Fix 5Dmk2 pixelization or jitter in high detail 1080p-30 nature shots?
Hi, I’ve been shooting 1080p-30 lake/nature shots with a 7D with great results, now doing similar shots with 5D and seeing (jumpy/pixelated/jitter?) in far-off foliage mostly when far-focused. Tried backing off sharpness, still seeing it. Links below to a couple of 1sec clips (7mb each).

https://files.me.com/stephenunderwood/5a8u2vWill transcoding from H.264 to ProRes422 help this or is there a plugin that will smooth these areas out? Any help is greatly appreciated.

It’s most definitly an aliasing issue, don’t think transcoding will help.

I don’t know any plugin, that is smoothing out areas automatically, I think you’ll have mask by hand… But maybe someone else has an idea…

Maybe a case for Canon Service. We had a sensor cleaned by Canon and they left the ISO setting as ISO 6400, not Auto after fixing the issue. But, if it is video that problem should not exist, but, check your video speed to say 1/50 sec and not too much faster as recommended by Canon. Our 5D Mark II’s do not behave that way ? Been using them for 2-3 years.
Good luck !
It may be best to use an Image Stabilized Lens ? I transcode to Microsoft avi/uncompressed, there are no compression artifacts , and mostly export to tape at 1440 x 1080 HD or Blu-ray either H.264 or HDV/mpeg-2 , there has been no quality issues with either method, using Premiere Pro or Sony Vegas. Even Premiere Elements 4.Ie., PAL @ 25 fps only
