Using FMLE with blackmagic design intensity pro on windows 7 professional with 720p60 input, I am unable to adjust framerate from the default input value.
I want to set framerate to 30fps but the encoded output (H.264/VP6) is always 60fps.
Using ffmpeg along with bmdcapture tool, I am able to encode 500kbps, 30fps correctly.
Following are some of the FMLE configuration settings I have tried with Intensity pro:
1. Input=1280x720, Framerate=30fps, bitrate=500kbps, output size=720x576.
Result observed on statistics screen and also verified by dumping the content: output bitrate=1Mbps, Framerate=60fps.
2. Input=1280x720, Framerate=60fps, bitrate=500kbps, output size=720x576.
Result observed on statistics screen and also verified by dumping the content: output bitrate=500kbps, Framerate=60fps.
The output framerate remains unchanged irrespective of the framerate we request from FMLE. Instead, the bitrate doubles up if we try to reduce the bitrate to half.
I see same behavior with FMLE GUI / FMLEcmd.exe.
Is it just me or it is a known issue with FMLE with Intensity pro on windows?
Any pointers on how to go about fixing the problem will be much appreciated. Thanks.
