Im thinking about submitting a speedrun to the 100% category of jak and daxter 1 (I recently created my account so at this moment i may not be able to submit any runs) and i dont have a capture card so i was thinking of taking a video with my phone and having a second screen in the background showing my splits and timer. Would this be allowed. (My last time (unrecorded) is actually pretty bad at 4 hours 35 minutes so im wondering if i record my next speedrun with the above strategy inacted if it would be acceptable) Also due to not wanting my voice heard i would prefer not to have audio, would that be acceptable? (Im asking if not having audio is acceptable as if it is then i would not have it, however if it is required to have it then id have to make due with random noises being heard.)

Every game has its own rules for acceptable submission. Check the rules for the category in question and consult with the community for the game if you have further questions about submitting your runs.
