视频编辑软件pitivi基本功之安装篇
台式机的系统是openSUSE-Leap-15.5-DVD-x86_64
应用程序——工具——终端,切换到root用户
ruhong@localhost:~> su -
密码:
localhost:~ # zypper search pitivi
localhost:~ # zypper install pitivi
ruhong@localhost:~> pitivi
缺少的可选依赖:
- cvtracker GStreamer element not found on the system
-> enables object tracking
缺少的可选依赖: - librosa 没有在该系统上发现
-> 启用节拍检测功能
正常安装pitivi后运行报错缺少cvtracker和librosa,尝试过都不能成功安装cvtracker,根据官网提示可以通过flatpak来安装pitivi
先卸载之前安装过的pitivi
localhost:~ # zypper remove pitivi
localhost:~ # zypper install flatpak
localhost:~ # flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
localhost:~ # flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub
参考上海交通大学软件源镜像服务https://mirrors.sjtug.sjtu.edu.cn/docs/flathub
使用flathub.org网站下载是非常缓慢的,改成使用mirror.sjtu.edu.cn/flathub就非常快速了,大约耗时15分钟左右
localhost:~ # flatpak install flathub org.pitivi.Pitivi

从画在玻璃上的图像来考虑层次更容易。几块玻璃叠在一起,每一块玻璃都是一层。如果顶部的玻璃片被完全涂掉,下面的玻璃片就看不见了。另一方面,如果你只在一块玻璃的一部分上作画,你就可以看到未上漆的部分下面是什么。
每个层(和每个片段)都有自己的透明度。为了继续玻璃上的油漆比喻,如果油漆足够薄,它就可以被看穿。从视觉上看,100%的不透明度意味着您看不到该层或片段下方的片段,50%的不透明度表示您可以部分看到它们。
要使层静音,请单击“音量”图标。该图标将被切换以显示该层已被静音。要取消层静音,请再次单击“音量”图标。
与视觉不同的是,多个声音不会相互“阻挡”。如果你在不同的层上有多个音频片段,它们的声音会混合在一起。控制这些音频片段的音量只需改变它们的相对响度。
