Upload M4V files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized MP3 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 MP3 audio with dependable progress tracking.
The M4V makes use of both the H.264 and MPEG-4 video codecs. It is similar to the MP4 file format and its structure is based on the QuickTime media file format. M4V files use M4V extension similar to how extensions are used in MP4 file formats. The audio encoding in M4V is also the same as MP4 files and features lossless encoding, scalable lossless coding, MP3, MP2, MP1, CELP, HVXC, TWINVQ, TTSI (Text to Speech Interface) and SAOL (Structured Audio Orchestra Language).
The MP3 format compression algorithm works through perceptual coding. A technique in which audio artifacts outside the auditory range of the average human, are reduced or 'cancelled out'. The result is a near perfect replication of the original audio sample at a compression ratio of 11 to 1 at 128 kilobits per second. Audio quality can be controlled by such factors as the bit rate, sample rate, among other features. But bits rates being the main determinant of audio quality can be adjusted between the typical range from 128 kb/s to as high as 320kb/s.
