Q: apple Prores is jitter on osx10.6.8 but 10.7 or 10.5 is not

Hi Michael, thanks for your time

actually it doesn't matter what settings you have on fcp or after effects or any software because just playing the quicktime in quicktime player it looks bad.

at first I thought like you do, and I was driving mad changing setting on prores sequences until I give up and choose this codec just for offline editing. and believe I'm having this problem for about 1 year now so I tried everything.

but today someone send me a 4444 prores file to add to an ending of a tv commercial,

you can easy see the jittering on the borders of the text and graphics on Osx10.6.8 at quicktime player.

I ask for a better quality file and they told me that they used prores for onlines and that they can see it ok. so I tried on my notebook with 10.7 and boom it looks perfect then I went to an old G5 with 10.5 and it looks perfect. but in 3 others mac with 10.6.8 it look awfull  (the ones that we use for edit) . this test was just hitting play on quicktime player.

I would love to use prores for high quality editing and I can't don't want to update everything to 10.7....

it should be any fix,

yes I know.

we do have blackmagic cards with video monitors. and of course you can see the jitter there too.

the question is why it looks awfull on osx10.6 and it looks perfect on 10.5 and 10.7

the quicktime test is just to get as basic as posible and you can see the big jittering awfull aliasing just on the quicktime player. plus why the same prores 4444 and 422 looks really bad at 10.6 and it's ok at 10.7

sure, I can't send you this file because is a coke tv commercial that we are working on.

but I will send you a test file later.

thanks!!

Hi Michael, I couldn't find your email and I'm sorry I couldn't reply faster but I was really busy.

ok, this is driving me mad.

all of my computer with 10.6.8 are playing apple prores really bad. even playing back thru blackmagic to a monitor.

but the problem I think is in the quicktime player and all this softwares are based on quicktime.

so I just playback a test on osx10.6.8 and osx10.7 and took a picture (I know is not the way but this is a huge problem not a little aliasing or field order problem) just to show you how bad quicktime show apple prores on my computers

I'm uploading a quicktime to my ftp

thanks a lot for your time

yes I will send you that. I see really jagged borders on the red text. is the same quicktime file that the screenshoots links I wrote you early

on the first link, the one that ends with 1068.png is terrible jagged especially on the red text and the more visible is the letter A because of the diagonal.

it reminds me the horrible dv codec
