Online compression with NOISE effect
Hey guys, I have a video where I’m applying some heavy NOISE in Premiere CS6 to the clips directly, as each clip must have a different level of the effect on it. This is merely an artistic choice and has to do with the nature of the content…
No matter how high the quality when I export the sequence, the encoders on youtube and vimeo seem to have a problem with the noise effect and it turns into macroblocking and other large artifacting problems. Some shots fair better than others, but basically it looks like the encoders gloss over the noise filters and it just winds up turning some shots into jelly.
Is there any way around this? I read somewhere about NOT applying the noise to the clips directly, but using an intermediate, but I’m not sure how that would change anything in the finished export?

That’s going to happen. Noise kills compression efficiency, and when your content is re-encoded to an enforced bitrate, the quality will suffer.
To faithfully reproduce the noise, you may have to encode to a high bitrate and host the file yourself.

Thanks for the reply. I was hoping that wasn’t the only option, but it makes sense.
I have seen other videos on vimeo that use similar noise fx. I contacted one to see what filter he used and am hoping he gets back to me.
