Using screen and pan/zoom together

Sat Oct 16, 2010 4:08 pm
It's weird, in the past this has worked for me with no problem mostly in .7.7.1 but now I am using 0.7.8 and it worked yesterday with a video but today it's not. I have tried to apply the pan/zoom first, get it where i want it and then apply the screen transition but then the pan/zoom effect doesn't appear to be affecting the video. So then I try to apply the screen first and then the pan/zoom after that . It's like if I click the pan/zoom effect so it's highlighted in a red box, it plays the way I want in the preview monitor but as soon as it gets to the next clip despite the settings for pan/zoom being the same, it doesn't apply the pan/zoom settings. very odd! Any thoughts?

notice how first picture the pan/zoom effect is highlighted in a red box. the porkchopplatoon.com banner is at the top where i want it and all is good.

if I play the project and watch the preview monitor and it gets to the next clip of the watermark video, notice the red highlight box is not on the pan/zoom effect, and thus the pig head is not being affected by the pan/zoom video effect, it should be located higher in the upper right corner.

i've tried to just make the video watermark good to begin with as far as location of everything but everytime i export it as a 720x480 and import in and apply the screen transition it's never in the right location despite my source video being 720x480 and the video watermark clip being 720x480 as well. SO I am forced to use the pan/zoom video effect. I don't get this?

here's the final video, pig head and website banner is not where i want it. http://www.youtube.com/watch?v=iUA9QILQ6lg

does anyone know why the pan/zoom effect is not affecting my clip like it did in .7.7.1? the screen transition works but pan and zoom is not affecting my watermark video at all??? I tried going back to melt .5.6 and kdenlive .7.7.1 but i don't think sunab has his .5.6 melt PPA anymore cause when I tried it it said it wanted to install melt .5.4.

So the problem only appears in the combination screen + pan & zoom? Maybe it works using scale0tilt (use tilt to move it)

yeah, it's very weird. this combo of transition and video effect used to work just fine in .7.7.1. i'll give that other video effect a try. thanks

The combination of Pan & Zoom effect with screen transition works fine for me, but only when I disable the "on-monitor effects" or if I select the clip that does not have the pan & zoom effect (thereby removing the on-monitor rectangle control). I could not quite follow everything you described, I just tested that combination myself.

As far as the 720x480 overlay clip is concerned, maybe the problem is the pixel aspect ratio of that clip. See the clip properties, is it 1.0 or 0.888899? My test white circle-on-black mp4 is 0.888889 - the same as the project setting and the underlying NTSC DV clip - all are in agreement. However, I even tried mixing things up, like a 720x480/0.888889 overlay on a 640x480/1.0 clip in a 720x576/1.066667 (DV PAL) project, and my circle is still flush top, right. I do not know how you are triggering the problem.

i am unfamiliar with the "on-monitor effects". i will have to look into that. so you're saying i have to check that or uncheck that option on the video that the watermark overlays?

yeah, i previously tried solving the video watermark issue so that the pig head and website banner would be along the highest possible spot in the video watermark file but as I said when I create the mp4 despite the pig head being in the upper right corner and the website banner scrolling along the top, i export it as 720x480 but then when i lay it on top of some 720x480 video, its lower and not in the top right corner. never figured out why? I was also unaware of the clip properties. i will look into that also.

thanks for the suggestions.

here's the video watermark file which before i render it looks fine in kdenlive and everything is where i want it.

"on-monitor effects" is the change from a rectangle widget in the effect panel to a rectangle control overlayed in the preview monitor.

I downloaded it, started a new project as DV/DVD NTSC, added the pcp clip and a color clip, put the pcp clip on a track above, put the color clip on the track below, added a screen transition, rendered to MPEG-2, and all is fine. Does that work for you?

yeah, but what I am saying is that mp4 file has the pig head NOT in the highest upper right corner of a 720x480 clip. so i have to use the pan and zoom effect

I believe I understand what you are saying. Did you follow my steps to see if you get the same results where the result is that the pig appears in the same place in the rendered output as it appears in the standalone pcp.mp4?

yes, that's not a problem. it's the fact that i have to apply the pan and zoom effect to get the pig head higher in the top right corner and to also get the scrolling website address higher along the top edge. so what i am trying to say is that my kdenlive project with the pig head and scrolling website shows everything where it's suppose to be but after i render it to mp4 and then put that as an overlay on top of another video the pig head is NOT where it was prior to me rendering the watermark video you refer to as pcp.mp4. which is then why i have to apply the pan and zoom effect.

i still need to try to disable the "on-monitor effects" and see how that goes.

PS DId you see my other thread about the pan and zoom function acting weird and cutting off the bottom of my video despite it's size being 100% and it stating it's 720x480? that's another very weird thing in 0.7.8 where it didn't do that in 0.7.7.1

Ok, it sounds like the problem is in the output of the first stage where you generate the overlay clip. It sounds like the output of that is not what you expect. Have you viewed that separately (not on the timeline) to see if it is correct?

I am thinking this could be a problem with on-monitor effects and non-square pixels (720x480 vs 640x480). Going back to the original post and reviewing the screenshots, in the first screenshot you have the clip with pan & zoom selected, so it activates the on-monitor effects. In the second screenshot, the playing clip also has pan & zoom, but since it is not selected, the on-monitor effects is not active. Moreover, in the first screenshot, notice how the yellow rectangle control in the monitor extends above and below the active video region. I do not exactly know the footage, but that might be further evidence of the problem.

It will be helpful if you can test without on-monitor effects enabled in Settings and/or with using a 640x480 (VGA) project settings and overlay clips. I will keep trying to reproduce as my time allows.

ok, i tried to find where to disable the "on-monitor effects" for the clip that the video watermark sits on top of but i can't find it. I ended up using Scale0tilt (changing the Tilt Y dimensions a little) on the watermark video to get it so the pig head and website banner was more towards the top. As long as I have accomplished my goal with Scale0Tilt i'm a happy camper, it's just weird that the pan and zoom along with screen is acting differently in 0.7.8. Is this "on-monitor effects" something new?
