      Hello,

      I'm using isadora with 2 movies players and 2 live inputs in full Hd 1920*1080.

      I partly use isadora as a video mixer. So I must preview what's going out of the 4 sources before mixing it.

      I saw that my FPS are not good, and I saw that the preview itself was consumming a lot of ressources : four 1920*1080 streams to calculate, but I just need smaller streams for the preview.

      I can't change resolution on preferences because it would lower all the resolutions in the whole patch.

      Is there any possibility to lower the resolutions in one part of the patch ?

          'scaler' actor, resize video to any size you want.
          Paired with the 'Get Stage Size' and calculator, you can scale to a percent of the final output size.

            Hello dusx,

            Thank you for your answer.

            Maybe I'm wrong, but lowered scale video seems to still be processed has a full HD one..

            My fps is lower.

            Is really scale actor useful to lower resources consumption?

                Why don't you use the stage preview?

                      I used to. But the floating windows does the same job with less resources.

                        Even if you lower the refresh rate of the stage preview to 12 or even 1? You don't need it high for a preview.

                          The preview in controls need to open a floating window or an output on a projector. Am I wrong?

                          If so it works in full frame rate anyway.

                            If you double click the "Stage Preview" in controls in edit mode you can set the refresh rate in the settings window.

                                OK.

                                But since the scene must be activated, it needs a full processing even if the framerate is lowered? Am I Wrong?

                                Or is it possible to view this preview without activating the scene itself?
