在英语中，如果你想表达进行妈妈视频通话，可以使用以下表达方式：
Have a video call with mom.
Talk to mom via video call.
Have a video chat with mom.
Talk to mom on a video call.
例如：
I'm going to have a video call with mom.
I'm going to talk to mom via video call.
I'm going to have a video chat with mom.
I'm going to talk to mom on a video call.
希望这能帮到你！
