the microphone on my computer is broken so i would like to know if doing runs on a phone or otherwise a mobile device would be acceptable (i assume they are but i suppose it doesnt hurt to make sure)

so i am trying to submit a recording of a 5:39 in the category "195 states recognized by the un" but i cant upload it to youtube. so basically the filesize of the recording is 426 megabytes. although thats not much of an issue, for some reason youtube studio literally does not work on my computer (it just shows a blank white screen and never loads) and trying to download the video from its google drive copy on my phone doesnt work either (the download gets corrupted literally every time i try to download it). so basically what i am asking is if google drive is an acceptable website to host a video on? if not then i guess i have no method of submitting it
