Hello,

I often wonder if setting high bitrate in rendering output is really worth it.

A few years ago I was filming a drone video for one of the biggest television in Poland. I had asked them to share with me the whole film when they edited it where drones shots were only a singles shots, because there were many interviews etc. They did it and I was shocked and I wondered why the video they edited and they rendered is not so much size, but the quality of the video was very impressive. Does it mean that tv encoder they used is much efficient than the encoder we use it in not television tools/not television softwares?

I have used to use HEVC (GPU encoding) setting in Voukoder settings for a few years till now. The files I have been rendering were rather always big than small ones. That's because the bitrate I set up was even 50-60 Mbps, because I always wants to have the best quality possible.

Today I applied such settings in Voukoder (version 12.1):

- HEVC (Intel QSV)

- Strategy: Intelligent Constant Quality (w. lookahead)

- Quality: 24

- Preset: Very fast

- Profile: None

- Audio: AAC (ffmpeg) - 512 kbit/s

- Output: mp4

The output video file was extremely low size, but the quality was not so bad. My 9 minutes output video had 0.5 GB file size (of course 4K 25p resolution HEVC). I don`t see any bad pixels/artefacts which would let me think not to set up these settings for my future renderings.

My PC:

- 12th Gen Intel(R) Core(TM) i9-12900KS   3.40 GHz

- DDR5 128 GB RAM

- Nvidia RTX 2080TI

My questions:

1) Can you share with me the Voukoder settings you use to get the best quality possible if your input videos have 200 Mbps bitrate and you don`t want to get such big file sizes?

2) Can you tell me what maximum bitrate you set up in Voukouder and what Quality settings you set up to get the best quality possible and not to have such big file sizes?
3) What is in your opinion, the maximum bitrate boundry / quality settings boundry where you don`t see any better quality videos if you cross this boundry setting?

4) What settings for my PC set up you recommend me to set up in Voukoder to get the best quality where I use most often 200 Mbps bitrate input videos?

5) Do you recommend me to set up HEVC GPU encoding in Voukoder or HEVC (Intel QSV) encding in Voukoder? When I render in both of these settings I see that CPU is not used so efficient. I see that it is used in 40%. Can you write to me if there any possible way to use CPU much efficient than it is now on my PC?

Thank you in advance for help
