A video won't play or stutters
What to check when a video won't start, stutters or has no sound.
“Couldn't play the file”
The projector couldn't open the video. The notice says “Couldn't play ‘…’ on the projector”, and its row says Couldn't play. The app leaves what's on screen alone so you can decide what to do: send something else live or click LOGO. The format usually isn't the problem, since anything the regular player can't open (AVI, WMV, ProRes…) plays through the app's own engine (how). Make sure the file isn't damaged by trying it in Preview or another program, and if it plays fine there, report it. On Linux, check that libmpv is installed (how).
It stutters or skips
Try it in Settings › System › Test video, which tells you whether the computer can handle it. It works with common formats (MP4, MOV, WebM…). AVI or WMV files, which the app's engine plays, can't be tested there.
Turn off Moving video on the Live monitor in the same section. The monitor stops playing a second copy, and the projector isn't affected.
On a laptop with two graphics cards, choose the more powerful one for Himnova Live in the Windows graphics settings.
Close other programs.
Tip: If the Live monitor says Moving video off, nothing's wrong. Moving video on the Live monitor is just turned off, and the projector plays the video normally.
There's no sound
- Check the volume and Mute on the video's row under the Live monitor. A video inside a slide has its own row and volume.
- Check the Starting volume in Settings › Projection. That's what every video starts at.
- In Preview, the volume starts at 0 for each video. Turn it up on its row.
- BLACK and LOGO pause the video. Click LIVE.
- Sound plays through the computer's audio output. Choose the speakers or HDMI in your system's sound settings.
