Encoding presets
The X-Agora Media Encoder offers four encoding presets.
•
SQ: Standard Quality (MPEG-4). This is the default preset, and it is the
first one you should try, because it is the optimal tradeoff between
compression quality and disk space.
•
HQ: High Quality (x264). This preset performs some compression, but
results in virtually unnoticeable quality loss.
•
XQ-S: Extra Quality Small Files (x264). This preset performs lossless
compression with relatively small files, but encoding and decoding are
longer than usual.
•
XQ-L: Extra QualityLarge Files(FFVHUFF). Thispresetperforms lossless
compression with quick encoding and decoding, but the resulting files
are larger than usual.
