  1. I tested to encode something in a HD format, and I tried like every single basic codec I can use, and each result had terrible poor results. It looks and sounds worse than the original file, which is lossless and perfect. All I want to do is basically resize the video to a HD resolution. The results come to gross video artifacts, from color bleeding to bad looking blurring, and visual artifacts from frame to frame. The audio even chips in to make it more obnoxious. I tried using the MP3 codec and it amplifies the audio to the point of distortion. Why is Super (c) giving such terrible results? I tried to make things loseless and yet it's riddled with artifacts. I don't recall having such trouble with this before I updated it, and now it's just a headache and a complete disappointment. Can any other Super (c) users help me out on this? here is a sample http://www.youtube.com/watch?v=uLDE6Bjwa18

    Super is just a bunch of freeware programs thrown together under a common GUI. You might try something different. Resizing, if done incorrectly, will give you poor results. Re-encoding incorrectly will also give you poor results. You will never get lossless unless you use a lossless codec and don't mind huge file sizes. Any type of conversion will result in some quality loss.

    What's the source videos format? What program did you use to capture it? You can post the information from MediaInfo, tree view, here which will tell us a lot about your source video.

  3. I used camstudio to record the video, which is a lossless codec, so it was pixel perfect. I tried to convert the file to another lossless format, and I tried a whole bunch of other formats as well, but it all ended up riddled with artifacts. All the conversion processing turns out to be terrible. Before, it even had the wrong colors until I enabled DirectShow or something.

    The devil is in the details.
    You likely did something wrong -- we'd need to know all the settings of source and software.

  5. I tried like 20 different settings and codecs so I don't get what I'd be doing wrong. Like I said, I used CamStudio saved as a Microsoft Video 1 AVI. CamStudio apparently has it's own codec, which is lossless, and also included in Super C's codec options. For the output file, I tried FFMPEG and the MEncoder, I tried converting it to an AVI with MPEG 1 through 4 as the video codec, I tried it with DivX, I tried it with CamStudio lossless codec. It all turns out the exact same. The video deteriorates and has a bunch of artifacts. All the video codecs look exactly the same except for DivX or something . I tried to stretch it to 720p resolution and it looks ugly. I tried no change, it still deteriorates. I tried using the highest video bitrate on lossy codecs. It's all the same result. I tried outputting as a MPEG and MP4 files

    Without more details, I don't know what you're doing wrong either.
    As it stands, all you're doing is ranting.

    No way to help more.

  7. Alright, I'll do some more tests and post about it later on tomorrow.

    It sure sounds like you are paid to bash Super.

    That usually doesn't work out too well. Ok, give us:

    Source:
    -Resolution
    -Bitrate
    -Codec (MS video mpeg 1?)

    Desired Output. What are you trying to achieve here? Burn to DVD? To BluRay? Stream on the web?
    Have a good one,

  10. My test file is
    256x224
    12496kbps
    200 fps
    codec is camsoft using MicroSoft Video 1, highest quality settings

    So basically the original video is lossless, and is a desktop recording of a game I'm working on.


    I tried outputting some AVI files

    first one was in a lossless codec named
    Lagarith
    mp2 audio
    DirectShow decode is enabled

    Resolution is the same
    FPS is 60
    Bitrate says 24008kbps

    Result: Amplified audio again for no reason, artifacts like videos I saw yesterday. Bleeding colors, weird artifacts and shapes from moving objects.

    The file size is twice as big too

    Next I use MS-mpeg4-v1 which is the same codec as my input file.

    I tried outputting some AVI files

    first one was in a lossless codec named
    Lagarith
    mp2 audio
    DirectShow decode is enabled

    Resolution is the same
    FPS is 60
    Bitrate was set to 9600

    The result is exactly the same, but this time the audio is fine.


    I did more tests and get the same results.


    Is there any other video converter out there that can resize the resolution, and change the file type without giving the video artifacts like that?

  11. You can't expect good results scaling 256x224 to 1280x720 . It's going to look like garbage no matter what you do

    If you can, try playing and recording the game at a higher resolution

  12. There is a special AviSynth filter called PointSize (hq2x(), hq3x(), hz4x()) that can enlarge un-antialiased graphics with smoother lines:

    Probably, but that's probably because of how the encoder stretches it. I would at least expect a bilinear blur, but artifacts?

    I tried not changing the size and there's still artifacts and pixel blurring.

    Again, artifacts tend to be caused by settings.
    Without full details on those settings, we have absolutely no clue why you saw what you saw.

    We're going in circles.

    It may also be simple enlargement of existing artifacts.

  15. Yes, it's impossible to say what, if anything, is going wrong without seeing some samples. Post PNG images of the source and the resulting videos. Or even better, short video samples.

  16. and don't use youtube, because youtube re-encodes - so we couldn't tell if youtube is causing issues, or if super is causing issues or something else
