      Hi Michel

      Thanks for the pointers.

      I am still awaiting the actual content but hopefully tomorrow I wil have this.

      I have ben trying the syncactor with some test videos.

      I have a quick question. I am not a complete newbie but I am no where near your level with Isadora. 

      I am not sure which items I should be editing to ensure the videos stay in sync. When inside the actor, there are a couple of points but it is not that clear to me which is the best option to edit to ensure syncing. 

      What would be your normal things to do to ensure sync with the actor?

          Yes @dbini pointed it out right. You don't have to change anything inside the user actor.

            Hi


            I have to retract my earlier statement of not being a noob... That is so simple...... I was complicating the matter with delving into the actor.

            Thank you and apologies for the daftness.

            Very helpful as ever.

              HI all

              I am just following up on this.

              I have all set up and the sync works brilliantly.

              I have just hooked up the audio component and the second video is doing a lot of audio stuttering. This being a video I have never seen before.... I cannot tell if this is intentional or a byproduct of sync of the speed aspect of the 2nd movie player.... My guess is that is this as a result of the sync. I will have to check with the powers that be when they are back in tomorrow.

              In the interim, is there a way to "unstutter" the slave video or do I have to look at re-creating 1no. movie with both files??

              The codec behind them is Mpeg-4.

              I would be grateful for any advice.

                @eamon try ProRes or hap instead and if you can add all the audio tracks to one movie (this depends on your audio routing (if they go to separate outputs).

                It is always better to make one file with all the movies in it (so for 2 hd movies make a single movie that is 3840 * 1080 so 2 hd side by side). This works if the movies are the same length, it will be less overhead than doing the speed change on the second file, especially with h264. It will always be better than separate files and will give you dead lick sync.

                  Cheers for this. I had a feeling that I would be at this juncture due to how the sync plug in works.

                  Due to the videos being projected on 2 separate projectors/screens and mapped with Izzy map (pretty much squares but mapping is required), how can I map the videos correctly?

                  The videos are not side by side but approx 200mm from each other.

                     It does not matter actually, you juts feed the signal from a single movie player into 2 projector actors that go to different physical outputs. You can then use the mapper to grab each part of the video separately and map them as you need.

                      aha!

                      Sometimes I am too linear in my thinking.

                      That makes perfect sense.

                      I will give it a shot making the two video's into one master copy.

                      Thank you.
