Greetings bkostic82,
I am sorry to hear that you are having issues with the footage recorded on your EOS C70 camera. It is an odd glitch and does appear to be coming or appearing on the left half of the frame. It almost looks like an encoding issue with the file. Per your description, you have tested the footage by viewing it in both Davinci Resolve and in Adobe Premiere Pro. If possible, please test to see if this glitch appears on the footage when playing the video back on the camera's LCD screen or in a different video player on a computer. I understand you are using a specific brand of memory cards, but please test to see if this issue occurs when using a different brand of card.
In case the issue persists, then we would suggest on sending the EOS C70 camera to our service facility.
