I can't explain the problem, but I can say that "Fit" or "100%" only change the way the media is displayed within Premiere. Nothing is actually changed with the media file itself. When less than 100%, the image is basically resized from the original, but only in the monitor window.
That is to be expected. You go from 1440x1080 to 720x480 resolution for DVD and play it on a HD TV, which has difficulty with SD material.
Preview is just that, preview. For reviewing your footage, use an external properly calibrated monitor/TV.
10 bits BlackMagic will not really help you unless you use chroma keys or color grading extensively and you need to invest in the BlackMagic card.
I know that nothing is changed in the media by changing the type of preview, but if I look at it at 100% I've got major "comb" look on all vertical lines, especially with movements. At 200% and 400% it becomes very "mosaic" like - a lot more than I am used to seeing in other image editing programs when I go to 200%. It looks more like the mosaic I'd see at 400 or 800% in irfanview, which makes me wonder if my original footage is being captured properly. And at 200% I don't see that comb like effect any more. At "fit" it looks as sharp and clear as I'd like the picture to look, but it isn't appreciably different in size than the 100% setting. Really weird. Is premiere doing some kind of smoothing or tossing out one of the frames to make it look better in the preview window at the "fit" setting?
I understand about quality loss from 1440x -->720x, but this looks more like a field order problem (?) combined with a quality loss closer to going to 320x240!
You are looking at interlaced material on a progressive monitor. Try on an interlaced monitor, not on your PC monitor.
HDV uses lower feild first. Try that.
"HDV uses lower feild first. Try that."
Are you so sure about that?
HDV is upper field first.
>Then exported by adobe media exporter to mpeg and created a dvd in Encore.
What settings did you use to export via AME?
Preset: NTSC Widescreen Medium Quality
And drag the Quality slider to 5 in the Video tab.
Author that in Encore and the the DVD looks great.
"but if I look at it at 100% I've got major "comb" look on all vertical lines, especially with movements. "
If your original footage is interlaced this is normal.
"Not terribly bad on a regular TV, but really gross on the widescreen HD TV of the producer. Exported back to the camera it doesn't look that bad. "
If it looks okay everywhere except the HDTV, well, maybe its the HDTV.
Actually, I just tried a few of the Presets and couldn't get a bad looking export unless I purposely tweaked the preset to look bad; e.g. set the quality slider all of the way to the left, which makes me ask again what settings you used in Adobe Media Encoder to export.
I can say that I have seen an HD TV do a poor job of displaying an SD DVD that was created with a DVD authoring tool. Sometimes creating a DVD is hit and miss. It took me 6 months of tweaking ProCoder to get settings that I liked when I was using that tool as a transcoder.
