  What happens to ‘progressive’ when I export to a lossy/losless format

  Posted by Allard Depallerd on March 16, 2011 at 12:40 pm

  When I export my footage (progressive 1920×1080 30p) to a quicktime movie… with a lossless/lossy codec (eg Photo Jpeg or Animation), the output file doesnt seem to be progressive or interlaced anymore.. (when I read it with mediainfo)..

  why is this?

  thanks!

  Well, the file HAS to be either progressive or interlaced.. it can’t just be neither. I’m guessing that Mediainfo can’t identify the interlacing or lack thereof from the metadata of those file formats. Nothing to worry about, I’m sure. If you chose progressive in the Export dialogue, it’s still progressive.

  Also, “lossy/lossless” doesn’t make sense.. it’s either one or the other. Photo Jpeg is lossy, while Animation can be lossless (with quality set to 100%) or lossy (at lower quality settings), which makes it quite handy.

  I put the export settings on progressive when I exported the Quicktime files. But like I said.. neither an export with a lossless or lossy codec (I tried both, that’s what I meant by lossy/lossless) gave me a progressive ‘label’ in mediainfo..

  So basically…you are saying that if I exported the file as progressive or interlaced.. the output file is still that.. I just doesnt show up in MediaInfo because that program cant handle that file format very well.. That’s good to know, because I thought maybe files would ‘loose’ their progressive/interlaced status as soon as you encode them to a lossless or lossy format. Thank you for clearing that up.

  Would you know a fileinfo programme (like Mediainfo) that would be able to detect this properly? thank you for your explanation (and pardon my bad English).
