Help with "imgWriteParam.setCompressionQuality(quality)"

I read the documentation related the above method...yet, i was not clear how it works, though i have implemented it in my program. Which algorithm(like LZW, Run Length, Huffman) does this method really use and how? Urgent help needed...

First, how about specifying the real classname?
Second, how many threads are you going to create for this?
Third, did you ever consider looking at the source?

  • Help with getting high quality DVDs from AVCHD footage

    Hello,
    I know enough about video editing with PE7 to be dangerous, and was hoping someone could help me out.
    My question is regarding getting the highest quality standard DVD from AVCHD footage. I have a Sony HDR-SR12 camcorder recording in AVCHD. I am editing footage natively in AVCHD with PE7 on a quad core system. No problem with that. However, when I export to standard DVD the quality of the video goes down drastically. (Yes, I know burning to Blu-ray would give me higher quality, but I am giving this DVD to a friend who doesn't have Blu-ray).
    So far I have tried starting my project in both HD 1080i 30 5.1 channel:
    General
    Editing mode: HDV 1080i
    Timebase: 29.97 fps
    Video Settings
    Frame size: 1440h 1080v (1.333)
    Frame rate: 29.97 frames/second
    Pixel Aspect Ratio: HD Anamorphic 1080 (1.333)
    and Full HD 1080i 30 5.1 channel:
    General
    Editing mode: HD 1080i
    Timebase: 29.97 fps
    Video Settings
    Frame size: 1920h 1080v (1.000)
    Frame rate: 29.97 frames/second
    Pixel Aspect Ratio: Square Pixels (1.0)
    But I see no discernable difference in the quality of my output onto DVD.
    This is where my knowledge is lacking...how can I get the best quality output from my AVCHD onto a standard DVD? Is there some format I can convert to first, and then burn to DVD? Also, I am willing to break the footage into a couple of DVDs to improve the quality, but I don't know how or what to do for that.
    My footage looks REALLY great when viewing from the HDR-SR12 direct to HD TV with HDMI cable, but not very good on the DVD. My footage is of a ballet recital, and I lose definition in the faces, costumes, etc on the DVD output.
    Any help is appreciated! Thanks!

    Hey Gina,
    This may be a year late, but as I have been pulling my hair out trying to solve this problem for the last 48 hours I finally did find somewhat of a work around, but it requires Adobe PP CS4.2.
    There is a plug-in here:
    http://www.mainconcept.com/site/prosumer-products-4/mpeg-pro-hd-7850/features-7861.html
    Which will actually output your edit as an AVCHD file. You can then burn this straight to an AVCHD using Nero 9 and keep the highquality level of your clips and not need Blu-Ray. The DVD player will need to be AVCHD capable, but I just bought one of those for $40 as compared to the $200+ of most Blu-Ray players.
    Hope that helps.

  • Help with choosing Export quality CS4 souce sony handcam hybrid

    I am having trouble getting a good quality once I export my sequence . I have tried different formats and none of them seem to be as good as the original source video.  I am using a sonyhandycam hybrid with the quality set at 9m HQ.  What would be a good project setting and a good formant and options to export for the best quality? I would like the best quality I can get for a DVD, I sometimes do some uploading to youtube so any tips on that would be good as well.  But my main focus is best quality for a DVD.
    Thank You!

    Thank you for your advise but how can I get very good quality on DVD then.
    as long as your project is <60min, iDVD will create best quality technically possible (=using the highest bit-rate, 9MBit/s) standards allow .
    it is not a prob of the tool, but the standards. your source is 1920x1080, a DVD can contain only 720x480 ..
    if you want 'higher' delivery-quality, consider BluRay (hmmm?) or a MediaPlayer (AppleTV, WD TV, PS3, .. )

  • NEED HELP WITH RESOLUTION AND QUALITY?

    hi guys
    i have been making these vector type portraits in photoshop for the last couple weeks, it has all been going well until, when some one puts it up as a display picture on facebook etc the quality is not as good as when i just view the picture on my computer.
    i have been starting the new in photoshop and using 800x800 pixels and the res at 72 pixels/inch, am i going wrong here some where? or is it the fact that i am using photoshop to do this task? im sure there are a lot of people that will advise me to use illustrator, which i have been thinking about doing. but i would like to know if this can be solved in photoshop first.
    thanks in advance for your help
    it is slightly pixel-ish in areas...
    P.S. i have also notice it is work in the text "faulty" area.

    so let me try get this straight lol the picture on the left is on facebook and that the quality is rubbish because its on facebook? 
    because when i opened the one on the right just to look at it, the quality was the same as when it was in photoshop.
    they are both obviously jpg, so it has to be the fact that it is showing from facebook that makes it grainy, right?

  • Zen Vision M - help with mp3 sound quality - decreases after trans

    I use the Media Explorer to transfer songs from cd to the player. After?recently upgrading my OS to the XP service pack 2 (even though I don't know if this has anything to do with it), the sound quality of the mp3's has decreased when playing back on the player. Sound is real tinny. I checked the settings and?it's set to the highest quality. I always keep it at that and never change it. What am I missing here?

    Check the transfer settings on WMP, it will often override and convert content when you transfer it even when you don't want it to.
    Plug in your ZVm and wait for it to be recognized by your computer.Run Windows Media Player(in WMP)Tools->OptionsClick on "devices" tab (You should see your ZVM displayed in list)Click your ZVM in the list, and select propertiesClick the Quality TabChaing the settings from "Automatic" quality detection to manual and set alll the settings to the highest quality. Then give your transfers a try again.

  • Help with photo import quality in iMovie!

    The resolution of the iPhoto (5.0.2) pics once dragged into iMovie (5.0.4) severly deteriorates on my iMovie project. The photos are 21 inches widecrystal clear JPEGS in iPhoto, Preview and Photoshop, except once dragged onto iMovie they look blurry and pixely. My digital camera is a Sony 7.2 (shot pixs at 5M)
    Playing project footage on full screen in iMovie looks this way as well. So it is not just the import still shot on the clipboard that looks bad.
    How do I fix this problem to get clear quality ?

    Create your iMovie project in a high quality format (choose the highest one possible) and then the pics you import will be imported in a high quality. iMovie automatically adjusts the quality of your pics and movies based on the quality of the iMovie project you are creating.
    I'm not sure what you mean by "a high quality format", hlokty. Are you referring to the iMovie Playback preference, which lets you pick one of three playback settings?
    If so, note that preference does NOT affect the quality of the imported image. It has no affect on the quality of project clips like video, photos, or anything else. The preference only affects playback in iMovie itself. Low quality improves the playback smoothness. High quality improves the playback image.
    If should be noted that iMovie NEVER shows us all the quality that's there, for either video or photos. That must be kept in mind when viewing photos imported to iMovie. It's important to not judge quality by what you see in iMovie. iMovie is a video editor, not a video player.
    There are many Topics here discussing photo quality. To find them, search for words like "blurry" and "jaggies".

  • Help with display quality (LCD TV)

    I've hooked up my Mac mini to my Samsung 32" LCD TV via HDMI cable.
    The overall quality is just far from desireable and is taking away all of the fun from using this new mac.
    I set the resolution output to 720p, which is what the TV supports. So that's good.
    I played slightly with the Contrast and Brightness on the TV settings.
    But I must be missing something. Although the image is sharp, it's very difficult to read from 6ft away, pictures look terrible (seeing the same picture on a different computer and monitor is so much more revealing), and the display is bad for everything basically.
    Please help with any settings suggestions or perhaps a detailed guideline for my setup.
    I started to configure a color profile on the display settings but the results weren't that great and I reverted to default. Too many subtle changes. My colorblindness probably doesn't help.
    Thanks.

    Thanks for the response.
    It's the latest Mac Mini with 2.5ghz i5, AMD Radeon HD 6630M, and 8GB RAM.
    I am familiar with the "Just Scan" setting under picture size on the Samsung TV.
    I'll look for the digital noise reduction.
    Are there complete guides with recommended settings for different setups? Or maybe even general, that would help me here?
    Thanks.

  • FCP Novice needs help with video quality and FCP 5!!

    Hi,
    I have a real problme that I cannot seem to fix. I think its because I am doing something really wrong!
    I have a Sony HC42E MiniDV Camcorder which by default records video in full widescreen. I recorded several tapes this way and have now begun trying to edit them in FCP 5.04 (Tiger 10.4.6). Whenever I log and capture my clips they appear to be fuzzzy and unclear on the Mac monitor whilst being totally crisp and sharp on the camcorder viewfinder. I tried capturing using the DV PAL 48Khz Anamorphic Preset which keeps everything the right size (the final output needs to be true widescreen and not with black bars added) but the resulting video on screen is blurry and bitty. I then tried capturing using the DV PAL 720 x 576 normal preset and the video is a little clearer on the screen (for both presets I have chosen lower field dominance) but when I play back it plays back in widescreen on the mac canvas window but at 4:3 on the camera's viewfinder.
    I then assumed that maybe this is just becuase the mac screen (CRT by the way) doesn't use fields. So I exported the sequence as a QT movie using DV PAL 16:9 and used quicktime (OS9 Classic - my compressor has never worked because of the dreaded "unable to connect to baackground process" problem which I've never managed to correct) to convert it to MPEG2. When I import this as an asset into DVD Studio pro 4 and set the track size to 16:9 it comes through at the right aspect ratio. However it looks blurry on screen. Thinking that this will be fine on a TV I burned the disc - inserted it into my DVD player (a good one!) and watched it on my new 32" widescreen TV (a good one!) and the picture qualitty is poor. Its so much blurrier and bittier than the original footage looks when played through the camcorder's viewfinder!
    The final footaage looks like an old VHS recording that's a year or two old!
    Does anyone know how I can capture my footage in FCP with the maximum quality, edit it without quality loss and the export it for DVD again without such significant quality loss whilst all the time keeping it at proper 16:9 widescreen?
    Is there some presets I should be working to?
    I'm tearing my hair out! Help!

    Hi Guys,
    thanx for your replies.
    here's the latest:
    Brian, I followed your instructions and the DVD burned successfully. However the video quality of the dvd when viewed on my TV ('ve tried on all 3 of my tvs now) is still a lot poorer than the quicktime movie that was imported into DVDSP4. When I play the original QT Movie on my Mac CRT monitor it looks a little blurry and grainy because I guess its non interlaced however when viewed on an external Video monitor it looks great - very sharp.
    When I view the burned DVD on my television the picture quality looks like the non interlaced version of the original QT Movie that appeared on my Mac CRT and not the sharp interlaced (lower field) version that appeared on my external video monitor.
    Its almost like taking a sharp jpeg into Photoshop and applying a gaussian blur of about 0.3 followed by jepg compression compressing it down to 5% quality!
    I'm totally mystified. Can the conversion to Mpeg2 be removing all interlacing so that you get the less sharp computer monitor look? I just want the video on my final DVDs to be as good as the original source footage! I appreciate that along the way there might be loss of some quality but surely not that much?
    Does this make sense to you guys or am I still doing something very wrong?
    Robert: I have tried setting all manner of drives including a fresh external firewire HD with nothing on it (clean out of the box) but it doesn't seem to help.
    Brian: I tried the no network suggestion a few months back but I'm not sure if I got it right. At the moment I have broadband through an external speedtouch usb modem and am also connected (occasionally although not for the last 3 months) via a crossover cable to my PCs ethernet card. When I last tried the No Network solution I had immense trouble getting my internet to work again! Can you please help me by directing me to the best ay to do this while protecting my internet settings?
    any more help guys would be greatfully appreciated.

  • Help with quality of exported files

    The problem: I'm trying to get a good quality, 34 minute movie onto a DVD with chapter markers separating individual short films. This is supposed to be a compilation of 8 family movies, in addition to an introduction and credits at the end. Four movies are old movies made in iMovie and are .m4v files. Four were made in FCE earlier this year. I linked everything together in a Master Sequence, putting pauses in between each with some livetype text files to introduce each video. The m4v files were imported and placed in the master sequence. The others are nested sequences. I put chapter markers at the beginning of each section. My intention was to export this one master sequence as a quick time movie, then put it into iDVD.
    It worked, but the quality was horrible! Everything became grainy, even the movies I had previously created in FCE. This was very disappointing. So I expertimented with a few things, and here’s what I found.
    When I exported a quicktime movie, the quality degraded. It became grainy. Also, it changed the aspect ratio and stretches everything horizontally, as if to take a standard size screen and stretch it to a widescreen. It did this even with the original movies I had made in FCE. I don’t like building self contained movies using this mode because the file sizes are too big, so when I export I tend to use quick time conversion. In this case, I was hoping a non-self contained movie would merely point to all the original content and not add compression artifacts (or something like that). It turns out it made it worse.
    When I tried to export a quicktime conversion, 640x480 VGA, best quality, H.264, the machine couldn’t do it. It ran for an hour or so and then crashed. Twice. That is for the entire movie. When I export individual clips (3-6 minutes) it works. The quality is good for movies made in FCE, not as good for imported m4v movies made long ago in iMovie, but better than what I get exporting quicktime movie files, either self contained or not. This is surprising to me, because I was expecting the export quick time movie command to produce the best quality. Also, I’m concerned that if I was able to create this, iDVD would not see any chapter markers anyway.
    So there is a problem either way. Experimenting has led me to discover several questions/issues which need answering:
    Issue #1: Why can’t I get a quick time movie of the same quality as what I see on the canvas, using the quick time movie export command? On a side note, the user's manual says something about a settings pop up menu where you can deselect the "recompress all frames" option. I can't seem to find this, and was thinking maybe that would help.
    Issue#2: Why do m4v files which are very high quality in iTunes suddenly become poor quality when imported into a sequence? Seems to be an import problem, because the movies are already grainy when they’re on the canvas. I thought about making XML files and importing them that way, but the original project files in iMovie are gone.
    Issue #3: Why do I end up with a stretched picture if I export quick time movies and there are mixed aspect ratio contents in the sequence (the m4v files are widescreen, the others are not)? More important, how to I get FCE to not do this?
    Issue #4: When I export movies using quick time movie (not conversion), the grainy movies actually look better when played in VLC. They also look good when opened with FCE. How can I get that kind of quality in quick time, or at least in iDVD? Perhaps that would solve my problem.
    Thanks for any help you can provide.
    E

    Thanks for the response. I’m not fluent with codecs or video compression, so this project quickly became more trouble than I expected.
    It turns out the nested sequences are not H.264, the compression field is blank for the nested sequences. I double checked and the other properties are correct. Sorry about that. The other movies, though, (ones built in iMovie for iTunes) are H.264.
    These four . m4v movies are in 960x540 and 480 x 272 because of the way they were exported in iMovie (Share -> Export Movie opens a menu with four sizes: Tiny 176 x 144, Mobile 480 x 272, Medium 640 x 360, and Large 960 x 540).
    I just imported the final products (what was exported from iMovie) as clips into FCE. Sounds like I should not be doing that. The original media is on my computer, but not the iMovie project files, and for what I’m trying to do it’s just not worth the time to rebuild the movies in FCE.
    Bottom Line: Here’s the current status of the project:
    All eight of the movies, by themselves, play well in quicktime. I can put all of them on a DVD, and they still play ok. I wanted to string them all together in one sequence, with some transitions in between (creating a “Play All” option on the DVD). That’s why I nested the sequences, and imported the movies made from iMovie, than added chapter markers. Unfortunately, putting these different types of media together and asking the computer to make one sequence is creating a mess. So I’m sticking with Plan B and putting the movies on a DVD without trying to merge them into a single track.
    A few follow up questions…
    Out of curiosity, when you say “convert everything to QuickTime DV NTSC 720x480 at 29.97fps with 48k audio,” do you mean the original media (all of the bits of video and stills that came from the camera) or the edited sequences I’m currently working with? As a lesson learned, should I be changing properties of clips before importing them to FCE, so the source material has consistent aspect ratios?
    The still images, though they are huge, show up with much better quality than the movies (which is expected, and I’m ok with). So I get a product which includes both video and still images, where the images are very sharp and the movie portions are a bit grainy (because they were taken on a small digital camera). If I change the size on the stills, won’t that just bring the still image quality down?
    I’m still baffled at why using the export quick time movie command makes a video of lower quality than when using quick time conversion (in other cases as well, not just this project). In every case, I’ve got digital pictures and movies from my digital camera, and some text in FCE or LiveType files on top of that, usually with additional audio tracks.

  • Help with reducing the size of an image but keeping the quality

    Hello,
    I am wondering how do I resize an image but keep the quality. I am creating a folder design for work and I want to include 6 images on the back each of 156px x 118px.
    The images I have are slightly different in size but for example sake one of the images that I have is 225px x 158px. The quality is very poor when I reduce the size.
    I have tried changing the ppi to 72 and to 300, I have also tried resizing all in one go and in a number of goes and I have tried the bicubic sharpener but I have just had no luck with it.
    I am wondering if anyone can help with this,
    Thanks
    Tracy

    Hi Tracy,
    A couple of questions:
    I am creating a folder design for work...
    So this is printed? How large? Pixels are not a unit-of-measure for print.
    If for print, you are looking at ppi of 300 or higher AT PRINT SIZE.
    So, say you want a 3in x 4in picture. That would mean your original would have to be at least 900px X 1200px. (ie 300ppi x width, 300 ppi x height)
    If your original files are not at least that resolution.. . it is hard to add quality after the fact. Unless your are working with vector art.
    I have tried changing the ppi to 72 and to 300, I have also tried resizing all in one go
    Be sure to do that on copies of original. Keep in mind the PPI number by itself is completely meaningless. It only has use in describing a to be printed image when combined with the print size.

  • Help with photo quality

    I hope help is available but know fixing this is a long shot. Ten yrs ago I made a video using photos only. I do not remember what program I used to create it-probably something pc based. I have a copy of this video in Itunes captured as MPEG-2.
    I dragged it into a FCP7 project I am creating and it plays without audio and the photo quality is not good.
    To fix the clip, I tried 2 methods:
    1. I compressed it using best 'DVD quality for 90 minutes 'This restored the audio however the photo quality is still poor.
    2. I tried using the program MPEG streaming.It did not improve the photo quality.
    I know the indiv. photo quallity is pretty good becauseI have these photos in IPhoto.
    Does anyone have any other ideas?
    Thanks, Sandra

    Thanks Mtd..is it Meg?.
    I was pretty sure that was the case, but actually wanted to use some of it because it is for the same client and thought it would be fun to use that file. As I think of it, you gave me an idea. Maybe I will start with the poor quality file which the client knows well and morph it into a clear (new file) with those photos....Could be fun
    Thanks again

  • Help with getting a better understanding on how APEX submits its pages

    Hi,
    I have implemented jquery with my app and have just applied the jquery UI plugins.
    I have the jquery UI dialog function working which gives the users some options. Now as an example, I have a cancel and a continue button. If the user clicks cancel it simply stops the page from submitting. Which works perfectly however, I cannot get the continue button to carry on with the request.
    I gather that I will need to determine what the href was of the link/button that was clicked before the dialog box appears.
    I know Apex uses a javascript function call doSumit() which simply submits the page but what does it use for other href like links to other pages?

    The problem is that you're taking a camcorder format that Premiere Elements is able to work with and converting it to a format that it can NOT work with.
    That Canon camcorder produces AVCHD video. You should shoot any video you want to edit in Premiere Elements only in MXP or FXP mode. Then, when you're ready to edit the video in Premiere Elements, you should set up a project for AVCHD 1920x1080 stereo. (Unless you're shooting in 5.1 audio. This cam shoots in a number of formats.)
    DO NOT CONVERT YOUR VIDEO BEFORE YOU PUT IT IN PREMIERE ELEMENTS.
    You can then use these specs to output high-quality video for YouTube.

    I need your help with a decision to use iPhoto.  I have been a PC user since the mid 1980’s and more recently have used ACDSee to manage my photo images and Photoshop to edit them.  I have used ProShow Gold to create slideshows.  I am comfortable with my own folder and file naming conventions. I currently have over 23,000 images of which around 60% are scans going back 75 years.  Since I keep a copy of the originals, the storage requirements for over 46,000 images is huge.  180GB plus.
    I now have a Macbook Pro and will add an iMac when the new models arrive.  For my photos, I want to stay with Photoshop which also gives me the Bridge.  The only obvious reason to use iPhoto is to take advantage of Faces and the link to iMovie to make slideshows.  What am I missing and is using iPhoto worth the effort?
    If I choose to use iPhoto, I am not certain whether I need to load the originals and the edited versions. I suspect that just the latter is sufficient.  If I set PhotoShop as my external editor, I presume that iPhoto will keep track of all changes moving forward.  However, over 23,000 images in iPhoto makes me twitchy and they are appear hidden within iPhoto.  In the past, I have experienced syncing problems with, and database errors in, large databases.  If I break up the images into a number of projects, I loose the value of Faces reaching back over time.
    Some guidance and insight would be appreciated.  I have a number of Faces questions which I will save for later. 

    Bridge and Photoshop is a common file-based management system. (Not sure why you'd have used ACDSEE as well as Bridge.) In any event, it's on the way out. You won't be using it in 5 years time.
    Up to this the lack of processing power on your computer left no choice but to organise this way. But file based organisation is as sensible as organising a Shoe Warehouse based on the colour of the boxes. It's also ultimately data-destructive.
    Modern systems are Database driven. Files are managed, Images imported, virtual versions, lossless processing and unlimited editing are the way forward.
    For a Photographer Photoshop is overkill. It's an enormously powerful app, a staple of the Graphic Designers' trade. A Photographer uses maybe 15% to 20% of its capability.
    Apps like iPhoto, Lightroom, Aperture are the way forward - for photographers. There's the 20% of Photoshop that shooters actually use, coupled with management and lossless processing. Pop over to the Aperture or Lightroom forums (on the Adobe site) and one comment shows up over and over again... "Since I started using Aperture/ Lightroom I hardly ever use Photoshop any more..." and if there is a job that these apps can do, then the (much) cheaper Elements will do it.
    The change is not easy though, especially if you have a long-standing and well thought out filing system of your own. The first thing I would strongly advise is that you experiment before making any decisions. So I would create a Library, import 300 or 400 shots and play. You might as well do this in iPhoto to begin with - though if you’re a serious hobbyist or a Pro then you'll find yourself looking further afield pretty soon. iPhoto is good for the family snapper, taking shots at birthdays and sharing them with friends and family.
    Next: If you're going to successfully use these apps you need to make a leap: Your files are not your Photos.
    The illustration I use is as follows: In my iTunes Library I have a file called 'Let_it_Be_The_Beatles.mp3'. So what is that, exactly? It's not the song. The Beatles never wrote an mp3. They wrote a tune and lyrics. They recorded it and a copy of that recording is stored in the mp3 file. So the file is just a container for the recording. That container is designed in a specific way attuned to the characteristics and requirements of the data. Hence, mp3.
    Similarly, that Jpeg is not your photo, it's a container designed to hold that kind of data. iPhoto is all about the data and not about the container. So, regardless of where you choose to store the file, iPhoto will manage the photo, edit the photo, add metadata to the Photo but never touch the file. If you choose to export - unless you specifically choose to export the original - iPhoto will export the Photo into a new container - a new file containing the photo.
    When you process an image in iPhoto the file is never touched, instead your decisions are recorded in the database. When you view the image then the Master is presented with these decisions applied to it. That's why it's lossless. You can also have multiple versions and waste no disk space because they are all just listings in the database.
    These apps replace the Finder (File Browser) for managing your Photos. They become the Go-To app for anything to do with your photos. They replace Bridge too as they become a front-end for Photoshop.
    So, want to use a photo for something - Export it. Choose the format, size and quality you want and there it is. If you're emailing, uploading to websites then these apps have a "good enough for most things" version called the Preview - this will be missing some metadata.
    So it's a big change from a file-based to Photo-based management, from editing files to processing Photos and it's worth thinking it through before you decide.
