Why 60p




















So if you then judge a still from a 60p or 30p shot of course when sticking to the degree rule your 30p will have more motion blur. But that's not what you are providing The other side is the bitrate. Lets say a GH5s shoots at mbs. Thas mbs over 30 frames or over There must be more compression over the 60 frames. I know it's more complicated then this but I don't want to give a lecture about compression here. And because your shutter is double you would need to up the iso.

About the recoding Do you have any particular reason for wanting to shoot everything in 60 FPS? The standard USA frame rate is Some cameras crop in or change the down-sampling mode when shooting at 60 FPS, which can degrade the image.

High frame rates generally use a higher compression ratio, for example, a camera that records 30P and 60P both at mbps, would apply 3. These Filmmaker IQ videos will offer some insight. One thing is editing. It is harder to edit and render 60p vs. This might be issue if you have older computer like me. Point taken. My camera is a Panasonic G9. Despite the audio being recorded in LPCM at 60p vs. AAC at 30p I think the bit rate difference compensates for increased frame rate.

So, in the first approximation the video quality should be the same at 30p and 60p with these conditions. Sorry, quite the opposite. I wrote in my OP "I am planning to re-encode all videos in H. I'll quote my reply I just posted in response to a similar concern.

Also, the manual states that the camera records in Long GOP format. I understand that this makes it more difficult to edit but it also means that megabits per frame do not have linear relationship with the frame rate.

In fact, for videos without much action the Mbps 60p may be of higher quality than the Mbps 30p given how H. It's not clear from the documentation. As for the standard frame rate of Is it really a standard? Who set this standard? Movies are in As I mentioned, modern TVs and monitors have 60 Hz refresh rates. Many YouTube videos are in 60 fps. I think Is there really a standard frame rate? I am not arguing with you. I am genuinely curios. As to why I want 60 fps I think you answered the best: "High frame rates allow you to perceive more detail in fast motion".

Yes, I realize this. I think it should not be a big problem for me as I have a relatively fast computer and I am not going to produce a lot of videos. I can leave the PC on doing rendering overnight and longer.

Is it true? I went to their YouTube channel and spot-watched a few videos from different times including most recent. All videos were 30p. You can right-click on the video and select "Stats for nerds". Also YouTube shows that it's 60p in settings and doesn't when it's 30p. I didn't notice a big difference vs. I actually agree with you that their videos 30p look "glassy" like old TV shows.

Maybe it has something to do with how they edit them. I wish you could tell me as I have no experience. I guess if the frame rate conversion is done by dropping frames then it will become choppy. Are there other frame conversion techniques? By blending frames maybe? I'm surprised at the number of people trying to talk you out of shooting 60 fps. Wish I had a nickle for every post I have read where someone was wishing their camera shot 4K 60 fps.

I realize the technical issues with 60p like longer rendering times and file sizes and it's OK by me and my PC My personal preference is 60p and for the reason for that I'll quote Andrew S10 from this thread "High frame rates allow you to perceive more detail in fast motion". Add to this that modern hardware have support for it. I think 24 fps will be mostly gone in 20 years. Whether you like 24 fps and noise in the movies depends on your age. If you grew up with it you'll like it.

Modern generation may be growing up with 24 fps still but looks like artificial addition of noise to the movies is gone. I read an article somewhere some time ago that some years ago producers insisted on adding noise to digitally filmed movies, not anymore. The poster after you said that they enjoyed watching the Hobbit at high fps. There are maybe a few of Blu-rays in 4k60p but I think there will be more and less in 24p.

When producers learn to spend a bit more money for rendering in 4k60p there will be more movies in that format because I don't see how 60p, when done technically correct, can be worse than 24p. Is it worth the hefty price tag?

We take a look at the Cine, the high-end model in this series.

And if a certain camera records to 60fps at a bitrate and lossy compression that doesn't preserve the individual frames at the best fidelity compared with a 30fps option that does preserve the individual frames better because of the bitrate or compression, then the claim that 60fps is better and "higher detailed" is meaningless.

Again, it is already suited to slow the motion down in an editing software and the motion looks still fluent. Just to mention 2 more popular frame rates: p and p. Both are great for better slow motion. You can slow them down 4 respective 8 times and end up at 30p normal speed. Some prosumer cameras offer nowadays p or p at p. Specialized cameras of course can go way beyond frames but cost more than 1 arm and 1 leg.

As mentioned earlier, 2 fields make up on full frame, and the term field means that either the odd- or even-numbered lines of an image frame are recorded.

For technical reasons that standard defined an effective Interlaced recording: since the processor can only record one field at a time it handles them sequentially: one field after the other. Interline twitter is an another issue which is well known from TV programs where people are wearing shirts with vertical or horizontal fine lines.

A 60i video camera recording leads to effective 30 frames per second because 2 fields are required for one full image frame. Since 60i refers to NTSC color standard the effective frame rate is actually This is just mentioned in case you have a camcorder that offers 50i recording.

Brief excursion into the Interlaced past and the digital future of broadcasting: Interlaced formats became the choice of analog broadcast in order to reduce bandwidth. Nowadays, broadcast systems switches from analog to digital. However, there are more standards, as usual. Therefore 60p is a good format for action sports.

When a 60i raw format is de-interlaced to a 30 frame per second video it depends on the quality of the de-interlacing software algorithm how great your video looks, how sharp it is. For most cases you will probably see no difference to a video that was shot in 30p native format, however, since theoretically a 30p must be better than a de-interlaced 60i format I would always go for a 30p recording mode provided that I do not intend to produce for NTSC TV formats or any output that works in an interlaced mode.

If you need to convert …then it depends on several things what the best way to go is and even different de-interlacing software makes a difference. Any conversion from a higher to lower frame rate has to throw away a certain number of frames e. There are lots of opinions out there and I can only tell what works for me best. The cinematic appeal makes sense for story-telling videos like weddings, travel documentaries, and everything that has an emotional aspect and movie aspect to it.

The cinematic effect means you experience a light blur and smooth movements. Historically the degree shutter refers to a rotary disc shutter found in motion picture cams. It works like with still images: the slower your shutter speed the more blurry they get when movement is captured.

Mostly not wanted except when you go for Long Exposure pictures. I am preferring to shoot my footage in the exact frame rate I intend to edit and output later because it delivers the best results.

However, it is tempting to shoot footage at higher rates because you can capture more details. You can still decide later what you are using the footage for. In cases where you want to shoot B-Roll and slow-motion scenes you might want to be flexible and shoot at higher frame rates. If you edit different frame rates on a given timeline you will encounter limitations. To understand what happens in detail, please refer to my article: Video Frame Rates explained — Interpreting footage and using different frame rates on the timeline.

I am importing e. Photo- and video-wise. I can only speak…. Ending up with footage that was shot at different frame rates is a real world scenario — to handle that…. The video was made for the makers of Kahlua and Absolut Vodka. How much does a 3-min video cost? A very brief insight into aspect ratios like and and others: There is a variety of cinematic aspect…. Thank you for the explanation, I have several video options on my camera that are totally Greek to me, this explains them all very clearly.

For digital output like DVD or Internet … progressive frame rates are the way to go. Interlaced had in the analog world just the purpose of reducing the bandwith for broadcasting. From here on only progressive full frames count. Depending on what you want to achieve, you choose the frame rate.
