load of video file

[Matt Weber]

Hi, I'm trying to work out preloading some long video (movie) files in a cue list.  What I've tried is adding a couple of load cues before the preshow music.  This loads the videos as expected but once I trigger the pre show music group the movie files are no longer loaded.  Is there a way to keep these cues loaded?  Do I need to restructure my cue list?

I also put a load cue before the movie file but trying to get them loaded when I don't have to be concerned about a long load time.

BTW the videos are pro res proxy 422  :-)

I currently have something like:

Load Cue A

Load Cue B

Preshow Tracks Group (with autoload mp3 files to fade group)

Coming soon video 1

Coming soon video 2

preshow announcement audio

Long Movie File (A)

Intermission Tracks Group

Another Long Video File (B)

Thanks!

No reason at all why that should happen (see attached screen recording)

Once your video files are loaded only stopping the cue list will unload them.

This could happen if you press ESC, or if any of your other cues have a fade and stop list programmed in their triggers tab

However, a 2 hour video file takes no more time to load than a 2 sec one, so I'm not sure why you need to preload them in advance. If all your cues were set to auto load then your first long file would load as the announcement audio cue played, and the second long video would load as you faded the interval music.

You usually only need to manually manage pre loading when you have groups that start lots of cues simultaneously. e.g if you had a group that started 20 sound effects and 8 videos to 4 screens, if they all auto-loaded at once when the cue before the group was triggered then they might affect the playback of that cue.

Also, if you are just starting a single video file from a state where nothing else is playing, it should start  near enough instantly anyway even if it is not preloaded.

I know esc will unload everything so I'm avoiding that.  I was seeing load/start times significantly longer which I was attributing to the movie being almost 4 hours long (old classic) even loading from a  Samsung T5 SSD.  Now I'm seeing quick start times where before I thought it was taking about 10 seconds to start playing.  Maybe restarting Qlab?? No clue.  Still curious why they don't stay loaded when I run the pre show music but like you mentioned it now seems to be mostly a moot point.

Thanks for replying.

Post  just your .qlab4 workspace file  (without the content files) and I can probably tell you why it's unloading.

Here it is.  The only strange thing with the file is the disabled camera cue.  I'm using that an option/placeholder for a preshow ad sequence.

You have fade and stop peers ticked in the preshow group cue.

The group cue is at the root level of the cue list, the same as your video files, so your video files are the peers and unsurprisingly will STOP as instructed.

Ugh, thank you for pointing out something I didn't think of.  That's what I get when I keep reusing and updating a movie cue file.  I forget about settings I've done for a particular reason for another movie showing.
