#Ova series
RELATED: Beigoma: The Centuries-Old Origin of Beyblade OVAs Can Enhance Or Surpass the Series They're Based On This usually results in OVA adaptations being closer to their manga counterparts than the network anime versions. Not being on a television network also allows for a slower pace, greater characterization and storytelling, as well as the ability to showcase content that might otherwise be censored.
Likewise, OVAs boast much higher budgets than mainstream televised anime, resulting in significantly greater production values similar to that of actual movies. While OVAs can sometimes be official spinoffs, sequels or prequels to an anime series, they can also be non-canon to the show's story, or entirely original works with no previous source material. Usually - but not always - longer than one episode, OVAs have a wide range of runtimes, from small, bite-sized segments to even a few hours, though it's more common for them to be around 30 minutes long, like a televised episode of a show. Similar to the straight-to-video market in other countries, they were originally released as VHS tapes then DVDs, and more recently, Blu-rays, giving way to the term OAD (original animation DVD) to come into use.
OVA is an acronym that stands for "original video animation," with the first arguably being 1983's Dallos. These productions, as their name suggests, are tailor-made for home releases and are not screened or shown in any other format prior to this.
