If you choose Constant Framerate, VidCoder will apply that filter to the encode and you should see this in the log:
If you see that, but it's still variable frame rate output, that means the issue is in the HandBrake engine. |

This is a little awkward, because everything was set as necessary (constant framerate) and still variable framerate is shown in Mediainfo.
According to Mediainfo, a rendered video is encoded in Variable framerate, even though Constant framerate is set in preset.
Source is MKV with NVEnc HEVC CQ0, six audio streams (3 DTS and 3 AAC), 5 subtitles (SSA). The source file is made by VidCoder.
Source file MediaInfo:
Frame rate mode : Constant
Frame rate : 23.976 (24000/1001) FPS
Color space : YUV
Destination is:
VidCoder has to encode just the video with the fitting bitrate and combine all the streams into a MP4.
Everything is in the new file, but the video is now in Variable framerate and it should be in Constant framerate.
Encoded whole video MediaInfo:
Frame rate mode : Variable
Frame rate : 23.976 (24000/1001) FPS
Minimum frame rate : 15.947 FPS
Maximum frame rate : 23.976 FPS
Note: If just the first chapter is being encoded, from the same video, the framerate shows as Constant framerate. The video has 18 chapters.
Encoded 1 Chapter MediaInfo:
Frame rate mode : Constant
Frame rate : 23.976 (24000/1001) FPS
Color space : YUV
When encoding the first 9 chapters the resulting framerate is Variable!
When encoding the first 4 chapters the resulting framerate is Variable!
When encoding the first 3 chapters the resulting framerate is Variable!
When encoding the first 2 chapters the resulting framerate is Variable!
Could you pleae tell me how to get the whole video encoded in constant framerate?
I know that you cannot test with the same source file, but I can repeat this issue with other files that VidCoder/Handbrake encoded with source files in NVEnc HEVC, because this is the main codec i use with my collection. Could this be caused, because of reencoding HEVC? But if, why?
