Question: Poor quality after rotation & cannot play on QTime/RealPlayer

Jan 26, 2013 12:47 PM

I am using APE 11., which I have just purchased and installed. I have imported an .avi file (about 600 mb) created on my camera, and then rotated it, after scaling.  I also applied Smart Fix. Two problems: 1. The quality is significantly lower than original and 2. For publishing I do not have an option to select a format that can be played  by  Qucktime or Real Player. The published file is only about 110 Mb. I am new to this, and could not find the answer yet. Thanks  Kurb

    First, what are the specs. of the AVI file from the camera, and what make/model of camera?

     

    When you created the New Project, what did you choose?

     

    Do you have Apple's QT Player installed, and what version?

     

    Good luck,

     

    Hunt

    That information might be very useful.

     

    Whenever one rearanges pixels, and Rotation does that, the integrity of the original will not be retained 100%. However, within parameters, it should not be that bad. Now, if one is adding something else to the mix, like Scaling too, whether desired, or because of perhaps a mis-match between Project and Source Footage, the combo can look pretty sad.

     

    There are just so many variables, that I am trying to throw out any, that do not pertain to your situation.

     

    Also, don't be alarmed if there are more questions, as that is how these things can go.

     

    Good luck,

     

    Hunt

    Hi Bill

     

    Here are the answers to your questions

     

     

    1. Camera is Olympus XZ 1  - 720p @ 30 fps Motion JPEG format.  The AVI specs are:

     

     

    General

    Thanks

    OK, MJPEG, while not an ideal, can usually be edited in PrE, if the proper CODEC is installed. See this article, and read down: http://forums.adobe.com/message/4079377#4079377

     

    Now, with a matching Project Preset, when one does do something, like Roatation, there will be a loss in quality. That loss might be noticed, or maybe not. Again, things like matching the Project to the Source Footage, will be important.

     

    Next, what one does next, with the Rotated Source Footage, will play a roll.

     

    Let's say that one has filmed a subject in the wrong orientation , like a portrait orientation, then wish to use that in a Video, which WILL be a landscape, or horizontal orientation, if all they do is Rotate, allowing the black bars to show, things should be pretty good. If, however, they also need to Scale up the portrait footage, to fill the horizontal frame, there are two operations, and combined, will likely yield poor results.

     

    Just some things to think about,

     

    Hunt

    Thank you for your response.

     

    So if understand this, although avi video that I have plays in PrE, that does not mean it can be edited. In my case the avi cliip does respond to editing in PrE, but you are you are saying unless I have the exact codec that source was created installed on my computer then the editing in PrE may get corrupted.

     

    Also, there is no Project preset that matches the source ie 720p @ 30 fps, so what do I select? , and is this the reason why the loss in quality significant?

     

    With Roation, I don't mind having black bars on either side. I simply want to change from Landscape to Portrait view. If all I do is Rotate, then I lose bottom part of the dancers in the video. To get the whole person into the frame I played with Scale. Is there a better way to achieve this without creating loss.

     

     

    Thanks for your support
