Jagged edges using DVCPRO 50

yeesh.
We are capturing footage that was shot at 24 fps, 16:9 anamorphic standard def on an SDX900 camera using on DVCpro tapes, off of an AJSD93 deck over firewire. We capture with the DVCPRO50-NTSC codec, and have tried both 23.98 and 24.
and we are PLAGUED with these frames with horrible jagged edges. This appears to be an interlace/field dominance problem, but uh it was shot progressive. Any of you masters got any ideas?
below is the example frame

  • Aliasing issues in ACR 6.4 output, jagged edges

    In images with high frequency detail, aliasing occurs that is most visible in diagonal directions. These jagged edges are noticable in the output, and obviously get worse in enlargements which is also the main reason I post this.
    To date, I've found 2 workarounds:
    process in ACR, duplicate layer in Photoshop, apply gaussian blur around 0,5px, and manually paint on the offending jagged edges
    use another raw converter
    For demonstration purposes, I've taken an old and unspectacular D3X NEF from imaging-resource.com. It's a picture of a house and some trees etc. I've used:
    Camera Raw 6.4 with default settings (first row): aliased edges
    Capture One Pro 6.2 with default settings (middle row): anti-aliased edges but introduction of false (green) colour
    Raw Developer 1.9.1 with default settings (bottom row): anti-aliased edges free from artifacts
    Some (100%)  area's where the aliasing shows:
    At first I thought the difference was due to the sharpening in these 3 convertors. Forgive me if I omit showing a comparison and just assert that turning of sharpening and replacing it with Photoshop remove lens blur, didn't help. It just showed the defects apparantly already present in the (ACR and C1 processed) file.
    The result however from a properly sharpened, denoised, and upsampled TIFF that originates from Raw Developer is impressive. However, given the fact that Raw Developer is Apple OSX only, and I do post-processing on Windows, it introduces a bit of an unpracticality.
    Is there any possibility to eliminate this unpleasant aliasing in ACR, so I can keep a high quality Adobe-only workflow?

    The "blocky" details are easily reproduced in that image.  Looks like something that needs to be tuned up to me.
    Note that you have the option of choosing the 2003 process in Camera Raw, which appears to avoid that issue.
    I just want to add one thing:  There's no upsampled resolution available for this particular camera.  6048 x 4032 is the largest size available.  I for one prefer to convert my raw files directly to upsampled resolutions on the theory that it might improve this kind of thing (and it does seem to deliever more accurate detail with my now out-of-date Canon cameras).  At some point in the past I requested that Camera Raw make several upsampled resolutions available beyond the "native" camera size for any/all cameras.  I hereby renew that request.

  • The end of jagged edges in iMovie using stills

    It took an astonishing 14 months, but I have finally beaten the dreaded jagged edge quality issue in iMovie when using still photos. If you're reading this, you're a sufferer. How could the software be so bad as to ruin every picture you put in there? It's all about knowing the settings, and that can be difficult without some help.
    It feels as though I've really gone through the mill with this programme, but here's your fix - or at least, a fix that worked for me.
    Initially, I was using the first version of iMovie and the first version of OSX. In that environment I found the problem unsolvable. I didn't get anywhere until I upgraded to Panther (10.3.9) and iMovie HD 5.0.2. Here there are many more options and settings, but it is still a minefield. I tried almost every setting there is, and have the 'coasters' to prove it.
    My fix is for widescreen. Choose HDV720P. Select your frame rate in the preferences box at 25 (which is PAL for use in the UK) And that's it. It produces a stable, high quality movie where all the effects available work perfectly - and no jagged edges!
    If, as I do, you use Photo to Movie for more adventurous multiple pan and scans for sections of your movie, export from that software using 'higher quality' on rendering, select 16.9 widescreen, and DV stream PAL as your export format. This stops iMovie from trying to resample it, and very possibly giving a choppy or jerky movement to your imports. Using the above settings will give a perfect result, and you can freely use iMovie's transitions to join an imported item to footage created in iMovie.
    I've now produced many very successful movies on these settings. It works for me, I really hope it works for you. iMovie can drive you up the wall when it doesn't give the results you know it can be capable of.
    Quicksilver G4   Mac OS X (10.3.9)  

    Thanks for the idea, Steve. I like working with the HDV 720P high def projects for slideshows too. The quality is awfully nice to work with and it delivers projects that will work far better with tomorrow's hardware. Although we can't burn HD DVDs yet, hopefully that day will come soon, and the HDV slideshows we create today will look very good on the HDTVs we own tomorrow. They look good today, but they will look even better tomorrow.
    It should be noted, however, that it's not necessary to create an HDV project to avoid the jaggies on still images. The cause of the jaggies in DV projects -- the type of projects we mostly make -- is well known and can be avoided. It doesn't require third-party software like Photo to Movie, but it does require avoiding a bug.
    iMovie adds the jaggies after we press the Create iDVD Project button in the iDVD tab of iMovie. When that button is pressed, iMovie will ask permission to render any UN-rendered clips, including any unrendered KB images. If you grant permission to render, iMovie adds the jaggies while rendering those images.
    If the clips have been previously rendered by Ken Burns, or if you refuse permission to render after pressing the button so iDVD renders them later, you don't get the jaggies.
    I use Ken Burns to render images as they are imported, which it does with great quality. Once rendered, iMovie won't ask to render those images again. One reason I render with Ken Burns is so I can grant iMovie to render OTHER clips when it asks permission.
    Ken Burns will render the image if the KB checkbox is turned ON when the image is imported. So turning on the checkbox avoids the bug.
    If the checkbox isn't on when you import an image, you can select that KB clip in the timeline later, turn the checkbox ON, and Update the image.
    Regrettably, once iMovie has added jaggies to clips they cannot be repaired. It's necessary to re-import the image and discard the flawed clip.

  • I Reinstalled Premiere Pro CS3, loaded a project I edited using CS3, and NOW I get jagged edges!

    Hey everyone. I was using Premiere Pro CS3 to edit some footage I shot with my HPX170 in 1080i 24p Advanced. The P2 footage looked great in Premiere CS3. I upgraded to Premiere CS5, imported the same exact project into CS5 using the same 1080i 24p Advanced setting, and I got jagged stair stepping edges on the objects that were in sharp focus in my footage. Okay, I thought, I'll just reinstall Premiere Pro CS3 and continue editing the footage in CS3 since it looked normal in CS3 with no jagged edges. But, to my surprise, I'M GETTING THE SAME EXACT THING NOW IN PREMIERE PRO CS3!!!! What in the heck is up with that? How can the footage look normal when I imported and editied it before in CS3 and NOW I get jagged stair stepping edges?!!!! I even tried importing a fresh clip from the footage and that clip still has the jagged stair stepping edges. This makes no sense whatsoever! Does anyone know what's going on with this? It seems like an interlace artifact problem BUT, if that's the case, why didn't it do this the first time in Premiere Pro CS3? And trust me, I would have noticed right away if it did!

    Hey Shooternz. Which exact playback settings are you asking about? I set the one of the playback settings to "Highest Quality" instead of "Automatic" and nothing changed. I unchecked 24p Pulldown in the "Interpret Footage" section and nothing changed (I don't even remember "24p Pulldown" being in the Interpret Footage section the first time I installed CS3, which is strange. Was that added in an update?). I tried different sizes like HD 1.5, HD 16:9, etc. in the Interpret Footage section and the jaggies are still there. Nothing seems to work. ??? This is weird because they weren't there the first time I edited the footage in CS3 when I installed CS3 the first time. One thing I noticed is, when I installed CS3 the second time and loaded the project, as the project was loading, I got a message that said something like "These project settings cannot be loaded. We will now switch to Desktop Mode." Would that have something to do with it you think?

  • Jagged edges on vector art and fonts on R1900 using AI CS5 in OSX

    OS 10.6.4 (Mac Pro 2x2.4 GHz Quad-Core Intel Xeon, 12GB ram 1066 MHz DDR3)
    Problem with the R1900 Printer and AI CS5
    I have been using the same printer with CS4 without any trouble whatsoever for at least 5yrs. Beautiful quality prints without so much as itch and great color control...
    In October I finally made the switch to CS5 and my printing capability goes to hell.
    Quality printing straight from AI to a non-postcript inkjet printer such as the R1900 doesn't seem to be an option anymore...
    I get jagged edges on vector art and fonts. I do graphic arts/logos/prints and this is a huge issue...!
    Apparently I have to save my AI files as PDFs and print from there, but this poses extra steps, troubles in sizing, colors, page set up...
    I mean nothing beats being able to print direct from AI... I cannot understand what the problem is all of a sudden.
    At home I have a late '06 Mac Pro running CS4 and printing successfully to a C88 epson inkjet printer under OSX 10.5
    What is the matter, please help, this is cramping my style and performance???
    thank you

    Ok this would not be a problem with 10.4.11 on a Power PV Mac but on an Intel Mac running 10.6.4 or running anything above 10.4.11 on any Mac you would need a postscript driver. Problem, there is no postscript driver for this model Printer this is actually a photo quality printer, that is what it does best.
    So what to do the best one can do is to save the file as a pdf and print from Acrobat. There is no other way regardless of what one would like and expect.

  • Jagged Edges - When compressing 50 minute clip - burned in DVDSP

    I'm in the process of authoring four DVD's (mixed martial arts, muy thai etc) which was shot in HD on a Panasonic HVX-200 using the DVCPro HD codec, at 24 fps progressive.
    2 of the four DVD's I'm having problems with jagged edges around the two fighters (two guys shot against a white backdrop), you can clearly see blocky artifacting around the edges of them.
    I've tried exporting via compressor using a 1-pass VBR 6.2 Mbps min - 7.7 Mpbs max, imported into DVDSP, build the project, and then when I use the DVD player program, I can see the artifacting.
    However, I have a couple of other clips on the DVD, that were exported the exact same way, and no artifacting is evident.
    I tried re-encoding at a CBR of 7.7 Mpbs, no change. Any ideas?
    One thing that I just thought of is that I have been using the same source folder when building the project as the previous versions (to save time rebuilding all the motion menus, etc). Could that be a reason? Would DVDSP be using some of the information from the older encoded video?
    Any thoughts please.

    Make sure that you are encoding for 24p. Set the video format for 720p, and the frame rate for 23.98. You should also be using 2-pass VBR, not 1-pass.

  • How do I get rid of jagged edges in Photoshop?

    Can someone tell me how to get rid of jagged edges in Photoshop?  I've tried using the refine tool and checking the anti-aliasing/smooth option, but neither appears to work. Here is the problem.  I use Photoshop to create the images for heat transfers that I press on to T Shirts. In transparent mode, I cannot see the edges, nor can I see them once the transfer has been printed, but when I press the image on to a T-shirt the edges are extremely jagged.  Also, when I add a solid blue background in Photoshop, I can see the edges.  I am using the TW Cen MT Condensed Extra Bold font (140.13 pt). 
    Additional Questions:
    Are there fonts that inherently behave this way when stretched?
    Are there fonts that hold up more consistently when stretched?
    Will rasterizing the image resolve this problem, or at least give me a higher quality image when stretched?
    Is there a way of using inches instead of points for font size and if so, where do I change it?
    Is there anyone out there who uses Photoshop to create text and images for T-Shirts? If you have the answer to any of my questions, please respond ASAP.  It is extremely important that I be able to get consistent results clean, smooth images that transfer well onto fabric. I am attaching my text image on transparent background, as wells as a solid blue background.  You may have to zoom in on the gold and black image to see the jagged edges on the fabric.

    You have AA set to None in the Options bar is my guess.  Use whatever option looks best, but never use None.

  • Images imported from QT exported image sequence have jagged edges

    Hi
    I've come across something strange which I'd like to resolve.
    I export an image sequence from QuickTime.
    I then import this into Aperture.
    But the images imported into Aperture now have jagged edges where there has been any movement in the original footage.
    The images originally exported from QuickTime look absolutely fine when viewed with preview, they have the expected blurring on moving objects, but no jaggedness.
    Now, a bit more detail.
    The footage I'm exporting from was shot by me and came from a Final Cut Pro edit.
    The codec in the QT movie is Apple Intermediate Codec and this is interlaced.
    The jagged edges on movement look to me like the problem of interlaced not being converted to progressive.
    However the exported images from QuickTime don't display this when viewed in Preview, it is only when viewed in Aperture that the jagged edges become apparent.
    I have tried exporting from QuickTime to jpg, png and psd, but the problem is identical no matter which format I use.
    I really want to now use Aperture to improve these exported images, but with this jagged edge problem I can't.

    Hi JNorris--
    Sounds like you need to apply the deinterlace filter (Effects tab: video filters: video: deinterlace) to the stills your exporting.
    See if that makes a difference to start.

  • Saving Shapes to PNG Causes Jagged Edges

    Hello,
    I use a Mac and I have Illustrator CS6 and I've noticed something strange. I create shapes using the pentool. When I save the shape to a PNG with a transparent background, it looks smooth, however when I import and resize the shape it pixelates and it has jagged edges.  I've attached a screenshot so you can see what I mean.
    I'm wondering if it's a setting or something that I don't have turned on (or off).  Or perhaps it's something else.  I'm curious why this is happening.  I’ve turned on the Anit-aliased Artwork and changed the ppi to 300…but to no avail.
    Any help would be appreciated…but I’m new to Illustrator and have no idea, so please use detailed and basic instructions that a noob can understand. 
    Thanks in advance.

    You answered your own question. A png is a raster image therefore resizing the image will pixelate it.

  • Jagged Edges after rotating a stroked image

    I've have this problem a lot but I guess I'm just now getting around to ask about it.
    When I have a  photo in cs2-cs3-cs4 etc and I rotate it at an angle I get fine jagged edges all along the sides. It's becomes very pronounced in a stroked image even when I I stroke the image after rotation. The problem is more obvious when the image is not at angles like 45 or 90 degrees but more visible at in between angles.
    Any suggestions?

    What you are seeing is alaising, and it is inherent in raster graphics when the line to be shown is not parallel to the columns or rows of the image.It can be mitigated to some extent by antialaising, which softens the edges of the diagonal lines. When you select all of an image and stroke for a border, antialaising is used. With the polygonal lasso tool, you can turn antialaising on or off. Alaising is less apparent with very high resolution, but it can't be elilminated.
    Here are triangular selections with antialaising turned on and off:

  • Jpg jagged edges

    Hi,
    I'm making a video from jpgs -- all were taken by a professional photographer, really big file sizes, so that they are down to about 26% to fill the screen. Problem is the jagged edges, particularly on straight lines -- and there are a lot of these because it's architectural photography.
    Tried Gaussian Blur in FCP, but it softens the photos too much.
    Any other ideas?
    thanks,
    Eve

    Let's try this from the top.
    Recognize that NOTHING on the TV will ever ever look as sharp and as detailed as the original images.
    1. A pro photographer should be able to deliver files in TIF or PSD - lossless formats. JPG is a lossy format designed to compress images for transmission over the internet and display on computer monitors. It was intended to be used by people who care more about small file size than maintaining image fidelity.
    2. Unless you are doing moves (pan/zoom) on the images, you should reduce their pixel count to something close to the codec size. For DV, the equivalent square pixel size is 720x540. Best to do this in Photoshop (or other image editing software) before importing into FCP as FCP does not have the most sophisticated scaling engine.
    3. Deinterlacing still images makes no sense what so ever. Deinterlacing takes half the image and throws it away then adds back the missing lines of information interpolated from the remaining lines. Why would you do this on a still image?
    4. Images with a great deal of contrast and or thin horizontal edge detail will benefit from a slight vertical gausian blur - .5. This will make the detail that exists on only one scan line (which may appear to vibrate) blend over two scan lines so the image will counterintuitively look sharper - or at least more stable. Setting the Field dominance to "none" will also help as it tells FCP to render by frame not by field.
    5. Keep in mind the color space of the DVD is the same as DV - 4:1:1. Unless you are manipulating the images (color correcting, composting, overlay titling, etc) your images will not improve with ProRes or DV50 codecs and the editing file sizes will grow significantly. If you are engaging in those activities, you will see a benefit.
    6. Unless you are planning to make some variant of an high definition DVD (currently Blu-ray), it doesn't make any sense to me to work in an HD format for editing then down convert to DV size for burning. Why not simply work at the size/aspect ratio of the final output?
    7. As noted, you really MUST have a TV monitor connected to view the material as you edit/play it back. Otherwise, you will have no idea how your work will display without burning to disk.
    Have fun.

  • Jagged Edges

    Hello,
    First of all, forgive me but I am a complete newbie who's new to the world of Final Cut and video editing.
    Here's my problem: I captured a bunch of footage from a Sony consumer video camera. But when I look at it in quick time and on final cut, the footage has a lot of jagged edges, specifically when the camera moves.
    Did I do something wrong when I captured the footage? Is there a way to clean this up?
    I'm using FINAL CUT PRO 5.1.
    Any info would be greatly appreciated.

    You are in all likelyhood seeing interlacing which does not display correctly on computer monitors.
    What format does the camera shoot? If you are unsure, post manufacturer and model information.
    The next step is to make sure that FCP is set up correctly for the camera's format.
    Even then, you will still see interlacing, it is a normal aspect of many video formats that are designed to be viewed on a television screen.

  • Can't get rid of jagged edges of aligned objects

    I have the annoying problem of jagged edges on aligned objects in Illustrator. This image demonstrates it well: http://i.imgur.com/AIyK6vK.png
    You can see the white background shining through where objects align to each other. I thought this was only a display thing which wouldn't show up on print or export, but I get the same aweful results when exporting to png, pasting as a smart object in PS etc. How do I fix this?
    Thanks!

    I've tried that aswell and it looks a bit better, but that isn't always (never?) a good solution.
    Jacob, I've had no luck with the other thread, I was already using smart guides. This is a strange problem. I've not seen a lot about this anywhere else, don't you guys have this issue?
    There is one better solution than a background layer. Select all objects and offset the path buy a very small number, maybe 0,01 mm but that is also more of a "hack" than a real solution..

  • Jagged edges on text

    My text has jagged edges after I render in FCP 4.5. This also happens when I import files from After Effects and Live Type. I recently lost all of my sequence and render settings, so my thinking is that it's one of those settings. Any ideas?

    By default FCP sequences are in the DV codec which looks as if it loses resolution when viewed on a computer monitor. If you're outputting your video to an NTSC monitor via firewire, DV should look fine ... you must be looking in the Canvas.
    (DV doesn't really lose much resolution on computers ... if you open a DV video file in Quicktime & go to Movie Properties-->Video Properties, you can select "High Quality." The Powers That Be at Apple so ordained this setup because computers used to have trouble playing back full-resolution video at 29.97 fps ... not really the case nowadays but they keep playing DV at "low quality" by default.)
    If you change your sequence codec to Animation it will look sharp & crisp. But be careful, Animation files will eat up space on your scratch disk like CA-RAAAAAAZY. So either you need oodles of space or short animations.

  • Shapes get random jagged edges

    Hello,
    I am working on a freelance logo and the client kept mentioning that my sample PDF's seem to have "smudge" on part of it, I never saw it and then I asked them to actaully SEND me the file while I was not at my primary computer so I can look at it.
    It is really wierd.  It seem that when you zoom in and out the shape changes and gets these ramdom jagged edges.  I don't see them on my computer or phone and my client only sees them on her desktops but it does also print out with these wierd edges as well.  I converted all type to lines and did an export to PDF to show her samples.  I have attached photo expamples.  Please help! i have never had this before.  The first image shows how it is supposed to look and how it did look when I first opened, the other 2 show what happens when it gets zoomed.  And it changes too, it isn't the same jagged edges everytime.
    Thanks!

    In IIllustrator, you woudl normally chaneg your limit (AKA miter limit, flatness) to a lower number
    Since this is happening in acrobat, you may be able to fix this with your preview settings. Problem with that is your clietn would also have to change their settings. The ones under rendering is what you want to change.
    If thsi dont help. you want to look at where tehis is happening and if you have overlapping vector points, would be good to clena that up. You also could jsut use object >> path >> outline stroke, to get rid of stroke, so that acorabt is nto tryign to render them (whcih goes back to the beigginng of my post as I belive the pdf rendering of miter limits is at play here - no stroked paths,  no miter limits).
