However, one of the crucial problems is the assumption, that the frame rate of the two incoming videos is equal - in reality, usually the desktop capture is of a lower framerate and even worse, very often frames are out of sync. Well, there are many troubles in this process under Ubuntu Lucid, which I currently use ( and you can read about some of my ordeals in 10.04: Video overlay/composite editing with Theora ogv - Ubuntu Forums). This is also why I like to have the 'desktop capture' video as a PNG sequence (although I guess any uncompressed format would do): I take measures to 'adjust' the desktop, so there aren't many gradients, and lossless encoding (i.e. ogv codec - which is why I'd like to keep the original videos, and use something like a command line to generate a 'final' video anew, if a different compression/resolution is required. In principle, I guess one could use a command line tool like ffmpeg for this process however I would prefer to use a GUI for finding the alignment start point for the two videos.Įventually, what I also want to achieve, is to preserve maximum quality when exporting the 'final' video: the 'live' video is already compressed when out of the camera, which means additional degradation when it passes through the Theora.

Export a 'final' combined video, compressed appropriately for the Internet.

(where a portion of the screen on the 'live' video, serves as a visual sync source with the 'desktop capture' overlay).

Set up a picture-in-picture, where a scaled down version of the desktop capture is put - as overlay - on top of the 'live' video.

align the time of start of the desktop capture, with the matching point in the 'live' video.

The idea, then, would be: if the frame rate of the two videos is the same then I could simply AVI video and I want to get the desktop capture as an image sequence of PNGs at the same frame rate as the video. The video camera produces a 29.97 (30) FPS MPEG-2. My strategy, for now, is to use a video camera to record the process of hardware testing ( as 'live' video) - and do a desktop capture at the same time. A chunk of an intro follows, before I get to the specific detail(s).

Any other suggestions for desktop screen capture - but 'correctly timecoded'/ with unjittered framerate (with a stable period) and with possibility to obtain it as uncompressed (or lossless) image sequence?īriefly - I have a typical problem that I am faced with: I sometimes develop hardware, and want to record a video that shows both commands entered on the PC ('desktop capture'), and responses of the hardware ('live video').What is the framerate of VNC connection (in frames/sec) - or rather, who determines it: client or server?.

To use this feature you need the new version of VNC Connect, available for Windows, MacOS, as well as Linux.Ī short video version of this tutorial is also available. Share the location with your colleagues and you’re all set. Then, you can copy the file to a shared drive, or even a cloud storage service, like OneDrive or Dropbox. All you need to do is to go to the location you’ve set in the first part of this tutorial. You can also share your recordings with colleagues. You will find the resulting file in the location that you’ve set in the Preferences menu.

Once you click the button, the software will start recording your session. Once connected, click the red Record button on the toolbar. Depending on your VNC Connect security settings, you might need to authenticate. Start VNC Viewer and access the machine you want to record a session on. You’re now ready to start recording your screen. Now that everything is set, you can start using the feature. If you’re using the feature for auditing purposes, you might want to Record all sessions. You can also select the folder every time you start recording. The latter will be especially useful if you want to come back to your recordings later. You can also click Show in folder to access the respective folder. Under Recordings you can see where the software saves files by default. Start VNC Viewer, then click File > Preferences, as seen below. There are many use cases for this feature, including auditing, training or quality control.
