Wireless Digital Video:Recording and playing

Recording and playing videos
- The recording area from the menu will allow to record all your videos on the local SD Card. TX shows that the recording will be done on the transmitter's SD Card. RX indicates that the recording will be done on the receiver's SD Card.
- Master mode (MS) is required before the REC button is enabled. Check link modes page for more information about linking modes.
- Clicking the red button the device will start recording.
- The disk space shown is the space left on the SD Card. The recording will stop automatically once the card is full.
- Each recording will create a MKV file on your SD Card which is playable with any conventional video player.
- Important: Because neither the transmitter nor receiver include a backup battery you need to stop the recording before shutting down the device. Failing to do so will result on losing the last seconds of your recording and will not close the MKV file. If the MKV file is not closed, the video player will not be able to search while playing and you will be forced to play the video sequentially. The file can be closed later with a PC in case you forgot to stop the recording. An example on how to close a MKV file using ffmpeg:
ffmpeg -i 00032.mkv -vcodec copy video_seek_fixed.mkv
- At this stage the devices do not support playing the videos so you are required to extract the SD Card and insert it into your computer in order to see the recorded videos.
- All the videos are recorded on the second partition of your SD Card. This partition is an EXT4 Linux partition. PCs running Linux will not have any problems mounting and reading this partition. Microsoft Windows users will require a third party tool to read these kind of partitions. More information can be found here.
