Meler Interlacer Performance
interlacer uses only the CPU to
achieve over three times real time throughput rates for 1080p at 60 or 50 frames/sec input rates.
At this performance level, many host CPU system properties can restrict
performance, such as CPU clock rate, number of processors, system load, etc.
For 1080p60 performance levels detailed on this page as of September 2012, we recommend an
processor overclocked to 4.2GHz, and one or more Western Digital
VelociRaptor disk drives or Samsung SSD 830 drives for local video
storage or caching if needed.
Meler File I/O and Bandwidth Issues for 1080p
output to disk drives may limit throughput for 1080p, even
for reduced chrominance bandwidth
for an in-depth discussion on this subject. The
rates in the Meler
throughput table below includes using
to read pre-compressed files from an SSD drive, pipe the resulting
uncompressed output into Meler
, then pipe Meler
output through y4mzip
compression, and finally write the compressed output to a Samsung SSD 830 solid-state drive. In the table below, we give
input frames/sec figures for our suite of 1080p test sequences
. Maximum throughput rates for Meler
measurably dependent on image content, and the Meler
operating mode ('-M
') and I/O formats ('-f
' and '-F
') have only a minor impact on the throughput/thread.
