Grain may be less visible in media player due to smaller resolution of playback, smaller window, any number of issues.
Grain can only be inserted during compression if improper compression settings are applied.

More valuable information is :
What are you rendering to?
Resolution
Bitrate
Codec

The kind of card isn't relevant, FWIW.

try transcoding the GoPro footage to match your timeline settings or change your timeline setting to match the GoPro footage.

u can use mpeg streamclip to transcode it

Transcoding is foolish when using Vegas or Premiere.
Matching timeline settings won't affect a final render.

768kpbs is the problem.
You're taking an 18Mbps stream and cutting it down in size to almost nothing.
Change out the bitrate/use a template with a higher bitrate. 6Mbps is a good average, 10Mbps is a good max
