Hi,

thanks for your reply!,

I built it in after effects, exported as a quicktime animation lossless .mov at best quality and 16 bit deptth per channel. I then took it into adobe media encoder and used vimeos recommended setting to export as a h.264 mp4 with 2pass VBR. I uploaded it to vimeo and now it looks awful. all that purple background was, was a colour change applied to a solid so that it would go from dark blue to purple just after the shatter effect.

Why would that simple colour change be so blocky??

thanks

Hi all,

Does anyone else have any ideas? Ive tried Teds suggestion to upload a CBR but then this means im not able to use 2 pass VBR, which lowers the quality. Another thing worth mentioning is i have another animation that this sort of thing happens on too. Its the feathered part of spotlight on a green solid in 3d space. They both can look fine one moment then look awful and hour later. 🙁

thanks,

Greg

thanks Ted!, ill try that.

hi,

im viewing vimeos re encoded version. is it something to do with bandwidth dipping up and down?

thanks,

[Greg Howell]

thanks guys!

one last question.. the most annoying thing about this is that ill view it, and it will be fine, then an hour later ill come back and the quality would of dropped enough that you will see blocks of colour in one part of the video. whats happening? – this makes it really hard to test how good it looks with each setting.

cheers,

Greg

it’s started to happen again. its no where near as bad as it usually is, but here’s an example..

..notice the streaks of colour coming from his arms.

This is what’s adding to the frustration; it looks completley fine now, but then ill watch the same video in an hour or so, and one part the movie (a fade from one solid colour to another in the background) will just look terrible. You know those blocks of artifacts you see sometimes?.. A similiar thing happens on youtube too. Why would it look fine now, then fall apart an hour later? – it doesn’t make any sense.

also i have a quick unrelated question – is the animation lossless codec in after effects truely lossless? i mean is there any loss of information at all. And will it export a 16 bit project, or just 8 bit as default?

thanks!

hi there,

Thanks for your reply! I’m not using media encoder, as its not working. I am exporting directly out of After Effects. I’ve tried vimeos recommended settings (1280 x 720, 5mbps ect..). most of the video is fine, but i get these horrible bands of rings for my vignette, and at one point in the video there’s a few frames of random blocks of colour (like artifacts). to make matters worse, the artifacts arnt there once the video is uploaded (it looks fine), then ill return to the video an hour later, and the quality has fallen apart!- how is that even possible? is this a data rate issue? if so how do i reslove it?

..and yes, its fine before uploading. I also get the same thing on youtube too, just not as bad.

id appreciate any suggestions.

thanks.
