Gerendertes Video (mpeg2) ist unscharf und ruckelt

Rendered video (; mpeg2) is blurred and jerky



Frage von newuser:
Mai 2009

Hello,

my problem is that my camera videos are available in good quality - mpeg2 format, bit rate is set to 10Mbps VBR.

After being cut at the Sony Vegas Studio is the completed movie, also mpeg2, much worse than the original material. When moving, the picture is blurred, with a swivel of the camera, the jerky picture.

Why might that be?
Am happy to answer ;-)

PS:
I work for the first time with Vegas, the studio and did not possess any experience.



Antwort von tommyb:

Then you probably have nothing of the "Project Settings view" - a known bug.

It can identify for your project frame rate and resolution with which the Project is discussed.

There are also presets that make it slightly easier to select the correct settings.

Try it once with "DV SD" and also choose between 4:3 or 16:9 (; widescreen).



Antwort von newuser:

Hi! Thanks for the reply.

However, the project settings, I had already found.
There were recruited including NTSC, I corrected this value to PAL.
The resolution and frame rate should stay or 25 fps at 720x576 - I guess -> my camera provides 704x576: is this a problem?

Can I adjust the Vegas Studio synonymous desired output bit rate of the mpeg?

Otherwise, I'll try it with your proposed times of the preset.








Antwort von tommyb:

No, 704x576 is not a problem. The Project has later s.den merely playing off the little black edges of the pages, but should not be noticeable.

If you exported in MPEG2, then you can adjust the bit rate among themselves. So it is at least in the normal Sony Vegas. Whether in the studio version is so synonymous, I do not know. You have to watch times.



Antwort von Marco:

This part of the project settings has nothing to do with the rendering or the Rendergebnis too. If here is a different resolution of the material is used, does this only on the preview and the preview performance.

Antwort von tommyb:

When an NTSC project and create a PAL video reingeschoben, then adjusts Vegas, the 25 frames to s.The 29.97. When exporting a PAL file is in turn interpolated of 29.97 to 25 frames.

So it does very well from what if you have chosen the wrong settings.



Antwort von Marco:

No no, definitely. The rendering of those project settings will remain completely unaffected. All entries in the project settings, which lie above this narrow horizontal line, have no influence, either directly or indirectly, to the rendering.

The only entries in the project settings, which can make influence the rendering, but not necessarily have to include the deinterlace method and the color depth.

Antwort von newuser:

moin!

thanks for the infos ;-)
I noticed last night that the film has only poor quality on my television, but not on my PC monitor.
So I simply chose not deinterlace times in the project settings and voila ;-) - Picture perfect on Television and Monitor.
How is that really needs a television always an interlaced signal?
Ie synonymous my dvd's, avi's, etc. are interlaced -> this can not be ;-) ... Maybe even one of me can explain it to you ....

Thanks for your time!

Antwort von Marco:

There you have basically resorted to a wrong action, however. The deinterlacing method in the project settings should be the rule not always "mix Fields" (; interpolate aka synonymous to "Fields" are).
That does not mean that because the rendering already a deinterlacing would be applied. This is only the case if, in addition to render settings as field sequence "No (; progressive) is selected.

If after changing the deinterlacing method in the project settings to the value "No" to render the result of improved quality, then this can be done only in interaction with any other action or appearances are deceiving and the improved quality resulting from something else entirely.

Marco



Antwort von newuser:

Where should it be found the render settings?

For me, there is the option "Create Movie". Here, I then have the option to select from various templates (; eg dvd-pal). Other settings I have not s.dieser body - at least I have not found.



Antwort von Marco:

I skipped that you are working with Movie Studio and not with Vegas (; Pro). Since you have no influence on advanced render settings.
And conversely, there has the attitude of the "deinterlace method" actually has a direct impact on the rendering. Paradoxically, is running in Movie Studio precisely in the case, a deinterlacing, if it is below the deinterlacing process, the entry "No elected.
So within of Movie Studio can play with different settings for the deinterlacing process to bring something.

The entries in the upper part of the project settings but synonymous in Movie Studio does not contribute to the rendering, but only the preview.
You can put in the project settings, select a resolution of 200x200, twist the field order set as 0.7 pixel aspect ratio and choose a frame rate of 28.2222 fps render and your result will still not affected and remain clean as long as the correct rendering template is selected. Only the preview is a hopeless project Spanking.

Marco



Antwort von newuser:

* grins * ... This is for the beginner to understand little. When I say "no deinterlacing" pick, a deinterlace executed when rendering.

Is there really a tool with which I rendered festtellen if my mpeg's deinterlace or not? I previously used GSpot, but this information is the tool is not applicable?








Antwort von Marco:

You see it when a video is loaded into the Movie Studio and the preview is set to Optimal (; Full) "while the right-click menu of the preview window, the entry" Video preview window scale to size "is not selected.
If under these conditions, a preview video, which includes fast movements, the frame as viewed through the preview shows a video without deinterlacing narrow, horizontal strips, which were not visible on the same video which was subjected to a deinterlacing, too.
In the project settings but this may be under "Field order" no "selected No. (; progressive scan), otherwise movie studio would do for the preview (; and only for) a deinterlacing.

However, I realize now that the statement that, when setting "No" in general within the deinterlace process is always a deinterlacing is performed, it is not synonymous is incorrect. There are cases where this will end in this kind of effect (; for example) at certain scales, but in other cases, this option has no effect on an alleged deinterlacing has.

Have you done with your rendering synonymous to scale - that was your material may HDV or AVCHD and MPEG-2 was then rendered with PAL resolution?
That would indeed be a case in which it would actually result in deinterlacing, then if the setting is "no use".

Antwort von newuser:

no. the starting material was already mpeg2 (; as it takes the camera) in 704x576 format.



Antwort von Marco:

Then something else has worked together with the setting.

Marco

Antwort von newuser:

hhmm ... what should be. I've changed only this option.

In fact, all of the outstanding movies are interlaced (; according mpeg2 validator), which proves well that this setting in the project properties has no effect on the rendering.

I'm assuming that this setting refers to the input material. Because my input is interlaced material from the camcorder, the setting should be "no deinterlace" actually be wrong.

So what justifies the quality is still a secret ;-)

I prefer to work again with other editing programs, the s.solchen are much more straightforward to use ...



Antwort von Marco:

No, the setting is not related to the input features, but it describes (but unfortunately not really clear) as the internal signal processing of the program makes Halbbildmaterial.
Why is synonymous for Movie Studio, that (the default setting; Fields Mix) usually should not be changed, regardless of whether the original material is now interlaced or not. If in your case, a change in this setting produces better results, however, speaks synonymous not mind working here with a different setting, synonymous when it can not serve as a general rule.

The analysis by MPEG-validator is useless. In this way it can be shown no deinterlacing, but only whether the file ultimately with progressive or interlaced with Halbbildeigenschaft has been saved. The latter is the case with movie studio, even when applied before, a deinterlacing. The result is then a deinterlaced video that with Halbbildcharakter as a purely technical property was saved. The video also contains Halbbildpaare without temporal image differences.
The only reliable method of analysis is a visual inspection in the manner I have described above.

You should make the challenges of such a program operation is not synonymous complicated than it really is. In those project properties should normally not even be rumgeschraubt. The vorschaurelevanten Movie Studio project properties are in pretty much set at the first set and the rest require only in exceptional cases, an intervention.

That occurs with you when it is rendered - no interference in the setting of the deinterlacing process - a marked deterioration in quality, must be in the heart of the matter have a different cause. That's not for me to reproduce. When I rendere with Movie Studio with such high data rates, as you used them, SD MPEG-2 to MPEG-2, is qualitatively discern no difference. And I've changed s.None place any default. MPEG purely in the timeline, without worrying about anything, as MPEG-2 with a DVD presentation from movie studio - and all is well. Easy does it hardly.

Antwort von newuser:

Hello!
First of thanks for your tips and observations s.dieser place!
I find cool that you can muster the patience to weiterzuhelfen me a little ;-)

But the fact is that any editing program (, Ulead, Sony Vegas, Adobe, etc.) as an interlaced video output generated, since the source (; camcorder) is also interlaced.

If the source is interlaced, it should have no problem with my Television (; My television is connected via S-Video s.einen PC). For the PC monitor, I would then have the player (and I use vlc) deinterlace enable or, I assume that vlc recognizes the car.

Then the strange, in my view, that eg the result of Ulead VideoStudio is both s.Television as synonymous to the PC screen looks fine but is the "deinterlace" turned off in vlc player.

For playback of the movie studio of Sony Vegas, I take in vlc-player "deinterlace enable", then I have s.Television a good picture, but the picture is then s.PC ill or in the project settings, "choose a deinterlace" dannn Both pictures are great.

There is a flag that the player indicates that it is a progressive or interlaced material (and this will not set properly in Sony Vegas)?

I have one other question: what should I set that my film will be rendered in 16:9 format?



Andreas



Antwort von newuser:

But what one must mention synonymous:

if I enable deinterlace in vlc player is the quality of the sony vegas definitely better than the output of Corel!
Unfortunately, the possibilities of the studio output in Vegas are confined to a few templates (; for me, there's really only) dvddpal.

Is there a way to maintain my original AC3 2 Ch sound in rendered movie?



Antwort von Marco:

Movie Studio is the identifier for interlaced / progressive correctly. I can here your problem is indeed synonymous with movie studio can not reproduce. It is synonymous as such in circles of Movie Studio users not known.

Do you have perhaps a very short piece of original videos with small file sizes that you could give me time send by mail or make available for download could be?

To render a 16:9 - video, you need to use an appropriate template 16:9. However, there was simply overlooked in the MPEG-Render Templates a variant.
If, for example, Vegas Pro is available, you can tinker to any template itself and the synonymous use in Movie Studio. Perhaps there would be a way through a third person is synonymous to produce usable in Movie Studio template that meets your needs.

AC3 you can integrate via Movie Studio just for the DVD. This Picture and sound are rendered separately for the first DVD with the appropriate templates (; sound then assembled just as AC3) and in DVD Architect Studio.

Antwort von newuser:

I gladly accept the offer, today I'm working tonight at home a piece of film and send you - can you give me your email?

Maybe you can help me even with a template for 16:9 - I know because no one else.


Andreas








Antwort von Marco:

Well there was a small piece of the original movie, right of the camera. One second's enough.

Email Address:

I will be there, but only tomorrow morning mails can.
