Motion Graphics quality loss when encoding to DVD

I have completed a logo reveal and movie titles for our short film that we will be authored to DVD. I used AE CS4 and created the compositions as 1050x756 PAL square pixels.
The uncompressed AVI renders look amazing. However, when i encode using MPEG2-DVD straight from AE there is a big hit on quality. I understand that encoding is about compressing and that we need to expect a certain amount of quality loss. But the text is especially bad.
I read somewhere that saturated reds are not particularly well handled by the MPEG-2 encoders. So we changed the color to a more subdued burned orange. We also remove the titles horizontal scroll on the screen that was causing excessive flickering. But there is still a high rate of quality loss on the text.
Is there any special workflow that i should be using, tips or tricks that you know of? I see some awesome intro titles on DVD and the text does not behave in this way.
Any pointers and suggestion you can give, would be greatly appreciated

Robert:
The MPEG-2 encoder in AE/AME is a very good, general purpose encoder.
Commercial DVD titles frequently use high-end, specialized encoders. This includes very expensive, hardware-based encoders.
That said, you could get better quality from the MPEG-2 encoder in Adobe applications by using 2 pass encoding. Unfortunately, the Render Queue in AE only can do 1 pass encoding. In order to use 2 pass encoding, you'd have to launch Adobe Media Encoder in standalone mode, pick an MPEG-2 DVD preset and enable 2 pass encoding.
Specialized encoders include, for example, Cinemacraft SP. It can do multipass encoding and offers a great deal of control over encoding settings. Even as a software-based solution, it's not cheap.
It's also worth pointing out that type for highly compressed media has its' set of do's and don't's. Applying a very subtle vertical blur (Reduce Interlace Flicker) usually helps. Fonts designed for high-resolution media (most families with serifs) need to be used at large sizes, or use sans serif typefaces for smaller sizes, etc.

  • 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!

    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

  • Quality loss when playing DVD authored in Encore on a HD flat screen

    Hi,
    I authored a DVD in Encore and i noticed that when i played it on my pc it looked fine but when played using a DVD player on a HD flat screen and projector there is a significant quality loss- the image became pixelated and glittery. I tried playing 3 other professional videos and they were all fine. Something must be wrong in the way i am authoring my video. The encore file is set to 720x576 at 25fps. I created a .psd menu page to match these dimension and besides the movies, both the menu page i created and the menu templates that are already there in the library when you buy the software, look glittery when played with a projector or HD flat screen and projector. Any suggestions?
    Thanks,
    Eric

    Lack of control over users players/TVs is a problem. And you can try to provide some instruction.
    You are right to test your product to see if you have a reasonable chance of your DVDs looking good.
    First, test them on a DVD player and a standard definition TV. Your test on the PC is not sufficient. If they do not look good here, you have  problems somewhere in your workflow. (I suspect this is the case. In my tests below, I see no flashing or issues like what you describe.)
    If okay there, you need an upscaling DVD player to test on your HD TV. You should also explore the options on that TV for setting size.
    For example, I just put a DVD in my Bluray player (hooked via HDMI to an HD 1080p TV). I can set the player and the TV separately to various resolution settings. Forcing the player to 480 and the TV to Normal gives a picture that looks like the original version, using a regular DVD player set to a 4:3 TV. But when I set the Bluray player back to "HDMI auto" (for the resolution), and the TV to normal, I see a pretty respectible picture.
    I did the same sort of test using a regular DVD player via regular AV cable. Discovered I had it set to the wrong TV type! I could not see a lot of difference in the picture, even if I stretched it. (It was distorted, of course, but not pixelated, just not the crisp look of HD.)

  • Quality loss when rendering to FLV or F4V

    I've got an AE project that includes simple motion graphics and screen capture footage.. when I render it as an MOV, it looks great.. but if I render it as an FLV or F4V, the gradients within the movie look all pixilated. I've tried rendering the project to FLV/F4V from AE as well as rendering a high quality MOV and bringing it into Adobe Media Encoder to create the flash video file. No matter what settings I use, the animation ends up being jerky instead of smooth, and the gradients look terrible. Any thoughts would be much appreciated.

    Look at the two images, the one on the right is my MOV .. the one on the left is my FLV. Below those are the settings I used to render the FLV.

  • Quality Loss When Importing Video into Timeline...Any Ideas??

    Hey all -
    I'm fairly new to CS4, so excuse me if this question is a little dumb.
    I've offered to edit a friend's actor showreel to familiarize myself with CS4. He gave me a bunch of HD clips: they're .MOV files, and are 1920x1080 and 23.976fps.
    I can import a clip and drag it into the preview screen in the middle: it looks fine. However, when I drag it onto the timeline, it suddenly looks faded and blurred. It's not horrible, but it loses the vibrancy of color, the sharpness and the contrast of the original clip. A lot of the quality is gone.
    I've tried opening the project with a number of different settings, no difference. I thought it might look OK when I exported it, but it looks just like it does on the timeline monitor: a little washed-out, blurred, just not as nice as the original.....
    I'd hate to present it to my pal looking like this, can anyone suggest a solution? I tried everything I could think of already....
    Thanks!!
    B

    Hi Hunt -
    many thanks for your reply. I've spent the last couple of days trying to follow your advice and do more research.....still no luck.
    Firstly, I upgraded my OS to Windows 7, thought it might help for some reason. Didn't. I downloaded a bunch of codec packs.
    Gspot reports:
    Codec: AVC1
    Name: H.264
    Codec Status: undetermined
    So I'm basically running through all the possible output formats, but really it doesn't seem to be an encoding problem: the quality loss happens as soon as I move the file from the preview screen to the timeline.
    If you have any othe suggestions I'be very pleased!!
    Thanks

  • Bad quality playback when burnt to DVD

    Hey,
    I have burnt my imovie project using the share - media browser in imovie and then the professional setting in idvd. When I play it on my new sony dvd/bluray player on my full hd tv with HDMI lead it has very poor playback. The sound is very muffled and the picture is slighty jumpy.
    However when I played the dvd in my parents old dvd player still running off a scart lead but again an hd tv it was perfectly fine with great sound. Can anyone explain why this is and how I might achive a good picture and sound quality in my dvd/bluray player?
    Thanks!

    Hi
    I think there is one more thing to this.
    • Your parents DVD-player most probably has a superior picture correcting chip in it
    BUT
    iMovie'08 or 09 or 11 - are not the tool to use when wanting a DVD in as good quality
    as DVD can be (SD-video as old TVs)
    Due to that they discard every second line resulting in a less sharp picture.
    I use
    • iMovie HD6 - or - (But do not use "Share/Export to iDVD" - only directly import into iDVD
    from within iDVD ! )
    • FinalCut (any version) - or -
    • FotoMagico™
    They all delivers maximum to iDVD
    Other thing I do
    • Secure a minimum of 25Gb free space on Start-up (Mac OS) hard disk
    • Use good DVDs - I use Verbatim
    • DVD-R
    • Burn speed set down to x4 or x1
    • Pro Quality encoding

  • Quality loss when converting pro res to mp4

    Hi
    I have a problem with the workflow from After Effects to a final .mp4 video.
    I have been editing time lapses in After Effects, and exporting them as Pro Res HQ- all good so far. However, I can´t seems to be able to convert the Pro Res file to a .mp4 (or quick time .mov for that matter) without significant quality loss. This happens if I convert using adobe media encoder, or if I import the Pro Res files to Premiere and export through Premiere.
    However, if I import the original JPG/TIFs to Premiere, and export using the exact same setting- I get a better result. Also, when I have uploaded the original Pro Res HQ file to vimeo, they do a much better job of converting it than Media Encoder or Premiere do when I convert to .mp4 (I´m aware that it is not the same conversion, but still..).
    So my conclusion must be that AME and PP does not convert from Pro Res to other codecs very well? I have to work on my files in AE, and I need .mp4 as the final product (requirement for uploading to a stock site). How do I do this without getting lower quality video than if my workflow and export was only in Premiere? After Effects does not render out .mp4 very well it seems...
    A screenshot showing the setting I use when exporting from PP or AME. The settings produce a good result when exporting other files from PP, but not the Pro Res files I have exporter from AE.
    Thanks for your input!

    Figured it out after testing various settings. I read an article describing the keyframe interval setting at 1 as the best option- clearly that was wrong! After searching I found a better description of keyframe interval: "Having too many keyframes severely reduces quality, because the efficiency of reusing image areas from previous frames is completely lost at each keyframe – the encoder has to "start over" at every keyframe. Therefore, we want as few keyframes as possible to achieve the highest quality for the given target bitrate."
    Tested with keyframe settings 25 and 75- both seem fine.
    Thanks for the feedback

  • Major Quality loss when editing in Iphoto 09

    Hi,
    I am a new user to Imac and Iphoto and I saw that when I edit an Image in Iphoto, I loose a lot of my original data.
    I have found that I can return to the original picture, but I wish to edit (especially using the CROP function) then print the Image on 20x30 cm size and therefore I need all the quality I can get.
    When I Crop either JPEG or .RAW formatted images (for example 10 MBytes in size) even if I select the COMPLETE image, I am left with only 4 or 5 Mbytes of data.
    It gets much worse when I really Crop a part of the picture.
    A 12 Mega pixel photo should supply sufficient data to cover a complete wall, but for some reason a lot of quality is lost when I use any of the editing features.
    Am I doing something wrong ?
    Should I change any of the settings ?
    Thanks for your advice

    Welcome to the Apple Discussions.
    the only difference is that Iphoto took my quality !!
    Are you basing the "quality" loss on visual appearance of the photo or on the resulting size of the jpeg file? If it's the latter that is really not an accurate method. True, some information is lost with a jpeg edit and save (only the first edit in iPhoto results in additional jpeg compression) but, in my experience, you would have to print a VERY large print before seeing any noticeable image degradation. I've compressed jpegs as high as 60%, i.e. a quality setting of 40, and for most all uses up to 5x7 prints haven't seen noticeable image degradation. However, I realize image quality is subjective and open to individual interpretation.
    So unless you are visibly seeing image degradation I wouldn't worry about the file size reduction, especially in iPhoto as it's compressed only once no matter how many edits are made and saved. Apple uses a compression algorithm that gives the best image quality for the amount of compression it uses.
    The following is from the Usernet FAQ site article "JPEG image compression FAQ, part 1/2':
    Subject: [4] How well does JPEG compress images?
    Very well indeed, when working with its intended type of image (photographs and suchlike). For full-color images, the uncompressed data is normally 24 bits/pixel. The best known lossless compression methods can compress such data about 2:1 on average. JPEG can typically achieve 10:1 to 20:1 compression without visible loss, bringing the effective storage requirement down to 1 to 2 bits/pixel. 30:1 to 50:1 compression is possible with small to moderate defects, while for very-low-quality purposes such as previews or archive indexes, 100:1 compression is quite feasible. An image compressed 100:1 with JPEG takes up the same space as a full-color one-tenth-scale thumbnail image, yet it retains much more detail than such a thumbnail.

  • Quality loss when exporting to quicktime (no conversion)

    i'm trying to export a fully rendered project in final cut pro (6.0.2).
    i'm using the option i always used:
    "export -> quicktime movie..." (not "using quicktime conversion")
    the idea was to convert the movie later to h.264 (using the quicktime pro player).
    normally this always gave me a quicktime movie with ± the same quality as when played directly in final cut.
    no difference whether exporting as self-contained movie or referenced movie (besides the result file size of course).
    only, now it's different, see here (quicktime player left, final cut right):
    the text (done using LiveType) is displayed in completely unusable quality. (difference in color etc. doesn't bother me right now)
    where does that come from? in final cut i don't see this rendered quality anywhere...
    i also tried:
    deleting the render cache, rendering the project again, no difference
    export -> quicktime movie, "self-contained" or referenced movie, no difference in quality.
    i didn't have this problem with the same project some months ago. back then i probably wasn't running 10.4.11 and quicktime 7.4.1.
    any idea what to try?

    There is no quality lost.
    The default of QuickTime player when showing DV is to display 1 field and double height the image. This is to avoid interlace combing on the non-interlaced computer display.
    IF you type cmd-j and bring up the info for your clip, thusly:
    In the lower right corner you'll notice the High Quality flag:
    Setting it will take you from this:
    to this:
    Alternatively, you can go into the QuickTime Player preferences and set the default there:
    Make sense?

  • 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.

  • Quality Loss when sharing

    I have recently upgraded from Windows Movie Maker to Premiere Elements 8 and I have noticed a considerable loss in quality when I have burned my project.  The source media is pretty poor, I use a Panasonic VDR-D160 mini DVD camcorder (yes it is a total nightmare getting importing the footage), and when I import the footage it is a .VOB file.  The stats for the .VOB files I am working with are 704 x 576 picture that goes at 25 frames per second.  The data rate is 9558kbps and the total bitrate is 9814kbps.
    The first project I have done is very straight forward, with minimal editing and no effects.  However, when I burn it to a DVD or a DVD folder it changes the frame to 720 x 576 and reduces both the data rate and bit rate to 7464kbps and 7656kbps respectively.  This creates an obvious pixilation of the image - especially for parts of the video that are moving and it can be seen on lower resolution televisions.  In sharing/publishing the video, how do I retain the same quality as the original?  I have been through the help, and due to my lack of understanding of premiere elements I have not been able to figure out whether it is just a matter of changing one of the settings.
    Thanks!

    Unfortunately, you are starting with material that has already been compressed heavily to the MPEG-2 format/CODEC. Then you are editing and outputting to a Scaled up (the DVD-spec for PAL) and then re-compressed to MPEG-2. This is a triple whammie. Because PrE does not do "smart Rendering," what you see is what you will get.
    A better choice for limited editing, basically just Trimming the material, would be a program that does "smart Rendering," where all material, that was not altered, except to remove portions of it, would NOT be Transcoded a second time to MPEG-2. I believe that some of the Sony Vegas products do this, but there are others. If you Google "smart rendering," you will see several programs, that feature this. I would choose from those.
    You will still have the Scaling issue, unless you completely allow your smaller than spec. material to be surrounded by black. If you Scale in an editing program, even with smart Rendering, it will then need to be Transcoded to MPEG-2 all over again.
    With that footage, the choices are very limited.
    Good luck, and sorry for the bad news.

  • Quality Loss when saving Jpeg from Camera Raw

    I am try to do some color correction on 400 wedding photos. I open like photos in Camera Raw then synchronize, make a few additional adjustments and then save the photos as psd files. When I save the files, the quality drops dramatically. I can see pixels and jagged edges (looks like steps) on anything curved. The photographer will not give me the RAW files, so I have to work with these high quality jpegs and I would prefer to use camera raw as it is nice and easy to fix many of the photos quickly. How can I save these files so as to not lose quality? Oh, I am on a Mac.
    --K

    Ramón,
    now I am quite baffled. For years ago I conducted respective tests and demonstrated, that repeated saving with the same "quality" does not introduce image deterrioration; others did the same tests and came to the same result.
    Now, to be sure, I did it again, and the result contradicts my earlier findings. Although the deterrioration is after five consecutive savings practically irrecognizabe without hugely amplifying it, it is there, and that is an issue of principle.
    While it is possible, that I and others made some error in those tests, the question is (for me) what causes the difference.
    I verified, that the encoding parameters are unchanged. Thus the difference must come from the calculation required to transform between the original pixel values and the encoded values by
    a. the conversion between RGB and YCbCr,
    b. the discrete cosine transform (a variation of Furier transform).
    However, any differences resulting from the calculation (iteration, rounding) should be eliminated by the subsequent lossy step, the "quantization" (which is an euphemism for "throwing away most of the data"). Even if there is a difference between the first and second savings, there should not be any between the fourth and fifth savings - but there is.
    One explanation could be, that the encoding and decoding functions work with different precision, though this sounds very outlandish.
    Anyway, darn.
    Re the encoding parameters: they *have to be* stored in the JPEG file, otherwise the data could not be decoded, except by that program, which knows the parameters. However, JPEG is not designed for human consumption but for computers (this fact makes testing a program, which reads or writes JPEG data a serious PITA). The metadata can be analyzed only by a hex editor, and one has to know the structure of that data.
    Re knowing, if the file has to be compressed or not: JPEG is *always* encoded. There are different variants of the encoding method, but there is no "unencoded" version.

  • Massive quality loss when converting  a .mov file to an .avi or other

    I have been making short videos using final cut that look great in quicktime format. But when I convert them to any format that can be used in powerpoint or other window applications I am suffering a huge loss of quality. What am I doing wrong or how can I get better quality conversions?
    Thanks

    What settings are you using to export? Lousy looking video is usually a result of not enough bitrate or major resizing/scaling of the video.

  • Quality Loss when transferring AVCHD File from Flash Card to iMovie

    I have a Canon HF100 and the HD video looks great when I play directly from the video camera to the television. However, there is a loss in quality when I import to iMovie 08 and play the HD video on quicktime. How can I prevent the loss in quality so that playback on my iMac equals playback directly from the video camera to the TV?

    First, be sure to import at "Full" 1920x1080.
    Second, when you "Share", pick "Share"/Using Quicktime. This will let you customize settings. In Quicktime Settings, pick AIC with an unlimited data rate. For a smaller file, you can also try h.264 with an very high data rate.
    You might look at this old post for some details:

  • Quality loss when trimming photo-jpeg videos?

    Hi all,
    I want to do some basic editing with Quicktime Pro to videos made with my digital camera. They are photo-jpeg with stereo sound. With "basic editing" I mean trimming and joining clips, no further processing like color correction etc.
    I wonder whether there is any loss of quality during this process... From my understanding photo-jpeg is much like mjpeg, so in theory there would be no need to re-encode the result (I save the stuff with "Save as...", not via export).
    I made some tests, and for me it looks like there is no re-encoding. Does anyone know whether this is true?
    Thanks,
    Thomas

    Only an "Export" would re-compress.
    Save As merely puts your trimmed or joined files into a .mov container. The original codecs are used again.
