I've wonder if the videos aren't a dangerous way to subject yourself to biases. It's well known for example that people judge attractive people more positively. The same probably goes for a good presentation style. Now I'm sure that being attractive or being a good presenter have some predictive value on startup success simply because everybody has these biases, also the people the startup will later make deals with or otherwise interact with. But assuming that the application judges have the same level of bias as the rest of us, since there are many other factors besides attractiveness or presentation style, the bias would be bigger than its predictive value. It would perhaps be an interesting experiment blank out the names of the applicants and to let half of the judges read a transcript of the video instead of watching the video itself, and see if the judgements are different.
It would be nice if people would put a tiny bit of effort into the video, specifically making sure the audio is intelligible (levels, lack of noise, etc.) on a normal computer. Just playing it back on a normal settings computer on internal speaker would probably be enough. Maybe don't shoot it in a car while driving, or outdoors with wind?
I agree with you, I'm not saying that the video can be low quality because it doesn't matter, just that the content is far more important to them, but yeah, I think is better if you have a proper camera and mic. Wouldn't leave a nice impression if someone submit a video shooted with their phone.
No one really cares about the video quality for this; a webcam is fine, and a phone is probably fine. And overproduced video is horrible. I'd just stick to making sure the audio can be easily understood, and making sure it is about a minute; if there is a lot of wasted time in the beginning, edit that out.
It seems (at least from your HN profile) that you're a founder, not a YC partner, but yet you're giving advice as if you have seen some of the videos that have been submitted by YC applicants. So I'm just curious now... are you or are you not a YC partner?
I'm not a partner at YC (as far as I know all the YC partners who were alumni were from fairly early batches, and also had exits; I have a YC funded company which is ongoing).
The relevant detail here is that I've had ~20-30 people/yr ask for advice on applications, and aside from "be concise and straightforward; emphasize your strengths in every answer; be clear and don't assume people will have the patience to decode some rhetorical trick", "wtf, I can't see your video because you left it as 'private'" and "I can't actually hear your audio" are common.
