Hi Members,
I have reported to CL an issue with Magic Motion - zooming into a still image and the clarity of high resolution images being lost. In my test I used an image from a Canon 7D which formed part of a panoramic stitched image. You just need to use an image from a still camera. Using Windows Preview I zoomed into my image so that a far off cluster of houses and a bay became visible and with very distinct clear features. Using MM I zoomed into the same area on the image. MM presented me with a complete blur and no clarity whatsoever, the resulting zoom was unusable in a video.

The test I'd like members to do is to compare Magic Motion zoom to Windows Preview of the same image - zoom in very close on both and produce a video, to see what the resolution looks like. I chose 1080p.

I'd like members feedback and opinion on what is being presented to them.

You'll note this is Item 217 - I've reported the issue and would like a number of second opinions to confirm my findings for CL.

Many thanks to those who take part in this Magic Motion test.

Dafydd

OK......

After I figured out what you was talking about..... I have similar outcome as you but not as bad. I used a 3264x2448 image, zoomed in a long way, then produced it to 1080p wmv.

My magic motion preview window was similar as yours with the fuzzy but not near as bad, I assume you would get fuzzy after zooming in far enough anyway. However my rendered wmv had far more clarity than any of my HD preview in the edit window. I have attached a screen capture of the magic motion preview windows and my rendered wmv file. The wmv is 24 megs for 20 seconds of video.....

Hi Dafydd

I used an image from my Canon 550D (3791x2525) and use MM in PD9 to zoom and then produced it using MPEG2 1080 HD and the results were poor.

I then did exactly the same in PD8 and the results were not as good as the zoom in Windows BUT much, much better than PD9.

Hope this helps.

Happing editing

I find that it does become fuzzy, but in my case I zoomed to about twice the resolution of the photo, so it was not as bad as I expected.

I did find that over several tries, none would play roughly the last 1/2 second of the produced movie. I produced them to 15 second files and every one stopped playing around 14 1/2 seconds. I don't think it is related to magic motion. It was just more noticeable while zooming. __________________________________

Thank you everyone.

I used a stitched panoramic image made up of 20 images. I wanted to zoom in and then out with a pan etc

Panoramic stitched image = 22420 x 4441
20 images were = 3145 x 4718
Hugin used
Hand held I believe. From a mountain on an island (Skye).

See attached image.

Thanks once again to everyone checking this issue out. I'm pretty keen to be able to do what I want with Magic Motion and stitched images.

Hi James,
Could you elaborate a bit more on your observation regarding video length please?

I think that you may have found a bug which needs to be confirmed.

*****************
Hi Neil,
Could you "whack in" a couple of screenshots of the two PD's for comparison please. Interesting results.

*****************

Hi Bubba,
Thank you for having a go at this issue. When zooming into an image you have to be aware to stay within the pixel parameters of the video you're outputting to or a blurr may result. I went under 1920x1080 (1280x720 would be ok) in my test and as can be seen, the blur was dreadful, in the original it wasn't so bad.

*****************

If anybody else can have a go and use a stitched image or two, that would be great.

Many thanks everyone.

Dafydd

I used an original 3872x2176 image.

I used Windows Preview to zoom in until the image started to pixelate.

Placed image in timeline PD 2930.
Applied MM and zoomed to the same magnification as above
Produced as a 10 sec video AVCHD, No Hardware encoding, 1080 standard profile

Image snaps attached.

My observation is that the larger the original image & the more extreme the zoom/crop, the LESS WELL PD9 handles it. The most extreme degradation is on panorama shots (see Zoom_Test5) which, by the way, could NOT be imported into PRE!

I used 5 high res images to test, 4 of them downloaded from photography sites & one from my Canon 500D. In each case I followed a similar procedure to Adrian (above). The images attached show a comparison between the last frame of the produced AVC H.264 (1920X1080) file & the same part of the image zoomed in Windows Photo Viewer.

Zoom_Test1
Image Resolution: 10000x5626
Zoom to: 3242x1850
Zoom_Test2
Image Resolution: 4892x2753 (Canon 7D)
Zoom to: 1467X840
Zoom_Test3
Image Resolution: 8000X4494
Zoom to: 1348X758
Zoom_Test4
Image Resolution: 4652X3168 (Canon 500D)
Zoom to: 876X597
Zoom_Test5
Image Resolution: 18000X2286
Zoom to: 1529X860

Could you elaborate a bit more on your observation regarding video length please?

I think that you may have found a bug which needs to be confirmed.

It now appears that it is a glitch in the players. I tried it on a few different media players and they all cut the movie off before the slider reaches the end of the video. However, when I time the video it is the correct length. The video I have attached does a short zoom using the Magic Motion. Then the image return to original size for exactly one second. VLC Player and Windows Media Player both showed it to stop before the slider reached the end. DivX Player seemed to play the whole thing, but showed the length as 9 seconds instead of 10. When I used Nero, which stays open after the video is finished, it was easier to tell that it did in fact play the whole video. I have attached a sample if anyone wants to verify that it is the player and not PD.

Hi everyone,
Tony, you have reached the same conclusion I have. Large panorama stitched images used in Magic Motion have a focus/blur failure when zoomed in.

Thank you everyone for taking the time to test out Magic Motion.

James:
The jump may be caused by the position of the keyframe and the slider, that's what it appears to be. Can you take a snap of the Motion Designer please. We also need to move this to a new topic.

Thank you once again for participating.

Hi,
I should have posted an answer to item 217.
CyberLink "When placing a panoramic still image into timeline (6000x1200), PDR regards whole image as a video clip then to do the zoom in action. The full HD video maximum resolution will be up to 1920 x 1080. Therefore, it cannot be zoom in to an image and still keep a good quality. The higher the original image resolution, the less quality. For example, the 6000 x 1200 image turn into 1920 x 1080, the resolution will be downgraded so the quality might not so good. This concept of zoom in video and image is quite different."

I should think WPanorama is the solution but I have yet to try it out.
