HI I want to know how many FPS I should use for a video for the internet. I guess it depends on where I am going to show it? youtube, vimeo, etc?. if you can, please, give me a list of possibilities, thanks!
If your source footage is interlaced, deinterlace it. If your progressive frame rate is a constant 23.976, 24, 25, 29.97, or 30 fps, then keep the frame rate as it is, unless you require a very low bitrate and want to halve the frame rate. These are all widely supported frame rates, although other arbitrary frame rates below 30 fps will often work as well. Many popular devices only claim to support up to 30 fps. If your source footage has a higher frame rate or you have a variable frame rate, consider converting it to one of these constant frame rates for wider compatibility. Don't bother if you are submitting to YouTube as they will accept a wide range of frame rates and will re-encode the video for you at various quality levels.
If you are shooting all new footage specifically for the Internet, which will not be combined with existing footage, and you have your choice of frame rate, 30 fps (progressive) is a good and popular choice. If you will not have any fast motion and want that cinematic look, you may prefer 24 fps.
Most modern codecs will support whatever frame rate you throw at them. The choice is more of an artistic decision than a technical one. For the best quality, you should match the frame rate of your source or some even multiple there of. If you can choose on your source, then choose according to the feel you want. 24(23.976) is more "cinematic" and is what is used in theater films while 30 (29.97) is a little smoother and is what is used by NTSC television (like the US). 48 and 60 are much smoother but also less common. 25 is common in PAL countries.
