transition between images not smooth

[vince]

when a transition is placed it automaticly snaps to the image. but when you play the slideshow just before showing the new image it s showing in a flash the new image and then start the transsition. When i adjust the placement of the transition by -,02 the transition will played coorrectly.

another thig is that sometimes the trnastion cant be placed. when i restat openshot via terminal or menu the problem has been solved. i kow someone els who has the same problem.

i use ubuntu 9.10 64bits
openshot 1.00 (in sybaptic 1.0.0-1)

Same thing happens to me with 1.1.0

Thanks for the bug report. I have not been able to reproduce this. Is
there a series of steps that always produces this behavior? OpenShot will
also snap transitions and clips to the play-head, if it's close. So, maybe
your play-head is very close the edge of a clip, and the transition is
snapping to it instead. Just a thought. =)

I'll try to describe how to reproduce. I put a clip on track 1, then a clip on track 2 with a superposition of, say, two seconds. Then I add a dissolve transition. The left end of the transition snaps on the start of track 2, and I resize the other end to the end of track 1.
What happens is that it seems that the start of the transition is positioned 1 frame *after* the start of track 2, so that there is a flash of the track 2 content *before* the start of the transition effect. By moving by hand the start of transition a bit on the right the problem is solved.
Maybe a rounding problem? I will try to find time to two clips where it happens and put them on my web for you to check.

[Romano Giannetti (romano-giannetti)]

See for example http://www.rgtti.com/dataopenshot/oshotjump.tgz

I think that the problem is the snap sensitivity. When adjusting the position of the transition, it is difficult to snap it to the start of the clip on track #2.

...please tell me when I can delete the data from the server. Or can I just attach these files to the bug report? Which is the size limit?

[Jonathan Thomas (jonoomph)]

You can delete the data from you server now. I took a look at your
project. I can clearly see the transition is not aligned with the left edge
of the clip. So, if I click and release the transition, it snaps correctly
to the edge of the clip. In other words, I can confirm it's in the wrong
place, but when I touch it, the snapping works correctly and it goes to the
left just a bit and works fine.

What happens when you just click the transition and release it. Does that
fix it, or does it still jump to the right a bit? Also, be sure the
"snapping" is enabled, using the toggle button above the timeline.

Thanks!

OK, I think I got it. It seems that the snapping works ok when the "arrow" is selected, but is disabled (whatever the status of the magnet symbol) when I use the "resize" tool (the double horizontal arrow).
Is this as it is supposed to be? If yes, that is a little problem when trying to position the start and the end of a transition on two different edges.

when i have theproblems it waswith openshot 1.0. I will test it aigain en let you know if its works fine.

[vince (vincentfmvenema)]

still a problem with transition and fade out.

i add 4 photo's on track 2 (with automatic snapping). photo1 with fade in/out slow; photo 2 with no fade just 1 transition. What happens: photo1 fade in = ok fade out = not ok nothing happens. photo 2 a flicker of the photo and than the transition. (the flickering doesn't occur always)
photo 3 with fade in/out and photo 4 fade in and a transition placed add the end and changed direction. What happens: photo 3 fade in/out = ok. photo 4 fade in and transition = ok. When i add a transition to photo 4 at the begin than: photo 3 fade in = ok fade out = not ok nothing happens. photo 4 a flicker of the photo and than the transition begin and at the end. (the flickering doesn't occur always). When i adjust the transition with -0,03 it seams that there is no flickering of the photo before starting the transition. the adjustmewnt has no effect on the fade out problem.

What i notice is that after upgrading openshot to 1.1.0 i did the same thing as above and everything just works fine. in mean while a upgrade was installed i think of mlt but not sure. when i restarted openshot the described problems occur.

[vince (vincentfmvenema)]

I (re)installed openshot 1.1.1 still the same problem. I'am i doing
something wrong?

I'm using OpenShot 1.1.3.
I can confirm this issue.

[Vanessa Lee (vanessax)]

I just wanted to add that this occurs intermittently with clips too, sometimes the effects are also not applied to the very first frame of the clip. I can not reproduce it consistently. The workaround is to add another track and move the clip on to that and it seems to fix it. I use Openshot 1.1.3

[mde (mde-micahelliott)]

I'm seeing this too -- with both transitions and fade-ins/outs. The workaround works though: I just created a new track and dragged the problematic clips to it.

I'm really now sure how OS got into this state. I dragged one clip around and then at least one (likely more) track's worth of clips started behaving badly. Sorry that I can't even say if it was on new edits, or if the existing transitions just went wacky at that point.

[Darren Conway (darren-conway)]

I have the bug to. I am using Ubuntu 11.04 and the latest Ubuntu Openshot package.
I have tried the work arounds.

I placed a clip on a track (the only clip on that track) and added a fast end fade. The clip is an image (Title screen). The clip did not overlap any other clip on other tracks. When the clip played, it faded, then the image flashed at the end of the clip. After the flash, the display went black (as expected because of the gap to the next clip on another track). This demonstrates that the flash can occur without interacting with an abutted clip.

I have the same problem with transitions. I get a flash at the end of the clips.

[drwho (drwho-infidigm)]

I too have the "single frame flashing bug" at the beginning of transitions. I've tried making the transition longer by starting the transition sooner thinking that it just wasn't positioned right. I added up to 2 seconds as an experiment, the flash continues to stay at the beginning of transition even though the next video doesn't start for another second or two. It seams random. All the types of transitions that I use are affected, circle in to out, Big spiral, clock left to right. The flashing doesn't seam to happen in the first 20-30 min of the video. I have about 80 clips in a 2 hour video. I haven't tried the "move clips to the new track" workaround.

My input video is at 29.97 fps, 1080p AVCHD mpeg4, 24Mbps. Audio is AC3 256 kbps. It comes from a Canon Vixia hf20.

I've tried Openshot on Ubuntu 10.10, 11.10 and 12.04 beta. Flashing bug exists on all. I've recreated the project multiple times. I've tried converting the video to raw format with avconv, then creating a new project using raw video. Bug still appears. Also tried from mpeg 2.
