Hello,

i am struggling to get a good export out of premiere for a film shot on the c300. There is blocky compression, banding and other compression artefacts present on a mp4 - 24 mbps export. The artefacts are present in darker areas and/or areas with masking. Is there any way to reduce these artefacts ? Please help

You may want to try the X264 codec using MPEG StreamClip. Both are Open Source.

I made a brief little tutorial (tutorialette?) for some people in another forum, but it should get you started:

I wouldn't export into H264 if you had the option to deliver into other formats. If its web delivery, Youtube will destroy it regardless, with vimeo being the best bet at the moment for maintaining quality. You could upload a 100MB/s H264 into youtube and it would ruin texture and create compression blocking in the darks regardless.

Assume this is for web delivery?

Matt - i am talking of an export straight out of adobe premiere

Justin - Not for the web but a hd copy for festivals @ 24 mbps striaght out of premiere

thanks for trying to help guys

If you use some noise reduction at post, delete this. If you can, use an uncompressed version for any renders during postproduction (effects, color correction). If you can, try slow rendering to H264 with x264 coder.

For big screen on festival is much better to use the c100 with ninja2 recording (ProResHQ or DNxHD185), it is the best start point for good result in black on MASTER output. The input quality of all clips is also the most impotant part for good result at post.
