Thanks Noah. Both images in my computer are from the same computer – why could it read one and not the other? This is just weird. Is there even a place where I can change the millions of colors setting – in preferences – display I see only profiles (and it has my monitor listed.)

I have exported a version with the bit depth looking good at 32 in Pro Res 422. Now I guess I just have to live with the banding when I bring it down

Thanks so much Noah. I am editing in Pro Res now. I don’t have control over the laptop it will be played on so I still want to convert down to h264.

I still have had very strange anomalies with my motion sequence. I have a gradient and I have a generator moving over it (membrane). If I export it out as animation it looks really clean (or if I import project into FCP and then export as animation) but if I go out as Pro Res 422 (I don’t have 444) I get artifacts and banding. I have played with turning on and off dithering. I have been sticking with 8 bits for depth … should I go higher? Isn’t pro res 10 bit (and that isn’t an option in Motion is it?)

Sorry for all the questions but I feel like I am going insane with this. To add to the craziness some stuff looks great when I watch it on the web through firefox but when I look at it on stand alone player it looks like junk (example here https://www.extravaganzacreative.com/Milk/colorspaceIssue.html )

Oops .. the above was meant for my other thread … I still want to know the best compression for quicktime to be given to a company to run off a laptop for a presentation (where I have no control over the laptop and what is installed other than quicktime pro.)

Oops … I replied to my wrong thread (below)
I meant to say here …

Actually this is NOT the H264 bug (or at lest not entirely) I have noticed this is happening in other codecs as well. Still it is only my quicktime players and itunes that are effected … everything else displays fine (reimporting back into FCP, Motion, viewing online through Firefox …)

This is driving me nuts? Is it just my system? Or am I creating buggy videos? I have to get this right! Yikes!

Ok … definitely a codec issue – it is the H264 gamma shift bug. I am heading over to the compression forum to see if anyone has any suggestions I haven’t tried.

Ok thanks a bunch! I previewed uploaded some of my affected files to my website as an example and discovered they look fine in Firefox. So I guess I have the h264 gamma shift bug when playing back. I have wandered over to the compression forum to see if anyone has any suggestions that I haven’t tried yet …

[Jm Knowles]

I can also export it as pro res and then in FCP did a pro res sequence and then exported as pro res. However when i go into compressor and compress to h264 it looks like garbage again. I have gone into the color tab and tried default for encoder and preserve source and they both get the same effect. Grrrr…. maybe now I should be in the codec forum.

[Jm Knowles]

Won’t an animation codec possibly choke the laptop playing it back? I did import the whole project in to FCP but still the same problem when going to H.264

Thanks Richard … that is great to know!
