Ask anyone who knows which video capture card to use. The output card can be synchronized with the big screen in real time without delay.

我采用blackmagic duo2采集卡捕获3路sdi信号输入到vmix进行切换录制,然后从duo2卡第四口出去到现场LED屏幕,出现画面比现场音响声音慢的问题, 我尝试采用电脑显卡hdmi口输出给led屏幕 延时极低,现在一直苦恼用什么卡能解决这个输出延时问题,貌似这个延时不是采集的延时,应该是输出后的延时,为什么用hdmi口就延时基本感觉不到?

vMix 是做不到声音和屏幕同步的。你会发现屏幕会慢大概200ms 要做能同步,需要用硬件切换机,比如Atem之类的。
