Frequently Asked Questions

Why is 720p or larger CRT resolution so slow ?

When trying to use high definition resolutions for the virtual CRT screen, the idea of the application is misunderstood. The program simulates an analog television/vhs signal that (in real life) would be NTSC/PAL resolution at best. Instead, the render window can be set to 720p or larger without limit, and by setting virtual screen position and pixel size to correspond the HD window where it's presented, it's possible to render in 720p, 1080p or better resolutions. The overlapping pixels are just larger, but the post-processing shaders are more high definition.


Output has annoying lines over the picture

Some display adapters can't handle pixel blending the correct way, resulting lines on pixel borders. This usually happens with adapters not able to handle OpenGL 4.0 and later. One way to get the screen smooth is adjusting the screen zoom, pixel size and giving a slight blur shader from the Extra view.


How to open file or webcam source ?

This is described in the internal manual: From the top program menu bar, select Source -> Open Camera/Stream/File. After selecting the source it's assigned into the open Source part. Now switching the Source part Online will start the source playback.


How can I render the output in H264 on Windows ?

In order to encode video to H264 on windows, OpenH264 must be installed to system. It can be found here Get the 32bit windows dll version and put it into your system folder (recommended), or into Cathodemer folder.
