footage is pixelated – can someone check if this is normal?
I got some greenscreen footage I am supposed to key. the problem is that the footage is really bad. I can deal with the noise and the grain but I am very concerned about the fact that everything seems very pixelated.
i would really appreciate if someone could take a look at one test clip and confirm that I am not blind. the DP messed up in my opinion. something’s very wrong here.
here is the link to the test clip
thx a lot

nope .it’s not pixelated.
it’s typical H.264 compression.
All u need is some enhancement to get rid of this artifact.
Try Neat plugin or denoiser by RedGiant
But in some cases depending on the composite background u can get a decent key without any denoiser.
Also a deartifacter plugin can be the solution.
check Red Giant Composite Wizard.
good Luck -
I’m with Steve. Footage seems to be o.K. I had to key worse 😉
If you’re using After Effects for keying you could put an adjustment layer with the median filter (value between 2 and 4) applied to it above the footage. Set the transfer mode of the adjustment layer to color and precomp the two layers and then try keying.
The median filter in color transfer mode reduces color-compression artifacts. Most useful with 4:2:0 material like yours.

Apart of a slow drive i think the core is responsible for a choppy
playback, cause i have an Acer Aspire Intel Core i5 which plays my DSLR 1080 perfectly.
Btw y you recommend roto? u don’t talk about garbage masking right?

as long as i remember the shot that florian herweg posted,
was about a guy making 3-4 steps to place him self against the green screen.
So I guess they used a green backdrop as large as they needed
The rest seemed to be a matter of editing, garbage masking and a good key.
So i don’t think they need to do any roto, unless they need to composite a complex shot.
Anyway you are possibly talking generally for the steps of a process, so i might misunderstood. -
OH..ok got ur point.
I’m sorry but i did a quick check on this shot the other day
and deleted it right away, so i don’t really remember the cue point.
But i assume the did a good work on preparation/filming.
So the only thing the have to look after is a decent Key.
Only florian herweg can give us a feedback about. -
