Decklink SP keeps crashing

[Mr_P]

its never successfully only using 1 layer with snap fades and movie files - you can only really get away with it using still images - even then, you can still get a 'flash' before the image is displayed, especially if its VERY large. Your best option is really to program it as an 'A/B roll' as you put it.

However, if you are still using a 0sec fade, depending upin the desk you are using, you may have to delay the intensity by 0.1 of a sec to allow the clip to load before you 'snap' to it.... this avoids 'flashes' when doing 0sec x-fades - also make sure you put the 'hidden' layer to zero - or none of the above will be effective.....

You probably need to build a preload of your "B" clip into your "A" clip cue but be prepared for a dropped frame or so as it dumps into RAM.

Hi again!

Today I´m having new problems. Whenever I try to change a clip in a layer, the system dips a frame or two in black before showing the new clip.

This worked fine yesterday... Isn´t the system supposed to change clips in an instant?

The problem practically is that I now need to go "A/B roll" on a long sequence instead of just choosing the next clip on the same layer...

Any ideas?

Thanks!

computer resources arent infinite - it takes time a little bit of time to load new clips. different codecs also load at different speeds.

if you dont want to A/B roll- make a longer movie with more of your clips in it-
its faster to access frames in a longer movie -than it is to load a new one.

in quicktime you can make a 'reference movie' which has file references but doesnt contain all the compressed frames - it refers to other files.

You do this in quicktime player.

Open all your clips in quicktime player -
then
1. Create a new empty file.
2. Start with clip 1 in front.
3. Type apple-A - select ALL - selects all frames
4. Select new empty file.
5. Type apple-V - paste - pastes all frames from clip one into new file
6. Select window with clip 2
7. Type apple-A - select ALL - select all frames from clip 2
8. Select new file -
9. Type apple-V - paste - pastes clip 2 onto end of clip 1.
10. ....repeat....

You have now created a new movie clip with all the clips in it.

Now save the movie - but select 'Save reference movie'.

This creates a small movie which references the other clips.

----

When you do this you must have all the original clips in the same directory as the Reference movie.

And total file cannot be longer than 65535 frames - a dmx limit on in and out frame values - which is about 43 minutes.

there was one test build of software a while back that crashed when video input was turned on/off -
