Hey Paola, I'm sorry your video didn't turn out. I know it can be devastating when you put a lot of work into something and then have it just crash and burn. And I appreciate your use of humor to get past frustrating moments like this, I do that to! I don't know the specifics of your video that didn't work out, but in that scenario with a short film or something you can do whats called "ADR" or Automated Dialog Replacement. Basically you sit somewhere with a more ideal environment for audio, listen to the original take with the bad audio and then record your voice saying things the same way at the same pace. Then you just replace the audio. It's pretty easy once you get the hang of it. It doesn't have to be perfect, (maybe you can even get a joke out of the whole situation with the voice over) This video sounds like it was really important to you so this is one option for saving it. Let me know if you need any help doing it or have any questions about it. I'm happy to help. Keep chasing that dream, I know it seems sometimes that we've stopped progressing, but if you're trying you're always learning and your always getting better.
