Facing Flooding Issue, Multicast traffic from VLANS and Trunk Ports on Cisco Switch

Hi
I am new to cisco switches and need help for cisco switch multicast data through vlans and trunk ports.
I have multicast data from video encoders and I want to pass it to another switch using trunk port.
I used simple vlan and trunk port configurations to pass the data to other switch but I am facing flood and full port bandwidth usage on trunk ports.
My current scenario is:

Switch 1:
PORT 1 = VLAN 100 = VIDEO ENCODER GROUP 1 (Connected with Video Encoders),
PORT 2 = VLAN 200 = VIDEO ENCODER GROUP 2 (Connected with Video Encoders),
PORT 3 = VLAN 300 = INTERNET DATA,
PORT 48 = TRUNK.

Switch 2:
PORT 1 = VLAN 100 = VIDEO ENCODER GROUP 1 (Connected with IP QAM),
PORT 2 = VLAN 200 = VIDEO ENCODER GROUP 2 (Connected with IP QAM),
PORT 3 = VLAN 300 = INTERNET DATA,
PORT 48 = TRUNK.

 

The issue is the multicast packets are flooding and using complete port bandwidth and network performance gets down.
On trunk ports the bandwidth usage gets full to its port capacity due to multicast flooding.

Anyone can tell me the configurations needed in cisco switch to pass the multicast data without any issue from the cisco switch fulfilling the above scenario?
Thanks.

 - Depends could be that the multicast setup on the switches was incomplete resulting in unwanted flooding. Have a look at  this thread for starters :
