I have a GoPro Hero3 Black. Putting 1080p60 files on the timeline and playing is simply awful. Very low frame rate. Okay high bitrate High profile AVC files are hard right? Well no so fast. I downloaded a Panasonic GH3 1080p60 clip and it plays just fine. It is actually 50% higher bitrate than the GoPro.
Both are listed as High profile level 4.2 using CABAC encoding. What could the GoPro be doing that causes Vegas to choke? Deblocking filter enabled? Mediainfo shows the GoPro is using a canned IPB sequence and the GH3 does not. Can that matter?
The GH3 plays at full frame rate, Preview Auto (which happens to be half).
The GoPro starts at about half frame rate but slowly deteriorates to a few frames per second as it continues playing. That has nothing to do with file position. It always starts about half and deteriorates.
Since the GH3 generates a MOV file I used Avidemux to mux the video into an MP4 file to get quicktime out of the picture in comparing GoPro to GH3. The video stream was simply copied to the MP4, not re-encoded.
Using Media player classic, either file plays just fine at a similar CPU percentage. Vegas seriously dislikes GoPro files.
A lot of GoPro's out there and we action types like the higher frame rates.
Anyone know of a video stream analysis tool?
If you are interested in investigating.
Here is a link, 270MB, with a zip file containing a GoPro and GH3 1080p60 clip and a VEG file. No effects, project matches source properties.

edit: Updated files. Recorded new GoPro file as some did not like that avidemux was used. VEG includes a clip for an XAVC-S media. You can render this yourself from the GoPro clip. Saves download size.
