I am looking for a way to synchronize on stage for a band :
a master track containing some samples
a click track (for the drummer)
a video (through HDMI to a digital projector)
I need reliability and sync between those 3 tracks.
I tried many ways in windows and linux, and nothing has been really stable.
I tried a live usb of ubuntu studio, and ardour+jack+xjadeo gave me a pretty good result !
I have a few questions
I wanted to know if some people already used ardour for this, and what was their results
is there a max video file size (as only one video can be loaded, I will need my entire show on one video) ?
what is the internal codec and settings used by Ardour in its transcoding ? I would like to skip this to avoid quality loss
Are you missing a feature from ardour+jack+xjadeo?
I think you want lots of keyframes in the video. I think ardour imports, it makes it mjpeg at a lossy quality.
But I think if you don’t import it, and just run xjadeo separately to load the video it should be good. I wouldn’t interact with ardour once it starts and just let it run with xjadeo running on the 2nd screen/hdmi output.
Does the video have audio already? If not, you could probably replace the audio on the video file to be a click track and then the drummer is the only one listening to the audio.
No, there is no limit, except 24h timecode rollover. But if you use a USB-key with VFAT, keep in mind that the file-system has a 4GB file-size limit.
The proxy video uses avi/mjpeg, because it is fast to seek around randomly (every frame is a keyframe).
When you play linearly and rarely seek, mp4/x264 is fine. But keep in mind that xjadeo has no hardware decoder acceleration. large geometry (e.g. fullHD) can be heavy on the CPU.
