Frage von Polyesther:
Following problem:
Material was rotated on HDCAM (studio, black object against a black background).
In the editing with Avid DS Nitris, so uncompressed HD looks wonderful (HD tube monitor). For the special projection synonymous everything was good (also HD). Only wanted the customer to complete a normal DVD. The light through the composite produced reflections and sharp edges were now a major issue: education and / or stair Alias | Wavefront Mayaing in very strong shape was the result. There must be possibilities but give synonymous after Downconvert PAL after the high resolution of HD material benefit. Even if we would have rotated to Digi, the result would be satisfactory for the DVD.
Our solution approaches (unsatisfactory):
1. convert files into the HD DVD MPEG file through TMPEG
2. Downconvert after PAL by AVID DS Nitris
3. Application of the "Deflicker Filters
Must it go, or how is it that HD films like "300" on a PAL DVD look good? Do I really hardware encoding fall back?
Thank you for qualified opinions
Antwort von Pianist:
What happens if you go the usual way, that is export a Quicktime Reference and then MPEG-2-encoding using squeeze? S.sich This looks very good, so I do not know why there should be problems.

Antwort von PowerMac:
Yes. The above approach sounds unusual for me and wrong.
Why is the HDCAM to MPEG DVD file through TMPEG "?
One expects a very s.Schluss in order to MPEG!
So only in HDCAM PAL Avid to make. Then to MPEG-2. This is synonymous all at once Cleaner, MPEG Streamclip ...
Antwort von WoWu:
@ Polyester ..
... Your "uncompressed HD" is the 8bit or 10bit?
Antwort von Pianist:
So only in HDCAM PAL Avid to make. Why? He is surely right in his environment will remain high and squeeze out of there.

Antwort von PowerMac:
For quality reasons, it is often better, you do so. The best is the Downconvert with AE, where everything is separated.
HD-> SD, then to MPEG-2 is usually the best quality (such as with MPEG Streamclip, then with the CCE SP2 to MPEG-2).
HD-> MPEG-2 SD is as synonymous with Squeeze, Cleaner, Compressor. Is not always as the "Burner." I prefer to do it in two steps, because in case of doubt, the best manual Downconvert the automatic in Cleaner, Squeeze superior.
So is the "workflow" of the initial poster described either wrong or false.

The man is amateur and it has done wrong with Streamclip. The workflow of Uli Plank is the best quality. The programs listed here are definitely better than that Streamclip is this still free. The editors make a lot of synonymous HDV to SD the same way.
Antwort von Pixelorkan:
In any case only deinterlace and then resize to avoid frayed edges ...

Antwort von TheBubble:
Education stairs or Alias | Wavefront Mayaing in very strong form Alias | Wavefront Mayaing artifacts can be accessed by the upstream sampling, lowpass filter fix. In general, however, should Resampler already taken into account and itself.
Experimental yes you can take a (slight) blur filter applied before resampling.

What has the MiWe your opinion wrong, Powermac? MPEG Streamclip works only with real and current Quicktime. Better still Quicktime Pro. Quicktime Alternative or so is not suitable.
Antwort von wolfgang:
Well good to know ... I myself have not tested. Which version of Quicktime should it be? 7.2?
Antwort von PowerMac:
Always the latest! ;)

Thank you in advance for the numerous replies.
Maybe I have the problem does not sufficiently describe
but of course we have the synonymous variant "Reference and then export
convert "tried. Whether I use squeeze now, or is there TMPEG sausage.
The result remains the same. Stairs without end. Sorry, I am synonymous sure that this problem not by a free encoding tool solved. We are talking about professional post-production. From experience I know that this problem is not just our (even a DVD a naming-term concern car get the same problem =), but often simply tolerated because it is the customer does not always recognize. If you own the material but in such good quality are available, then the heart bleeds, when I watch the DVD. I am pleased when your next reply brisk.
Thank you

Maybe I have a problem not adequately described, but of course we have the synonymous variant "Reference to export and then convert" tried. Can you somewhere take a screenshot in original size upload? "Black object against a black background" first times sounds more like "white eagle on a white background (Ostfriesische national flag).
Mir is still unclear when and why there are stairs to be formed. I would not even synonymous in the 1440-anamorphic recording of HDCAM slide, although it is actually a fragile vulnerability of the system.

Will you next week, a link to you. If not faster.
The stairs entsehen incidentally, only after the PAL conversion, or if directly from the HD DVD File Ref MPEG file was created. The black object borders in contrast to the white eagle set by Highlights and reflections from the black background.
These fine lines of light and reflections certainly reinforce the problem.
Thanks for the sympathy

stupid question. what happens if you get your material of an HDCAM maz on composite runterkonvertieren it? THEN the problem is as synonymous? if so, is probably s.der footage ...

I would make the problem when looking for interlace and resize.
this problem has already been discussed in some thread and so here:

then the results should be determined by process and operational
depend on the tools (and that should be synonymous for professional
productions apply).

(...) Sorry, I am synonymous sure that this problem not by a free encoding tool solved. We are talking about professional post-production. From experience I know that this problem is not just our (...) I know this problem is not. Such problems exist only when one is working incorrectly. And just because you work with Nitris, it's still a long way, about mistakes that you're sublime and the same software fault. And I'm talking about synonymous with professional post-production. The stories of your workflow is incorrect. Signs it properly (if you've done the dirty), or you know how it does not. MPEG-2 encoding (whether with a 2000 euro with CCE SP2 or freeware) has a very s.Schluss to be covered. You play your first project as a Quicktime Reference from and then calculate it with something to PAL or exportierst same Nitris to a 10-bit uncompressed PAL via Quicktime. Now look at the file, such as Quicktime Player. Are edges and stairs to see? If so, the settings for PAL? Interlaced scaling enabled? Half-twister? Until it's true. No, everything super? Then you can start to MPEG-2 expected. But until now!
