http://labs.divx.com/node/127929 Because the marketing chosen by DivX was to create DivX Plus HD format where the container selected for this was Matroska. So, they keep it the same for HEVC contents I guess... |

I see. Thanks.
I tried out the Divx10 encoder, using the 720p HEVC profile with an H264 file I'd encoded in handbrake. Impressive reduction of size with reasonable quality but I keep getting what seems to be a juddery stuttery framerate with the output. Last edited by Slitheen; 14th May 2014 at 18:41. |

Is every other frame just a non-ref B (or P even)? That would be the most sensible way to put something like that in a single file, then you could ignore every other frame with no change to the video.

Code:
ffmpeg -i source.avi -f rawvideo -pix_fmt yuv420p pipe:1 | ./DivX265_1_5_8 -fps 15 -s 1024x768 -i - -aqo 5 -br 4000 -o dest.hevc Value is outside DivX HEVC Profile: Frame rate. Must be a value listed in the profile Edit: fps 15 is not supported. Sigh. Since this encoder outputs raw video I wonder why any limitations exist at all.

Frame rates for DivX HEVC
Quote:
Valid frame rates for DivX HEVC: 60 Hz 60000/1001 Hz 50 Hz 48 Hz 30 Hz 30000/1001 Hz 25 Hz 24 Hz 24000/1001 Hz 15 fps is an odd frame rate for content distribution so it's not supported. Is there a particular reason you prefer that framerate? |

In the future, will they be capable of being reference frames, but restricted to only their layer? Or is that pretty pointless? |

This feature is roughly equivalent to x265's --temporal-layers. The trick with fixed GOP 3 B is cool, as you automatically get 2x and 4x options. Probably a meaningful loss in efficiency, though. Perhaps if 120 fps catches on . |

Then again, your CLI encoder doesn't produce HEVC videos (so "certification" and such are not the things to really care about), it only produces raw HEVC video streams. So leave the choice to the user please. One last question: your CLI encoder doesn't have any notion of 2 passes encoding and CRF encoding which is kinda counterintuitive 'cause I really don't know what to expect from the encoding based on average bitrate.

Yes, definitely there is content from some devices at 15fps and devices should be able to play that frame rate, but it wouldn't be within the DivX HEVC profile specs. My point about content was more about content distribution, especially in the case of something like 4K where high quality on large screens is a key consideration. FWIW, we have a backlog item to allow custom frame rates for HEVC output from DivX Converter later in the year (definitely for the GUI; I need to check on if this will be available in DivXEngine.exe also). I brought this up to our PMs and they're reviewing the possibility of adding non-profile-compliant encoding like lower frame rates to the DivX265 encoder as well. |

StaxRip includes the encoder and a CLI profile.
