Maintaining Quality after Logic!!

i have what seems to be a basic problem (im a newbie) ive been trying to solve this for weeks now cant get help on other forums!!
what i did was take an mp3 instrumental and recorded vocals on it (i set it to 24 bit recording).
what i want to do is maintain the quality i get in the logic program in either a wave or mp3 file but when i bounce the quality goes way down (bass seems to spike or be too much...again im a newb) also the vocal quality goes down....
im obvously doing something wrong..please help im dying for people to hear this song!

thats my problem, i thought that was the obvious answer but when i bounce to 24-bit wav its still bad quality, sounds exactly the same if i bounce to mp3, im doing something wrong...any ideas?
(when i say bad quality i mean the bass is now too loud and sounds bad, minor vocal decrease in quality)

How good is H.264 quality after multiple re-renderings.

How well does a high bit rate (e.g.30Mbps) H.264 maintain its quality after multiple re-renderings. I believe MPEG2 suffers quite a bit after several re-renderings, how does H.264 compare?
Thank you.

It's probably best not to do it. H.264 is a lossy compression format. Each pass will degrade the media to some degree.

Very poor video quality after transcoding in Adobe Encore CS5.1

MERRY CHRISTMAS AND A HAPPY NEW YEAR!
I have very poor video quality after transcoding the video file (MPEG) in Adobe Encore CS5.1. Below you see my used settings in my filmproject.
The problem exists after transcoding in Adobe Encore CS5.1. I checked all steps and found out that there is no problem until transcoding. My exported file in MPEG has very good video and audio quality.
Facts:
1. Camcorder: Panasonic AG-AC160AEJ
Operating System : Windows 7, 64 Bit, Ultimate edition
Source files: MTS files
Recording settings (clip settings):
Type: MPEG Movie
Image Size: 1920 x 1080
Frame Rate: 25,00
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Pixel Aspect Ratio: 1,0
2. Sequence settings in Premiere Pro
Sequence was created from Clip directly with settings above.
3. Exporting settings in Adobe Premiere Pro:
Match sequence settings was activated. Now other changes were set.
4. Exported File:
Video
Image Size: 1920 x 1080
Data Transfer Rate: 25920 kBit / s
Frame rate: 25
Audio:
Bit rate: 384 kBit / s
Channels: 2 (stereo)
Frequence: 48 kHz
5. Transcoding settings in Adobe Encore:
I used different transcoding settings such as automatic DVD Transcoding, CBR and VBR.I also set “use maximum render quality”. But all results were always the same: very poor quality.
Why does the encore transcoding cause such bad video quality?
How can I solve this problem?
Please help me soon.
Best regards.

Hi Ann,
1) I did not only „Automatic (based on source)“ options in my tests, but also many other customized options.
The results are very poor. I have done a new test with the following settings. The result is also poor:
Download link: http://www.klavierlehrer-bayern.de/download/test_mpeg2dvd_1.m2v
Export Settings:
Format: MPEG2-DVD
Preset: Custom
Codec: MainConcept MPEG Video, Quality: 5
Frame Rate: 25 fps
Field Order: Upper
Pixel Aspect Ratio: Automatic (based on source)
Render at Maximum Rate: [active]
Bitrate Encoding: VBR, 2 pass
Minimum Bitrate (Mbps): 5
Target Bitrate (Mbps): 9
Maximum Bitrate (Mbps): 9
GOP Settings
M Frames: 4
N Frames: 12
Use Maximum Render Quality: [active]
Multiplexer: None
2) Why shouldn’t I use the “Match Sequence Settings” in exporting? Because of the big output file size?
I used it and the results are very good as I expected:
Download link: http://www.klavierlehrer-bayern.de/download/test_MatchSequenceSettings.mpeg
Export Settings
Match Sequence Settings [selected]
1920 x 1080, 25 fps, Upper, Quality 50
User Maximum Render Quality: [active]
3) I tried also Dynamic Link in PremierePro (to Encore).
The results are also poor.
4) I will test also LagarithLoslessCodec and frameserving +DGMPGDec. But the video is vertical long drawn-ot.
I think I did not use it correctly.

Out put quality after DVD authoring is less than .mov file that fcp source

Anyone know why I would be getting a notable drop in quality after i make a dvd?
going from HF11 Cannon shot at 17 mbps into FCP. then out to compressor and using the high quality dvd setting.
then when i play my dvd i notice for example jaggies on some objects yet if i look at the .mov file that was ignested into FCP that has almost no jaggies. is there some setting i'm missing?
everything was set at 16:9 1080x720.
I'm up to my pits in information overload.
Someone with some idea or experience please help me out. thank you so much.

Here are some of your options as you look toward HD encoding.
Using Toast, Encore, or FCS 3 you can move toward blu-ray authoring and encoding. In Toast and FCS 3 you can make AVCHD disks which are blu-ray disks put onto single or dual-layer DVDs which is a huge cost savings. Your encoding is limited to 17 Mbps, but in h.264 that will still allow for decent quality. Encore will let you design a complete disk but it doesn't make AVCHD disks - you'll need to jump through some hoops in order to take an Encore project (but it can be done). Here's a workflow for that. As a side note this workflow is for using Final Cut Express - in FCS you have the added benefit of being able to work with 23.98 fps timelines.
Your other option it to move toward digital outputs. You can use something like an AppleTV to playback HD content (it'll be reduced to either 960x540 @ 30 fps or 1280x720 @ 24 fps. Or you can use one of the various media streams on that market now (SlingCatch, Western Digital WDTV, etc.) Personally I'm a big fan of the WDTV from Western Digital. It's affordable (around $100) and plays back all kinds of formats in HD up to 1080p. Plus it reads from flash drives or hard drives via USB. You can encode MP4 files for these types of devices in QuickTime, export from FCP, MPEG Streamclip, Compressor, etc.

How can I add the audio content cd after logic finished installing ?

There was an eror installing the Audio Content CD 1 and I did not notice. Everything else installed properly, Audio Content CD 2, Jam Pack, but how can I add the Audio Content CD1 after Logic has finished installing?
If you can help me please be very specific as to how to do it so that I can follow the directions properly.
Please help me.
Thanks

Hi
You could re-run the installer, or, once you have updated to Logic 9.1.8 you could use the "Download Additional Content" function in the Logic Pro menu. It will tell you what is installed and what is incomplete.

L7780 poor print quality after not using for 6 months

Poor print quality after not using my printer for about 6 months. Ran thru the tools (clean printhead, aligh, etc . . .) didn't help. Replaced all chartridges, still no help.
I'm fairly tech savy, been in IT for 27 years starting with hardware support.
Question, can I manually clean the printheads or should I just replace. I would rather try to clean them manually after just shelling out > $ 170 on new chartridges.
thanks
Brent

Hi @Brentl
Yes, you can clean the printhead and the inside of the printer. The following document will help; 'The Following Printheads are Missing or Damaged, Replace the Printhead' Message Displays on the All....

Poor quality after timeline rendering of after effects dynamic link comp.

One of my typical workflows involves dynamic linking AE comps into Premiere- Often I can playback the timeline in Premiere without rendering and achieve great results with no dropped frames. This scenario is ideal since I need to play out sequences in premiere passing them through a Matrox MXO2 LE box to capture them on another system. However, I have noticed recently that if I need to render the Premiere sequences before playback because the dynamically linked AE comps are more complicated, I lose quite a bit of quality after rendering.I've searched around and read about different quality settings in both AE and PP and I can't seem to find any settings that affect this process. Pause and playback quality are both set to full, tried checking rendered maximum depth/quality in the sequence settings and I still can't get this right. I am perplexed since I would think that results would be better post-render.
Dynamic Linked Clip Unrendered
Dynamic Linked Clip Rendered:
-A note about my settings:
AE comps:
720x480 (containing downscaled HD video)
PAR: D1/DV NTSC (.91)
29.97fps
Resolution full 720x480 1.3 MB per 8bpc frame
PP Sequences:
720x480 (.9091)
29.97p
WINDOWS 7 - Adobe CC
Intel Xeon(R) 12 cores 2.40ghz
Nvidia Quadro 4000
12g RAM

The video preview settings were set to DV NTSC. I'm not sure why I didn't think to look at those settings. I went ahead and downloaded the Ut Video Codec Suite and things are now looking great - just like they do when I do not render the sequences. I am noticing now that my HD sequences usually are setup to use Matrox's Mpeg2 I frames only codec.
Is the lossless codec choice always the best/most efficent choice to be used for the preview codec? I assume if I was not dynamic linking I should match this codec with the codec of the files in my sequence, is this correct?

Video Quality After Transcoding Disappointing In CS4

To All,
I am new to Encore so my situation may be as a result of my ignorance. I have come to appreciate HD video so I purchased a Hauppauge HD PVR to capture programs in HD. I have captured multiple HD video clips in a .mp4 format. I bring those clips into Premier Pro CS4 and when viewing them individually, they look great - crisp, clear video that looks fantastic. Once I have put my video together (consisting of several clips that is about 1 hour long total), I then select Adobe Dynamic Link and send the project to Encore to burn onto a 25GB blu-ray disc. I have tried 2 or 3 different settings in Encore and the result is a video that is 1920 x 1080 full screen but the video quality is disappointing. It's as though a "soft filter" is used in the video effectively taking away the crisp, clean video I see in the original clips I imported into Premier Pro - the very thing I have come to love about HD (ex: beads of sweat on faces, seeing individual strands of hair on someones head, etc.). Am I being unrealistic to expect the same quality video after being transcoded in Encore that I see in the individual clips I originally inported into Premier Pro or I am I just doing something wrong? Thanks for the help in advance!

It sounds like you are familiar with Encore. Let me ask this general question. Can one expect to achieve the same video quality after transcoding in Encore as the video originally imported or is some loss inevitable?
Actually, this should answer both questions.
What happens first is that your capture device/card will compress the signal originally. You then Import this footage into PrPro for editing. It will not be edited in it native format, as it is compressed and is also GOP (Group of Pictures) format, i.e. there are not real Frames to edit. These must be created for Frame editing. Now, you're working pretty much in a good replication of your initially compressed files. Here comes the problem: you now wish to Export to a BD. You need to re-compress and Transcode this material in PrPro to a format that can be used on a BD player. A second compression and Transcode will need to take place.
As an example, lets use FAX machines and desktop printers. You create a document in Word and print it out with your 1200 dpi desktop printer. This is a pretty high quality document. It's like the HD TV signal. Next, you run your original document printout through your copy machine. This still looks pretty good, but not up to the original. This is what your capture card has now produced. Then, you take that copy and FAX it to a friend. It now starts to show degradation. This is like that second compression and Transcoding.
Not sure what a better workflow would be for HD TV capture.
Good luck,
Hunt

How to maintain video quality after resizing?

I have a 640 x 360 px video that I want to resize to fit a 480 x 270 px flash movie. When I resize the video to fit the smaller stage the image quality suffers, it looks like low res. When I crop to fit, it looks fine. Is there a way to maintain image quality when reducing size?
link to file: http://www.moongraf.com/flashvideo.html

I have nothing on this computer aside from Adobe and a few other audio apps. This is a dual Xeon 6GB system. I work in IT and am MS certified. I do not think it is the system. I am using AE CS6. =A0Keyboard is set to its defaults. I do not touch the keyboard mappings. The effect brings the clip down to 10% or so. How should it be resized? SHift - click and drag works in all of my apps like Photoshop, so it isnt the kb or the system. Is that the way it is supposed to be done in AE? If you have AE, are you able to try this to see what I mean?

Value not getting maintained even after maintain in some situations

There is a scenario for maintaining the quality testing charges after PGI. in cash sales customer. after they are updating in the invoice. so there is difference in order value and invoice value,
This difference needs to avoid.
This condition type (like ZQTC) needs to indicate the user at the time of sales order processing.
Please help me for configure the same,
Note: this condition type should be maintained only for Quality testing charges applicable for cash sale customer.

How to hide row from table after logical delete

Hello.
I am using Jdeveloper 11.1.1.3.0, ADF BC and ADF Faces.
I want to implement Logical delete in my application.
In my Entity object I have Deleted attribute and I override the remove() method in my EntityImpl class.
    @Override
    public void remove()
       setDeleted("Y");
    }and I added this condition to my view object
WHERE NVL(Deleted,'N') <> 'Y'in my page I have a table. this table has a column to delete each row. I dragged and drop RemoveRowWithKey action from the data control
and set the parameter to *#{row.rowKeyStr}* .
I what I need is this:
when the user click the delete button I want to hide the roe from the table. I tried to re-execute the query after the delete but the row is still on the page. Why execute query does not hide the row from the screen.
here is the code I used for delete and execute query
    public String deleteLogically()
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding = bindings.getOperationBinding("removeRowWithKey");
        Object result = operationBinding.execute();
        DCBindingContainer dc=(DCBindingContainer) bindings;
        DCIteratorBinding iter=dc.findIteratorBinding("TakenMaterialsView4Iterator");
        iter.getCurrentRow().setAttribute("Deleted", "Y");
        //iter.getViewObject().executeQuery();
        iter.executeQuery();
        return null;
    }as you see I used two method iter.getViewObject().executeQuery(); and iter.executeQuery(); but the result is same.

Thank you Jobinesh.
I used this method.
    @Override
    protected boolean rowQualifies(ViewRowImpl viewRowImpl)
      Object attrValue =viewRowImpl.getAttribute("Deleted");
        if (attrValue != null) {
         if ("Y".equals(attrValue))
            return false;
         else
            return true;
        return super.rowQualifies(viewRowImpl);
    }But I have one drawback for using it, and here is the case:
If the user clicks the delete button *(no commit)* the row will be hidden in the table, but when the user click cancel changes the row is not returned since it is not returned due to the rowQualifies(ViewRowImpl viewRowImpl) (the Deleted attribute is set to "N" now).
here is the code for delete and cancel change buttons
    public String deleteLogically()
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("removeRowWithKey");
        Object result = operationBinding.execute();
        DCBindingContainer dc = (DCBindingContainer)bindings;
        DCIteratorBinding iter =
            dc.findIteratorBinding("TakenMaterialsView4Iterator");
        iter.getCurrentRow().setAttribute("Deleted", "Y");
         iter.executeQuery();
        AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
        adfFacesContext.addPartialTarget(this.getTakenMaterialsTable());
        return null;
    public String cancelChanges(String iteratorName)
        System.out.println("begin cancel change");
        BindingContainer bindings =
            BindingContext.getCurrent().getCurrentBindingsEntry();
        DCBindingContainer dc = (DCBindingContainer)bindings;
        DCIteratorBinding iter =
            (DCIteratorBinding)dc.findIteratorBinding(iteratorName);
        ViewObject vo = iter.getViewObject();
        //create a secondary RowSetIterator to avoid disturbing row currency
        RowSetIterator rsi = vo.createRowSetIterator(null);
        //move the currency to the slot before the first row.
        rsi.reset();
        while (rsi.hasNext())
                currentRow = rsi.next();
                currentRow.setAttribute("Deleted", "N");
        rsi.closeRowSetIterator();
        iter.executeQuery();
        AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
        adfFacesContext.addPartialTarget(this.getTakenMaterialsTable());
        return null;
    }as example, if the user initially has 8 rows, then deleted 2 rows, in cancelChanges only 6 rows appears. and the deleted rows are not there??
any suggestion?
