Well OK - could it be framerate differences?

My camera is set for AVCHD 16x9 60i video (I am in the USA.) I figured it was best to set the camera (Panasonic GX7) to record video at the highest data rate, and this seems to be it.

Vegas (actually Movie Studio Platinum 13 - it will always be Vegas to me) said my project properties were AVCHD 1920x1080 29.97 fps. So when I rendered final output I said to use the standard AVCHD 1920x1080 template. This produces MTS2 files, which I have always generated before.

However, during playback on my HDTV (and on my PC too) I noticed the framerate was not right - things were happening too fast. So I started looking at how to make sure the input & output framerates were the same.

I found that I could get the input (project properties) framerate to be 59.97 by clicking on the little button that lets you point to your input video clips. There is no option I could find to select this framerate from a list.

After doing this I specified AVCHD for my rendered output and then tweaked the AVCHD 1920x1080 template to specify 59.97 fps. I have saved this tweaked template and now am using it to re-render all my projects.

I've used MediaInfo to verify that the framerates etc. on both input and output videos are the same. So hopefully I've got things squared away now - at least the random crashes & hangs are no longer happening.

60i = 29.97i=29.97 fps, 59.94 fields.
30p=29.97 fps

I still say that's pretty inconvenient. What do we call a 60fps interlaced format? 120i? No. 60i should refer to 60fps interlaced. 30i can certainly stand for 29.97fps interlaced/59.94fields just as well as 30p can stand for 29.97fps progressive. Then again, 30 really ought to stand for 30, not 29.97, since 30 is just as valid and useful a frame rate as 29.97.

Yep, and it's all for legacy reasons, when people didn't understand their nomenclature would become obsolete.
Of course, (30*1000/1001) was a confabulated number in the first place . . .
;?)
