Video Transcoding v0.16.0 Release Notes
-
Friday, January 20, 2017
- Add a
--cvbr
option totranscode-video
. This is essentially the same as the experimental option of the same name which was removed on February 25, 2016, but now it doesn't have a bitrate argument. It enables a simple constrained variable bitrate (CVBR) ratecontrol system, less constrained than the default, producing a more predictable output size while avoidingVBV underflow
warnings. Use it with--target big
for the best results. - 0️⃣ Modify the
--abr
option intranscode-video
to no longer use a bitrate argument. Instead, it relies on the--target
option to control bitrate, just like the default ratecontrol system and the new--cvbr
option. So, passing a bitrate argument is now an error. But you should consider using--cvbr
instead of--abr
anyway since the former is almost always higher quality. - ✂ Remove the deprecated
--no-constrain
option fromdetect-crop
and the--no-constrain-crop
option fromtranscode-video
. - Modify
convert-video
to allow HEVC format video along with H.264. - ⚡️ Update the "README" document to:
- Revise and simplify the Windows installation instructions to point users at the fine work by @samhutchins and @JMoVS on documenting their two methods. Via #115.
- Revise the "Using
transcode-video
" section to correct out-of-date performance data about the--quick
option. - Revise the H.265 answer in the "FAQ" section with up-to-date information about the x265 video encoder. Via #118.
