shutter speed vs frame rate vs dvd quality
Hello,
I have been working on this problem for years with poor results.
I have good looking video off the timeline to monitor, in compressor’s preview ,in studio pro’s simulation. But my video’s suck. I have treated it as a compression and or FCP problem in the past with lots of advice and no results. I am using a canon xh a1 1080i, 30f, shutter at 1/30…
Capturung with PRORES 422./to FCP/to Self contained QT Movie to compressor to studio pro.THIS IS MY QUESTION ??? Is it possible? That with too low a shutter speed(or other camera adjustments) would cause my video to look good everywhere along the line until final output.. which is playback on DVD. DVD is aften blurry jaggy etc..

Nope. If footage looks nice on control monitor w/ this shutter speed it should be okey down the line. I don’t like your workflow because it’s a little bit redundant. I’d go this way: capture in ProRes for editing in FCP. Then send to Compressor to down convert into MPEG-2 SD w/ meta data included and AC3 sound stream. Then import both stream as assets into DVD Studio and build DVD. This way you convert your material only twice – when ingested and converted in Compressor. BTW, IMHO, it’s peculiar shutter speed.

George,
Your problem is not about post-production, but shooting.
You say that you are using 1/30, how do you expect your picture not being “muddy and blurry”?
You must have good reasons to shoot with something different than the native (1/60).About your workflow, why don’t you start by getting a good HD/QT master before thinking to make a DVD?
Yes, you make a perfect Prores HD master, then when you are happy with that HD master, you downscale that and make a perfect SD Prores master,
When you are happy with your SD master, you bring that to an application that compress an MPEG-2.

George, the others have covered things well but I thought I`d put in a few comments of my own, guesses or otherwise.
Why are you de- interlacing a 30 frames per second (60 fields) interlace camera feed? Either leave the video in this original form or graduate to a camera that can give you 60 frames per second so you can make (both) 60 frames, fields non- interlaced, or 30 frames, 60 fields low noise as whichever your market needs. Of course, this allows you to turn off “de- interlace filter fast …. line averaging” (or any version of this) and it`s always resultant trash.
I see, antialias setting- 100, detail level setting- 100, and automatic gamma correction- on, at the same time. Likely, it`s a good idea to always run, 0 and 0, and be experimental on the gamma corrector as follows: If the scene doesn`t matter, like you`re just importing titles leave it on. For most other stuff see if maybe pushing slightly more light in with the settings, 0, 0, off, then rendering for better gamma in Photoshop software should give quite a leap over what Canon provides. In the same area of quality and cause, is your camera using auto iris and auto focus? See if your model will handle manual lenses, preferrably with prime (that`s usually 3- element Cooke) lenses next to the zoom.
Spatial and temporal quality adjustments, just be experimental but note:
My recent experience with Canon comes not from a video camera but from a photographic scanner. I would put my friend`s positive picture in the camera and start adjusting on the computer then hit print. The moment I hit print, the Canon software would turn all my gamma and a few other adjustments grey, and output an unusable picture to the Hewlett Packard color printer. If you are using any Canon software for the camera next to your (Apple Final Cut?) software, next try see if you can do without it installed at all.A ProRes 4:4:4 camera and workflow certainly describes quality you deserve even for bump- downs, but be sure to get something with both fast editing workflow and real live pickoffs so that the camera you choose isn`t a burden.
You can e- mail me on a relatively low priced set of cameras and accessories that I can`t afford, at this time. educationalbroadcasting aaat hotmail.com

[Fred Jodry] “Why are you de- interlacing a 30 frames per second (60 fields) interlace camera feed? “
The is not deinterlacing nothing. He has “Field Output: Same as Source”, that means no de-intelacing.
The workflow and setting is full of mistakes.He is making an strange 1280×720 Interaced movie, which is fully off-standards. 1280×720 is always Progressive.
That’s also not a DVD size.
Why to go 1080 > 720> NTSC?[Fred Jodry] “see, antialias setting- 100, detail level setting- 100, and automatic gamma correction- on, at the same time.

He is pointing to the Compressor setting.
You are talking about color printers and scanners and things that have no relation at all.
This is video.
