Here is a list of things to get your creative juices flowing.
Video FX - animations
For a normal Vlog style filming, pretty much out of the question. but when used "tastfully" in entertainment type videos can provide amazing results
Correct lighting
if you are working indors then yes(kinda) - there are other settings within a camera to be able to compensate for poor lighting aswell as aftereffects in editing.
Sound FX
again "tastfully" ...if you can obviously tell its a sound effect or audio overlay the porduction quality is deminished...unless that is the specific goal of the video
Colour correction - contrast, filters and such
Not necessarily required to make a good production depending on your content but can be used to fix lighting issues as stated above. also adds exponential time to editing and rendering of a video. (see awesome possum's video re-edit to one of my videos)
Audio correction - popping, hissing, crackling and such
these should be worked out prior to making a live video, and can cause the viewer to not watch... mic cliping and popping is not something you should have to fix in the editing stage. good, sound and quality audio is something very hard to get perfect. I wouldnt say you would be stealing other's camera and mic set ups, especially if they already did the leg work for you and posted a video on how they did it.
Intro/Outro
creates a good production value depending on the type of intro/outro, but can also be a killer if it's too long for an intro.
Composition - Jump cuts, transitions
normal cuts and fades add to a good production, take note next time you watch TV, how they do it. try to stay away from the off the wall kinds of fades like checkerboards and spirals, they pull attention away from the intended content.
Audio Quality
see above audio correction=)
Video Quality - 1440p anyone?
Unless you have A LOT of money invested in your computer software and hardware, it is going to be hard to even read, process, and render UP TO 1080 or even past 720. not to mention the majority of viewers do not watch the uploaded production past an "actual" 720 resolution to the screen of the computer/TV. as well as having to rely on broadband internet speeds that sometimes cannot load up to 1080 fast enough to keep the target audience waiting, and having them drop the resolution to have it load faster. your video quality is something to take personaly and what suits you the best. I do not shoot past 720p/60 on the gopro, simply because anything higher is harder to edit.
