The Recorder module¹ records video from any source together with audio from any audio device directly to the hard drive in various formats. Right click the module to open its popup menu. The following additional menu entries are available.


Record/Pause

Starts/pauses recording. Recording starts when the tally turns red.


Stop

Stops recording.


Settings

Opens the Settings dialog where the file format can be selected. Currently 5 container types are supported: Matroska, MPEG-2 Program Stream, MPEG-2 Transport Stream, MPEG-4 and QuickTime. Note both Matroska and MPEG-2 TS have the advantage that the file will always be readable, even if it is not properly closed (e.g. if a power outage occurs during recording). Matroska is also the only container that supports uncompressed audio (PCM). The video codec is automatically selected based on the container type: the MPEG-2 containers use the MPEG-2 code, all other containers will use H.264. The video bit rate is variable to keep a constant (high) quality. The video compression setting also affects the bit rate, where the low setting results in the highest bit rate and the lowest CPU usage. This setting is only used for H.264 compression and has no effect on MPEG-2 compression. Best video quality is achieved by selecting RGB444 as colour space, although not every video player supports this. Same goes for MPEG-2 which is not supported by the default Windows Media Player. The audio codec (AAC, AC3, MP3 and PCM) is manually selected as is the audio bit rate. Use the Audio Delay setting to obtain perfect audio/video sync in recordings. Typically audio will be early as video takes longer to process, so a positive audio delay should be set.


Save Recording To

All recordings will be stored in the folder selected here. The file will be automatically named VidBlasterX_yymmddhhmmss, e.g. VidBlasterX_140818143000 on August 18th 2014 at 2.30 PM. When more than one recorder module is used an additional index will be added to the file name (e.g. VidBlasterX_140818143000_1). The default folder is the "My Videos" folder. For optimal performance, especially with HD video resolutions, it is highly recommended to select a dedicated SSD drive here.
