It depends on how proficient you are. There are people who are proficient at English but have an accent, I think they will be okay. But if your ability to speak English proficiently is rough, it could hurt you.
However, people look at the whole presence on video. It could include body language, your personality, your voice, the persona you choose, etc. It really depends.
But also remember English has many variations. There are the U.S., UK, Australian, Canadian, New Zealand variations. The world is becoming more international so your chances are better now than 10 years ago.
However, I won't lie. There will be some people you will never win over based on your speaking ability. The only way to know is to try a few videos and see what happens.
