WHY I USE 24 FPS (24P) 🎞 | Which frame rate should you use?

October 19, 2019


Hey and welcome you to my new video. This time I’m talking about why I use 24p in all of my videos I would say it’s a common question,
especially when you’re a beginner, what frame rate to choose and there’s
actually not a perfect answer for that. Simply because it really depends on what you’re shooting for usually. But for me I decided that 24p just works best because
of the following reasons. And the first and also the most important reason for
me is the quality that I get per frame. So here’s a simple calculation. Let’s
say I would shoot in 30p with 100mbit/s then every frame has
around 3.3 megabits per second of quality, right. So I don’t get that much
detail per frame but when I shoot in 24p I get 4.16 mbit/s. Oh there was a
little insect… But when I shoot in 24p I get one third more quality or details in my picture as if
I would shoot in 30p. So that’s the first reason here why I shoot in 24p
and that’s also the most important one. And the next big reason and also a
reason why I publish in 24p is that when I record the videos in 60p or 60
frames per second I can get a better slo-mo. So for example when I
shoot in 60p and 4K and I publish my videos in 30 frames per second, I
can slow down the video by just 50%, right? But when I publish my video in 24p
after shooting it in 60p then I can easily slow it down up to 40%. So I get
even a better slow-mo than in 30p and I mean in a lot of shots it doesn’t
really make a big difference, but sometimes you have a shot that is a
little bit too short to slow it down just to 50% and when I can slow it down
up to 40% it actually fits to the music. This doesn’t happen so much but
sometimes it’s just better, but of course there comes also a small problem with
that with shooting in 60 frames per second and this is simply that the first
point that I mentioned doesn’t count anymore. So you actually get less bitrate
per frame of course when you shoot 60p. But luckily a lot of cameras do
something against it. So for example in the GH5 records 150 mbit per second when you shoot in 60p. Of course you can also shoot in
24p with 150 megabit per second but at least I have a little bit more bitrate when
I shoot it in 60p than with a normal hundred megabit per second camera. And also the GoPro Hero6 does a good thing here so when
you record in 60 frames per second with a GoPro Hero6 then it records an HEVC. This is
a compression format that compresses the files 40% more than h.264. So that means
that you also get a bit higher quality per frame than if you would record
with the same bitrate in h.264. And the last point I want to mention
here is actually not that important anymore because we’re living in a
digital age and that means that nearly every device today is capable of playing
both NTSC and PAL format. And that would be my last point here, simply because
usually you have the NTSC in the USA and the PAL format in Europe but 24p is the international cinema format. So it can be played everywhere. I mean today
it really doesn’t count that much anymore. It wouldn’t be a decision-making
point for me but especially when you shoot for clients and they are not
hundred percent sure if they just want to publish the video on social media or
maybe also in cinema in the future as an advertising clip or something, then it’s
probably better to shoot in 24p. Because it can just be displayed perfectly on
every device in the cinema or on the internet, just like everywhere. So just
the last point, even if it’s a pretty small one, is also one point to
consider. I hope you liked this video and I was able to help you a bit with the
decision of what frame rate to choose, especially if you’re a beginner and if
you like this video then please hit the subscribe button now. It really helps my
channel to grow so that I can publish new videos like that in the future to
help you become a better filmmaker. I will go to the beach now
swimming a bit and after that it’s working time for me. I hope you have a
great day, too.

  1. Hi Pascal, what lens are you using to get that nice soft background on the GH5 and which polariser please? great videos, really enjoy looking at other parts of the world!

  2. awesome content! I always have tried to understand what frame rates do to affect the quality of the video you take, but now I know! Thank you

  3. Hi! Why do you not shoot 25fps when you are from Germany. I understand why you shoot 24fps over 30fps but why not 25fps and follow the "European industry standard"?

  4. Thanks for the video. I recently experimented with 24fps but found my footage came out choppy when using 60fps exported on a 24fps timeline. I love the look of 24fps but had to switch back to 30fps because of the choppy issue. Take a look at my first 4 Cornwall vlogs to see my point, mainly on the drone footage. Any advice appreciated, thanks again!

  5. I'm sure you answered this elsewhere, but I'm new to your channel. Do you use a LUTs pack for your B Roll?

  6. because you like the stutter and judder feeling with 24fps ,30fps it's stable without stutter.60fps it's smoothness.
    that's the main reason .

  7. You have to be a dam good drone pilot to get butter smooth vids in 24 fps. Also wind doesn't help with 24 fps. I love the look but its a challenge.

  8. People have different preference, but when you talk about the megabit, i finally understand why people record in 24fps other than cinematic reason

  9. 24fps looks so nice and cinematic ,that's why I like it,but now I guess I know the tech reasons behind it as well..thank you for your explanation.

  10. Wow, so you're a professional video guy, but rendered a 21:9 video in a 16:9 aspect ratio. From an ultrawide user's perspective: "Thank you very much!"

  11. Hi there, love your videos! Been super helpful. Recently acquired a GH5 and I was wondering what settings/recording format do you use for VLOGing and how do you go about the autofocus?

  12. I'm a beginner and I'm still figuring out what frame rates fits my filming style the most. When I record in 24 FPS my footage gets extremely choppy 🙁

  13. Would anyone in the comment thread have an opinion on 24fps v 30fps when shooting in night vision? Im new to videography so please be gentle. Lol. I do alot of night vision recording. Oh and how would i find out my bitrate? I hope thats the right term to use when referring to the mbps he was talking about…..Thanks and its nice to find a group like this that is here for sharing information especially when im new to this. Ive always wanted to get into this but I've just never been at a point in my life where I could. Now i can and I have discovered a passion i never knew i had!

  14. Oh and one more question… Can anyome recommend an affordable, user friendly video editing software for a novice such as myself? I have 2 windows tablets that both have the video editor software built in. Is the windows video editor a good software? I am about to be filming my first of many documentary style films and i would like for the final product to look professionally made and edited. I dont want cheesy fade outs or left to right slide outs…i want it to look good.

  15. Quick question what about shooting in 30 but when importing lower it to 24? Or are you still loosing that image quality at higher rate as you mentioned?

  16. 1:56 I think slowing down an originally 60 fps footage to a 24 fps slomo results a choppy video, because of inconsistent loss of frames.
    Here is the resulted distribution of frames and pair matching:
    60 fps frames: [1-loss] [2-kept] [3-loss] [4-loss] [5-kept] [6-loss] [7-kept] [8-loss] [9-loss] [10-kept] [11-loss] [12-kept] … [58-loss] [59-loss] [60-kept]
    24 fps frames: [1] [2] [3] [4] [5] … [30]
    Slowing a 60 fps to 30 fps is shows a consistent matching, therefore a smooth video result:
    60 fps frames: [1-loss] [2-kept] [3-loss] [4-kept] [5-loss] [6-kept] … [59-loss] [60-kept]
    30 fps frames: [1] [2] [3] … [30]

  17. To be honest, the main reason why people shoot 24 is for minimizing size and load on the CPU in post, with cinematic look being a close second. However, you do make a good point about the quality per frame but to be honest, most cameras today don't have discrepancies in the quality between 24 and 60fps…well, most prosumer cameras at least. Still, I shoot 24 in 4k because the fewer frames over 2 hours makes a difference. Short 4 minute YT videos though…I would say, the standard is leaning toward [email protected] except for cinema shorts. I mean, why would manufacturers put so much effort in making it a standard if people weren't evolving toward it?

  18. 24 vs 25 FPS is not so clear. We have PAL in the UK and 50hz mains lighting, so I get less beating in night lighting with 25fps than 24. But I take your point about 60fps which has a better relationship with 24 then 25fps! Thanks for some nice simple explanations

  19. I have a 29.97fps movie. When I burn it to dvd, which automatically converts it to 25fps, (I can't alter that), my movie comes out slightly jerky! What do I need to do to the movie to make the motion come out onto dvd, looking smooth, please?

  20. Hey Pascal, does 24fps apply to drones for b-roll shots? I mean mostly nature or without people in the shot. I am using the Mavic Air. Thanks!

  21. well I m in problem bro, all my travelling videos are in 24 fps by default because they all recorded through iPhone, so if I am adding some speed ramps or slow motions it's getting flicker / double image or u can say ghosting effect! it not smooth at all in slow motion at 60%

    how do I solve this?

  22. Hi there!
    I do live in Europe and i use to shoot my film in 25 fps, how can i be sure that my film come out without any issues regarding to other frame retes?

  23. Watch this short film and tell me if you like the idea of going a even lower frame rate than 24…like 1 frame for a few seconds…

  24. I don't think video compression math works that way….

    Lets say you are shooting with long-GOP, with lets say 1-iframe every 2 seconds, that will be nearly 3 to 10-times smaller in size than doing all intra-frame capture. On the GH5 for example, the all-intra capture mode is 400mbps, versus the 150mbps of its long-GOP mode. If the GOP-rate is unchanged between 24p and 30p mode, (1 key frame per 2 seconds), that lower frame rate doesn't offer 30% more bit quality, but more like 5% more bit quality. This is because most of the bitrate cost goes towards the keyframe, and both 24 and 30fps video can have the same amount of keyframes. It does depend on how the video encoder is setup, but just something to consider.

    Even if you were shooting with Intra-frames only, then the math might hold up, but even though by that logic you might as well take photographs at 8-fps. Motion is data — and by shooting at a lower frame rate you lose that additional motion data. We see this with slow-mo video — those extra frames are valuable data.

    Lastly, you can shoot raw; why limit yourself to just 100mbps even? Lots of cameras are doing 150mbps or even 400mbps. External recorders can do 4:4:4 even.
