Video transitions

Tr742

hi

Have been using and programming Izzy for a few years

I use it in theatre for a music show with band. I use izzy for visuals.which we project 8 metres wide on screen behind band Via video player and projector with audio stereo l click for musicians R for audience.
i mix from scene to scene with a simple jump actor performance is not good . No matter what setting I use transition time my transition goes to black and jerky

in fact the only time I achieve a good performance of this is when going from holding slide to holding slide then its smooth as silk rather than video

Is there something I’m missing or a quick fix

Or is it a big ole can of worms to fix

Dear Arthur

Well its difficult to say, because we do not know at all what you are working with.
Mac or PC?
What OS version are you using?
What Specs does the computer have?
Isadora 1,2 or 3?
What codec and resolution does the movies have?

I guess you mean .h264 not .h267
What resolutions are the movies?
What are the specs of your Mac (what processor, how much RAM, HDD or SSD?

Never heard of HCF batch converter. A very good alternative would be the AVF batch converter https://docs.vidvox.net/freebi... or Handbrake https://handbrake.fr

additional questions:
Whats the data rate of the movies? (if you open them in Quicktime hit cmd+i the inspector window will open where you can read the data rate)
Whats the frame rate of the movies? (you can also see that in the inspector window. Do all movies have the same frame rate?)
What frame rate have you set in the Isadora preference settings in the "General" tab? Do they match the movies frame rate?
What have you selected in the "when combing video" settings in preference "Video" tab?
In the Mac's preference setting: what's the resolution and refresh rate set for the connected projector?
are you connecting with HDMI or VGA cable?
