I know this has been asked a few times here and the information given was excellent!
Basically, I have a video clip where I want to use an overlay to hide a car license plate.
I am already doing this using the: Simple Shape Filter, Mosaic, Filter Apply
method which is absolutely fine for when the license is large.
However, I have recorded video in 4k and there is a sequence where the licence is still visible using the mosaic method. I have tried to look at things frame by frame but it is becoming a little difficult as I think the mosaic isnât blocking the information since itâs too small.
Currently I have 2 questions:
is there a way to zoom into the video in the Project window?
I donât mean to use a filter to zoom the video but instead, zooming the âpreviewâ similar to that used in still photography in order to edit details?
but that requires a âcolor clipâ⌠I didnât really understand that? Does it mean that I need to create an image with the same dimensions with solid fill color as the video and overlay that onto the image using a second track?
I wonder if Iâm going about this the right way? Currently I have lots of key frames to try to mask the license plate as the camera movement isnât exactly in one direction and continuous and Iâm still seeing parts of the license after exportingâŚ
In some places Iâm having to add keyframes at ever 01 tenth of a second basically.
Itâs not too much of a problem, just lots of âextraâ work and a little laborious but achievable still.
Strange thing with the mosaic Width and Height options⌠they keep jumping to different values after I change them?
If I set them to say 0.3% each then save and re-click on the filter they will be at something like 0.3 and 0.1 or so⌠is this normal behavior or am I doing something wrong?
That doesnât sound like normal behavior. And I wasnât able to reproduce it.
Can you list the exact steps that leads to that problem?
You just mention "save and re-click on the filter ". I did that, but the values stays the same in my project.
I think there are two issues which are a bit oddâŚ
So the first one is if I click on the Mosaic filter with the âkeyframesâ parameter enabled for both height and width and type in a value, say 0.3 in the height portion.
Automatically the value will change to something 3.4%?? The numbers seem to be random.
It might be down to where I click though I am clicking on the text so it shouldnât adjust the level bar at allâŚ
It might be something to do with the âkeyframesâ being used before and after, Iâm not sure.
The second issue is as described above.
I change the value from say 0.1%/0.1% to 0.3%/0.3% and save the project.
When I go to the same keyframe again, it displays something 0.2%/0.3% or 0.1%/0.3%.
Iâm using version 24.04 on Arch Linux (from repositories) with Qt version 6.7.0
