.wbmp refers to the wireless application protocol bitmap monochrome graphics file format. The format was initially developed by the WAP forum which later become part of the open mobile alliance. WBMP files are optimized for mobile devices prior to the advent of smartphones and is categorized as a raster image file format. Mobile network services such as SMS and MMS on GSM carriers typically have compatible support for this format, allowing users to send graphics saved in this format.
The .mtv filename extension is the second filename extension that refers to the proprietary video file format container AMV. AMV is a video container modified from the AVI video format and is primarily associated with video enabled Chinese portable MP4 players. Video stream files with either the .amv or .mtv filename extension can be played back on these devices. To maintain a relatively low cost, these MP4/MTV players rely on this video format and inexpensive hardware rather than more common but expensive proprietary video playback formats.
FreeFileConvert uses tuned encoding for WBMP to MTV conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload WBMP files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized MTV results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent MTV audio with dependable progress tracking.
The wbmp file format only supports a color palette of black and white which aids in keeping file sizes at the minimum possible. Binary integers are used to differentiate pixels of opposing colors. The file structure consists of several fields including the type field which represent the type of image, a fixed header of 1 byte in size, a width and height field to define the pixel resolution of the file, and finally the data field which holds the image data.
The MTV format consists of a 512 byte header block. This is followed by audio and image blocks in an alternating sequence. Each image block in the format represents an entire image frame. During playback, audio frames are parsed through an MP3 decoder whilst the video stream is decoded as complete still images. Image frame data is not compressed and as such utilizes the bulk of the available memory storage on the device. The mtv format is inherently a low image resolution / low frame rate format with a maximum 16 bit uncompressed color depth.
