Quality degradation when editing a WMV file

I have a long duration WMV file (more than one hour) that I want to edit, with the goal of creating multiple files that can be uploaded to YouTube. The file is recording of a PowerPoint presentation with voiceover. It was delivered live on Webex (Cisco's online meeting service), recorded using Webex's built-in recording, then converted from their proprietary format (file extension .ARF) to WMV using the converter utility that Webex provides.
The resulting WMV is quite large (approx 150 MB) and quite sharp/clear to watch/listen when played in the Windows media player.
As stated above, I want to edit the video into chunks that are 15 minutes or shorter, and post to YouTube.
I am using Adobe Premiere Elements v. 8.
So, I do my editing, resulting in content that is less than 15 minutes. I go to the Share tab, click on Personal Computer as the type of share, and choose Windows Media. The file renders. What results is a new WMV that, when played in the Windows media player, has just awful visual quality - the smaller text in the PowerPoint cannot even be read, whereas it was quite easy to read in the original WMV recording.
Any ideas how I can get output that is as good as my original recording?
Is it really necessary to "re-render" the project, since I am going from WMV to WMV? Can't I just snip/delete to get the content that I want to keep, without rendering?

I am still struggling to get a slide show of decent clarity. Am looking at the article you mentioned - http://forums.adobe.com/thread/450798?tstart=0 – but it raises a number of questions for me.
I’m working on Windows Vista with Adobe Premiere Elements v. 10 (I have upgraded). I also have Adobe Photoshop CS3.
You write “This workflow is for NTSC 4:3 720x480 with a PAR (Pixel Aspect Ratio) of 0.9. If your Project’s Presets are different, use those specs to resize to.”
That’s a good place to start. The slides I am working with are TIF images extracted from PowerPoint and saved at 300 DPI. Their default size is 3070 x 2302, but I can open them in Photoshop and resize.
My goal is to create a slide show for uploading to YouTube. I have already extracted the audio as an AAC file and will add that in.
Given my goal and the materials I am starting with, what are the ideal pre-sets to choose when I begin the project?
Or, how do I choose the Project Presets that you use? The default project settings (shown in the dialogue box where I give my project a name and storage location) appear to be NTSC-AVCHD-AVCHD LITE 720p24. If I click the “Change settings” button I am shown a number of choices (for example, the sub-categories within NTSC are AVCHD, DSLR, DV, FLIP, Hard disk flash memory camcorders, and HDV. Which matches the “NTSC 4:3 720x480 with a PAR (Pixel Aspect Ratio) of 0.9” that you use?
4:3 refers to the image’s aspect ratio, correct? I did not look at every Project Preset that is offered, but in the ones I did look at, I did not see a 4:3 aspect ratio specified…
Can you clarify?

After updating itunes 4.10 when editing tags in file adds two covers. This problem is represented as in 10.6.8 and in 10.7.

After updating itunes 10.4 when editing tags in file adds two or three covers. This problem is represented as in 10.6.8 and in 10.7.
Earlier albums were edited with the same cover.
or 3

I think I have the answer.
I was experiencing the exact same problem. I tried lots of different things but what I think works is to exclude your iTunes folder from Spotlight. Open the System Preference for Spotlight, click on the Privacy tab, and then drag your iTunes folder (in your user/Music folder) into that window pane. In fact, I think it is faster when I am fixing tags!
Let me know if it works for you too.

Objects are designed to be used in an HTML document. Snippets are designed more for Code View.
The only reasonable way I can think to get around this limitation is to create a temporary HTML document with either a <script> or <style> block, insert the desired Object, then copy the result to the desired .js or .css file.
What exactly are you trying to do? Maybe some details could remind me of some other way to do what you want.
Hope this helps,

Is there quality degradation when going avi to VOB and back?

Hi,
Long time home editor with Pinnacle and now Adobe. But things I have always wanted to know:
Storage solutions
If I burn a DVD movie and want to bring that movie back into Premiere will the quality degrade in the new project?
Can I get more video onto a DVD as a DVD movie than storing the avi on DVD?
If so, I would be inclined to store video in DVD movie format as long as I can get the quality back when I grab the VOBs for other editing.
Thanks
Phil

Yes. If you start with a DV-AVI Type II file, you have a very lightly compressed file. When you go to DVD-Video, you have compressed to MPEG-2, but with SD material, played on a TV, you will still have an image, that is as good as it gets. Now, you bring that MPEG-2 into Premiere to re-edit, and the file will either be converted to DV-AVI Type II, by Premiere, or by a 3rd party program. It will be slightly degraded at that point. Where the hit really comes in is when you then Export that to DVD-Video via MPEG-2 compression yet again.
For my archiving, I keep the tapes, then Archive (I use Premiere Por's Project Manager, but PE has Archiver), to keep my Captured DV-AVI Type II's, plus the full Project. These go onto a series of 2TB external hard drives. If I anticipate needing to just burn additional DVD's later on, I'll burn to a folder, and keep that intact also. Otherwise, one can make a duplicate DVD from a "master," and not have to re-Transcode, or re-Compress.

Pages Image Quality Degrades When Dropped from Desktop or Inserted

I'm having a problem with image degradation when dropping an image from my desktop into Pages. Even though it's a large file, the quality and resolution is obviously reduced when it's dropped into Pages. I can view the file on Preview and in Pages side-by-side and see a dramatic difference.
I'm trying to keep the total file size of a Pages document smaller and more manageable. I'm a photographer too, so I'm familiar with the file size needed for proper resolution, but I'm just not seeing it come through in Pages.
Anyone else having a similar experience? Any ideas what could be wrong?
Thanks!
-Dan

Hello
Not really surprising.
Pages works using a given resolution (I don't know which one).
When you display a picture from an other app, the res is not the same.
As Pages goal is to print documents, I may easily assume that to spare time, the algorhytm used to display on screen is not a high quality, keeping the high quality one to build the map to print.

Using Aperture 3.51 I am having frequent crashes and freez ups when editing Canon raw files?

HI,
I have an IMac with 4 G of Ram and am using Apeture 3.51. When trying to edit CS2 raw files I experience frequent crashes and freez ups of the whole computer. Any suggestions?

You didn't mention any color calibration being done on your monitor. This is an essential part of any color-correct workflow. What are you using to calibrate your monitor (and your printer)?
Print profiles (for soft-proofing as well as printing) are for specific combinations of paper & printer. The nine you have are each, most likely, for a common paper (perhaps mfr'd by Canon) to be used with your printer.
I don't know what you mean when you say "I choose a high standard print option".
Have you read the User Manual chapter on printing?
Printing Your Images
There is also a good appendix on calibration:

I have found that iMovie stalls when converting a wmv file

and when it does work, it takes way to long to complete the 2step process.
Is there a solution to my problem?
Thanks,

Hi
iMovie usually can not use .wmv files.
.wmv - is no Video-Codec - but a container and can hold a variety of codecs - most of them in need to be converted to a Codec iMovie can use.
If it opens in QuickTime-player, then open Inspector [cmd+I] and read
- Video formatted as (Codec) : nnnnnnnnnnnnnnn
- Frames per second : yyyyyyy
What does it read ?

Premiere only shows audio when importing a .wmv file

I have a 30 sec spot that is a .wmv file. It plays normally in Windows Media Player, plays normally in Bridge, but when I import it into Premiere CS6, it shows it in the project file as a .wmv, but when I pull it onto the timeline or put it into the source window, all I see is an audio file. What happened to the video? Why won't it import also, I know it's there because it plays outside of Premiere just fine. PPro is supposed to import wmv files but where's the video?

Buy the latest version of Nero, import the problem file to a DVD or Blu-Ray project then use the Export function. I have been amazed many times how many file types I cannot import to Premiere or Media Encoder that Nero can import and convert to something Premiere can work with.
Just yesterday I was given a 720P wmv file where Premiere gave me a perpetual "Media Pending" image for the video. Media Encoder likewise gave me a "Rendering" message that lasted forever. Nero allowed me to import the file then export as an AVCHD file with the m2ts extension which Premiere can handle.

No video when playing a .wmv file?

I have a problem with a .wmv file. When I play it in QuickTime or VLC, I hear audio only, but no video. I have the latest Flip4Mac plugin and have no problems playing other .wmv files. The first time I played the file in QuickTime, as was directed to the Apple QuickTime components web site (http://www.apple.com/quicktime/resources/components.html?os=OSX&ctype=696d6463&c subtype=4d535332) because "Additional software is required by QuickTime to playback this media...". But I see no plugin on that web site that would be applicable.
I would be grateful for any ideas as I want to purchase educational videos from this vendor, but can not if their files won't work on a Mac. The 43MB file can be downloaded here for testing: http://files.me.com/pschannong/x20p20
I run 10.5.6 on an Intel Mac.

Don_McCracken wrote:
Thanks. That explains it. The person who made the .wmv file says it was made with Camtasia Studio. Do you have any idea what he might have done for it to choose this MSS2 codec over something more universally compatible?
Camtasia is a screen capture application for Windows (like Snapz Pro for mac). We use it here, it works quite well but you get WMV files and tough darts, I guess if you want other than that. I presume real time capture of activity on the screen calls for a codec simple enough to keep up and not drop frames. It does work quite well though.
Play it on WMP in Parallels, Boot Camp, etc.

Best Quality import when editing with a DVD master?

I have been on a project, that is nearing online, that has a large amount of footage that I have had to import off of DVD. I have been using Streamclip's "Apple Motion Jpeg A" setting at 100% when I have converted files to QT. Anybody know the best way to get this material off DVD and into QT at the best quality? The footage is so bad, that it may not make a difference, but I thought I would try. Anybody use any treatment tricks when working with old, home movie type footage, to "spruce it up" and help it not stand out so much?
Thanks for your input.

The question would be; is the footage bad only because it is from heavily compressed DVD-Video? Or is it bad because it's old home movie footage? Or a combination of the two.
Since it is old home video footage, I'd suspect a fairly low quality camcorder was used. If that's the case, I'd convert the footage to the Apple DV/DVCPro codec using MPEG Streamclip. Or simply capture the footage through a DV device while playing the disc in a DVD player.
Once it's on your system, try using the 3-Way Color Corrector filter to enhance the contrast and control the chroma levels.

Performance degradation when using proxy.pac file with FF ESR 31

With Bug 923458 many people complained about a performance issue compared to other browsers when a proxy.pac file is used.
The issue initially reported with the bug was resolved for ESR25 according to the statistics, but the general performance issue remained.
I had the same issue with ESR24 and ESR31.3 .
I was testing with www.bild.de.
It took about 40 seconds to load the content completely. Without the proxy.pac file it took about 10 seconds.
I added a few alerts to the pac-File in order to get logs within the console for some analyses.
I found the following:
1. the pac.file is executed for every request, no matter if the host changed or not.
With us the pac-File checks for IP-Adresses and host-names only.
It is not necessary to execute the pac file for each and every request to the same remote host.
So the question is, if we are able to disable this behaviour via about:config?
2. the content referenced by www.bild.de seems to be loaded sequentially and with a delay
The overall time consumed by the proxy.pac file executions was about 4 Seconds compared to the 40 seconds of overall load time.
So I checked the delay between executions of the pac-file and found an overall delay of 40 seconds. I expect that the delay between the calls to the pac-file is caused by the retrieval of contents from the remote host.
So why are the requests executed sequentially?
Hint: Due to the times necessary for executing the pac-file and downloading the contents from the remote host, I would expect the logs generated by my alerts to be mixed (especially if myIpAddress took 1 Second). But the log is cleanly ordered by URL. (see attachment)

Hi guigs2,
thanks for your response. As we only use myIpAddress once within our pac-File and only rely on dnsDomainIs(), ==-Comparisons and shExpMatch() and the sum of all pac-Executions was about 4 seconds compared to 40 seconds overall load time, I do not think that dns resolving is our issue.
I checked the seetings of the configuration you mentioned above. It is set to "false", so the client would try the resolve the dns names. Our admin told, that we do not use socks-Proxies, only http-Proxies.
Regarding sequential load of the contents included on www.bild.de from other web sites, I attached a screenthot.
Please note the red highlights. These show the start time in milliseconds of the pac-execution. I added this as a kind of id which represents a unique identifier together with the URL if the log items are mixed. But they are not, instead they are cleanly ordered by URL (for all 360 pac-file calls).
Moreover in the picture you can see the delay between the end of the last pac-file execution and the next one (blue timestamp in millisonds compared to the red timestamp of the next row saying "entered proxy.pac"). The delay sum up exactly to the 40 seconds the FF took to load the page completely.
Alone the fragment shown represents a delay of 630ms between the pac-file executions. If the contents would be loaded in parallel, there should be no such delay.

Audio quality degraded when imprting FLV file to Flash FLA

Hi,
I have created a FLV file using Adobe Media Encoder CS5.
I have played it back on Several Media players and it sound fine.
I import it into a Scene in Flash CS5 aand when I preview the Scene the audio has degraded and sounds terrible.
The audio is mono at 48 kbps.
I cannot find any controls or options to edit the audio of the video.
I have rendered it out several times using different settings but it alway plays back the same highly compressed tinny sound.
Any advise?

Try with your publish settings in flash to adjust your audio quality while publishing, look into the below screenshot:

Major Quality loss when editing in Iphoto 09

Hi,
I am a new user to Imac and Iphoto and I saw that when I edit an Image in Iphoto, I loose a lot of my original data.
I have found that I can return to the original picture, but I wish to edit (especially using the CROP function) then print the Image on 20x30 cm size and therefore I need all the quality I can get.
When I Crop either JPEG or .RAW formatted images (for example 10 MBytes in size) even if I select the COMPLETE image, I am left with only 4 or 5 Mbytes of data.
It gets much worse when I really Crop a part of the picture.
A 12 Mega pixel photo should supply sufficient data to cover a complete wall, but for some reason a lot of quality is lost when I use any of the editing features.
Am I doing something wrong ?
Should I change any of the settings ?
Thanks for your advice

Welcome to the Apple Discussions.
the only difference is that Iphoto took my quality !!
Are you basing the "quality" loss on visual appearance of the photo or on the resulting size of the jpeg file? If it's the latter that is really not an accurate method. True, some information is lost with a jpeg edit and save (only the first edit in iPhoto results in additional jpeg compression) but, in my experience, you would have to print a VERY large print before seeing any noticeable image degradation. I've compressed jpegs as high as 60%, i.e. a quality setting of 40, and for most all uses up to 5x7 prints haven't seen noticeable image degradation. However, I realize image quality is subjective and open to individual interpretation.
So unless you are visibly seeing image degradation I wouldn't worry about the file size reduction, especially in iPhoto as it's compressed only once no matter how many edits are made and saved. Apple uses a compression algorithm that gives the best image quality for the amount of compression it uses.
The following is from the Usernet FAQ site article "JPEG image compression FAQ, part 1/2':
Subject: [4] How well does JPEG compress images?
Very well indeed, when working with its intended type of image (photographs and suchlike). For full-color images, the uncompressed data is normally 24 bits/pixel. The best known lossless compression methods can compress such data about 2:1 on average. JPEG can typically achieve 10:1 to 20:1 compression without visible loss, bringing the effective storage requirement down to 1 to 2 bits/pixel. 30:1 to 50:1 compression is possible with small to moderate defects, while for very-low-quality purposes such as previews or archive indexes, 100:1 compression is quite feasible. An image compressed 100:1 with JPEG takes up the same space as a full-color one-tenth-scale thumbnail image, yet it retains much more detail than such a thumbnail.

JDEV TP3 freezes when editing big .jspx files

Hi,
I have mainly worked with small files in JDEV TP3. At the moment I am testing the ADF Faces Rich table component. I have a huge table, the markup is over 700 lines long and when I edit this file JDeveloper freezes for several seconds, repeatedly. This occurs when I edit the file. Normal text input, copy and paste, selecting.
I tried to run JDeveloper with JDK 1.5 and 1.6.4. No difference. When I close and open the program. No difference. On all the other - smaller files < 100 lines everything works fine.

Hi,
any chance you can provide a testcase ?
