Convert avi to otb

What is the difference between .avi and .otb?

Description: An AVI file is a file saved in a multimedia container format created by Microsoft. It stores video and audio data that may be encoded in a variety of codecs such as DivX and XviD. AVI files typically use less compression than similar formats such as .MPEG and .MOV.; The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
