In recent decades, telecine has primarily been a film-to-storage process, as opposed to film-to-air. Changes since the 1950s have primarily been in terms of equipment and physical formats; the basic concept remains the same. Home movies originally on film may be transferred to video tape using this technique, and it is not uncommon to find telecined DVDs where the source was originally recorded on videotape, or shot on film and then edited on tape. Movies and TV shows that were originally shot and edited on film, or digitally, are more commonly put on DVD at their native frame rate with flags that tell the DVD player to perform pulldown on-the-fly.
