Audio for video does not have to be expensive but it does require thinking through the needs of the particular session. Getting mics close to the source trumps any sort of long distance pickup. Shotgun mics are often thought of as being able to have "reach" like a telephoto lens but that misconception can lead to frustration. A shotgun mic is one with a very narrow polar response and just like any mic, has a better signal to noise and reverberation field ratio when close to the source. Their advantage is high degrees of off axis rejection. The can lower noise, and stray sounds if you also want any off speech or action sounds to also be rejected. For example if there is more than one person in a scene, a shotgun mic will result in a big difference in both level and tone character between different speaking talent. Getting close with a bad mic will often sound better than a great, $5000 mic from a distance. Getting close also sounds more realistic in that it is closer to being in sync with the action. Sound travels approx. 1100 feet per second so miking an event 100 feet away will be out of sync by 90ms. We notice delays of about 30ms or greater and our brains start to cut the implied connection between the sound and the image. Tiny sync differences between lips of a lip-singing performer and the sound we hear is irritating and distracting, taking away from the intent of the production. Amateurs often rely on camera mounted mics and ignore who when they zoom, the sync changes and the audience is distracted. Getting the mic close and off the camera takes care of that. Wireless mics can be quite useful and can be had for a modest amount,although some can be thousands. The two weakest parts of modest productions is panning/zooming and poor management of the sound. Neither one needs to be solved with expensive solutions if the needs for a particular session is addressed directly and creatively. Most often, one size does not fit all. Gathering a collection of different audio tools like pressure zone mics, lapel, boom omni(non-directional), cardoid(heart shaped polar pattern) or hypercardoid mic(shotgun), reflector mics and their booms, fish poles, stands, wireless packs, various cables and extensions, a mixer, gobos and isolation panels,and adapters can all be low cost or some homemade yet return excellent results if applied creatively, closely, to the source and its acoustic environment. Having a dozen totally different $4-20 mics and homemade gobos will deliver better more pro results than a $5000 mic used applied haphazardly. Electronics such as mixer and recorder are pretty high performance for reasonable prices, so don't be too anxious to get the popular high priced video oriented mixers. A $80 Behringer will do well and few people could hear or even measure a real difference between it and a $1500 video specific model.
Rode started by importing a very low cost Chinese made condenser mic element, about $5, and mounting in a case that looked something like some classic old German mics and offered them for $300 or so to the exploding home recording and hobbyist studio customer base in the late 90s. A lot of other companies started making mic with those large diaphragm elements. They never really were a pro mic manufacturer but developed a good following with hobbyists and amateurs who could not spring for a higher quality mic. They really got a boost from getting into the home video market early so most the newcomers assumed the company was producing quality audio gear. I doubt you would find their mics in real recording studios, broadcast, or scoring stages. Some of the little pocket reorders are excellent with better specs and performance than was available at any price for the first 60 years of the recording industry. Buying one aimed at the video industry will be expensive but one with very similar specs might be only $130 for a model aimed at the musician market. Just like with photography where skill, a compelling story and resourcefulness trump high cost gear any day in creating something people want to view, sound for video is exactly the same.
