![]() ![]() Here is another post which i believe has done similar to first step i mentioned(i haven't tried the code mentioned by OP there). There are enough examples in the library repository so i'm not posting any code here. this dropped frames are not always noticeable so you might get away with it. but still, this will reduce the difference between stream lengths. as the library isn't encoder/decoder so you can only cut/trim a whole frame(audio or video). So before stitching videos you can cut/trim longest stream to match the other stream using the library. ![]() when you stitch more that 4-5 files, audio and video will get out of the sync. So you will have multiple mp4 files that you can then stitch together using Mp4Parser.Įach stream in Recorded mp4 file will have different length (difference will be in ~100 ms. but you can concatenate or trim a stream, switch streams or add streams to mp4 container etc.įor Implementing Pause/resume functionality you can use MediaRecorder for creating new recorded file every time user presses pause(and then resume). When you’re ready to save the video, from the QuickTime Player menu, select File > Save.Mp4Parser is java based library that lets you manipulate h264 and aac encoded streams. QuickTime Player opens with your recording. If you connected a microphone to your computer, speak into your microphone to capture the sound.Īfter you complete the actions you want to record, tap Stop in the Mac menu bar. The recording begins as soon as you select the area you want to record. Record part of the screen: Click and drag to create a rectangle over the area you want to record. Record the full screen: Click anywhere on the screen. The SMART Recorder automatically hides in the Mac menu bar and you must do one of the following to select the area you want to capture: Tap the arrow next to the Record to select the microphone you want to use to record sound (or select None to record no sound) and choose whether or not you want mouse clicks to be captured in the recording. You can still access the SMART Recorder if you’re not connected to an interactive product. If your computer isn’t currently connected to a SMART interactive product, the SMART Board icon includes an X in its lower-right corner. Select a lower setting in the Colors drop-down list. Select a lower setting in the Resolution drop-down list. ![]() Tap Display, and then tap Change display settings. To reduce the screen resolution and display colors I couldnt really find anything on this in the search, so Id like to know if its permissible to pause while Im recording a demo Ive only read somewhere that its not recommended (perhaps because of possible sync problems) but can it be seen as a form of cheating Of course, itd be nice to be able. PCI Express cards generally provide a faster performance than Accelerated Graphics Port (AGP) or Peripheral Component Interconnect (PCI) cards. Some video cards perform better than others. ![]() Network drives are slower and reduce performance. Smaller screens and fewer colors result in faster performance. Reduce your computer’s screen resolution and display color settings. Higher video quality produces larger files and places higher demands on your computer. You need to balance your expectations for video quality with your computer’s limitations. If your system performance is slow when you use SMART Recorder, or the recording quality isn’t the standard you want, the following may improve performance: ![]()
