Hello!
I am new here and I started to use Voukoder recently.
I am exporting 4K UHD footage from a source video XAVC-S 25fps@ 80-100mbs VBR, from a Sony Camera (shot on tripod).
I am also exporting 4k UHD footage from a source video H264 25fps@ 100mbs, from Mavir Air drone
I created an export profile using Voukoder codec (please check images in attachemt).
Encoder: HEVC (NVIDEA NVENC)
OPTIONS:
GPU: GeForce GTX 1070
Compute Capability 6.1
Bit depth: 10 bit
Preset: Blu-Ray
Profile: Main
Tier: High
Strategy: Constant Quantizer (QP)
Quantizer: 15
Everything went well but the exported files have huge diferences in datarate.
The drone footage has 125Mb/s bitrate while the Tripod Footage from the Sony camera has only 19.8 Mb/s
This is quite a diference in bitrate taking into consideration that I am using the same profile / export settings. The only diference is that the drone footage has no audio. The Sony / tripod footage has audio.
Can someone explain me why is such a diference in the bitrate of the exported footage?
19.8Mb/s seams to be very low datarate for a 4k UHD video file. The video looks good but I am afraid that the datarate is not good/high enough for delivering this to a client.
Thank you in advance.
