The new video released Saturday shows violent exchanges between bikers outside the restaurant's patio. The clips released in October showed the scene on the patio and inside the restaurant.
In both cases, CNN did not disclose its source for the video.
The most recent release closely follows an Associated Press report that four of the bikers killed were hit with the caliber of bullets Waco police fired that day.
In connection with the shootout, 186 people have been arrested, and 106 have been indicted by a McLennan County grand jury. The remaining 80 cases will be heard by a grand jury, McLennan County District Attorney Abel Reyna has said.
