SD DVD Compression Tips- Please
on Jun 17, 2010 at 6:19:31 pm

Ok guys here the deal. I have never output to a dvd before and I have a dilemma on compression for a dvd. When I output directly from the timeline in final cut studio I go to export quicktime movie at the top it outputs my movie in amazing quality. It is also 25 gb. I export that same timeline for dvd in compressor even on high settings the quality is less than fantastic. The Video was shot on:
Panasonic AG-HPX300 HD Camera and
Two Panasonic AW-HE100 Remote HD Camera

It all ran through a live switcher and and then captured via a capture card in the Mac pro.
So its not like its crappy.

The total length that I need to fit on a dvd is about 1 hour and half.

Are there any good compression tips to make it look like that wow factor from hollywood for quality. Cuz right now on high its looks bad and its jaggy and fuzzy and looks awful on a television. How can I fix this I need a lot of help Please??????

Thanks

The source is?
1080i or p (what frame rate), 720p (what frame rate).
Some people find that 720 downconverts look much better than 1080 downconverts.
It seems the fine detail of 1080 can result in issues such as line twitter amongst other things.
That would mean the issue is the quality of the scaling.

It's hard to interpret "less than fantastic" into anything that can be trouble shot.

Its 1080i buts its going to be down coverted to an SD resolution for an SD dvd. I assume the original framerate is 60i since they are broadcast cameras although I would have to check for certainty.

Instead of going straight to MPEG2 Elementary stream try doing it in two steps.
In Compressor.
First step is downcovert to SD using a high quality codec such as ProRes.
You may want to set Resize Filter to Best but that will add considerable time to the encode so you might do a first test with Better and see if you're happy with the results.
If you are happy with the downconvert use that as source to create MPEG2 Elementary stream.

I'm sorry I'm stupid in this area. Could you go through the steps on exactly how I would go about down converting into pro ress and then what I do after that? If its not too much trouble. I kinda get half of what your saying.
