The executable file aerender (aerender.exe on Windows) is a program with a command-line interface with which you can automate rendering. The executable file is located in the same folder as the primary After Effects application. The default locations:
Windows: \Program Files\Adobe\Adobe After Effects CS4\Support Files
Mac OS: /Applications/Adobe After Effects CS4
You can use the aerender application to perform rendering operations on multiple computers as part of a render farm, or you can use the aerender application on a single computer as part of a batch operation.
You use the program by entering the command aerender on the command line (or in a batch script), followed by a series of optional arguments. Some of the arguments are simple options that take no arguments of their own (for example, -reuse), whereas others take arguments of their own (for example, -project project_path).
The version and build number of the application are written to standard output (stdout).
The render may be performed either by an already running instance of After Effects or by a newly started instance. By default, aerender starts a new instance of After Effects, even if one is already running. To instead use the currently running instance, use the –reuse argument.
This example command tells After Effects to render frames 1 through 10 of Composition_1 in project_1.aep to a numbered sequence of Photoshop files using a multi-computer render:
aerender -project c:\projects\project_1.aep -comp "Composition_1" -s 1 -e 10
-RStemplate "Multi-Machine Settings" -OMtemplate "Multi-Machine Sequence"
-output c:\output\project_1\frames[####].psd
To render just Composition_1 to a specified file, enter this command:
aerender -project c:\projects\project_1.aep -comp "Composition_1" -output c :\output\project_1\project_1.avi
To render everything in the render queue with current settings in the project file, enter this command:
aerender -project c:\projects\project_1.aep
Argument | Description |
---|---|
–help | Print usage message. |
–version | Display the version number of aerender to the console. Does not render. |
–v verbose_flag | verbose_flag specifies the kind of messages reported: ERRORS : Reports only fatal and problem errors. ERRORS_AND_PROGRESS : (default) Reports errors and progress of rendering. |
–reuse | Reuse the currently running instance of After Effects (if found) to perform the render. When an already running instance is used, aerender saves preferences to disk when rendering has completed, but does not quit After Effects. If this argument is not used, aerender starts a new instance of After Effects, even if one is already running. It quits that instance when rendering has completed, and does not save preferences. |
–mem_usage image_cache_percentmax_mem_percent | image_cache_percent specifies the maximum percentage of memory used to cache already rendered images and footage. max_mem_percent specifies the total percentage of memory that After Effects can use. For both values, if installed RAM is less than a given amount (n gigabytes), the value is a percentage of the installed RAM, and is otherwise a percentage of n. The value of n is 2 GB for 32-bit Windows, 4 GB for 64-bit Windows, and 3.5 GB for Mac OS. |
–project project_path | project_path is a file path or URI specifying a project file to open. If this argument is not used, aerender works with the currently open project. If no project is specified and no project is open, the result is an error. |
–comp comp_name | comp_name specifies a composition to render. If the composition is in the render queue already, then the first instance of that composition in the render queue is rendered. If the composition is in the project but not in the render queue, then it is added to the render queue and rendered. If this argument is not used, aerender renders the entire render queue; in this case, only the –project, –log, –output, –v, –mem_usage, and –close arguments are used, and all other arguments are ignored. |
–s start_frame | start_frame is the first frame to render. If this argument is not used, aerender uses the start frame in the file. |
–e end_frame | end_frame is the last frame to render. If this argument is not provided, aerender uses the end frame in the file. |
–i increment | increment is the number of frames to advance before rendering a new frame. A value of 1 (the default) causes normal rendering of all frames. Higher values render a frame and use it increment times in output, and then skip ahead increment frames to begin the cycle again. Higher values result in faster renders but choppier motion. |
–OMtemplate output_module_template | output_module_template is the name of a template to apply to the output module. If the template does not exist, using this argument causes an error. If this argument is not used, aerender uses the template already defined for the output module. |
–RStemplate render_sett ings_template | render_settings_template is the name of a template to apply to the render item. If the template does not exist, using this argument causes an error. If this argument is not used, aerender uses the render template already defined for the item. |
–output output_path | output_path is a file path or URI specifying the destination for the final output file. If this argument is not used, aerender uses the path defined in the project file. |
–log log_file_path | log_file_path is a file path or URI specifying the location of the log file. If this argument is not used, aerender uses standard output (stdout). |
–sound sound_flag | If sound_flag is ON, a sound is played when rendering is complete. Default is OFF. |
–close close_flag | close_flag specifies whether or not to close the project when rendering is complete, and whether or not to save changes: DO_NOT_SAVE_CHANGES : (default) The project is closed without saving changes. SAVE_CHANGES : The project is closed and changes are saved. DO_NOT_CLOSE : The project is left open if using an already-running instance of After Effects. (New instances of After Effects must always quit when done.) |
-rqindex index_in_render_queue | -rqindex works just like -comp, except that it won’t create a render item from the composition automatically. |
-mp enable_flag | If enable_flag is 0, additional processes are not created to render multiple frames simultaneously. If enable_flag is 1, additional processes may be created to render multiple frames simultaneously, depending on system configuration and preference settings. (See Memory & Multiprocessing preferences.) |
-continueOnMissingFootage | The render operation continues even if a source footage item is missing. |
Lloyd Alvarez provides a script on his After Effects Scripts website that takes items that are ready to render in the render queue and sends them to render in the background using aerender.

1.做好分類整理可強化記憶力 |
在記憶的目標對象雜亂而眾多時,必須把記憶的對象分類、整理,這樣的記憶效果最好。儘管進行分類時要花費一些時間,但因便於準確地記憶和回憶,而且會節約時間,結果還是合算的。著名心理學家米爾教授曾對「記憶」進行無數次實驗,得出非常有趣的結論,即,一個人一次記憶的最大限量是「七」。 只要是七以內的數量,其內容不論是單詞,或其它同類的集合體,都一樣能記住。在必須記憶許多事情時,就可以利用這個方法,把性質相同的詞編成一組,每組七個以下,這樣的記憶效率就高。如再把每組加上標題,則更能牢固地抓住整體的概念,提高自己的記憶能力。 |
2.對於無意義的事務要賦予意義來記憶 |
要你背NPDOYVKEWQH這十一個英文字母,其實並不容易,如果你記憶TIME IS MONEY就很容易記了。雖然是相同的十一個字母,有涵意的就容易記憶;因此,你一定要重視「有意義的東西」,因為它比那些無意義的東西容易記憶。 在國中的時候,數學要記平方根、圓周率等等,如果一個字一個字強記的話,的確很累,一般人都會使用同音聯想法來記,到了高中,這種方法仍然適用,像化學週期表、歷史合約國等,同音聯想會給唸書帶來娛樂效果和牢記不忘的成就感。 複雜的文章。或許可以改成圖或是表,使人一目瞭然。這與指示別人路徑是一樣的道理,用嘴巴講老半天,不如書一張地圖,對方看了更容易了解。 |
3.很多東西並不定要去死記死背 |
專家說︰「只要把骨幹部份理解了20%以上,那麼對於枝葉部分80%的細節解釋,就八九不離十了。」由此看來,純記憶性的要素是相當少的。 如果你仔細去思考一下內容,並了解記憶的步驟及過程,懂得這個法則後,腦筋裏面的記憶容量自然會擴大。 比方說你認為把那麼厚厚的一本六法全書每項條文都背起來 了嗎?那是很難辦到的,也沒人能把過去的判例全部記下,因為這根本是不可能的。對於律師來說,重要的是如何根據條文把現實問題給予詮釋。在法律的解釋中, 其實並不是單純死背條文及判例,只要把基本原理了解了,就不會有錯誤的判斷。 |
4.死背是最壞的學習方法 |
很多人以為「頭腦好」與「記憶力好」是成正比的,這種想法可能使得你的學習方法錯誤。常常有人認為自己的記憶力很壞,而認為即使再努力也沒有用,那更是大錯特錯! 死背是一種很笨拙的學習法。但是只要你知道一定規則的話,就會比死背輕鬆。例如一加一是二,二加一是三,這樣在某數上面加一,就會成為多一個數值的數字。了解這個法則,就不必記五加一是甚麼,一個個死背了。 有些人懶得用頭腦去思考法則,只會說「沒辦法了,只有死背答案。」死背的東西忘了以後就是忘了,再也不能回復這部份的記憶。但只要你了解到「解答」的基本原理,就不會忘掉。就算忘了,也可以用這個原理及法則再回憶起來,理解是最好的學習方法。 |
5.反覆思考才能保持記憶 |
為了不把學過的東西忘掉,必須常常回憶一下,並給予再確認。例如在課本重點的地方做記號,反覆多看幾次,或者是製卡片。只要有空就拿出來看。 有一位學者作過這樣一個驗試:他把所有無 意義文字的紙製成卡片,讓被試者記憶這些文字,二十分鐘後加以測驗,結果發現受試者只記得58%而已。到了次日,受試者幾乎又忘了將近三分之二。但是另一 個學者做了另一種實驗,要受試者把記得的事情在一個鐘頭後一條條地再複習確認,結果經過了兩天之後,受試者仍記得75%左右。 因此你就可以了解:記憶後不久再予以複習確認,這種記憶方式的效果很好。運用「凡記憶過一次的事情,不久後再給予回憶並確認的話,就很難忘記」的原理,在需要強記的領域裏,是暢行無阻,最有效的方式。 |
6.把沒有必要的東西忘掉,才能加深其它記憶 |
要如何在短時間內記憶許多事情呢? 首先,在開始記憶之前,先「想一想」,哪些是以後有用的?哪些是沒用的?哪些不必要的事情可以捨棄在一邊?要養成這種想一想的習慣,就能從雜亂的訊息中,把真正對自己有用的東西盡快地、準確無誤的篩選出來。 下一步,是將必須記憶的事項,按性質進行 分類、歸納、編組。這樣,以後只要回想起某一組事物,也就能很容易地把其中某一事件回憶出來。或者,要是把編成一組的事物,再編寫成短文或小故事,其效果 會更好。如能再將其內容描繪成畫面深印在腦子裏,將更能輕鬆地記憶,並更加容易回憶出來。 |
7.出聲朗讀有助記憶 |
若想要記憶一些東西,出聲朗讀較容易記憶。特別是當大 腦處於膨脹、不清醒狀態時,高聲而清楚地朗讀效果更好。因為發出聲音朗讀,能促使肌肉運動,刺激大腦。使大腦保持緊張,其它事物就不可能在大腦中浮現,注 意力會集中到一點上,從而形成記憶狀態。並且,由於自己發出聲音和聽自己的聲音音兩種活動同時進行。兩種器官同時開動,所以對大腦的刺激效果就能增強。 看英文報紙、雜誌等對提高外語的閱讀能力可起很大的作用,當然還是讀出聲為好。在公車上大聲朗讀是會打擾到別人,但在自己的房間裏朗讀就沒關係了。即使遇到不懂的單字也先不去管它,只作朗讀訓練,最後再查字典弄清字義,這樣自已就能逐步完全掌握了。 |
8.音樂有助增強記憶力 |
香港中文大學心理學系在去年完成的一項研究顯示,試驗者若從小開始學習彈奏一種樂器,可同時增強對語言的記憶力,實驗發現他們記憶語言的能力比小時沒有學習樂器的人高出17%。 語言記憶力在學習過程中是十分重要的原 素,但很多增強記憶力的方法都比較單一呆板。這項研究指出,學習音樂對語言記憶有著正面而長遠影響,而學習音樂本身對小孩子來說是一項有趣的活動。陳教授 說:「學生如能寓學習於遊戲,在享受音樂的同時,不知不覺間增強語言記憶能力,對將來學習大有裨益。這個發現,相信對傳統的強記方式有很大衝擊。」 |
9.增強記憶力的營養品 |
維生素B1、B2 維生素B1、B2的功能,是將吃下的營養轉化成可吸收的養分,若體內沒有足夠的維生素B1、B2,吃再多的補也是徒增負擔! 藍梅 藍梅所含的天然抗氧化成份,有助於提升人類平衡感、協調能力與短期記憶力,類似的食物如草莓、菠菜亦有此效果,但以藍梅的效果為最佳! |
卵磷脂、銀杏葉提煉物 這兩種健康食品本來是用來防治老人癡呆症,但相關研究亦顯示卵磷脂、銀杏葉對於記憶力強化的功效不限於老年人,年輕人吃了一樣有幫助。 |
10.有氧運動,幫助腦內協調功能提升 |
頭好壯壯的前提是腦內血液循環順暢,有氧運動能幫助腦內血液含氧量提升,不僅對於四肢協調功能有所助益,同時對記憶與思考功能也有提升效果。 |
