Videos Layers and Chroma Key are currently only available on devices with supported chipsets. This limitation is due to the specifications of the device chipset, it requires a device equipped with powerful video decoder to decode multiple video clips simultaneously to support the video layer. Therefore, we recommend that you use a device with a supported chipset. (This is not very relevant to CPU or GPU capabilities.)

iPhone and iPad models running KineMaster can support video layers and chroma key. (However, the support is from iPhone 5S.)

If you are using a device that is not supported, we would like to extend our sincerest apologies for the inconvenience as we are constantly working to support a wider variety of chipsets, and we will do our best to increase the list.
