Visually:
- Bad lighting. Natural looking bright light is best. Dim yellow light or red light isn't as pleasing to the eye unless it's a mood meant to add mood to the video. Some shows on HGTV still haven't gotten this point down yet.
- Bad angles. Vloggers should usually aim to have the center of the shot level with their eyes or slightly above that 0 degree line and facing down. When it comes to more cinematic videos, the angle should help accentuate the shot.
- Too close. Some people have their face right up in the camera and make it feel claustrophobic.
- Too far away. It is also very possible to be positioned so far away that it just doesn't work.
- Too much shaking. The camera should be as steady as possible, or if possible run through some sort of stabilizing program.
- Not prepared to be on camera. Dress nicely and do your hair... Get good rest (ie beauty sleep)... Look as happy and bright as possible. I think that's a given. Unless you're a daily vlogger capturing your life, or unless it makes sense to not be prepared. For example: Vlogging about how you got isht wasted last night and you're hung over. You can get away with it then.
- Our of focus. If you have a camera that focuses, make sure it's focused on the right subject. DSLR users, I'm talking to you...
- Not showing someone you're talking to. If you're vlogging, and you're having a long conversation with someone, they should be seen (unless they don't want to be seen). Either turn to them every now and again or get them in the shot. It can (for some people) be annoying to only see you while you're conversing with someone else.
Audio:
- Background noise. In certain settings, try to limit or eliminate background noise like cars outside or people talking in the background. Many settings (like vlogging on the go or outside) you can't do that, obviously. But if you've got a clean recording corner or something (like iJustine's couch or Colleen's corner), try to not have busy backgrounds.
- Noise. Unlike background noise, noise is the hissing and popping that some microphones catch. You might be in a perfectly quiet room, but noise can still be picked up. Minimal noise can be ok, but some microphones are more static noise than recorded audio. Try to get a good microphone, and if you're still having issues, try using a program that cuts noise.
- Wind. I don't even know how to cut wind, but I hate it. It's terrible for film. It needs to just go away!
- Too low or too high. Try to set the audio level roughly equal to the audio levels of similar genre videos. This can be difficult.
- Unbalanced voice and music. You should be able to hear the subject over the music, but the music shouldn't be so quiet you can't hear it without straining. I'm learning that Windows Movie Maker SUCKS for audio equality... Also, anything I make in Windows Movie Maker is too quiet for macs... ... But I think this is just a me thing...
- Electronic interruption. Cell phones and other electronic devises sometimes cause interference with audio devices when they're too close. Make sure this is not happening. It might be best to turn the phone off.
- Higher decibels than your microphone likes. Microphones are sensitive. If you get too close or too loud, they get a static-y disruption that can ruin the audio quality. Keep a good distance from the microphone.
- Echo / Reverb. If you're in a cave that's one thing, but don't vlog in a big empty room. Just saying... Shane Dawson does it, and it makes me want to punch him in the throat ^u^
Presentation:
- Umming and stalling. Unless your vlogs are meant to be long and drolling... try to to practice not saying um as much, and if you can, cut it out in editing.
- Sentence running. If you do stationary vlogs, it helps to punctuate sentences or paragraphs worth of talking with a pause just in case you make a mistake. I know I fumble on my words a lot, so it helps to slow down and talk clearly. Not everyone has this problem, but it can make a big difference.
- Not involving the audience. If you're a vlogger, it can be annoying if you look around the room instead of at the camera.
- Acting like you don't want to be there. I've seen a lot of vloggers who act like they're being forced to make their videos. They have a certain attitude that says "I don't want to do this, but I'm going to, and I'm going to do it my way, and fk you." ... It's not appealing.
- No energy. I struggle with this often, but I can't stress how important it is to be chipper and happy when you make a vlog. Unless, again, it's about how you got isht wasted and you're hung over, or unless it's sad: Try to have a positive or at least up-beat neutral attitude. People will be more interested if YOU seem interested. It can be hard to do, but... try.
- Bad posture. >.> I don't think I need to elaborate on that.
Many of these points are opinion. You don't have to follow every one to a T. It's ok to slip up. I'm TERRIBLE at these. In fact, I used my own videos to draw a lot of these points. So I'm not professing that I'm any better myself, just that I understand the principle.
Also, a not on resolution. ... We need to get over this whole resolution thing. Not everyone can record in 720p. Not everyone can record 16x9. But I've seen a lot of low resolution videos that are fricking amazing. So... BTFD people who have problems with low res. ^u^ Just saying.
