Sony Vegas is pretty picky with H.264 (AVC) files and it refuses to accept files produced with default settings, however converting your files with the previous command will do the trick and vegas will accept the file. To do so open your distribution's package manager and search for the package ffmpeg. Once the tool is installed, you can easily convert the file to a regular MP4 file with the following command (replace input_file.mp4 and output_file.mp4): ffmpeg -y -i input_file.mp4 -c:v libx264 -c:a aac -strict experimental -tune fastdecode -pix_fmt yuv420p -b:a 192k -ar 48000 output_file.mp4 To capture your desktop you will need the popular FFmpeg set of libraries installed in your system. You can do this as well in Windows, but you need to download manually the installer of FFMPEG and then add the directory to the PATH environment variable. The only solution is to encode the MP4 file with a regular codec using FFMPEG in Ubuntu, before using the file in Windows. Additional details on defining an area for recording Command Line You can get details about using recordmydesktop by viewing the man page. Using the Select Area on Screen function accessed by right-clicking on the panel icon. Solution (encode file to mp4 with regular libx264) Using the Select Window button and then select a window on your desktop. How can I record only one screen screencast desktop-recording Share Improve this question edited at 13:31 pomsky 63. When recording, the software captures both screens, but I only need to capture one. To easiest way to solve this issue is to re-encode the MP4 file/or other format again into MP4 but with FFMPEG using the regular libx264 codec. You can make a video recording of what is happening on your screen: Press Ctrl + Alt + Shift + R to start recording what is on your screen. We can record our screens using Ctrl + Alt + Shift + R, works very well. The problem lies basically on the codecs of the video generated by Kazam, Kazam's codecs are quite straight forward (H.264). But, when i return to the Ubuntu environment, the file can be played without any problem. In Ubuntu 20.04, if you simply want to record your screen without any of the bells and whistles, you can press Ctrl + Alt + Shift + R to start a screencast recording. I even tried to play the file in other player but it doesn't work in Windows. The file can't be played, so there's no preview available, sound or peaks, nothing. For my surprise when i tried to edit the video in Sony Vegas 13 in Windows: mp4 file into a USB and turned off my computer with Windows. Once the video was generated, i was able to play it in Ubuntu without any problem and it looked pretty smooth. The program is really simple and is easy to use, so the screen recording wasn't a problem for me. This utility can be easily installed with: sudo apt-get install kazam Optionally you can record sound from any sound input device that is supported and visible by PulseAudio. Kazam is a simple screen recording program that will capture the content of your screen and record a video file that can be played by any video player that supports VP8/WebM video format. This forced me to install a new useful utility named Kazam to record the screen. The other day, during the recording of a videotutorial for our YouTube channel, i needed to record the video directly from an Ubuntu operative system, not from a Virtual Machine.
