You want to make your videos yourself?
Look after these details and your movie will make a difference
You need a good quality external microphone. Can be low cost, but it has to be fit for the job. You’ll probably want a lavalier microphone. Lavalier microphones come in all sort of price and make. The mic must be really close to the source / the voice. It must be somewhere near the neck or collar of the talent.
But first, listen to the soundscape. Give it a few moments. Ventilation noise, road noise, neighbourhood noise? Sound of the room too resonant? This can guide you to a (more) suitable place. More here
Transmission & recording of sound
By design the camera is located outside of the frame, but the microphone must be very close to the audio source, the voice in our example (hint: for voice, camera sound never is an option). Thus, as your video camera/smartphone will be located a bit away, the question of transmitting the audio signal to it then arises. Three examples here:
V1a. Long cable, with lavalier (omni*) mic, for DSLR, Rode Lavalier & Rallonge Micon-TTRS & Adapter SC3
V1b.Long cable, with lavalier(omni*) mic, for smartphone, Rode Lavalier & Rallonge Micon-TTRS
V2. Wireless transmission kit, with omni lavalier and all cables needed, Shure FP15 + Cardioid Capsule WL185
V3. Local recording, sound file assembled with video later during post production, Sennheiser Memory Mic,(omni*)
In very quiet environnement, omnidirectionnal mic can be ok.
In noisy situation, go for a cardioid mic with directional capabilities.
For V3, a second smartphone (very) near the talent’s voice, in his front pocket upside down or with a lavalier microphone connected works. (Remember to start the recording though… in a voice memo or iTalk app.)
Be aware that with solution V3, you are left with yourself for synchronising sound and picture files in post processing. So a Clap at the beginning of each take is required and will make it easy to locate the exact corresponding moment both in the video and audio track.
