poor MPEG2 playback
I’m having trouble viewing MPEG2 files exported from Final Cut 6. The files play back OK in FC (and also once burned to DVD and viewed with DVD player) but look poor on Quicktime, VLC and Mpegstreamclip. The picture below will give you an idea. This is the same exported file played through quicktime on the left and Final Cut on the right.
The file displayed in picture below is:
Captured HDV 1080i50
Edited in native HDV
Exported Quick Time Movie, Current settings, Make movie self containedSame problem happens when I export using compressor “DVD best” settings.
Is this an issue with interlacing or do these players struggle with HD footage?
If anyone knows a “best result” workflow for HDV 1080i50, I’d love to read about it (interested in both SD DVD and also HD file for playback on computer)
Thanks heaps.

Hi Josh,
If here are interlacing problems can only be detected with an interlaced monitor or TV.
No one of the options you mentioned will work.
Toast a DVD and watch it in a historic TV set.

I think I found the problem. In my settings, under the “field dominance” section, the default setting for 1080i HDV was “upper” (Don’t know why this is the case). I changed it to “none” and this improved the quality of the file when played in quicktime. Still curious as to why the problem was only seen when played by quicktime and not when authored to DVD or viewed in Final Cut. Probably makes sense to someone who understands interlacing better than me (I don’t even know what field dominance is).

Ah, my ignorance is showing up all too well. I read a website that explained what field dominance (order) is and it answered all my questions. For anyone else who is as inexperienced as me and is having problems with lines across their exported video I found this website very useful and easy to understand. https://neuron2.net/LVG/interlacing.html
Now all I need is broadcast monitor. Ha. Maybe next financial year. Until then I’ll just burn DVDs to check final product.
So I assume that the Final Cut Canvas window compensates for the computer monitor’s progressive scan when it plays the interlaced HDV footage? Do computer DVD player programs also do some kind of de-interlacing on the fly?
If I want to create video files for playback on a computer is there a preferred way of deinterlacing? I read that setting field dominance to “none” inside FCP is not very good way of doing it.
