C100: Artifacting at the start of each clip

AVCHD is non-professional recording format.
It's suitable to deliver for YT, but not for professional type of work at postproduction. It's primarily the distribution type of compression in this lowend form, it's used at amateur camcorders only.

Use ProResHQ or Avid DNxHD185 codecs, there are no compression artifacts.
( It doesn't matter if the AVCHD codec is a little better or worse, this codec is not suitable for full professional type of work. )

Do you see this when you view clips in your NLE? I see this if I play clips back in VLC or Windows Media Player but never in Premiere Pro.
I've shot many productions with spanned clips and internal recording and never had an issue.
 
as always, post as many settings as you can recall so that folks can better help.

what framerate, what card, oem vs non oem battery, etc... and how long does this artifacting occur for?

Same here. It takes VLC a moment to "catch up" when viewing these files, but I've never had this happen in an NLE.

Also, I use Canon's Data Import Utility to transfer my files from the card. It's not a necessary step, but I like that it automatically spans my longer clips, which helps me manage my files.
 
I have noticed when I use Pre-Record, the first frame is often artifacted but I've never had any bad frames in the middle of clips and I mostly work with internally recorded files.
 
With long takes, one continuous clip is split into multiple ones around 15 minutes. This artifacting only happens to me when i import the .mts files individually rather than importing the whole card file structure into my NLE.
 
That is some shitty artifacting.

I don't know what's causing it, but I've never had a problem before and I've only been shooting avchd internally. So... it ain't that.

I was also recording ProRes, but this is hardly a solution. When I'm using AVCHD, it's usually for long form web stuff - conferences and such. I don't want to be handling 200GB per day. ProRes is very inefficient.

This did the trick. Thanks!
