在Premiere Pro中編輯Mac屏幕錄像會導致圖像碎片


1

我正在編寫一些有關如何使用網站的教程。我正在使用內置的Apple Screen Recording在帶有視網膜屏幕的Macbook Pro上記錄屏幕。然後,我將生成的.mov文件加載到Premiere Pro中進行編輯,然後將一些音頻(單獨錄製)添加到最終版本中。

當我在Premiere Pro中編輯素材時,預覽經常會碎裂,幾秒鐘後會顯示一個完整的視圖,但是這個完整的視圖有很多幀,有時是幾秒鐘,從時間軸返回。當我一幀一幀地移動時,它將顯示一個略微碎片化的圖像,然後從許多幀後退或幾秒鐘後跳回到一幅圖像。

當我通過匹配導出選項中的序列設置導出到文件時,它產生的碎片比我在編輯時看到的碎片少,但仍然有些碎片。對於某些導出,當我打開導出的文件以快速查看並點擊播放時,它不會播放視頻,但是如果我進行了一些擦洗,它將播放,然後我可以擦回到開頭並播放。

這是移動時間線後我的Premiere Pro預覽窗口的屏幕抓圖。

這與Mac Screen錄製實用程序的原始錄製中的幀頻有關嗎?它以記錄的是什麼幀率,或者是某種動態幀率),是否可以設置Premiere Pro來處理該幀率或Mac Screen Record實用程序創建的素材?

I see 2 likely causes:

  1. I think Premiere still supports only frame rates up to 60 and your videos may be recorded with higher fps. Premiere tells you what the fps is, for example in Source Monitor, right click on Properties. Or in the Project Panel, you see the fps (you may have to scroll quite a bit or add the column if it's missing). If your material is beyond 60 fps, try converting it with any other tool, like ffmpeg.

  2. Other users recently asked similar questions (see [1], [2]), so I wonder if there is a bug in Premiere or certain graphics driver versions. If so, you could try to install a slightly older version of your graphics driver. Otherwise maybe contact Adobe support.
