GoPro cameras can create silky smooth slow-motion sequences of bike jumping, skiing, skateboarding, water splashing, or other activities. The action cameras provide a wide range of options of slow motion frame rate, among which 1080p 120fps and 720p 240fps are commonly used settings for slow-motion videos. What's the difference? 1080p 120fps vs 720p, which one should you use? In a nutshell, 1080p at 120fps gives better image result while 720p at 240fps is slower. Scroll down to dig out more information about the comparison between 1080p at 120fps and 720p at 240fps in GoPro.
Differences between 1080p 120fps and 720p 240fps
● 720p 240fps: low resolution, small file size, suitable for phones, tablets and the web, slow motion 8x, requires more light.
● 1080p 120fps: HD sharp image, bigger file size, commonly used resolution, slow motion 4x.
Compared to GoPro slow motion 1080p 120fps setting, 720p 240fps delivers more details in a shot, making it a better choice for faster objects and ultra-slow recordings. That is to say, 720p 240fps is preferred when using GoPro to capture sports like skateboarding, skiing, biking, water moving, things splashing, and such likes. However, high frame rate requires good lightning since it makes less light hit the sensor. When you produce 720p 240fps slow motion clips with GoPro, make sure you have more light, otherwise, you might get dark and noisy looking projects. That's why 120fps is kept even there's 240fps slow motion choice.
1080p 120fps slow-motion setting in GoPro, on the other hand, will end up with slightly better quality but faster movement than using 720p at 240fps. 1080p 120fps is a sweet spot for shooting jumping, running, and other slower moment. In summary, it's hard to say 720p 240fps is better than 1080p 120fps when it comes to GoPro Hero 6/5 slow motion settings. It depends on what do you use it for.
● 1080p at 120fps: about 370MB per minute.
● 720p at 240fps: about 300MB per minute.
The file size of videos from GoPro is determined by the video length and bit rate. The higher frame rate doesn't transfer to larger file size. But resolution impacts bitrate, thus higher resolution means bigger file size (also check how to calculate your GoPro video size). You don't need to worry much about the output file size. With the help of GoPro video processing software, VideoProc, it's easy to cut GoPro video size down without noticeable quality loss.
Compare GoPro (Hero7/6/5) slow motion video 1080p 120fps vs 720p 240fps, there's no real standard use for slow motion. It depends on your final goal. 1080p offers twice the resolution of 720p. If higher quality is the most important factor to consider, then you should choose to shoot video 1080p at 120fps. 720pf 240fps is a good option if you want to create a smoother video with great effects for faster action like the golf swing, snowboarding, skiing, etc. Quality, sports action, file size, slow motion effects are main factors to consider when selecting GoPro slow motion settings. Ask yourself the following questions if you feel puzzled which GoPro slow motion settings you should use.
What resolution do you need? 1080p HD or 720p?
What is the activity you are going to capture with GoPro?
What slow-motion effect do you want to get? Slower or Faster?
How is the light condition? Is it really suitable for 240fps?
Do you care much about the final size of the GoPro slow motion footages?
Note: When shooting activity at high frame rates in warm ambient temperatures, GoPro uses more power.
