Add Audio to Video

Job ID: 34580973

Budget: £10 – £20 GBP

I have a video file shot on a Canan Camcorder XC15 in .MXF format but the audio didn't work. I also shot the same piece of content simultaneously on my phone in .mp4 format which has both the video and audio. Is it possible to overlay the audio recorded on my phone to the video shot on my camcorder?
