Is the bitrate lowered? #135

Capture Two different files, one from half a year ago, and the low bitrate one from today. What am I missing here?

From what I can see, the left one is an mp4 which may have been merged with ffmpeg, therefore it's not impossible the video and audio were re-encoded (no clue for the video from the information in the screenshot, but the audio bit rate is different).

可能是官方减小画质，缩小游戏体积

我刚才试了一下使用这个工具的GUI版本，使用合并视频和音频选项后，比特率就会降低
