  • Flickering On External Monitor While Trimming

    I have an external monitor (actually it's an LCD TV) connected using component cables from my NXe card. The picture is usually fine, except when I edge trim clips on the Edius timeline. Then it flickers like crazy, in fact it is more like flashing, i.e. video frames alternating with black frames (difficult to be sure because it is pretty fast). You can still see the video change correctly as the clip edge is moved, but it is very uncomfortable to watch.

    The preview window on the main PC monitor is OK, only the external monitor does this. Any way to stop it happening?

    Is this on a interlaced or progressive project?

    Is your Pause view set to Upper/Lower Field or Frame?

      Hi Rusty, thanks for the reply.

      This is an interlaced (50i) project, footage is from a Canon XH-A1. I already tried changing the Video Overlay setting under hardware, but both Field and Frame gave the same results, i.e. flickering on external monitor. I realise video overlay should not apply to external monitor but that's the only field/frame setting I found. I'll see if I can find Pause View.

          also, what external monitor are you using? Tube type? LCD? Plasma?

            Hi Anton. I tried all the Pause Field options, but it didn't make any difference. The monitor is a Samsung 19" widescreen LCD TV. Normal playback is fine, it is only when I drag the edge of a clip to trim it that the picture flickers and flashes.

              it does not shake here on a 42" Plasma connected via component out

              but it shakes on the Edius preview window while trimming, I reported this and was told that this is normal

                Ha ha, my preview window is stable but the external monitor is flickering. I suppose someone will say this is normal too. :) OK, thanks Anton.

                  Are we talking about two different things here? Anton's is the preview window on the computer (his plasma is fine) and Richard's the external monitor. I'm confused.
                  Is this the inability of the NX card to handle component output or something to do with poor software?

                    if your trim the start of a clip, push the right arrow key once after trimming, does the flicker go away?

                    if your trim the end of a clip, push the left arrow key once after trimming, does the flicker go away?

                      Hi Anton. If I trim a clip and then stop, the image I see is like 2 fields alternating. Then when I press an arrow key, the preview updates to show what is at the cursor position. Whether it flickers or not depends on what I have selected for Pause Field (Frame causes flickering when there is movement between the fields).

                      But this alternate-field flickering at the end of the trim is not what I was originally asking about. My problem is that during the trim, as I drag the edge of the clip, there is a lot of wild flicker and flashing that is not easy on the eye. It's as if there are irregular blank fields or frames mixed in with the normal video.

                      Think I'll have to revert to editing with my eyes closed.

                        I have not noticed anything you just described, however I hardly drag the edge of the clip, I find it easier to drag the CTI to a point where I want to trim and hit M or N

                          Sounds to me like the TV itself is having issues with the signal being sent out.

                          Does this behaviour occur in any project setting? SD, 720p, 1080i?

                          Also, do you have another TV to quickly test with? It doesn't need to be a super duper TV, just something capable of video input from the NX.

                            Also, does your LCD TV have any interlace/Hz correction or optimisation options? Things where it automatically tries to correct a picture for better display.

                            (I always turn that rubbish off)

                              I agree that something in the signal must be upsetting the TV. I don't have any 720 projects, only 1080 or SD. Can't remember if it happens with SD, will try it and see. But I don't think that will help the HDV project unfortunately.

                              I will also check the TV settings but from memory there is nothing much to adjust. Thanks for the reply.
