Ever since Rebecca explained自從麗貝卡解釋 how to create a screencast in OS X如何建立一個screencast在OS X的 , I’ve been messing with Snapz X Pro. ,我一直在食堂與Snapz X專業版。 The only real problem I have with it is that the resulting files (.mov) are huge.唯一真正的問題我已經與它是由此產生的文件( 。傳送)是巨大的。 There are a few compression/save as options and I will review them, but I’ve found it much easier to take the resulting files and convert them using ffmpegX, a free audio/video conversion tool.有幾個壓縮/保存為選擇,我會檢討,但我發現更容易採取由此產生的文件並將其轉換使用ffmpegX ,自由的音頻/視頻轉換工具。 This tutorial will take you through the steps to convert .mov files to Flash.本教程將採取的步驟操作轉換。傳送文件到閃存。
- If you don’t have it installed already,如果您沒有已安裝, download and install ffmpegX下載並安裝ffmpegX . 。
- Open Snapz X Pro and select Preferences .打開Snapz X Pro和選擇偏好 。 Click the Settings button in the Include Video Track section.點擊設置按鈕, 包括視頻跟踪一節。
- You’ll notice a number of output formats - but none of them are Flash.您會發現一些輸出格式-但沒有人有閃光。 You can use H.264 for better compression (better than .mov) - but the resulting file can still be too large for web streaming (especially for folks not using a very fast broadband connection).您可以使用的H.264更好的壓縮(優於。傳送) -但由此產生的文件仍然可以過於龐大的網絡流媒體(尤其是人使用的不是非常快寬帶連接) 。 Leaving Animation as the default will result in a large file, but that file can be heavily compressed (the point of this tutorial) without much loss in quality.離開動畫作為默認將產生一個大的文件,但文件可以大量壓縮(點此教程)沒有太大的損失質量。
- Return to the Preferences screen, and this time click the Settings button in the Include Microphone Track section. Note: this tutorial assumes you are in fact including audio recorded from your microphone in your screencast.返回到屏幕上的優惠 ,這一次單擊設置按鈕在麥克風包含田徑節。 注:本教程假定您實際上是包括音頻記錄您的麥克風在您的screencast 。
From here you can change the default audio format, but again, the default is ideal.從這裡您可以更改默認的音頻格式,但再次,默認是理想的。 However, you may want to change Mono to Stereo for better sound.不過,您可能要變更單 ,以更好的立體聲音。
- Once you’ve recorded your screencast with Snapz X Pro, launch ffmpegX.一旦你記錄你的screencast與Snapz X專業版,推出ffmpegX 。 Click the Open button from the upper left corner.按一下按鈕, 打開左上角。
- Navigate to the .mov file you created with Snapz X Pro, select it and click Choose .瀏覽到。 mov文件與您創建Snapz X專業版,選擇它,然後按一下選擇 。
- The default Target Format will likely be set to AVI DivX , but that’s not what we’ll want to use.預設的目標格式可能會定到 AVI DivX ,但是這不是我們將要使用的。
- So click the small arrow next to AVI DivX and select FLV (Flash Video) from the pull-down menu.因此,按一下小旁邊的箭頭的AVI DivX和選擇視頻( Flash視頻)從下拉菜單。
- The default Flash settings aren’t ideal, so we’ll make a few quick changes.預設的閃光設置並不理想,因此我們將作一些快速的變化。 Click the Video tab.按視頻標籤。
- In the Video parameters section, you will almost certainly want to change the Video Size , as it’s unlikely that it actually matches your source (.mov) video file.在視頻參數節中,您將幾乎肯定要改變視頻大小 ,因為它不太可能,它實際上符合您的來源( 。傳送)視頻文件。 Enter the appropriate size in the spaces provided.輸入適當大小的空間提供。 If you’re not sure what video resolution you recorded in using Snapz X Pro, navigate to the .mov you created, select it by clicking it once, and then hit Apple Key+i to get the file information.如果你不知道你的視頻分辨率記錄在使用Snapz X專業版,瀏覽到。傳送您創建,選擇按一下它一次,然後按下蘋果鍵+一獲得文件信息。
- In the More Info section of the File Info pane, look for the Dimensions .在詳細信息部分文件信息窗格中,尋找尺寸 。 That’s the video size you’ll want to specify in ffmpegX.這是視頻大小您要指定在ffmpegX 。
- Back in ffmpegX, select the Audio tab.回到ffmpegX ,選擇音頻標籤。 Use .MP3 as the Audio Codec .使用。 MP3播放的音頻編解碼器 。 You might want to increase the Audio bitrate slightly, but not too high - if your audio track is just your voice recorded through your microphone, there’s no need to have very very high quality audio.您可能需要增加音頻比特率略有下降,但不能太高-如果您的音軌就是你的聲音通過記錄您的麥克風,就沒有必要有非常高品質音頻。
When everything is set to your liking, click the Encode button.當一切設置為您喜歡,請按一下按鈕編碼 。
- The length of time it takes to encode your video will depend on the video size and length.長的時間來編碼您的影片將取決於視頻大小和長度。 I used a 41 second, 43.4MB movie file, and it encoded in about 15 seconds.我用了41第二, 43.4MB電影文件,它編碼的約15秒。
- Once completed, locate your newly created .flv (flash) file.一旦完成,找到您的新創建的。視頻(閃存)文件。 Notice the huge difference in file size (mine went from 43.4MB to 2.5MB).通知的巨大差異,檔案大小(雷從43.4MB ,以提供2.5MB ) 。 You can play your flash file in your browser, or a video player like VLC if you have it installed.您可以發揮您的閃存文件在您的瀏覽器,或視頻播放器可變長編碼一樣,如果你有安裝。 Note that the quality will have decreased slightly from the original .mov, but not significantly.請注意,質量將略有下降,從原來的。傳送,但不顯著。 And the huge decrease in file size more than makes up for the slight quality loss.和巨大的減少文件的大小超過彌補了輕微的質量損失。
- That’s it - you’re done.這就是它-即可大功告成。 Next up will be a screencast on how to embed your Flash video into a WordPress blog.下一步將是一個screencast就如何嵌入您的Flash視頻到WordPress的博客。
