In this case, Windows Media Player will shrink the picture to fit it on the screen. This cause the text and graphics to be blurry. To view the movie in full quality, you will need to switch Windows Media Player to full screen playback, or switch your monitor to a higher resolution .You may also record a smaller region to avoid this problem. Otherwise you may need to use the Movie Player software that is distributed with the CamStudio package to playback the movie.Another reason for the cause of the unclear image is the use of Lossy Codec as your compressor. This means the compressor will degrade the quality of your picture to reduce the size of your AVI file.To remedy this, you may either set the Quality settings in Video Options to a higher value, or use a Lossless Codec for your compressor (e.g Microsoft RLE is a lossless codec that is available only in the display mode of 256 colors).<\/p>\n<hr \/>\n<p><strong><a title=\"Previous\" name=\"Previous\"><\/a><span style=\"font-weight: bold\">I launch CamStudio but it does not work as well as in previous sessions. The symptoms are:<\/span><\/strong><\/p>\n<ul style=\"font-weight: bold\">\n<li>The flashing rectangle does not occur as frequently.<\/li>\n<li>The framerate decrease dramatically.<\/li>\n<li>The audio recording becomes &#8216;jumpy&#8217; or inaudible.<\/li>\n<\/ul>\n<p style=\"font-weight: bold\">I remember the first time I launched it, it does not have this problem.<\/p>\n<p>Your saved settings may not be well tuned or corrupted. You may want to reset your settings by turning off the <em>Save Settings on Exit<\/em> option, exit CamStudio, and launch CamStudio again.Alternatively, you may want delete the files <em>CamStudio.ini<\/em> and <em>CamData.ini<\/em> in your installed directory to reset your settings.<\/p>\n<hr \/>\n<p><strong><a title=\"CPUResources\" name=\"CPUResources\"><\/a>I record with the default settings of CamStudio and it uses up all my CPU resources. How can I free up more CPU resources for doing other stuff?<\/strong>In the default setting, CamStudio uses up all your CPU resources to achieve the maximum recording rate possible on your system. You will need to set this capture rate to be lower than the maximum to free up resources for other tasks.To see how fast your computer can go, try recording with a fixed region size at the maximum frame rate (the auto-adjust slider is set to the leftmost point in Options:Video Options). Take note of the Actual Input Rate when CamStudio is recording. This is the maximum frame rate achievable on your system at this fixed size.To free up CPU resources, go back to Video Options and set the capture rate (or playback rate) &#8212; using the auto-adjust slider &#8212; to be less than the Actual Input Rate noted earlier. If you are recording with the same fixed region size, your CPU meter will now show some improvements. <\/p>\n<hr \/>\n<p><strong><a title=\"TenMinutes\" name=\"TenMinutes\"><\/a>My recording crashed after ten minutes (or after a fixed amount of time). How can I prevent this?<\/strong>This is usually due to your temporary recording directory not having enough disk space. This is the location where CamStudio creates temporary files to store your video and sound data during recording. These temporary files can become very large and crash your system if you ran out of disk space.You can change your temporary directory for recording by going to <em>Options :: Program Options :: Temporary directory for recording. <\/em>You should always choose a directory that resides in the drive with the largest free space.<\/p>\n<hr \/>\n<p><strong><a title=\"Taskbar\" name=\"Taskbar\"><\/a>After I&#8217;ve minimized CamStudio, I am unable to find it in the taskbar. How can I restore CamStudio ?<\/strong>Starting from ver 1.2, CamStudio is minimized to the system tray instead of the taskbar. To restore CamStudio, double click CamStudio&#8217;s icon in the system tray. <\/p>\n<hr \/>\n<p><strong><a title=\"ThreadPriority\" name=\"ThreadPriority\"><\/a>What is the <em>Recording Thread Priority<\/em> option used for?<\/strong>(Options : Program Options : Recording Thread Priority)If you try to record the &#8220;Pinball&#8221; game that is shipped with some version of Windows, you will noticed that CamStudio will record only at a very low framerate when the Pinball window is set active. You can, however, improve the performance of CamStudio (at the expense of Pinball&#8217;s) by setting the <em><strong>Recording Thread Priority<\/strong><\/em> to <em>Highest<\/em> or <em>Time Critical<\/em>. This means you allocate more CPU resources to CamStudio by making its priority higher.Setting this option may also affect the performance of your whole system. Windows may no longer respond to some mouse clicks on your Desktop. For most cases, this option is best left at <em>Normal<\/em>.<\/p>\n<hr \/>\n<p><strong><a title=\"SaveDialog\" name=\"SaveDialog\"><\/a>When I press the shortcut key to stop the recorder when the program is minimized, the save dialog does not appear.<\/strong>Try minimizing all other windows on your desktop.

You can however, reduce the recording size (Region) to improve the frame rate.Another solution is to set the playback rate to be much higher than the recording rate (i.e speed up the playback rate). This can be set in <strong>Options :: Video Options<\/strong> and turning the auto-adjust option off. For example, capture frame every 20 second but set the playback to 40 frames per second.<br \/>\nWhen you are recording, please make sure your mouse movements and other behaviors to be deliberately slow.This allows CamStudio to record at a slow input rate, while speeding up the playback to make it more natural. The disadvantage is that you may need to take 20 seconds to record a 10 second movie.<em>In Options: Video Options, turn the auto-adjust checkbox option off.<br \/>\n<\/em><\/p>\n<ol>\n<li><em>Set Key Frames every 40 frames (typing manually)<\/em><\/li>\n<li><em>Capture Frames every 50 millseconds (typing manually)<\/em><\/li>\n<li><em>Playback Rate 40 frames\/second (typing manually)<\/em><\/li>\n<\/ol>\n<hr \/>\n<p><strong><a title=\"Recover\" name=\"Recover\"><\/a>CamStudio crashed halfway into the recording.

Because the algorithm works on a lossless basis, a very slight difference between pixels in each frame will cause the Producer to save data from each frame and render the temporal compression algorithm ineffective.<\/p>\n<p>What this means is that for an AVI to be effectively converted to a Flash file with maximal compression, your AVI has to satisfy certain characteristics. They should<\/p>\n<ol>\n<li>behaving a limited number of colors (i.e do not have many gradient-filled areas)<\/li>\n<li>not be changing much in between each frames, except for the mouse movements.<\/li>\n<li>be recorded in perfect quality (i.e the AVI images must not suffer degradation in quality when they are played back. A way to accomplish this is to use the MS Video 1 codec, with the quality set to 100)<\/li>\n<\/ol>\n<p>Most of the tutorials recorded with CamStudio satisfy the above conditions. In fact, when you choose the &#8220;Record to SWF&#8221; option in CamStudio Recorder, it automatically bypass some options and choose a lossless codec instead.<\/p>\n<p>Furthermore, if your AVI file includes an audio track, it is highly recommended that it is in the PCM format. If it is not, you may want to convert it to PCM first using a third party video editor (A good freeware is VirtualDub).<\/p>\n<p style=\"text-align: left\"><u>Please note<\/u> : The algorithm will not work very well with movies you see in the theatres. These images are usually saved with lossy codecs and change too much between frames. We , however, have plans to enhance the Producer so that it works with lossy images.<\/p>\n<hr \/>\n<p><strong>Can the Producer operate in command line mode?<br \/>\n<\/strong>Yes. The command to do so is<\/p>\n<blockquote><p>   <strong>producer -b c:\\folder1\\demo1.avi<\/strong><\/p><\/blockquote>\n<p>The resulting Flash file is stored in c:\\folder1 as demo1.swf<\/p>\n<hr \/>\n<p><strong>Can I use the SWF file produced by CamStudio in the Flash MX editor ?<\/strong>Yes, but you will need to use the Actionscript function (<strong>loadmovie<\/strong>) to load it. What this means is that you will need to create another Flash file that loads the SWF produced by CamStudio.This container file will manage, control, and enhance the original linear movie. Some possible enhancements include adding a custom preloader and control bar. You may also chain multiple SWFs produced by CamStudio with this file.In order to produce a linear SWF file that can be loaded, you will need to choose the following settings in SWF producer.<\/p>\n<ol>\n<li>Uncheck <u>Add Player Controls<\/u><\/li>\n<li>Check Autostart<\/li>\n<\/ol>\n<p>For more information, please refer to the help file.<\/p>\n<hr \/>\n<p><strong>Is there a limit to the size of a SWF file ?<\/strong>A Flash file has an inherent limit of 16000 frames (Macromedia Knowledge Base Technote 14437). For an AVI that needs more than 16000 frames, CamStudio will split the SWf into several parts, with the following naming convention :<em>basename.swf, basename_1.swf, basename_2.swf <\/em>&#8230;and so on.If you enable the <u>Chain Multiple SWFs<\/u> setting in the Advanced tab of the conversion dialog, CamStudio will link the SWFs so that <em>basename.swf<\/em> will load <em>basename_1.swf<\/em> when it has finished playing, and <em>basename_1.swf<\/em> will load <em>basename_2.swf <\/em>when it has finished &#8230; and so on.<\/p>\n<hr \/>\n<p><a href=\"http:\/\/www.ehelp.com\/camstudio\/faqs\/\">P\u00e1gina original desta FAQ.<br \/>\n<\/a><\/p>\n<hr \/>\n","protected":false},"excerpt":{"rendered":"<p>Uma empresa chamada Rendersoft desenvolvia em regime de c\u00f3digo livre o CamStudio (gen\u00e9rico do Camtasia), que grava em v\u00eddeo AVI ou Flash as a\u00e7\u00f5es que a gente faz na tela [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5,18,21],"tags":[],"class_list":["post-125","post","type-post","status-publish","format-standard","hentry","category-midias-digitais","category-video","category-windows"],"_links":{"self":[{"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/posts\/125","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/comments?post=125"}],"version-history":[{"count":0,"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/posts\/125\/revisions"}],"wp:attachment":[{"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/media?parent=125"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/categories?post=125"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/meiradarocha.jor.br\/news\/wp-json\/wp\/v2\/tags?post=125"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
