Why video quality determines analysis quality
Cricket technique analysis starts before the upload. The best biomechanics model or coach cannot recover a clean knee angle, shoulder line, release point, or head position from footage where the body is half out of frame or the camera is moving. Good footage does not need a studio, a tripod, or a professional camera. It needs a stable phone, a clear angle, enough light, and a clip that captures the complete movement.
Treat the video as evidence. The goal is not to make the shot look cinematic. The goal is to make the body easy to read. If the camera angle changes from session to session, your report may show changes that are really camera changes. If the player is too far away, small technical details disappear. If the camera is too close, the feet, head, or bat path can leave the frame at the exact moment the analysis needs them.
Camera position
For batting, place the phone on or just outside the leg-stump line, around waist height, and five to ten metres back. This gives a strong view of the stride, front knee, head position, bat path, and contact shape. For pace bowling, start side-on from the batter's crease or square of the popping crease, again around waist height. For spin bowling, the same side-on view is useful, but a second clip from behind the bowler can help a coach inspect alignment.
Keep the phone level. A tilted frame can make a balanced player look like they are falling across the ball. If you use a bag, bottle, or net pole as a stand, record a two-second test clip first and check that the pitch line is horizontal.
Lighting and background
Natural light is best. Overcast light is usually better than harsh midday sun because it reduces hard shadows across the body. Avoid backlit nets where the sun or bright sky sits behind the player. In those clips the player becomes a silhouette and joint positions are harder to identify.
Choose the plainest background available. A single-colour wall, a net boundary, or an open patch behind the batter is better than a busy training group. If another player crosses behind the action, record again. The body being analysed should be the obvious subject in the frame.
Format and clip length
Use MP4 where possible. Record at 720p minimum and 30 frames per second minimum. Higher frame rates can help for fast bowling release or impact timing, but consistency matters more than chasing the highest setting. A three to eight second clip is enough for most deliveries or shots. Start recording before the movement begins and stop after the follow-through settles.
Do not upload a full net session when one delivery is the target. Long clips slow review and make it harder to compare like with like. If you want to analyse five cover drives, trim each one into a separate clip.
Common mistakes and fixes
- Blurry footage: wipe the phone lens, tap to focus on the player, and avoid digital zoom.
- Wrong angle: move back to the leg-stump line for batting or square-on for bowling.
- Partial body: check that feet, head, hands, and follow-through stay in frame.
- Moving camera: lean the phone against a fixed object or use a small tripod.
- Too much dead time: trim to the delivery, shot, or throw being analysed.
- Different angle each session: mark your camera spot with tape, a cone, or a crease reference.
A simple recording drill
Before a serious net, record three shadow movements from your chosen camera spot: one slow, one match-speed, and one with a ball. Review them on the phone. You should be able to pause the clip at setup, load or trigger, contact or release, and follow-through without losing the body. If any checkpoint is unclear, fix the camera before you start the session.
Uploading to KYNEX
Once the clip is clean, upload the single delivery or shot to KYNEX, choose the closest skill, and keep your next upload from the same angle. That consistency lets your score, movement summary, and coach feedback reflect real technical change instead of filming noise.
