i have a problem with resolution of images.

when i load an image (jpg) into jit.qt.movie

the original resolution comes out modified, slightly pixelated, definitely not the original

I can tell this because if I display the same image with keynote or preview (on a mac) the image looks totally fine

i used interpolation and some settings of the frame size

but this still does not display the right original resolution

i've been through docs and forum and found that it should be something

related to the size difference between jit.qtmovie and jit.window. bur im not sure.

, not with videos (or not that I am aware of).

Dear list
i have a problem with resolution of images.

when i load an image (jpg)  into jit.qt.movie
and display it via jit.window

I can tell this because if I display the same image with keynote or preview (on a mac) the image  looks totally fine

i used interpolation and some settings of the frame size
but this still does not display the right original resolution

is there something I am missing ?

this happens more likely with images
, not with videos (or not that I am aware of).

If you have an image and a very simple patch and an image that exhibits the problem, send it along. OS, computer model and version of Max too.

thanx for answering Ben,
here's the patch


As you can see it is a very low quality image.

Yet when it is displayed by Keynote, Powerpoint or any preview it has the aspect you can see.

When I am displaying via jitter, with the above patch , it does this:

the results are the same.

unless your jit.window has the same dimensions as your source material, there will be distortion of the image.

see if this snippet helps at all. it basically utilizes @adapt 1 in jit.qt.movie to keep the dimensions of the source file, and set the @size attribute of the jit.window.

it looks it works extraordinarily perfect

thank you robtheric
thank you all guys


I have noticed that using this snippet, it will modify the full screen option I gave for displaying jit.window, and obviously the reason is that the snippet resizes the window's dimensions.

Basically now I know the reason why of the resolution problems, and how the snippets solves it.

if I set the jit.window settings to the size of the screen/projector it is going to be displayed ,

using @adapt 1 on jit.qt.movie, it does the trick without having to resize the jit.window every time we load a movie.

hi, i am having issues with this as well. I am trying to display an image which is 1366 x 768 but when i full screen, the image ever so slightly distorts. How can i get it not too when on full screen. I have @adapt 1 on the jit.qt.movie object. here is a test patch.

easiest way is to use opengl, and the jit.gl.cornerpin object with @preserve_aspect 1

i was going round in circles with this, and had found a hack way around the issue (which was actually being caused by the @noaccel 1 attribute.

On my apple machine i didn't need it, but the exhibition was on a windows machine. The attribute was on the patch, and thus causing issues, as i was editing the patch on my own machine. On the windows machine it works fine with the @interp 1 attribute. However your way is much better ad looks much neater with the full border....

jit.gl.cornerpin works fine for keeping the aspect ratio in place.

Thanks Rob!

Thanks also here, the Rob technique and patch worked fine for the quality, finally !

However, Rob put "5" in the qmetro objetc, why this number ? Is there a a reason ?

If we put a greater (or lower) number, can it smooth out the playback even more ?
