Reverse field dominance – two fields forward, one field back

[Michael Pfost] “There is a frame order setting “

You mean field order?

I doubt it’s these settings. I bet it’s from a botched reverse telecine. Is your pulldown consistent across the entire program? Even across graphics? I doubt it.

Well it is a telecine of a TV series from the 60’s delivered to me on NTSC DigiBeta.

From what I can tell it was done correctly just from viewing the progressive version (created by Compressor’s reverse telecine). I just added bars and tone at the beginning on the FCP timeline and saved as a Quicktime ProRes file (same format). But perhaps there are field issues that the eye cannot see?

The final ProRes PAL file looks spectacular, so it makes me think the the MXF conversion is botching it up.

Are you watching this on a video monitor?

Another thought, MXF is a wrapper so just like quicktime or AVI you can have one of several different codecs within it – what settings are you using for that?

[Michael Pfost]

I’m using IMX-50 video, BWF audio. The container is MXF Op1a.

I’m viewing the file through the output of my Matrox Mini box using component outputs. The monitor is LCD. Is it necessary to have a CRT monitor or can you view material on a flat-screen?

What is recommended for viewing interlaced material on a flat-screen? (That isn’t crazily priced?)

You can view on a flat screen. The combo of your matrox box and a proper monitor is fine.

Any chance you can post a second or two of the full resolution video? It would be much easier to see what you’re seeing.

Hi – should the view setting be 576p (in FCP) for the external monitor? Also, should I scrub through the timeline and show both fields, field-1 or field-2? Playback always looks smooth.

The resulting video says that it is TFF (and that is what I selected when rendering the final video in Compressor), which is what the network requires — but it sounds like even though you may have this set, internally, your fields can still be a mess?
