Slow Motion Wipes
- Login to post comments
Hello,
I work on a Kayak HD switcher inside an OB van, we broadcast football matches, i was asked to make a wipe effect between live & slow motion replays, similar to the one used in UEFA champions league, a wipe with the logo moving with it, and because i'm not a very experienced vision mixer i thought i should ask the professionals :),
after giving it a thought, i figured that i have to make the logo animation clip, and load it to the RAM player, then chroma key this clip, and record a macro that runnes the clip and does the wipe transition simeltaneously (transition time should be the same as the clip length).
can anyone tell me if i'm right ? and please can someone give me a brief discription of how it is done ? what should the format of the clip be ? should i use chroma or linear key ?
your help will be appriciated.
Thank you for your time.

I suggest you to record a macro that: - cues up the clip (previously loaded. I don't know how much time it takes to load it, but I will assume you have already loaded and ready to play); - puts the M/E in wipe + key mode; - recalls the selected wipe (in case it is accidentaly set up incorrectly, this will recall the correct setting); - insert a minimum pause (0.1s should be enough, I have found this useful on the kayak); - does the transition (autotrans + clip play); - insert a pause a little longer than clip duration; - drops the key and puts the M/E in mix mode (slow motion from different sources will probably require mixing); - insert a minim pause; - recues clip. This will ready the switcher to play the wipe again to exit the replay sequence. This step is not necessary but I prefer to have the clip always cued correctly. I also need to trigger an external jingle machine and I do this putting the macro in a timeline the closes GPI contacts. I hope I did not forget anything :)
