sound desync

Hello.
I use Blackmagic to capture video with sound. At the input I have 1080i50 and at the output for streaming I set it to 1080 PAL 25 FPS. After 3-4 hours of streaming, the video begins to lag behind the sound by 3-5 seconds. Please help me how to fix this problem. Broadcasting 7/24. Thank you.

Few quick fixes to try: Ensure proper ventilation to prevent your Blackmagic device from overheating. Lower the video bitrate or resolution slightly to reduce processing demands. Check for software and firmware updates for your Blackmagic equipment, as these can often fix performance issues. Adjust your buffer settings in the streaming software, which might help synchronize the audio and video.
