It is interesting to compare this with 720p, 1080p and 4K television resolutions as follows: Note the width must be an even number.įor reference, the various photo modes of the GoPro HERO4 camera are as follows: This can be edited in the batch script if you wish (change parameter -s 1332x1000 to your desired resolution) but keep it in the same ratio of 1.33, otherwise the footage will look squashed or stretched. The video resolution is downsampled to 1332x1000 pixels to keep file size down and performance snappy (especially for quick initial viewing) but maintaining the width/height ratio of 1.33. This is the perfect companion to our GoPro Autodownload ‘Grab’ software (coming soon!). So we have created some simple batch files / scripts for use in a Windows environment and a Mac environment. It can also be used to quickly pull together time lapse movies without having to import it into another piece of software.Īs with many powerful tools, ffmpeg can be quite complicated due to the myriad of options.

This lets you quickly check the alignment of your rig.

To make life simpler for our clients, we explain in this article how to use a simple script and the powerful ffmpeg tool to quickly create a time slice video from a series of stills in a Bullet time rig. We have clients who run 30 camera bullet time slice rigs! GoPros are great for creating time slice footage as they have high image quality for the price, which is important, as normally quite a few cameras are required. This is also known as a Time Slice effect. This is most often used by our clients in the creation of ‘Bullet time’, the effect made famous by the Matrix series of movies. The CamDo Solutions Bullet is a great piece of kit, allowing simultaneous activation of multiple GoPro cameras.
