2nd, there is a CS6 Bug with spanned AVCHD http://forums.adobe.com/thread/1004369?tstart=0
I will have to try this import technique on the next project.
If the 2nd issue comes into play (AVCHD/CS6 Bug) would my only recourse be to convert my MTS files into a different video format that will allow for seamless connections?
I read somewhere (don't have a link) that Sony has an included (with camera) utility program that will make a seamless join of AVCHD files
You might check at Canon's site to see if they have a similar utility
good point... I think I found something on the topic of Canon Camcorders which has been published by Adobe - http://www.adobe.com/content/dam/Adobe/en/products/premiere/cs6/pdfs/adobe-premiere-pro-cs 6-canon-workflow-guide.pdf
That PDF mentions a Canon XF Utility, which might do the same as what I read about the Sony utility program
I've never used that Canon program (I don't remember it coming with my HFS100 camera) so don't really know
"offers various options for managing and playing back clips recorded with Canon HD camcorders compatible with MXF files, including the EOS C300 and XF-series cameras"
So, that let's me out... the HFS100 produces MTS files
My Canon Legria (PAL version of Vixia) HF S30 came with some Pixela software for transferring the files from the camera memory to the computer hard drive. I use the Transfer Utility, which I believe will do what you want with spanned clips. The software came on a CD, but can be downloaded.
