Capturing a highlight and analyzing it are two different jobs, and no single app does both well. The workflow that works is two apps from the same developer: Video Buffer Action Camera catches the moment with its rolling buffer, and Coach Video Analysis, its companion app by Borama, turns that clip into feedback with side-by-side comparison, drawings, angle measurement, kinogram and chronogram exports, and presentation on a TV.
Two apps, two jobs
Video Buffer is a capture tool. It watches the game so you do not have to film all of it, and saves the seconds before your tap. It does not play back, trim, or annotate anything, on purpose. Analysis needs a different kind of tool: one built around scrubbing, comparing, and drawing. That tool is Coach Video Analysis, from the same developer. The handoff between them is just a video file, so the pair works without any account or platform in between.
Capture with analysis in mind
Analysis is only as good as the footage, so a few Video Buffer settings pay off later:
- Buffer length. Match it to the play. A single swing needs 10 seconds; a full attack sequence needs 30 or more. A little extra lead-in helps when you later want the setup, not just the contact.
- Frame rate. For technique work, capture at 240 fps (available at up to 720p on supported back cameras). Fast movement like a bat swing or a sprint stride only reveals its mechanics in slow motion. When detail matters more than speed, use 4K at 60 fps instead.
- Stabilization. Turn on video stabilization in the camera settings. A steady clip is far easier to compare against another clip.
- Save to iCloud Drive. Pick iCloud Drive as the save destination and the clip you capture on a phone at the field opens minutes later on the iPad you analyze with.
Compare two clips side by side
The core move in Coach Video Analysis is putting two videos on one screen: this week against last month, your athlete against a model swing, left angle against right angle. The Layout button arranges them side by side, stacked, or overlaid. Then the Lock button links the two videos into one shared timeline, so scrubbing moves both in sync and the moment of contact lines up frame for frame. Playback speeds run from 1/16x up to 4x, with frame-by-frame stepping for the exact instant.
Draw on it, measure it
The Markup button opens the drawing tools: lines, freehand sketches, and a three-point angle tool that shows degrees and stays adjustable, so "your elbow drops" becomes a number the athlete can see. When you compare two videos, your strokes can mirror onto the other video as you draw, which makes differences in posture jump out.
Kinogram and chronogram: the whole movement in one image
Sometimes the best feedback is not a video but a single picture of the phases of a movement. Coach Video Analysis exports two kinds:
- A Kinogram is curated. You scrub and hand-pick the exact frames that matter, the load, the launch, the contact, the follow-through, and the app arranges them into one strip image.
- A Chronogram is automatic. The app samples 5 to 40 evenly spaced frames across the clip and lays them into one strip, an instant overview of the whole motion.
Both export as a single photo you can text to a parent or pin in the locker room. The kinogram guide covers how coaches build them, including the five positions sprint coaches read.
Many highlights from one long recording
If you did film a longer stretch of the game, the Clip button (Quick Save) pulls short highlights out of it fast: it builds a small window around the playhead and saves just that moment, with or without your drawings. Scrub to the next play, tap Clip again. One long recording becomes a dozen shareable moments without re-exporting the file each time.
Put the analysis on the TV
For team talks, Coach Video Analysis presents to an external screen over AirPlay or an HDMI adapter. The TV shows a clean view of both videos and your drawings, with the controls staying on your device. The whole bench sees the comparison while you drive it from the iPad.
Get the pair
Capture with Video Buffer Action Camera: a rolling buffer of 2 to 100 seconds, 4K, 240 fps slow motion, and saving to iCloud Drive. Analyze with Coach Video Analysis: synced side-by-side comparison, Markup drawings and angles, Kinogram and Chronogram exports, Clip quick saves, and AirPlay or HDMI presentation. Same developer, and the only handoff is a video file.
