How can I avoid video quality loss when burning Canon FS100 footage to DVD?

When I put the footage onto iMovie it looked great, and then I sent it to iDVD to burn onto a disc. After I burned it to a DVD and watched it on my DVD player, I noticed that I lost a lot of the video quality (or at least it seemed). It looks a little fuzzy and seems like it could be much better considering how great it looks in iMovie. Is it just me or does sending it to iDVD make me lose video quality? What is another alternative so I don't lose the quality? I've heard that Wondershare is a good option and that you won't lose any quality burning it from there, is that true? What is my best alternative? A relatively expensive DVD burner? Thanks, any help is appreciated.

A good suggestion was made before me, but I have another twist on the matter.
From Wikipedia on DVD: "Although many resolutions and formats are supported, most consumer DVD Video discs use either 4:3 or anamorphic 16:9 aspect ratio MPEG-2 video, stored at a resolution of 720×480 (NTSC) or 720×576 (PAL) at 29.97, 25, or 23.976 FPS."
Notice that the resolution for a DVD is roughly 700x500, which when multiplied gives you 350,000 pixels per frame. Now compare that with the video resolution of the FS100, which I see on web pages (eg, on dabs.com) is 710,000 pixels per frame.
This means your camera records more quality than can fit on a DVD. Approximately twice as much information. This means half the information is lost during the conversion. That's why you notice a drop in quality. If you burned to a BluRay disk, you'd probably lose nothing, since they store more information per frame. So your alternative is to buy a BluRay burner and play it back on a BluRay drive.
Another alternative is to burn it to a DVD but not in a form that's playable by a DVD, just in a form thats readable and playable by a computer. You will lose no information that way, but it will be playable only in a computer.

How can i avoid restarting tomcat server when servlet is modified?

please advice me that how can i avoid restarting the tomcat server, whenever a servlet file is modified in my application. is their any way ?

No probs. Here's how I do things...
1. Install tomcat as normal (e.g. I install to C:\Apps\jakarta-tomcat-5.5.4)
2. Create a webapps directory in your eclipse project with the following directory structure
MyEclipseProject
   - src
   - conf
   - webapps
      - MyApplication
         - META-INF
         - WEB-INF
            - classes
            - lib
            - pages3. Set the project's output folder (e.g. bin folder) to webapps/MyApplication/WEB-INF/classes
4. Put all your jar files in the lib directory
5. Put JSPs / HTML in the pages directory (you may also want to create additional directories for TLDs, config files etc)
6. Ensure your web.xml is in the WEB-INF directory
7. Although it isn't essential I create a context.xml file and store it in META-INF, e.g.
<Context reloadable="true">
    
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/struts-config.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/tiles-defs.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/validation.xml</WatchedResource>
</Context>I use this to set monitored resources that will trigger an automatic appliation reload and to configure JAAS (not shown). See the Tomcat documentation for additional information.
8. In the 'conf' directory I create a server.xml file used to configure Tomcat (you can copy the one from your <TOMCAT_HOME>/conf/server.xml).
After copying the file change appBase attribute in the host element to be the full path to the webapps directory. You can also change the HTTP and HTTPS ports if you wish
9. Download and install the Tomcat Launcher plugin from Sysdeo.
10. In Eclipse's Preferences menu you will see a new entry for Tomcat. Click this then
a. Set your Tomcat Version
b. Set your Tomcat Home
c. Set "Context declaration mode" to server.xml
d. Set the configuration file to the full path to your server.xml file created in step 8
On the "Advanced " sub page select all relevant projects to add to the Tomcat classpath
On the "JVM Settings" page add all the jars in your WEB-INF lib directory to the class path
On the "Source Path" page select all relevant projects
Now if you start Tomcat using the Tomcat icon, you will be able to remote debug your application. If you change web.xml (or any other file in your context.xml watched resources) it will automatically reload. Any changes to JSPs will automatically be picked up (providing your tell your browser not to use the page in cache - e.g. CTRL+F5 in IE)
There are some limitations that I'm still working on however. Primarily that I haven't included the Tomcat Manager application in my webapps directory, so Sysdeo cannot perform a reload. This means that if I change a source file, and eclipse auotmatically rebuilds, Tomcat doesn't pick up the change unless I either change a watched resource file (e.g. web.xml) or stop and restart Tomcat.
There's no reason why this can't be fixed, I just haven't got round to it yet.
I'm sure there are lots of other (probably better) ways of achieving the same thing. This was the first method I tried and it worked, so I stuck with it. I'm not a Tomcat config guru and I'm sure other forum users could provide some improvements should they wish.
Post if you get into trouble, however I won't be able to respond until next week.
Cheers,
Steve

How can I avoid a full scan when ...

Hello
How can I avoid a full scan with I apply the aggregate function "MIN"
SQL> select min(c1) from hh;
   MIN(C1)
         1
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE

The table 'hh' does not have statistics. Assuming that there is an index on the column c1, statistics are computed on the table and its indexes, you may see a
INDEX (FULL SCAN (MIN/MAX)) of the index on column 'c1'.

How can I avoid music playback stopping when starting an App

Whenever I listen to music on my iPAD3 and switch from the build in original musicplayer to any App, the music stops to play.
I need to go to the taskbar and go to the very left to press the play button again.
That helps me to use the App choosen before and listen to the music.
If I open another App or switch there with "sideswapping", music stops again.
How can I avoid this ?

Revit must be using the discrete graphics and possibly a fair amount of cpu as well. This has nothing to do with memory or memory allocation (which you can't do on a mac since it doesn't use shared memory like some low-end PCs do. Getting hot is not a problem as long as the fans speed up to increase the cooling. If the system is overheating, it will shut down on its own.

How can I avoid re starting weblogic when servlets change

Hello all,
I always re start weblogic server 6.1 upon any changes to class files or servlets. does any one know of any configuration settings to avoid a re start when ever my servlets or class files change ? I deployed the application in exploded format and not in .war file format.
thanks much
Srik.

Hi,
if your question is: how can I update changes in my WebApp without having to restart my Weblogic server, then I have a hint:
Maybe your server is running in productive mode. Try setting it to developement mode (edit the 'startWeblogic.cmd', find the line 'set STARTMODE=true' and change it to 'set STARTMODE=false').
After this change the server needn't be restarted to make changes take effect.
Hope this helps.
Thomas.

How can I include "sort name" column when burning a playlist to disc?

I noticed the "sort name" info is missing in the burnt disc. How can I preserve the info? I spent some times in correcting some sorting order in my library and I want that info to be in my backup too.

The sort fields should be getting stored in the files' tags, assuming they have tags. When buring an audio disc this information will be lost. It ought to be preserved when using the iTunes backup function, however you may be better off using a 3rd party backup tool to backup the entire iTunes folder.
N.b. You've posted in the Using iTunes for Windows forum but your sig says you're a Mac User, otherwise I'd recommned SyncToy 2.0 for your backup. I'm not familiar enough with Mac to suggest a suitable replacement.

How can I maximize video quality of SMplayer?

I use Smplayer and I was wondering whether there is some sort of recommended codec and/or setup for smplayer to maximize the quality of videos

smplayer uses mplayer for its engine so any quality/video codec things would be done through mplayer. i use mplayer-vdpau-nogui package, which has alpha/beta/whatever support mplayer has for vdpau (for nvidia cards primarily). i use the standard PKGBUILD with some omissions (the remote control, and other things i dont need). this package is also svn, so you get the latest trunk source. then use the pkgbuild for smplayer-svn to keep any changes smplayer made concurrent to the svn version of mplayer. i get successful builds usually every couple of weeks (though i only build it every couple of weeks, you can do it daily if you want).
then if you want more details on what you need, you can check out what codecs and such you can do by going into src and doing ./configure --help to see what options list the codecs available to build, and what libraries you would need for them.
the mplayer webpage can help you with the build options.

How can I avoid the blank mainFrame when frameset first opens

I am making up framesets to accomodate over 130 pages. When the frameset first opens, the right hand side, the mainFrame, is blank until you click the image on the left frame. Is there any way to avoid this and have content show in the mainFrame when the frameset starts up. Url is:

Why on Earth are you using FRAMES???! You don't need them. They only complicate your site by making it almost impossible for people to bookmark and print pages. HTML 5.0 no longer supports Framesets and here are a dozen other reasons to avoid FRAMES.

How can I avoid a pop-up when I'm going from an email to the email list?

I use Mozilla firefox to go online. When I've opened an email I've received and then want to return from that email to the email list, I click "backspace." Half the time, it gets me back to the email list. The other half the time, a window pops up, saying:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier" and I have to choose to cancel or resend. I always click resend. I don't want this window to pop-up. When I read an email and then hit the backspace key, I just want to get back to the email list.
Can you help? Thanks, Alvin Glazerman

Don't use backspace to go back to that page. Either open the link in a new tab with a middle-click and close that tab to go back or click a link to go back to the inbox if there is such a link on that page.

Quality Loss when Burning to DVD

Hello,
I have a DVD that we sell that has about 80 to 90 minutes of footage on it each week. We can barely fit it on a DVD and when we do it gets pixellated and the quality looks bad. Can someone please give me some advice on how to limit this problem? I see full Hollywood movies fit on 1 DVD all the time, am I doing something wrong?
Thanks!
Andy

Hi Andy,
I also use the HD2SD methods and get superior results, but that workflow is not for the faint of heart. Once you learn the workflow its not bad, but perhaps not the best solution for high-volume production.
Let's look closer at your current workflow. You should be able to get good quality using Adobe for that shorter program length (I often go up to 2.5 hours using HD2SD).
What is your source? If 1080i (interlaced), that can be problematic. Besides scaling the video to SD, the interlacing gets weird at the same time. HD is Upper field, DVD is typically lower field.
As mentioned in the thread, do NOT export to H.264 as an intermediate codec, no reason to. From the Premiere timeline, use EXPORT and choose "MPEG-2 DVD" and then an appropriate preset such as "NTSC DVD Widescreen". You should manually set the bit rate and this formula will help. 560/minutes = bitrate, and just round down a little for safety margin. 560/90=6.22 so go with 6.0 or 6.1 and should be fine, or for the 80 minutes maybe 6.9 rate.
Two-pass VBR will help provide a better encode than CBR. Try something like 3 min, 6 avg/target, and 8 max.
If using the 1080i source, you can manually try setting the fields to Upper for the encode and see if that helps. If encoding from 1080p, then of course choose a Progressive DVD preset (no fields).
At the bottom of the encoder window, there is a check box for "Max Render Quality", always use that when scaling the output, such as HD to SD.
Import the resulting .m2v and .wav files into Encore and author. The video should NOT get transcoded. With your workflow, were you bringing the H.264 HD file into Encore and letting Encore transcode? Premiere/AME is said to do a better job, don't let Encore do it for you.
Hope this helps

How can I change the song order when burning a CD?

I'm trying to burn about 20 songs to a CD. However they are in alphabetical order in the burn folder which I don't want. I want then in the original order they were performed. How do I re-order them before burning?
A related question: eventually I will add them to iTunes and I'll want to add info such as the artist's name, album name, etc (these were recorded live by me so they're "blank" audio files). Is there a way to add this info prior to importing into iTunes so I don't have to manually add the same info to each track?
Thanks in advance!

Here's what I ended up doing:
I took the blank songs and added them one-by-one as WAV files into iTunes. Then I modified the "get info" summaries and added the artist name and album name to each. But now I had these huge WAV files... too large to burn back to my iPod. So I created a playlist in iTunes for the 20 songs and then burned them to a CD. Then I deleted the songs from iTunes, then re-imported them from the CD.
Kind of convoluted, but it worked and didn't really take THAT long. I now have the songs on my iPod with all the artist info and a backup CD with the same info and as WAV files.

Hi 侠客
The Series2 error/arb capture register indicates where the last error happened. In this case, the bit stuffing rules (not more then five consecutive bits of the same state) where violated. Typical causes are:
Baudrate mismatch (most likely no commmunication at all possible)
Improper termination (please see chapter 4 of the NI-CAN Hardware and Software Manual for more information)
Wirering schema not compliant with the CAN specification (ISO 11898), e.g. stub/drop length too long, star-type setup instead of a chained setup
