? clarification of v556 progressive vs interlaced

[halsboss]

Hi, with v556 - "[Change] DVD Authoring: If source stream is labelled "progressive", authoring will change it interlaced."

What does that really mean ? If I have a progressive source, I would have thought I'd need it left that way and flagged as such. :confused:

Progressive frames are OK, its the sequence header which must be not be flagged as progressive. If you click on Tools>Show Program Info, this is what you'll see if its progressive only:

Progressive: Progressive Only

The correct, and now updated value, is:

Progressive: Prog or Int

The only files that typicaly "Progressive Only" are 720p files which need to be recoded anyway to fit on a DVD. This case the user had created his own video which was almost DVD compliant, except for the flag setting.

Thanks. Well... I roll my own PAL 576p streams from a DV camera via avisynth and HC, which I'd like to edit/cut'n'mix with VRD without recoding as they already fit onto a DVD.

May I read into your elucidation that PAL 576p streams won't be re-coded by VRD and that only the stream header will be affected ? :)

But you can easily check by opening the file in VideoReDo and clicking on Tools>Show Program Info.

Great ! Thanks for a great product and for your ongoing development.

Very much looking forward to upcoming features (as you've mentioned over time in other threads).
