Maxedia 4
For the VBR setting some packages have no data-rate settings which means the encoding package
uses data rates depending on the Low-Medium-Best settings. Other encoding packages use a
parameter for the maximum Bit rate.
One should not go lower then 12 Mbit/sec for the Maximum (20-25Mbps is better) VBR setting, no
lower then 4Mbit/sec for the Minimum VBR setting. The higher the settings for the Maximum VBR
setting, the better quality is preserved in the image.
When Using VBR make sure to set ‘2-Pass’ ON. This way a second pass encoding is done with
better image-quality as result, but encoding time will be longer.
For CBR settings use 10Mbit/sec - 15Mbit/sec data rates for good quality encoding. Results may vary
depending on the encoded footage.
Please use high profile settings for quality conversions.
Video Stream Type:
When encoding MPEG2, one can use ‘Program’ or ‘Transport’ Video Stream. For playback on a
computer ‘Program’ Video stream is better, as there is more room for the encoding to adjust data-rate
depending on the complexity of the video frame. While Transport stream is mainly used for tape
recording which needs a constant data-stream.
Note: The Maxedia does playback original Transport streams with m2t extension, created with HDV
and ProHD camera’s without any conversion is needed before importing the files into the Maxedia
Media Manager.
Color-Space:
Maxedia supports 4:1:1, 4:2:0 and 4:2:2 8-bit formats. Depending on the chosen Codec different
color-space formats apply.
Audio:
Only use 16-bit 41KHz or 48KHz encoding for the Maxedia. 24-bit will result in no audio-playback.
