Hands down the best practical explanation of bit rate and how it affects the video creation process. Thank you, that cleared up so many issues I've been confused about!
Great explanation! I have a question for years now. If my camera has a max bit rate of 100 Mb/s, and I use a Micro SD card of a max write speed 60 Mb/s, I realized it still works, but what is really happening there? Am I loosing quality? Any answer is greatly appreciated.
Great video, could you do a follow-up featuring and discussing the various slr video camera bit rates 25 Mbs vs 150 or 400 Mbs and a scale for determining quality relative to file size etc. 8 bit vs 10 bit vs 12 bit.
Regarding the comments about Audio around 6:16... If your audio content consists mostly of speech (human voice) you can lower the audio bitrate significantly (32kbps-64kbps). More complex signals like Music or environments that are very noisy (crowd of people, forest at night, etc.) will require a slightly higher bitrate to avoid any artifacts, like 128+. Perceptually this approach will make a difference to the audience of the video. But, it is true that a relatively small amount file size will be saved by lowering the audio bitrate.
So, If I know my target audience is going to look my videos with a slow internet connection of an average of 2Mb internet connection It would be a smart choice to have a bitrate of 2k-3k in terms of cost-efficiency?. I loved your explanation, great video
I am trying to understand why the "Frame rate" says 29.970029 instead of 29. Does .970029 start at .000000 and go up to .999999 before creating the next frame example "30.000000 ?
So is the bit rate something Youd choose during export?? Im not comprehending where to choose the bit rate?? On the camera? Editing software? Im new with this, someone help lol Thank you in advance for a response from anyone.
Both in camera and in the software. However, what bit-rate you shoot in is key. Some cameras don't offer different options. When it comes to doing it in software, you would do it to compress the video even more. It will be found on your export settings. some offer a VBR or variable bit rate, that just shoots for a target. or a CBR or constant bit-rate, where the bit-rate stays constant frame by frame.
maybe? Being able to see the difference might be more inline with what the subject matter is than the quality or resolution of your monitor. ie. a skier going quickly past tree's would be subject matter where the bit-rate would be easy to identify, the lower the bit-rate, the more tearing you would see in the trees.
@@videomaker I watched all Fast and Furious movies which has action and movement everywhere in above 10.000 kb/s, but i watched last movie in 2500 kb/s and i didnt feel any difference or tearing in my setup.
Great video! The lumix gh3 25p & 50p shoot at 50mpbs but files size is the same, does this mean the 25p will have a better image coz it use more data each frame? anyones can help me here thanks.
i've downloaded some 4k sample video on youtube according to media classic info the overall bit rate of those video is 17.4 mb/s and 25 mb/s. i play those video on media player classic and vlc, the result is overall video is stuttering and freeze also the sound but when i play with windows media player and Movies&TV (default apps from windows 10) the video run just fine, there a bit stutter on the 25mb/s file but the overall is acceptable. i have no idea whats wrong. SPEC are : - i7 4720HQ, GTX 970M, 16GB RAM, 4K Native screen, and 1TB HSGT 7200rpm
Fab tutorial, many thanks. I've exported a 40 second promo video for a company that are going to be sending it off to advertising channels etc. I exported in a very high bitrate, do you think this was a good thing, the file itself plays fine on my PC so I'm presuming an advertising company should be ok to work with a video with a high bit-rate?
I have 2 video file one is downloaded from drive download button and another one is from idm. google drive file has 37.2mb, 1366*768 , bitrate 144kbps. And another file has 91.8mb, 1280*720, bitrate 359kbps So which should I choose?? (Both r Google meet screen recorded video)
Great video. The only question I have is how do you choose the amount of bitrates you are using when shooting your actual video? Does it just depend what setting you use? Or can you only choose the bitrate during the rendering process using your film editing software?. I hope that makes sense
Generally a camera / camcorder has its own standard bitrate, something the user can't modify. And even if editing softwares allow to choose between a large variety of video formats and codecs, having different bitrates, that won't raise the overall video quality because it doesn't match the source quality. If you shot a video at 30Mbps and the export it at 50Mbps you'll just end up by making the file size larger while not making it better-looking. So the exporting bitrate should always match the source bitrate.
The point you made about RU-vid's policy of keeping the original upload and applying any upgrades to their techniques to that original, was what I needed confirmed. I had read advice from a RU-vid tech staffer to encode at the maximum bitrate you can suffer and that your Internet connection copes with. His reasoning was, it future-proofs your video so they can upgrade quality over the years. They also recommended applying a video noise filter to all videos for RU-vid. Sadly I cannot find a denoise filter option in the encoding process in Adobe Premiere Pro. I can run it through Handbrake afterwards and apply a NLmeans Denoise filter, but that then encodes the video a second time. Do you know of a way to apply a denoise filter in Premiere Pro?
What I get is pixelation. I'm a motovlogger. I ride a dual sport motorcycle and video my rides. Rides are often on narrow trails with trees and brush close on both sides. Because I am riding at some speed, the trees and bush on each side become pixelated, as does the ground in front of the bike. I see many youTube channels of similar content though that do not exhibit these faults. So I am thinking it is perhaps camera related. Over the course of 3 years, I have tried countless encoding variations without the clear video I see on many RU-vid channels. My camera is the Drift HD Ghost. I shoot at the maximum camera bit rate at 1080p @ 30fps (the max fps on this camera). I encode at a very high VBR using the H.264 codec. Any suggestions that would help me upgrade the quality of my videos? I surely would appreciate your advice.
Hi, what about the correlation between FPS and Bit Rate to file size? I can't explain to my self: why the same video encoded at same bit rate and the same resolution, but once at 50fps and once at 25fps gives two files with almost the same file size?! Or it's hits the picture quality at higher FPS, IF the bit rate is too low?
I've also noticed that the high bitrate affects the editing power of the computer. What component should I upgrade to get a better editing at high bitrate, would the RAM be enough ?
So my question is, which would net a higher quality result? 1) 4k @ 30fps - 100 mbps 2) 1080p @ 60fps - 50 mbps Not sure if the 4k resolution with lower fps but higher bit rate is yields better quality than a lower resolution with a higher fps but lower bit rate? Help clarify please.
What should a bit rate be for a single remote 4g PTZ camera be ? Im trying to find the optimal range of settings where data wont be a problem. Trying to install a ptz camera to monitor thieves on farm where there is no wifi. The camera is solar 4g ptz single camera. Any thoughts?
the typical rule of thumb we would recommend would be for the best image. that advice would be the highest bit rate that the speed of your infrastructure can handle. However, if you are just wanting it for surveillance, then it would be to set it at the lowest rate that will still show the details you need to see. Hope this helps.
Could you please tell me how to get a better audio in background as yours, how many dbs you put to audiobackground and how many to the main audio (your voice)? thanks...
We like to put a nicely controlled Voice over (limited and compressed) at between -3db and -6db. for placing a music bed under we are typically put it at around -28db to -31db. The music is normally mastered and doesn't have a dynamic range more than 6-9db. Hope this helps. These are not hard and fast rules. They are where we start, then use our ears to make subtle adjustments. Thank you for watching!
What setting can I change to improve the fps in my recordings? My fps while im playing is perfect, but when I check the recording it's down to 5-10. I use OBS, btw.
90Mbps is the Bit rate, 8 and 10-bit are the bit depth. Watch this video to learn about bit depth ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6yXYxp0UiVg.html
Hey, amazing video, but I have a question: if I'm editing a 1920x1080 60p video tutorial based on a linux terminal, recorded at 20 Mbps, is it better to export it using 15-20Mbps variable bitrate o 15Mbps constant bitrate? Because I tried exporting it in both the scenarios, and the variable bitrate video at the end was exported at only 3 Mbps which is extremely low by the standards recommended by RU-vid. Any suggestions?
Thanks for making this video. I've always wondered how all of this worked. My question is, is there a parameter to know what's the perfect bitrate based on a given resolution? Like what's the best bitrate for 1080p video? What's the limitation over which none would be noticing a difference in video quality? Is it better to have a 100Mbps 1080p video or 50Mbps 4K video? One example is the 4K content Netflix delivers, which is said to be encoded at 15.6 Mbps vs the upcoming UHD BluRays which will have an 80 - 105 Mbps bitrate on average. It's no brainer that the UHD quality for 4K content will be higher, mainly thanks to the way higher bitrate and overall lower compression. So ultimately, does the bitrate count as much as or more than resolution for video quality? Thanks :)
+Vylkeer If you're using the x264 or x265 encoder to encode your video into H.264 or H.265 respectively, you can use the CRF (Constant Rate Factor) mode, which uses a logarithmic scale from 0 (being lossless [best quality]) to 51 (being the worst quality) to determine the desired quality, and will automatically use the correct bitrate required to achieve it. I don't think the video encoders used by professional video editors like Premiere use x264/5 so you might not have the option to use CRF.
+Vylkeer 100 mbps 1080p is alot better than a 50 mbps 4K. The higher the mbps the better it is, up untill a max point where its RAW or lose-less format (no compression).
I need help, I want to videos at 480p and 30fps (I record highlights on pc so I can put it on my phone, but still keep backup on pc, and I don't want the file to be bigger than required so it doesn't take much space on my pc) What bit rate do I choose?
If you want quality and you don't want some size of file like 700mb or 4.6 gb . Don't use bitrate based settings of codecs like ABR or CBR. Use CRF encoding - type of VBR. It works like "i want quality, so set bitate as much as need at right moment". 18 - best quality. Almost nobody could see the difference from original. 21 - lose some quality. But normally file size much small >21 - easy to see lower quality.
Dnv Goodwin oh god, I wish I understood all of the stuff you just said. Anyway, I record game highlights with Nvidia Shadowplay, I tried 10Mb bitrate(which was the smallest option and leaves the smallest size) , and it turned out fine. So I really don't understand what bitrate is still all about :(
>>Anyway, I record game highlights with Nvidia Shadowplay, I tried 10Mb bitrate(which was the smallest option and leaves the smallest size) Meh. It looks like there are not many settings in Nvidia Shadowplay, so just try you settings. If it's OK for you, use it. >>So I really don't understand what bitrate is still all about :( Bitrate - how many 1 second of you video will take disc space. Large bitrtate- better quality. It like how much water in 1 second goes from a tap. First thing you need to understand that many motion needs more file size and , less motion needs less file size.Normally in video we have some almost "no motion" scense (like game menu ) and "many motion" scense, where we need more bitrate. Of course we can just set high constant bitrate(20 mbps/s for 720p 60fps) and have a nice quality. But in this way we use even to many bitrate for "no-motion" scenes. That's why better way is to use variable bitrate . So in slow motion scenes it will be low and in "many motion scense" it will be high. So average bitrate(and file size) may be much smaller and quality higher.
Dnv Goodwin ok thanks. I mean, if I set to record at "In-Game" resolution then I can set bitrate over hundred. But when I set at 480p, I can go from 10Mb to 50Mb. Yeah, unfortunately this thing has no VBR, And what you said, you were right, when I did fast movements ingame, it _seemed_ like there was frame-drops (I was recording CSGO). So I'm gonna have to expiriment to find out the minimum I can use for in-game 90°-180° fast turns to still look nice lol. Thanks again.
Hi! I run a video prod team at a church. I've been in the video/pc area since I was 13... (I'm now 20) but anyhow, check this out. I'm recoding 720p @ 30 Fps, using .Mov/H264 (at high, not baseline nor Main) with a Average bit rate of 20mb per second. I end up recording usually an hour worth of video and I end up with 30gbs of video. Luckily RU-vid does allow those huge files to be uploaded. Do you think I'm doing it right ? I wish I could record at 1080p but the cpu starts stuttering and I can't afford that while doing a live broadcast as well as recording to my HDD. I heard Motion JPEG is a better encoder than H264. What encoder would you recommend? I'd love to have crispier videos!
Such a good tutorial/guide! However I'm wondering something: A friend of mine told me about a certain way to make a CS 1.6 video some years ago. So I made a tutorial of it. I recently found it and wanted to give it a try now that my pc is a lot better than back then. The only problem I'm facing is that he adviced me to use 7 mb bitrate in an .avi render in vegas (After rendering as uncompressed with Virtualdub) When I choose to render as .avi I don't see an option for bitrate ? It's been a really long time since I did this, so I might be forgetting something or not understanding something here. Can you or anyone else tell me why I can't or how I can choose bitrate with .avi ?
if you don't have a limit to the amount of data you can store, shoot at the highest bit-rate you can. This will give you the most flexibility in post production. Not all production will benifit from a higher bit-rate, but it will not suffer if you shoot at a higher bit-rate than is necessary.
Anyone with a good (freeware) solution for syncing video and audio of high resolution mp4 file (the file's size is 1.8GB). I've done some preliminary research and taken at least one and a half stabs at fixing the problem using Handbrake and Movie Maker, but with no success; the technical details of how to go about resolving the problem have yet to sink in. As far as I have been able to determine, so far, is that the likely reason the video and audio is out of sync is because the video uses a variable bit rate. Okay, well whatever. Now, what can I do (hopefully a tool that's free) to fix the problem. The only thing worse than a poor resolution video, is a video out of sync with the audio. Aargh! Any suggestions are appreciated. Any suggestions with detailed instructions are deeply and forevermore appreciated!
the a6000 shoots a max of 50 Mbps. you should render at minimum equal to the original source. Unless you have some delivery requirements, in that case, follow them.
yeah. However if you know how you will present the video, what that presentation platform desires, would be best practice. ie RU-vid suggested render settings.
I have a question the My XF300 records at 1920x1080 60i 50MBPS and my AG-AC160A records at 1920x180 60p 28MBPS. According to your video the lower bit rate will loose some quality. Buti like to use slow mo and at 60i (XF300) it causes a "ghosting" effect when slowed while the 60p (AC160A) has no problem at all. Its a question of quality vs functionality i guess and i am having a hard time deciding whats more important to me.
+BallzBallz Can you notice the difference between 50MBPS and 28MBPS? Sometimes it's hard to see with the naked eye. If you can't see the difference, go for the lower bitrate version that works better in slomo. :)
Wait a sec i had minecraft fps can run to 100fps and it was lagging like crazy and i dropped it to 60fps and it stopped is it cause the pc isnt good enough too handle? Or the ram is low on memory?
+dank kouros 60 and 100fps is good. It's hard for me to tell the difference between 60 and 100 because on that certain game I just can see the smoothness.
