Upscaling, preserving Image Quality

Feb 12, 2013 11:30 AM

Tags: #effects #upscaling #imagequality

     I had thought from reading previous postings (PPro CS4?, 2009?), that the transform effect was superior to using the motion (fixed effect), when upscaling video.  I have found the exact opposite using Premiere Pro CS6.

     I examined still images taken under the following conditions...

     Project is DSLR 720p 60fps with edit>pref>default scale to frame size - enabled.

     Sequence is 1080p 30fps upscaled to 150% and also 160%. 

     Frame captures were TIFF. 

     The 150% case is really a straight crop rather than an upscaling, (720x1.5=1080), but images scaled @160% showed the same degradation using the transform effect compared to the motion effect. 

     Has anyone else had similar results?  Maybe under other conditions, upscaling using the transform effect, is actually best.

    Upscaling always means quality loss.

    Download the trial of Red Giant HD Instant and see if that is any help to you.

    That's confusing data.  PP no longer has Project settings like that, as you can have many sequences with various settings in the same project.

     

    So...which is it?  720p/60 or 1080p/30?

         It's 1080 media in a 1080 sequence in a "720" project.

     

    What I'm saying is that there's no such thing as a 720 project.  There are no project settings for resolution or frame rate.  Those are all sequence settings now.

     

    You're saying you have a 1080 sequence and 1080 media.  So I don't understand where the 720 comes from.

    I used 720 for my project.

     

    Again, there are no resolution or frame rate settings for a project.  What you chose was a sequence preset.

     

    So now the question is, are you using a 720 sequence, or a 1080 sequence.  You've claimed both so far.

    it is importont also to check if your sequence is:

     

    -> Programm monitor is to set to full resolution

     

    a) set to "Render in maximum quality"

    b) set to "Render at maxiumum bit depth"

     

    c) if you are using Adobe Mercury Playback Engine MPE in GPU mode all scaling is done with Lanczos3 that will result in sharp high quality scaling by default...

     

    -> Would be interesting to see differences from older effects that are not GPU accelerated - but I would avoid them because they are too slow to render...

    in a 1080 project

     

     

    Third time. There's no such thing at a 1080 project anymore.  It's a 1080 sequence.

     

    Sequence, sequence, SEQUENCE!  Write that out 100 times on the chalkboard, Bart Simpson-like.

    Were it possible to change this setting in the middle of a project

     

    You can, but as always, it only affect newly imported items, not those already imported.
