usually do when such questions arise but this seems so special, that I did not found anything. But I had hoped this forum would know.
