Compared to the original version of the image which looks OK, when I use zoom out/in or pan from sides the final video result looks blurry.
Even thought I have set the export value to H.264 High Profile and in the codec I have increased the value to 75% still the exactly the same results after exporting the video.
Is there any way to preserve the quality of the image when doing zoom or pan?
I am using Shotcut 22.11.25
Video mode 720p - 29.97fps
I tried even with an image twice as big of the 720p - click the link to see the result.
What version of Shotcut do you use?
What is the Video Mode of your project? (Example: 1980x1080, 30fps)
What are the original sizes of you images?
Can you share an example of an exported slideshow that shows that blurring? (use stock images if you don’t want to use your own).
A screen capture of your entire Shotcut window might help also.
Do you see that blur problem also before you export your project? Or only after exporting?
If you see it before exporting, increasing the quality in the export settings won’t remove blur.
That depends on how much zoom you apply to the images. If you zoom them to 110% for example, it shouldn’t be much of a problem. But you use more zoom, like 150%, 200% or more, you will start to see some blur.
This is an important question. If the preview looks good, but the export is blurry, then you may need to tune your export parameters. But if the preview also looks blurry, then the blur is being added by the project filters or processing.
And there is only one SPR filter applied to each image, and not two? I’ve seen this problem before on images when there is a second SPR filter, but not just one.
The SPR filter performs interpolation - which will always cause some amount of blurring. But it can be affected by the interpolation mode. The interpolation can be changed for the preview player in the player menu. The default is “bilinear” in order to provide the best performance. But you can change it to higher interpolation to have better quality in the preview.
