the Video test is also not so good for Jpeg2000.
on vfx shots, graphics that tend to be pretty short on Alpha, QT Png is my best bet for now and the test confirms it. Quality test: Exactly the same scanning for Luma/Chroma Changes or Noise Levels at 1600%Īs you can see Png wins here in terms of file size on Alpha - almost half the size. Vfx on Video Footage in the format of MXF 10bit - we will call this Video All Graphics on Alpha - We will call this GraphicsĢ. if we are talking about the same Jpeg2000 (choosing Quicktime and on Format Options choosing Jpeg2000 - 100% Quality), I made another test on a recent project in 1920x1080 Composition with two types of Footage, Rendered as 8-bpc (there's is not 10bpc for these codecs):ġ. if I need a D.I but to be the smallest file size and render time and it's not a graphic I will try PhotoJpeg 100%. if I need HD for delivery to an editor, 10Bit, Alpha or No - I will give him DNxHD.ĥ.
and if it's on Windows I will give them the installation file.Ĥ. if I need High Res (above HD) D.I for delivery to an editor - I will use MagivYUV. if I need proxy or preview of a high res composition- I will render Photojpeg 75% or Jpeg 2000 and set resolution to quarter.ģ.
if it's in a server based environment where I need to deliver fast - QT Animation.Ģ. if I need to deliver 10 seconds of graphics on Alpha on the Web - I will use QT PNG. thinking to work with that instead of Photojpeg.ġ.
it does have Alpha and 10Bit but did not run full tests.
on Windows you do need to install the codec (it's free).
Tested with 3:33 minutes of compressed MP4 Video File 2880x2880. this is a comparison table but not taking into account the Alpha. the downsize that it will render the slowest.
