The main difference is that a studio is using a fixed venue where the filming will be done. A production company can work in, or at, a variety of venues which may include a studio. A video crew from video production companies in Johannesburg can go anywhere in the Gauteng or across the country. A studio may include green screen filming or a complete set. In the film industry, a studio called a “sound stage” is often used. The studio is actually for filming and not specifically for sound but it is “soundproofed” so there is no outside audio interference. This means that the sound recorded while filming will be cleaner. The sound studio on the other hand is rarely filmed and only the sound is recorded there. The one exception is where an audio recording is filmed for example for a music video. A production company, on the other hand, can include all types of filming and sound recording on sets, in offices, or almost any other venue. This includes animation. They can also use all the facilities available to studios. Often studios and video production companies work together or subcontract each other to complete their projects. In some cases, film studios are dedicated to specific TV shows or programs. Each studio may have only one program they are working on or can be open to a rotation of programs. In some cases, the studios are open to public and business use.
