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.
The .jpg filename extension refers to digital photography files or digital images that are associated with the JPEG file format specification. The joint photographic experts group, or JPEG for short, is a file format from the 'lossy image' class of image formats. Many devices including smartphones with inbuilt cameras and professional digital SLR cameras support the JPEG/Exif file format natively. Such support allow images captured on these devices to be stored directly into the jpg format without conversion. Efforts towards standardization of the JPEG format first begun in 1992 with ISO/IEC 10918-1:1994
FreeFileConvert uses tuned encoding for MTV to JPG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload MTV files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized JPG 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 JPG audio with dependable progress tracking.
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.
Being a 'lossy image' file format, digital image files saved as .jpg files use encoding algorithms that make inexact approximations of the photographic data to save on storage space during compression. This allows for relatively small files that are suited for delivery over networks or in low bandwidth scenarios. The jpg file format is flexible in that it accommodates a tradeoff between the size of the file and the image quality during compression. Image compression may leave noticeable artifacts in the produced image. The maximum resolution supported by the JPEG format is 4 Giga pixels.
