Is There A Quick And Easy Way Of Avoiding "Stepped" Edges (Aliasing)?

I am using Compresor 3.0.3 to encode HDV projects to SD DVD.
I originally tried Exporting QuickTime Movies from FCP but discovered there was terrible shimmering on straight edges and severe judder when panning or if someone walked across the frame.
Using the "DVD Best Quality 90 minutes" setting smoothed out all the above problems.
Unfortunately it left noticeable stepping or aliasing on diagonal sharp lines !
This is much less of a problem than the judder but if possible I would like to get rid of it.
I have read up about the Bonsai method, but the processing times involved are enormous and not warranted by the slightness of the problem.
I have also seen an anti-alias slider in Compressor but when I used it the processing slowed almost to a halt. Maybe I was operating it incorrectly ?
Is there a quick way to get rid of the stepped edges, or is it something everyone has to live with when converting HDV to SD DVD ?

Yes it's all PAL Kyle. The problem isn't just mine though. It seems to be par for the course. From what I have read, the Bonsai method was devised to overcome it but the actual problem is really so slight, that for amateur work the cure is a bit over the top.

It's too darned hot Luca ! Especially at night.
Your process seems a bit like the Bonsai method and I'm beginning to think that I might be exaggerating the problem in my mind.
The aggravating thing is that when I did a straight Export>To QT Movie, although I got terrible judder, there was almost no sign of aliasing ......... which is why I felt there should be a simple solution.
I'll just have to pray that they bring the prices of Blu-ray down rapidly, so there will be no need to use standard def.
I am going to experiment with shooting 25PF tomorrow to see if that helps ........ or not.

  • Is there a quick and easy way to reorder de-interleaved data?

    I am collecting 5 channels of data through a DMA FIFO by interleaving, then recording to a TDMS file. When I check it, it's in mostly good order, but there are certain points where the channels get switched. For example, the Channel order when I open the file is 1 2 3 4 5, as expected, for several thousand elements. But at some point, it gets shifted to 4 5 1 2 3, and later 2 3 4 5 1. Left-to-right, they are always ordered correctly, so it's easy to reorder them, but very tedious with millions of elements. I have attached some sample data. I'm looking for A) a way to prevent this or B) some kind of sorting tool or script in LabVIEW or DIAdem that may sort it for me. I'll work on a sorting script in the meantime. 
    I am using LabVIEW 2011 Real-time and FPGA 2011, and the standard TDMS open and write functions. I also have access to DIAdem. 
    Solved!

    Sorry for the slow response - 
    I've looked at everything, and so far I can't identify the problem. I believe my code is consistent with the producer-consumer architecture. 
    On the real-time side, I am reading data from the FIFO and writing to the TDMS in the same loop.
    On the FPGA side, analog channels are read, converted to the same fixed-point format with a time stamp in a single-cycle timed loop, and then ordered into the FIFO in a for loop. I have posted the relevant parts below.
    I am using C-series modules in a CompactRIO.

  • Is there any quick and dirty way to determine what something will look like

    Hi,
    Is there any way (rule of thumb) to determine what something will look like when printed.
    for example.
    I am doing a composite (hope this is the right word). It will have some people sitting at a table and I want to have another layer with another picture behind it.
    I plan for the output to be fairly small (print size), say 4 x 5 or whatever.
    Now, if I go to the internet and google (or mamma.com) and search for images (large) and it comes back to me, I will see pictures that are (for example) 800 x 526 pixels 367 kb, or 940 x 480 pixels 166 kb.
    I would have to assume the 367 kb will print at better resolution, but if i liked the 166 kb picture better, is there a quick and dirty way to determine if it would print better (say 250 or 300 dpi or whatever) or not?
    So, bottome line,
    Assume my output picture will be 4 x 5 (and I want 300dpi (or is it ppi)
    How do quickly look at google results and determing if they will print ok?

    The closest to a one click fix in photoshop cs-cs5 is
    Image>Adjustments>Shadow/Highlight or opening the
    image through camera raw and using the recovery slider.

  • Quick and easy way to learn to use Oracle Spatial?

    Could anyone recommend a quick and easy way to learn to use Oracle Spatial?

    Depends on your style.
    Reminds me of a story a contractor to an IT department I worked in once told me.
    He used to work in Silicon Valley in the '70s and told a story of a company that
    hired a particular programmer who was brilliant but unstable. They used to set
    up a room with a VT100 and a bottle of Tequila. The programmer would arrive
    and set to work. As the Tequila emptied it was replaced. At some point over
    the following days or weeks a scream would be heard from the room, followed
    by a crash as the VT100 went through the window and the programmer disappeared.
    They would replace the window, the VT100, the Tequila and wait till he came back
    from "walkabout".
    "Extreme Programming" '70s tyle!
    OH&S would never allow this nowadays! That, plus Prozac means these sorts
    of programmers are probably very rare!
    Cheers!

  • Quick and easy way to encode video files?

    With out using another application.

    An easy and simple way you can do this is by using Finder. It might not be the best option, depending on what you need but try it out.
    Control+Click on the file and select > Encode Selected Video Files
    You can choose from 480p, 720p, 1080p, Audio Only, or  Apple ProRes under the Settings drop down menu.
    Then choose whether you want to Encode for higher quality or greater compatability.
    When you have selected your settings the window will tell you the Format, Resolution, Date rate and what it compatible with. The 480p, 720p and 1080p will use H.264 compression which is highly compressed and probably what you want to choose to compress your file.
    After you have selected your settings select the destionation and if you want to delete the source file and click continue.
    Done. Easy and simple, done right in finder.

  • A quick and easy way to add genre to songs in a playlist

    I have a 160mb classic ipod and I want to shuffle only a portion of my total library tracks. I am thinking the best way to do this is to use the Smart Playlist function and shuffle by genre. But if I do that I want to change the genre label or add one to many of my 4000 songs. Is there anyway to do this easily? I tried to select every song in a playlist and right click and use Apply Sort Field, but unfortunately genre is not one of these fields! Any idea?
    Or (although this may be the wrong forum), is the any way, short of making one gigantic playlist, to get my iPod to shuffle among just certain playlists?

    The only way to add to files to a playlist on the player itself is to put them in the queue, then save the queue as a playlist.

  • My computer had a virus and had to be cleaned, but I had my Mozilla bookmarks in a Word file now located on my Desktop. There should be an easy way to drag the bookmarks to the new Mozilla. Can you tell me how in simple straightforward steps? Thanks.

    Question
    My computer had a virus and had to be cleaned, but I had my Mozilla bookmarks in a Word file now located on my Desktop. I have spent hours trying to drag those bookmarks to the new Mozilla. There should be an easy way to do this. Can you tell me how in simple straightforward steps? Thanks.

    If the Word file is a document file type (.doc), you may be able to save it as a .html file, then import that .html file into Firefox.
    In Word, open the .doc file containing the Bookmarks,
    *click File > Save As,
    *in the "Save in" box, choose a Folder or location on your hard drive to save the file where you can find it later,
    *in the "Save type as" box choose ".html",
    *in the "Filename box" enter "bookmarks.html" (without the quotation marks),
    *click "Save"
    Then follow the-edmeister's instruction in Firefox:
    *Bookmarks > Organize Bookmarks -> Import & Backup - Import HTML... = from an HTML file
    *See: http://support.mozilla.com/en-US/kb/Importing%20Bookmarks%20from%20an%20HTML%20File

  • E1200 and "Quick and Easy Setup"

    My parents were trying to setup their E1200 router. We had to do a reset (using the button) since we couldn't access the router admin menu (someone had hacked/changed the password). I'm doing this remotely over the phone.
    Now, when they open Internet Explorer, they are getting a"Linksys Quick and Easy Setup" screen no matter what web site they try to get to. They don't have access to the original CD to install Linksys Connect. Mom says that when she clicks on "No CD? Download the software" link, nothing happens. Looks like she's got internet, though, as there's a link to the Linksys forums, and she's seeing updates from the forums."
    I don't know what this screen looks like, but isn't there some way to get past this splash screen? The computer is plugged into the router via a cable, so I'm not sure why they can't access the internet manually. Is there a way to just "disable" the "Quick and Very So Not Easy Setup" and skip right to using the internet?
    Thanks.

    Hi dapupster. I suggest that you let your parents do another reset. Tell them to make sure that they press down the reset button that's underneath the device ( please check the  picture). Let them press it down for 30 seconds while the device is powered on.  Once done, let them unplug the unit, plug it back in and try to access the setup page manually through 192.168.1.1.
    If the challenge remains the same, let them unplug the router from the modem and have them access the 192.168.1.1 page with only the computer that's connected to the router.  Hope the suggestions help.

    Why do we have to activate individually all third party apps!!! There should be as easier way! Apple TV is not Apple anymore...

    Primarily because those third party apps are just that, they are not Apple apps, and each have their own requirements for activation.

  • Is It Possible to Clone RAID Array in a Safe and Easy Way?

    Why do computer users need to clone RAID array, especially Windows Server users need to do RAID cloning? Generally speaking, they need to clone RAID array regularly in order to upgrade disk or migrate data from small disk to a larger one. A typical
    example is that when the partitions on the hardware RAID runs out of space, you may prefer to rebuild the hardware RAID with larger hard disks. Then, you need to backup the data to another place, rebuild the hardware RAID and restore data again.
    What a time-consuming task!
    Is it possible to clone RAID array in a safe and easy way? The answer is yes and this article will introduce a RAID cloning software.

    Hi jiangchunli,
    Were you looking to post this question in some other forum? This looks like related to RAID and Disk upgrades.
    This forum is meant for

  • HT1386 simple and easy way to sync my contacts from iPhone 3gs to Macbook Pro that both my partner and I use. Have tried with photos and and only 350 of 3,500 items have synced. Remember simple and easy, I'm still learning-slowly.

    Simple and EASY way to sync contacts from 3gs iPhone to MacBook Pro. Partner and I both use macBook. I have tried and get a message that only 350 of 3,500 item have syncd- all photos. I'm still learning and am very afraid of doing something that will wipe out all info,contacts and photos. Entering this site, the account shows my partners name, but accepts my other information.

    First of all, you should always save you photos on computer like any other digital camera.
    Backup on iCloud or iTunes only backup your Camera Roll. The other photos should be already on the computer.
    Note: Photos are not saved in iTunes, it's only a conduit between your iPhone and your photo managing software on computer.
    What computer do you have?

  • Updating 3GS from 3.1.2 to 6.1.3 taking way too long. Is there a better and faster way?

    How long does it take to update an original 3GS to 6.1.3? I followed the iTune instructions and it has been updating for hours already. Is there a better and faster way to do this?

    SO if I want to represent the London Underground
    network as a Graph how would I be able to do it?By writing classes of your own or using some one else's. I don't think that the collections framework has out-of-the-box support for graphs.... So try google first.
    The implementation details depend on the API you are going to use, of course...
    from A to B 5 min
    from B to C 4 min
    from A to C 9 min
    this information is redundant, the third info should be omitted. <nit-picking>
    No it's not - What if there's a special, more direct route from A to C? Also, getting from A to B to C will usually take more time than the time from A to B plus the time from B to C. The trains have to stop at B, don't they?
    </nit-picking>
    Maybe this approach is more complex, but it solves the problem Have I understood correctly - isn't what you describe just another way to implement a graph?

  • I have what is hopefully a quick and easy question. I kno...

    I have what is hopefully a quick and easy question. I know almost nothing about this stuff so go easy on me . All I need to do is find out if my DHCP is enabled. I'm having problems with my Xbox 360 and one of the possible problems is this DHCP thing. However I have no idea how to find the settings for my router on my computer. If it helps I have a Wirless model BEFW11S4. Thanks in advance for any help.

    You need to access your router to check if the DHCP is on.  To access the router open your browser and type in http://192.168.1.1 into the address field and hit enter.  That should open the routers log on screen and by default the user is left blank (some routers it is admin) and the password is abmin.  If you changed your routers password as you should for security reasons then use that password.  That will bring you to your routers user interface and on the main set up page should be your DHCP.
