Interlacing issue

Hi there I was hoping to get some help on what may be a streaming/compression issue. I'm doing online videos with a Canon Legria HF M41 which is CMOS and not truly progressive.
They're basically guitar lessons and while they appear fine through iMovie and Quicktime and also on my You Tube channel, the strings appear broken, jagged, artifacty, dashed i.e. not right in other words, when I stream them from the server (Blue Host ) through to Acrobat X Pro documents. The size and quantity require streaming and not embedding.
I'm using iMovie (with Quicktime Pro export options) and exporting using Movie to Quicktime Movie.
The Options.. settings i've got are as follows :
Compression: H.264
Quality : High
Frame Rate: 30
Bite Rate: 128kbits/sec
Encoding mode: multi-pass
Dimensions: 960 + 540 (Current)
Deinterlace Source Video = Clicked on
The Prepare for Internet Streaming box is clicked and Fast Start is selected.
The Data Rate : automatic
Optimised for : Download.
I'm wondering if it should be set to Optimised for : Streaming . With some adjustments in the kbits/sec box ?
I think the problem seems to lie somewhere between my compression settings and Acrobat X Pro  or do I need to be thinking about a video camera update.
Any help would be appreciated.

You are seeing interlacing because you shot in 24P. 3:2 pulldown frames are normal. Until you send it to an external TV/Monitor, you cannot judge the output.
You REALLY REALLY REALLY should hook up a TV/Monitor it is not that hard. If you have a camera, you can do it. If you have a deck or an A-D converter you can do it. Going from zero and buying new parts, you should be able to add it for less than $350.

  • Interlacing issue when zooming in on photo in FCP

    Can anyone tell me why this image (picture 1) looks interlaced in FCP's Canvas window and on my NTSC broadcast monitor when in fact it isn't?
    I scanned this image at 600dpi planning to zoom in on the photo in FCP, so I know it's not a low resolution issue.
    In FCP, when I zoom in on the image it looks totally interlaced:
    Please see picture 1 (interlacing issue) here in my web gallery and compare with Picture 2.

    I have no idea what's causing this. Any help would be much appreciated.
    Thank you in advance,

    PS: I'm working in an NTSC DV sequence.

    Hi David,
    Thank you very much for your help. Yes, I did render the timeline. Nothing in the sequence was left unrendered. Is the problem that my resolution is too high? Should I diminish the size of the still by 50%?
    Picture 1 was scanned using "descreen" filter and picture 2 using Auto Tone only. I used a Canoscan Cannon 8800F scanner. That's as much as I know. I wonder if I did something wrong scanning the image or is there something I should have done in Photoshop prior to bring the still into FCP?
    Did you notice the horizontal line issue in Picture 1? I'm not sure how to describe it, but Picture 1 looks to me like there some interlacing issue going on.

  • Export sequence of still images (JPGs, TIFFs) from FCP timeline into DVD without interlaced issues using Compressor

    Hi,
    How to export a sequence with stills (jpg) into a DVD format by using Compressor without having the interlaced issue on the outcome? The stills in the Canvas look crisp but once exported to DVD format, the outcome images look interlaced. How can I best match the crisp look of the high resolution JPGs in time line when exported to DVD?
    My Sequence settings match the image settings:
    Frame Size: 1024 x 768
    Pixel Aspect Ratio: Square
    Field Dominance: None
    Compressor: Photo JPG
    I tried to export the sequence of img as an independent QT movie file by using Apple ProRes 422 output settings. The video file looks great. I then imported it back to time line into new sequence and exported into DVD format trying both: deinterlace and "same as source" setting. Both output DVD files still have the interlaced issue.
    I also tried to work with JPGs converted to TIFFs on a different sequence with same as Tiff settings and the issue still persists.
    I will appreciate any advices.
    Thank you,
    Izabela

    Dear Nick,
    Thank you, I understand now it is the aspect ratio issue.
    Are you suggesting that I should use Photoshop or Graphic Converter to convert the 1024 x 768 to 720 x 480 prior to importing them into FCP seqence?
    > Give the DVD authoring software the correct size:
    I am using FCP 7.0.3 to create the sequence of images (there has to be specific timing and transitions), which I then export to DVD format by using Compressor.
    Do you mean that I should set the FCP timeline sequnece settings to 720 x 480?
    Please let me know. Thank you,
    Izabela

  • Plasma Screen OK to test interlacing issues?

    Having interlacing issues with my 24P footage and IMac monitor. If I output to my plasma screen, is this the same as any NTSC monitor in regard to checking/monitoring interlace issues?

    Just to aid in the direction you're taking this.
    This is an extract from the "Key Features" of the Panasonic standard definition video camera I'm assuming he's been using based on his profile:
    Panasonic AG-DVX100B 3CCD 24p/30p/60i Mini-DV Camcorder
    • You may choose from three shooting modes: 24p (24 fps, progressive) for images with the look and motion of film movies, 30p (30 fps, progressive), or standard 60i (60 fps, interlace).
    • 24p Advance Mode For 24p Non-Linear Editing
    In 24p mode, images from the CCD can be 2:3 pulldown-converted (24p Mode) or 2:3:3:2 pulldown-converted (24p Advance Mode) and recorded onto tape in the standard 60i TV format. The tape can then be played back or edited using an ordinary DV system. True 24p editing can be achieved by uploading 2:3:3:2 pulldown-converted images via an IEEE 1394 DV interface to a compatible non-linear editing system. The 24p Advance Mode allows 60i/24p conversion with minimal picture degradation and on the fly 24 frame extraction.

  • Kona capture card interlacing issues

    Anyone have interlacing issues when capturing with a AJA Kona card. I see small horizontal lines when pausing the action and when there's alot of movement (hand waving, mouth moving etc).

    What sort of footage are you capturing? There are interlaced tape formats...LOTS of them. When you pause, yes, you will see interlaced lines.
    And are you looking at this footage on an external monitor?

  • Interlacing Issue - DV PAL to Uncompressed**

    Hi there,
    Please forgive me if this has been covered previously.
    I have read the "Sending back to FCP from Color**" post, but it's a slightly different problem I have.
    Original FCP timeline is DV PAL Lower Field. Used the Send To Color command and graded. I render out of Color at 10 Bit Uncompressed.
    In FCP I change the (from Color) timeline to 10 Bit Uncompressed (Upper Field therefore). So I have Upper Field 10 Bit clips in and Upper Field 10 Bit timeline; no green, yellow or red bars...
    But the footage is all jittery when playing back on the broadcast monitor. And no changing of the field settings seems to fix anything.
    The only fix is to apply a "Shift Field" plugin, and then it plays back perfectly... So it's definately an interlace issue.
    Is anyone else having the same issues ? What am I doing wrong ?
    Thanks in advance for your help.
    ps.
    Original timeline sent to Color was 16.9 Anamorphic

    COLOR 1.0, or as it could be referred to: "Final Touch 2.8", seems to prefer progressive streams. Interlacing has been a headache for a long time. The ColorFX room is especially a chamber of horrors.
    FT was designed, from the ground up, to grade sequential dpx/cin files. But consumers demanded a Quicktime HD solution. Does that help explain a few things?
    If you're aiming for a 10-bit finish...from 8 bit material-- I know it baffles most engineers how so many people expect to get more colour resolution that way, when it never existed in the first place -- you only get so many rungs on a stepladder no matter how closely you try to space them out-- maybe going into COLOR 10-bit would be a better approach than trying to push it up within the app. The sad stories about trying to leverage the render into another codec are legion.

  • Interlacing issues when authoring a DVD (PE9)

    I have a project on Elements 9 that needs to be put on a DVD, and while I did this before with some success, I am now faced with an output DVD with serious interlacing effects. It shows up on pretty much anything that moves, as shown in this image.
    The source video is 1024p at 59.94fps imported as MTS files, and I am trying to burn onto a DVD-RW disc. I have been looking for a solution to no avail, but I will continue searching the forums as this is a somewhat urgent problem. Any help would be appreciated.
    Here are my project settings:
    Capture format: HDV
    Optimize stills
    I have set everything to NTSC since this is a Japanese camera and I assume the video is as such. I'm not sure what other information to give, but please let me know if I should include anything else.

    Yes, the video is from a DSLR - not sure what qualifies as "high-end", but in my opinion the video is good quality: http://www.panasonic.co.uk/html/en_GB/2129937/index.html
    As far as the reviews are concerned, the 1080i has some noticeable interlacing issues, but the 720p looks nice.
    I tried burning this straight to DVD through PE9, and I also simply made a DVD folder and tested that. Both were of the same poor quality. As I don't own a TV I can't test it on anything else, but I'm fairly certain that this is not an issue with the playback software (which, in my case, is VLC). This will eventually be presented on a digital projector which at this point in time I can't test the DVD on until shortly before this is made public. Going to bet on the safe side and assume that if it looks bad on my PC then it will look bad everywhere else. (my future prospects with this company are on the line, I should mention)
    Since I'm in a bit of a rush (weekend deadline) I've come up with the (hopefully temporary) solution of creating an mpeg, turning that into an ISO and burning that onto a DVD. It adds an unnecessary step in the conversion process, but at this point in terms of quality it is the better option, hands-down. Still looking for a way to burn straight from PE9 to DVD since I do notice a slight resulting choppiness with the mpeg route.

  • Interlacing issues PLEASE HELP

    I've cut together a sequence using material I've ripped from a multitude of store-bought DVDs (the project is strictly for personal use only and will not be distributed).
    Though the sequence played down fine throughout the entire editing process on my computer, when I created a DVD (using DVDSP 4) and watched it on a set-top player, certain clips would stutter and sort of tremble, particularly where lateral movement was involved. I am confident that this is due to the fact that my source footage must have varying field dominance.
    Is there any way to correct this other than using a de-interlace filter which will further degrade the image quality?
    The details of my process are as follows:
    I ripped my source media using a shareware program called MacTheRipper, which allowed me to demux the DVD streams and get the individual AC3 and M2V files.
    Then I used Compressor (2.0.1) to transcode the M2V files to DV NTSC and imported them into FCP-3.
    Once editing was complete, I exported the sequence as a self-contained movie file using current settings (FCP-3 does not permit exporting directly to compressor).
    THE SELF-CONTAINED MOVIE FILE PLAYS DOWN FINE. Once I use Compressor to create an M2V file, however, the interlacing issues become apparent.
    Thanks in advance for your help.

    Was all of the footage in your sequence shot with the same camera? With the same settings?
    In my project, the problem is occurring because the various clips in my sequence were created with different specs. This is why I am seeing it sporadically throughout. Or so I think.
    The De-interlace option is simply a video filter that gives you solid, non-interlaced frames by erasing one field from each frame and interpolating what the now missing information should be. As I understand it, this is used primarily for material that is to be exhibited on the computer. Interlaced media looks pretty bad on a computer monitor, but it's appropriate for a television screen. If you're going to DVD, it's not a good idea to use it.

    I think David means put the actual bought DVD in. Talk about it. Put the next DVD in, talk about it. Put the next DVD in, talk about it. This is how I was shown various things. I remember seeing several showreels, animation shorts and so on in a class all on different tapes & DVDs...
    Some players (Sony) can be set to auto resume so you could even queue things to some extent!

  • Toon Boom Quicktimes in FCP... Interlacing Issues

    Hi,
    I've been rendering out Quicktimes out of Toon Boom Studio 4.5 and bringing them into Final Cut Pro for editing.
    I'm getting really bad interlacing issues when playing back on moving objects, particularly on the 1080i plasma I'm using for monitoring. However when paused the image looks sharp.
    The animation is a 1920 x 1080 project in Toon boom, and I'm bringing it into a 1920 x 1080 60i ProRes Sequence. I've tried exporting from Toon Boom to ProRes HQ and Animation quicktimes (both interlaced and progressive), as well as exporting image sequences and bringing them into after effects to export to ProRes. All with the same results.
    Interestingly the quicktimes play in a preview-like quality when played in the viewer in FCP. However when I drop them into a ProRes (non-HQ) timeline and render, they look as they should but with bad interlacing issues on moving objects. Dropping the ProRes HQ quicktimes into a ProRes HQ sequence play in a preview-like mode too.
    Anyone had any experience working with animation files from Toon Boom? I've had similar issues with QTs from Anime Studio Pro but they weren't really noticeable once rendered in the timeline.
    Thanks in advance

    Hi X, sorry for the delay.
    If I drop a 30fps ProRes HQ quicktime into a 1030p ProRes HQ sequence, I get the preview-like quality I wrote about earlier.
    However if I change the sequence compressor to regular ProRes and render, it displays sharp as it should but still has the bad interlacing. The plasma I'm monitoring with can't display 108030p though so I'm judging this from an apple cinema display.
    Exporting from this timeline to 108060i ProRes has the same problem.
    Do you think it's possible the characters in the cartoon move too great a distance between frames that it's causing this issue?
    Thanks

  • Photo interlacing issue

    Hello, I recently got my wife a iphone 5c. Seems fine in every respect except when you take photos. They end up with an odd interlacing like a bad scan or something. I tried searching for a similar issue but seems everything I saw was about an interlacing problem was with the entire screen. This happens only with the camera app... the screen is fine otherwise. Oddly enough it does not do it with video and also when HDR is on, the 'normal exposure' that it saves looks good but the HDR has the horrible interlacing. If HDR is off the interlacing is there though. Is there a way to fix this so that we just get nice clear photos?

    I would recommend restoring the iOS and setting it up as new, at least to test. Use iTunes to restore your iOS device to factory settings
    If that doesn't fix it, get it serviced. https://www.apple.com/support/iphone/repair/

  • IMovie '11/Canon M41 30p Interlacing issue

    I just bought a Canon M41 HD camcorder that has a 30p option but has an asterisk and says recorded as 1080/60i (there is no option to record at 720 at all on this model).  I imported into iMovie '11 as full resolution and when I use the Share menu to choose 720p it's interlaced/jaggy.  How can I do 720p at a good quality without the interlacing?

    I haven't been able to solve this issue yet.  Can anyone help?

  • Interlacing issue with AME/Premiere CS5?

    Hi,
    I am having some issues with a file that I am trying to conform using AME CS5 from XDCAM-HD mxf wrapped to wmv output that I need to be able to playout of a black magic card to SDI.
    The source file is 25fps PAL
    If I import the mxf directly into AME (without going via Premiere), I can successfully output an interlaced file at 6Mbit CBR using the main profile and it plays out correctly on the monitor I am using to check playback.
    However, I need to remove 2 channels of audio from the hires and overlay a logo. I have done this by importing the file into Premiere, making the necessary changes and exporting it to AME.
    When I do this, if I chose interlaced as my output from AME the resultant file is terrible and movement is extremely jerky. If I change the output to deinterlaced I see an improvement but it is still not as good as the file that has been imported directly to AME without going via Premiere.
    I need to understand (and resolve) what is happening within Premiere that is making a difference to the output file from AME.
    Changing the output format to something other than wmv is not really an option at present.
    I have tried changing the Interpret Footage settings in AME along with various other options. I appreciate that I may not have supplied enough information here for someone to be able to assist but if you let me know what else you need to know I will happily provide it.
    Thanks

    thanks for the clarification and apologies for the misunderstanding. I don't work in the video editing side of the industry so I'm not familiar with a lot of the lingo.
    Unfortunately I have an absolute requirement to either use the prproj (or ideally the FCP xml option) output so that I can substitue the source media in the project and send multiple jobs to AME using an automated process.
    I'm trying to understand what Premiere is doing to the hires file when it exports it that is causing the difference in the resulting output from AME when compared to submitting the hires directly to AME.
    I'm just in the process of setting up a new project that only contains the hires, with no logo added, no settings changed and I am going to run that through AME using the same epr that I used on the direct import of the hires.

  • Interlacing Issues after Exporting - Help!

    Hello -
    So I'm having some very frustrating issues exporting a project from Premiere CS3. I'm trying to output to a lightweight quicktime format - either mp4 or an h264 .mov file. I've shot footage using a canon legria hf s10 camcorder, importing at 1920 x 1080 at 25 fps. I used apple's new iMovie to import the clips to my computer (because premiere doesn't seem to natively support AVCHD, which I think the camera shoots in). So I capture the footage with iMovie, then import those .mov files using premiere.
    All this is fine, until there's a lot of horizontal motion in shots, where I get these ugly interlaced lines that really mar the quality of my footage. I'm trying to produce some videos in a professional setting, and these lines really hurt the overall perceived quality of my work. However, I thought I had found a fix when I selected the problematic clips and right-clicked, selected "field options," and clicked "always deinterlace." After doing so, the ugly lines disappeared, and when I play the clips back in premiere, I have no issues whatsoever. However, when I EXPORT the clips, the ugly interlacing somehow RETURNS... which is exceedingly frustrating, because I can't figure out how to get rid of them.
    When I export, as said before, I am trying to create a relatively low-quality, 854 x 480, square pixel quicktime file of some sort. I've tried any number of exporting options to no avail.
    Therefore, I am at your mercy. Endless gratitude to anyone who can help solve this plight. Here's a still example of the problem for your consideration:

  • Interlace issues from 1080i50 to - iDVD, PS3, Apple TV and even FCE canvas

    Hello all,
    I am struggling to get smooth output from my FCE, interlace is thwarting me at every turn. I can produce a smooth DVD but at low quality with a work around as described at end of post, but really want smooth HD file, here is my workflow an plight
    Have captured footage with Panasonic HDC-SD5 AVCHD camcorder in 1920 x 1080i50, imported into FCE with the newer 1920x1080 apple intermediate codec at 25fps
    On inspection in the canvas set to 100% I see interlace jaggies, play back is not smooth either. So this is the first question should I really interlace in the canvas at this point?
    Export to iDVD, use Quicktime Movie export, import into iDVD and produce DVD - result awful not smooth and blurred.
    So try to export a HD MP4 , using Quicktime conversion. I produced in 1080i at 25fps and it's jumpy and blurred on the PS3 in playback. Then I did one at 29.97fps and as expected the video jumped every second BUT there were periods of smooth HD playback so I was so close! But just could not find the correct export setting.
    Export to Apple TV directly from FCE produce awful results, however if I use the Quicktime movie and run it through visual hub I can encode for Apple TV using H.264 it de-interlaces correctly but movei not smooth (so it just removes a frame)
    So, over a period of 2 days I have tried seemingly every export in Quicktime conversion for PS3 and Apple TV, VisualHub conversions and MPEG StreamClip all producing blurred or jumpy results due to interlacing.
    The only smooth output was achived by using technique of another poster
    Export Quicktime Movie and use Mpeg_StreamClip exportthat movie in
    DVPRO50, set to PAL and 16:9, no deinterlace
    then take movie and drop into iDVD and resulting DVD is Smooth
    BUT quality is poor.
    So, the main question is
    How do I get all my nice HD footage out of FCE and onto Apple TV, PS3 or even iDVD in quality and without interlace making it jumpy or jaggy.
    Any help would be greatly appreciated.
    Cheers
    Andy.

    Wow thanks for quick reply. Apologies I didn't give full info.
    I am viewing DVD on TV - well a plasma being played via DVD on PS3.
    BUT, DVPRO50 is the only output that shows a "smooth" movie, if I playback on the canvas at 50% the interlace line are gone due to the scaling BUT the movie plays jumpy, so the DVPRo50 method is the only way I can get a smooth pan for example, every other method just gives a jumpy playback on DVD.
    iDVD is set to Production quality, when I do a QT movie direct to iDVD without the DVPRO50, the quality is better but the movie is jumpy.
    The movie is also 47 minutes long - it's quite big, file produced is about 19GB.
    Also I understand about getting HD quality and BlueRay disk etc, but I would expect to get DVD quality from iDVD, doing the DVPRO50 conversion makes it pretty bad. but smooth!
    As I said the anooying things is when I exported to MP4 on quicktime at 1080 HD and 18000kbps and 29.97 it also plays smooth for a short bursts of a few seconds (albeit jumping every second to 25 -> 29.97 issues), in 25 fps it's just blurry and jumpy. (playback on PS3)
    Thanks
