pan an image larger than the video dimensions ?

[mangurian]

Is there a way to use a very large image (say 6000x4000) and then make a video which pans around in it ?

Thanks,

[asik1]

yes, place it as overlay and set it to original size.

You might like to also investigate the powerful tool known as "Custom Motion" - move what you want - where you want at almost any zoom level

Will do. Thanks,

I do panning all the time. Video track, overlay track doesn't make any difference.

Add to a track then use Custom Motion or Pan & Zoom to set the vertical size (can be less then frame height), set start point (off screen, at edge or in between) then set the end point (ditto relative position).

You can add zoom out as well - pan across the zoom out to shrink size and fit frame width.

You can do the same for a vertical pan (I've done this a few times).

I've tried this but it doesn't appear to address the issue of VS ignoring the photo’s resolution on a panoramic image (see viewtopic.php?f=1&t=60291&hilit=panoramic).

I have a panoramic photograph (8504x2160) and use the ‘pan& zoom’ option to zoom in and avoid any black border (zoom ratio = 223%), and the pan feature to move across the panoramic photo. The following image shows that the rendered output (3840x2160) looks terrible in VS when Pan & Zoom is used.

If anyone knows how to use the ‘pan& zoom’ option on a panoramic photo and avoid any black border, I'd like to know how.

Thanks,

tletter, did you start with "set it to original size" ?

Hi tletter

Pan and Zoom different results to settings

When you use P&Z does the view set within P& Z show the same size when returning to the timelines
I have just run a test on a pana image 8192 x 1856
I eventually chose Static so I was viewing like for like, easier to compare the sizes
The effect within P& Z was say 50% zoom, yet on the timeline showed 75% (just a guess at those sizes.)
But there was a marked difference in sizes set in P& Z compared to the timelines preview screen.
Obviously zooming in too far is gonna affect the quality, and my image looks terrible.

Using Customise Motion seems to do a better job, that is the sizes I set set is what I get.?

Ok i think i found the culprit in selecting Original size, that effectively zooms in, then we apply P&Z which zooms further,
Pity it does not show on P& Z panel

tletter, did you start with "set it to original size" ?

Yes I've tried that and other things I can think of to no effect. If you want to see the issue, I've uploaded a panoramic photograph (8504x2160) that I'm trying to pan across and render it as a 3840x2160 video (https://www.dropbox.com/s/mshdmpl0eiokcx5/8504x2160.jpg).

When you use P&Z does the view set within P& Z show the same size when returning to the timelines

I'm not understanding. In any event, I'm simply using the zoom option to zoom into the 2160 pixel size of the photo to avoid black borders then pan across the whole 8504 pixel wide photo to produce a usable 3840x2160 video. However, this is not the case as output is horrible.

Obviously zooming in too far is gonna affect the quality

Yes but zooming in to a 2160 pixel size is not zooming in too far, rather it is zooming in to the photo's native height. However, if I crop the 8504x2160 panoramic photograph to 3840x2160, then the rendered 3840x2160 video is good quality but it's no longer a panoramic photograph. Hence the conclusion is that VS has a bug that ignores the actual height of the source photograph thus preventing the use of panoramic photographs at full resolution using either custom motion or P&Z. I've tried every version of VS from X6 to 2018 and result is the same horrible output.

Hi

It is not just zooming in thats the problem
Project Properties set to 1920 x 1080 create a background of that size. When we add an image it can only be displayed using those sizes.
So adding an image larger is gonna have pixels removed, and that’s the problem.
As we zoom in we are zooming to 1920 x 1080, video studio should read the actual image file and refresh for each zoom, then we would be using the image quality. That does not happen

That is why your largest image looks worse than the smaller one, because more pixels have been removed to get to 1920 x 1080
If you set the Project Properties to use 4K sizes that would retain a better quality, provided you render to 4K.
Tletter you have discussed this in earlier posts, afaik nothing has changed to improve VS.

I have downloaded your image, nice image by the way.
Will give it a test to see what quality I can produce.

lata, I'm not understanding where the FHD dimensions that you refer to come from, since as previously stated, I'm rendering a 8504x2160 panoramic photograph as a 3840x2160 video, i.e. to 4K. That is why I'm working with a 2160p panoramic photograph and have no interest in rendering as FHD.

Thank you Tletter for the fine image.
I agree P&Z is totally crap.
Few weeks ago we had slimier Q with a guy who needed to pan over a large music score sheet , Trevor could locate it better than me.

Over the years I did use images larger than FHD ( but not so large as this one) and PZ them, I don't recall getting such crap results on my VS19.2 as with this image.

Ok

Thanks for the update, I understand now

Did you download the samples from my one drive, are they any better quality from what you are creating?

Can you attach your VSP so I can work with your actual settings.

I used 2560 x 1440 as that was the only settings that allowed 60P to be set for Project Properties

I did try 100fps but that froze the program when applying the zoom / Customise Motion???

Hi Asik

That image was 28352 x 2657px, a music score, much longer than tletters image.
The only solution there was to create separate images, effectively splitting the original into 12 images.

If I find the post I will update
