Testing Encoding Speed vs. Quality Setting in Episode
As if Telestream's Episode wasn't already fast enough, there's a way to make you encoding jobs go even faster. Here's some information from a quick test I did on Encoding Speed vs. Quality Setting in Episode. Here's the source file that I used for encoding:
Video Format: QuickTime
Frame Size: 640 x 480
Codec: DV
FPS: 30
Audio: 44.100 kHz
16 bit Stereo
Duration: 30 seconds
I used the default H.264_Medium compression setting in Episode Pro
which uses a 2-pass VBR compression method. For the first encode with
the Encoding Speed vs. Quality setting set to 90 my video took 40
seconds to encode. On my second encode I adjusted the same compression
setting and switched the Encoding Speed vs. Quality setting to 10. The
video took 27 seconds to compress. Now when comparing the quality of
both of my output files the video encoded using a quality setting of 10
looked really good in terms of quality. Many would never notice the
difference in quality as the file still produced exceptional quality
video. This is good news for those that need to compress files fast
with Episode but don't won't to loose quality.
