Would MPEG-4 provide higher-clarity images than M-JPEG would? |

MPEG-4 and M-JPEG are compression algorithms (see keywords). MPEG-4 has a higher compression ratio than M-JPEG and is more effective in reducing the transmission bandwidth and storage size.
This does not mean MPEG-4 provides clearer images than M-JPEG. The original image is the most important factor. Garbage in garbage out. For a clear image, the original image must be clear and this means a higher pixel resolution (as well as luma and chroma resolutions). We can assume that MPEG-4 and M-JPEG provide similar level of loss of details due to compression. As such, a clear original image will lose similar level of details after going through either method of compression.
