Bitrate is the most important factor in determining a video file size. Technically-speaking, you can have a 4K video with a lower bitrate than a 720p video. However, in this instance, the 4k video quality would appear poor but take less space on the disk when compared to a 720p video. And if your video contains audio? That track has its own bitrate as well.
Audio: Some containers allow multiple audio tracks embedded in the video files. Hence the size of the video depends on no of tracks and bitrate of the audio as well. 192Kbps bitrate is considered good quality audio for stereo sound.
For example if I select the built-in Internet 1080p 29.97 and change the bitrates to 10,000,000 max and 6,000,000 avg the rendered output mp4 actually is encoded (as reported by MediaInfo) at a bitrate of 10.1Mbps with a maximum bitrate of 10,000 kbps.
FYI: It's not a Mediainfo problem as the file sizes verify the higher bitrate (10Mbps vs 6) with a much larger file! In my about 14 second sample the QSV encoded file is about 10.5 MB while the Mainconcept is 17.6 MB.
Does anyone else see this as a problem? I target specific bitrates for my output for different customer requirements and usage. I ask for the required bitrate in the template I'm using and I DON'T get it. It would be ok if it was off by a little (10%) but it's not even close at over 30% off!
I can make AVG and MAX the same and the output is much closer to what was requested but I feel like I'm limiting the encoder. I could also choose constant but again - limiting the encoders ability to vary the bitrate based on content.
I understand there are options but if you request a bitrate that should be a target. I don't recall having this issue with VP15. I think it was a problem with the first VP17 release but was better in a couple of the patches, just to come back worse in 421. I've used a lot of different Video Editing (pro and consumer) and they all get much closer to template requested bitrates. In addition, the Magix HEVC encoders seem to do a much better job.

Do you know what is video bitrate? This post addresses the term bitrate, explaining how bitrate affects the video quality, shows what is the best video bitrate and how to easily change video bitrate with free MiniTool software.
Video bitrate is the amount of video data transferred for a unit of time. Usually, it determines the quality as well as the size of video/audio files. You have to make sure the data transfer quickly if you want to create a great video.
CBR is an encoding method that keeps the same bitrate throughout the entire video, making it easy to playback and quick to load. CBR is useful for streaming multimedia files because the video constantly being downloaded, and is subject to stutter with bitrate spikes.
VBR allows the bitrate of an audio file to dynamically increase or decrease depending on the level of detail needed in a given moment. When compared with CBR, VBR provides significantly higher video quality with a much lower file size. If you encode audio with VBR rather than CBR, you can achieve a smaller file size. VBR only spikes its bit rate when necessary, thus it is recommended use for progressive and direct downloads (e.g. YouTube or Vimeo)
First, bitrate is the key measure of any video file size. But, using extreme high bitrate video will waste bandwidth. For instance, compared to 1000 kbps video, 2000 kbps video will consume double bandwidth.
Open Broadcaster Software is a free and open-source cross-platform streaming and recording program that allows video-makers to capture and record videos as well as live streaming. Video users can choose video bitrate according to their device's compatibilities and data affordability.
Every day, thousands of videos are streamed on Twitch. You can set the best video bitrate (450-6000kbps) for your video streamers to get a good viewer experience. Twitch limits all uploads to 6000kbps, but you had better go lower in many cases.
MiniTool MovieMaker, a free video editing software without watermark, lets you create and edit movies easily. Besides, it is a practical video bitrate converter for you. Moreover, it allows you to convert video to other formats including AVI, WMV, etc. For instance, you can convert WebM to MP4 for free.
After selecting a suitable video bitrate, please click OK to go back to the Export window. Next, give the name of this video and choose a location to store it, and click Export button again to save this video with a new video bitrate.

Videos contain a lot more bits than, say, high-res photos or regular old emails. If the bitrate is too low, your video may get compressed. That means even if your video starts out with high resolution and a high frame rate, your viewers may end up seeing a poorer image quality.
Key points to remember: a higher bitrate results in a larger file and better look for the video. Although you can still experience some challenges in the form of limited bandwidth and buffering, there are fortunately several ways to resolve the issue.
HEVC or platforms supporting ABS aim to tackle the problem with bandwidth limits, while the recommended bitrates for different video settings help avoid buffering. And you can improve your upload speed by sticking to a wired connection, using multistreaming services like Restream, turning on ad blockers, and working only with the latest programs.
To fix video not playing on iPhone problem, you can rely on VideoProc Converter, an easy-to-use but powerful toolbox engineered for 4K/HD video processing. It is able to reduce video file size, transcode video to/from iPhone and adjust video parameters, be it codec, frame rate, bitrate or aspect ratio.
Texas Instruments manufactures a line of ARM + DSP cores that perform DSP H.264 BP encoding 1080p at 30fps.[71] This permits flexibility with respect to codecs (which are implemented as highly optimized DSP code) while being more efficient than software on a generic CPU.
The range is exponential, so increasing the CRF value +6 is roughly half the bitrate while -6 is roughly twice the bitrate. General usage is to choose the highest CRF value that still provides an acceptable quality. If the output looks good, then try a higher value and if it looks bad then choose a lower value.
ProRes video recording is limited to 1080p at 30 frames per second on iPhone 14 Pro models with a 128GB storage capacity. To record ProRes video in 4K at 30 frames per second, a model with a 256GB, 512GB, or 1TB storage capacity is required.
The lack of 4K ProRes video recording support on 128GB models is likely due to the 4K videos having very large file sizes. Apple says a one-minute 10-bit ProRes video is approximately 1.7GB in 1080p and approximately 6GB in 4K.
Youtube recommends sending videos with high bitrates but after several tests I have verified that it does not change the quality beyond a certain bitrate, it is more important the quality of the source of acquisition rather than the bitrate.
From full HD 1080p to which Youtube reserves 4 mbits at 2K 1440p there is an increase in bitrate up to 9mbits, which means that YOUTUBE assigns 2K a high bitrate and therefore higher quality, when you open a video on Youtube in the standard window, with standard size, choose 1440p instead of 1080p will bring a much better viewing ! So if you want a quality HD video to send your videos on youtube at least 2K at 2560×1440 resolution, the 4K is obviously even better but is very slow both in adsl upload and on-screen display as it requires a powerful CPU and a next generation video card. 2K is the best compromise.

To do this, it has done several tests with the AreWeCompressedYet tool, where it has compared coded content with libvpx (VP9), x265 and SVT-AV1, where a result of 0.1 implies that each pixel uses 0.1 bits. A video at 1080p at 30 fps would use 6.25 Mbps following that measure.
SVT-AV1 is faster and offers higher image quality at the same bitrate than libvpx and x265. In all modes it is faster, while in quality it surpasses them in modes 5 and 4. Mode 4 offers the same objective quality with 20% less bits, being only 4% slower.
Although SVT-AV1 is still in development and it will take some time to see the codec, great advances have been made in the last two years. So much so that it already offers better quality in identical bitrates, and at a faster rate when encoding it. A one-hour video can already be encoded in a matter of a night on a current high-end gaming computer. 2b1af7f3a8
