No Pan and Zoom Icon

[wsmyth]

Thanks folks. No time to look at this until 9/8. I will be in touch.

Hi guys. Thanks so much for all your help. It all works now except the pan does not move in a straight line. There seems to be no way to fix it unless I put in intermediary keyframes. I have the gridlines on there as you can see, but it still moves in odd ways. At 26:12, it pans to 27:05, but it follows a curve to the right first and then goes to the left to arrive at next keyframe. Any additional comments on the straight line issue are much appreciated.

I used three VSP files, and I have included them here. I added the TXT extension so that they could be attached. You should be able to use the same base file MP4 file. The first does the Mercalli and creates the a file. The second does a Customize Motion and Trim and creates the b file. The third then does the P&Z to create the final x file.

I was a little confused with the zoom between keyframes, I was copy and pasting the keyframes positions yet the zoom appeared to change, then I realised you are compensating for the actual cameras zoom.

Keyframe 4 I think was a little high, although could have been 5 and 6
I tweaked then, sensitive and difficult to get it right, but now I believe the pan goes directly left and not looping right.
Have not had time to view the other VSP’s

Thanks Lata

I have typed my reply in here several times, and i keep accidentally X'ing the window (as I close the VS window, it clicks again, and I close this window). I am tired of typing it in.

You are either using a different version of VS, or there is an option I am not seeing. I will have to investigate other message board entries on straight pans.

Note that all of your lines are straight (not just the one we have been talking about that moves to the right). All of mine have some sort of weird curve that the system puts in there when it sees the pan moving from place to place.

I have done so much investigation, and I can tell you so much more, but I keep typing it in and loosing it. It appears that there was a bug in X10, and it has been fixed in a later version. I just looked above and I see that your VSP was "Created using VS X10". This does not make sense to me.

"Tweaking" he crosshairs does noting to change the curves on the pans.

I tend to type into word, then copy and past here

I am using X10 to test Pan and Zoom, although I had better results using Customise Motion.

It does appear that you are not only using P&Z to navigate across the stage but also to stabilise the video, and that makes it quite complex.
It would be good if the keyboard arrow keys would nudge the crosshair position but no we have to rely on the mouse to drag which I find difficult to be accurate.

Your last attached VSP does show the pan going right then turning left to the keyframe, I managed to tweak the keyframe height, took a lot of attempts but eventually did manage a straight line.
As I said not sure which was the culprit 3, 4 or 5.

As a thought I am not sure what affect Mercalli and Pan & Zoom has and whether there is any conflict here.
I would apply Mercalli then render the clip to a new file to fix Mercalli in stone, then apply P&Z, probably being a little over cautious.

Mr Lata… I cannot thank you more for taking the time to respond to my messages. Thanks for the tip on writing the message in Word. I had a Firefox extension that saved the text to the clipboard every ten seconds or so. But the old extensions are not working in the new Firefox.

So you know, I did try Customize Motion. I cannot figure it out. Also so you know, I did make three VSP files. All are shown in my post on 9/23/21 at 9:10 PM.

First, I did the Mercalli, rendering a file with a appended. Second, I ran Customize Motion to straighten the video. Straightening is the only thing that I can figure out in that feature. This rendered a file with b appended.

This is what I used the third VSP on. It only does the P&Z. It refuses to move in a straight line. As far as I can tell, it has nothing to do with tweaking the crosshairs.

I noticed that you used my third VSP on the original file. I do not think this has a bearing on our discussion. Your video pans in a straight line. Mine has the curves. Please note that this is true for all the pans, not just the pan that we have been talking about where the pan moves to the right a bit before moving to the left.

One of the other threads in the Forum discusses this problem. You contributed to it.

It shows the curved lines instead of straight lines. It shows that one must add additional keyframes to prevent the curved line. You offer some ways to add these keyframes. Am I reading this correctly? Is this how you fixed my VSP? I do not see any additional keyframes.

Another thread that I do not see a contribution by you shows that there is an option “Cylinder” in Moving Path, which must have formerly been on the P&Z options screen. I could not find this option. The post is from 2008, so I guess the option was removed. I cannot imagine why.

To me, it appears that I either must live with it or add a bunch of additional keyframes. Trust me, tweaking the crosshairs on the keyframes does not fix my problem.

I cannot understand why your curve lines cannot be straightened, nor why you are seeing those on all pan lines.
I only tweaked the three keyframes, I think 3 , 4 and 5

You should persevere with Customise Motion, works similar to P& Z in that we use key frames.
I did provide a CM sample, although I did cut the video into individual clips and applied CM to each rather than applying to the complete clip.
I just found that easier as I have only a few keyframes per clip

I'll do another effect using Customise Motion to the full video clip, just means a lot of keyframes.

Needs a bit more work but should give a good idea of what can be achieved.

If the curving loop in pan-zoom is still the issue, did you read my previous post?

I fixed it but it was easier than what you described. For what ever reason that key point location moved. All I did was grab the "+" path marker at the key point and drag-drop onto the proper "+" marker on the left side.

[wsmyth]

I got it to work, mostly, but not without a ton of tweaking those crosshairs.

There is no excuse for this. Either give us an option to move the pan in a straight line or not.

Thanks Trevor and gewb.

Also I looked at your Customize Motion Trevor. The tutorials on this feature do not show how to do this at all. The blue line and everything. Can you recommend a tutorial I can view to see how you are doing this?

Setting Customise Motion uses Keyframes in the same way that P&Z does
We can add a Keyframe then resize by dragging the yellow handles or reposition by dragging the frame.
Using CM we can also position more accurately using the X Y Position settings and Size again using the X Y
Those two options being the basic Pan & Zoom options.

Other options such as opacity will allow us to fade in / out
My last VSP has the first keyframe set to “0” opacity causing a fade in to K2, and again for the last keyframe K22 to K 23 fades out.

Oh just noticed I have 2 keyframes set on the second keyframe. ( there may be another at K12 – K13)

You are best navigating through the keyframes using the navigation options immediately below the preview screen, that avoids moving the key when selecting using the mouse
“Go to next Keyframe” will identify that duplicate keyframe.
Open my VSP and view Customise Motion
Select any Keyframe, view the Position and Size settings, tweak the settings if you need to.

Tutorials
There are a few about, but Customise Motion does a lot more than just Zoom and Pan
Certainly one of the best tools provided by the program, you should take time to master this.

Reflecting on your original video recording, there are sections that shake a little that needs Mercalli stabilisation.
I would apply Mercalli, then Share – Same as first Clip to render a new stable video
