## RaceChrono Pro Reviews in Japan

### ***-- "Bug when exporting 4K video"
I recorded a 4K 60fps video with built in recording feature, and could previous it normally. But when exporting the video with data overlay, I could only get a 4K video with 16.67fps. There was no available settings for that.
-- 奕23333, 2024-11-14

### ****- "gopro 12 13の対応をお願いします。"
goproは11までしかremote controlが対応していません。12と13の対応を早急にお願い致します。
-- kenta⭐️, 2024-11-04

### *---- "サポートが全く機能していない"
メールも無視。
-- ty_chi_whip, 2024-09-16

### *---- "使い方がわからない"
スタートゴールの位置が動かず設定できません。
-- 鬼の大腿四頭筋, 2024-09-15

### **--- "No response from support(2024.7.30)"
I am Japanese and use this app in Japan. Please tell me how to set it up. On the session screen,I tried to compare the best rap with other rap. On a map,two small arrows move along the line. Despite the difference between the best rap time and the time being compared to, two small arrows end at the same time. I want to set the small arrows to move at each time. Another person seems to be able to set it up like that on iPad mini.
-- shalonica, 2024-07-30

### ***-- "複数台のカメラ接続が出来ません"
GoPro5を2つ同時に繋げようとすると競合するため1つを無効化しないといけません。
GoPro5と6とかみたく、全て別バージョンのGoProを使わないといけないのはいただけません
-- いつも配達ご苦労さまです, 2024-07-20

### ***-- "タイムの比較があまり意味ない"
タイムの差があるのにマップに表示される矢印がが同じなので、意味が無いと思います。
計測自体は問題ないので、そういう所を改善して頂けたらなと思います
-- ローリングスカイ。, 2024-03-10

### ***-- "大幅なGPSの誤差"
Qstarz BL1000GTで計測したが昨日はタイムの誤差が酷く使い物にならなかった。あとでGPSの起動を確認するとコースから大きく外れて走行したことになってしおり1周4分だったり1.10秒だったりと完全に狂っていた。
今まで使っていて初めてのこと。ベストタイムが出たと喜んでいたが恐らくアプリかGPSロガーのエラーであろう。
