The Picture Exchange file format, shortened PCX, with the .pcx filename extension is an image file format developed by ZSoft Corporation. It was initially released in 1985 as a lossless bitmap image format and for a time was the default file format for PC paintbrush. The format is now largely superseded by other formats given the target platforms for the software associated with the format are no longer in production, i.e. MS DOS and Windows 1.0.
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 PCX to MTV conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PCX 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.
Later iterations of the format supported 24bit color palette, upgrading from the original 2 to 4 colors. Byte ordering used by the format is little endian ordering with three blocks; a 128 byte header, image data and an optional 256 color palette. Image data is stored in an orthoganal arrangement of scan lines ordered from the top to the bottom. Files can eiher be compressed using the simple RLE (Run Length Encoding) algorithm or uncompressed.
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.
