How Can Make Motion Raspberry Camera Faster

Raspberry Pi Photographic camera boring motion

The Raspberry Pi camera has had a software turbo charge allowing video to be recorded at 90 frames per second meaning you can make slow motion videos of fast moving action.

The Raspberry Pi camera is great for creating timelapse videos and then you tin can see boring things move quickly such as clouds passing by and plants growing merely now with the latest software update you can film fast move at 90 frames per second and play information technology dorsum in slow motility at about a 3rd of the speed of the action. So at present you can create slower motion videos of wildlife equally seen in nature programmes or analyse your golf swing or only mostly break things and sentinel them shatter in to pieces.

The Raspberry Pi camera module has e'er been capable of capturing video at 90 fps simply upwardly until now the software has non been able to use this capability. The developers of the Raspistill and Raspivid camera utilities have managed to update the software to take reward of the cameras capabilities in the latest update of Raspivid v1.3, which also requires an update to the Raspberry Pi firmware.

Standard video plays at either 24, 25 or thirty frames per second depending on the format so to get video to record at 90 fps at that place is a trade off in quality equally more data has to exist saved in the same amount of fourth dimension. So the image looks a bit blocky and is limited to a resolution of 640 x 480 every bit opposed to high definition at 1920 x 1080.

How to Take Hi-speed Video

Firstly you lot will demand the latest version of Raspbian with the latest firmware.
To update your firmware open LXterminal and enter

sudo apt-get update

in one case the update is complete then enter

sudo apt-get upgrade

this will as well update Raspistill and Raspivid to the latest versions.

now ready the camera and enter the command

raspivid -h 640 -due west 480 -fps 90 -t 10000 -o video.h264

(-t = length of video. 1000 = 1 second)

this volition record 10 seconds of video at 90 frames per 2d in the raw video h264 format. This will need to be converted to MP4 format before it is usable by near video players.

Note: yous will want to capture video to a USB memory stick rather than the Raspberry Pi's SD menu. This volition usually be /media/[usbstick name here]
If you don't know the name of your retentivity stick enter the command

df -h

look for the entry under /dev/sda1 you will want the path to the right /media/usbname. This information will as well show you lot how much space you accept left on your retention stick.

so at the end of the Raspivid command enter

-o /media/usbname/video.h264

Dissimilar frame rates are available at unlike image sizes, the larger the image size the slower the video speed will be. These are the frame rates and epitome sizes available:

Modes:
2592 x1944 up to xv frames per 2d
1920 x 1080 up to xxx frames per second
1296 x 972 upwardly to 42 frames per second
1296 x 730 upward to 49 frames per second
640 10 480 up to 90 frames per second

Converting the video to MP4 for slowmotion playback

Once you have captured your video you will need to catechumen it so that it plays back in tiresome motion at 30fps or even 15fps. A program called Mp4Box will simply convert the video to the widely used MP4 format.

You will probably need to install MP4Box starting time. in LXterminal use the command

sudo apt-become install gpac

to catechumen the video saved in the current folder apply the command

MP4Box -fps 30 -add video.h264 video.mp4

yous can now sentry your video in tiresome movement.

Python PiCamera library

With the firmware update and the latest version of the PiCamera python library yous tin can also use the 90 fps video modes in your python programs with the uncomplicated command frame rate = 90

#!/usr/bin/python3
#Run the Pi Camera at 90 frames per 2nd for ten seconds

import picamera

with picamera.PiCamera() as photographic camera:
   camera.resolution = (640,480)
   photographic camera.framerate = 90
   camera.start_recording("video.h264")
   camera.wait_recording(ten) #length of video in seconds
   camera.stop_recording()

impress("Video Recording at 90FPS finished")
