The VDIR app provides instant video feedback by displaying a delayed replay of actions, allowing athletes and coaches to analyze and improve performance without needing to press record.
Yes, the Video Delay Instant Replay app is available on the App Store for iOS devices and Google Play for Android devices. However, iOS and Android apps have different features. Most of the features described on this website apply to the iOS version of the app. For details on the Android app feature list, please check out the description on Google Play.
You can record your training sessions using the video delay app. Recording in DELAY mode starts when you hit the record button and captures one video file. Recording in SLO-MO mode* captures each slow-motion replay as a separate video. Videos are saved to your device’s Photos or Documents folder. You can select where to save the recordings in the app settings.
*Works only on iOS devices
You can connect your device to an external monitor or TV to provide more precise feedback during training sessions. This benefits coaches who want to display instant replay to multiple athletes simultaneously or when working out in a larger sports facility. To share the screen on iOS devices, use AirPlay or HDMI cable.
You can connect two iOS devices with the installed VDIR app. One device, let’s say an iPhone, can work as a camera capturing your actions. The other, let’s say an iPad, can receive the camera feed and work as a remote control for the app.
Note: Currently, the Remote feature is available only in DELAY mode.
The app’s Replay View, available on iOS devices, allows for accurate movement analysis. You can watch your actions in slow motion or frame-by-frame and measure angles to check your technique. You can also precisely select a crucial part of your actions using A & B markers and save it for further assessment.
Motion Detector works only with DELAY mode. First, enable the Grid button and select the number of rows and columns in the app’s settings. Grid lines detect movement in the video—you can use them as reference points for the ball or your pose. Each time your hand or the ball aligns with the detector, the line turns red. You can position the lines and adjust their sensitivity by entering the edit mode.
The app is versatile and can be used by individual athletes or sports teams for various activities, like golf, tennis, swimming, baseball, volleyball, and hockey. It’s recommended for assessment when working out alone and for training sessions with a coach, including weightlifting, martial arts, pilates, yoga, and physiotherapy. Coaches can also utilize it to analyze team drills in sports like soccer, basketball, cricket, and water polo. Gyms and sports facilities for gymnastics training or dance practice can also benefit from a video delay system.
No. When using the app for delayed video feedback without recording, the camera frames are temporarily stored in the device’s RAM and continuously refreshed. The buffer memory is cleared every time you exit the app.
