how to use melt to do video overlay? It's just like a PiP(picture in picture) - overlay

I want to use melt.exe (command line video editor) to do something with video overlay. It's like overlay a video on the other that I can control the size and position of the video which will be placed. I have done this with shotcut and view the xml it generates.
But I want to know how can I do this with melt command script. Or if I have known all the information about video overlay such as in/out points, size, position, and how to create a xxx.mlt(xml) file according to these info?
I got the three videos overlaied to generate one like this :
final effect
I use shotcut to do this and I get a .mlt file. sorry I don't know how to upload the xml file or maybe it can't be.
So I want to know how to do the same thing with melt.exe?

azure media text watermark on video set on right side corner c#

Using Azure media Service we can Create an overlay an image onto an existing video which I had achieved using your documentation. But can we create an overlay(Watermark) a text onto an existing video and second.
How can we set watermark text/image on right side corner. I went through all documentation but haven't get any solution on overlay a text onto video.
Any help would be appreciated.
I presume that the text that you want to overlay will change from one video to another. If that's not the case, you can create a PNG/BMP image with the text and then use the 'static' image overlay option via the Standard Encoder.
If you indeed need 'dynamic' text overlays, then you will need to use the Premium Encoder. Please contact us via mepd#microsoft.com, and we'll provide instructions on how to get access to the Workflow Designer tool, which you will need in order to make use of the Premium Encoder. There is an example of using the Premium Encoder for such text overlays documented here.

Project to show the path of moving object

I have a project in which I have to show the path of a moving object from a video in a single image. How should I go about with this one as I am new to image processing and Matlab.
The easiest way would be to load the video as individual images. Afterwards, after segmentation or whatever needs to be done for your specific problem, you have to save the position of the object in each image.
Once you have saved all positions in a matrix you will be able to record and visualize a trajectory.

Text overlapping in video processing Matlab

I'm a fresher to matlab, and I'm trying to extract text from video using ocr methods. My problem is, there is same text appearing in consecutive frames, and sometimes when camera is panning new parts of already extracted text will reveal and I have to add those to already extracted text. Both makes it difficult to store a text only once if it appear in video once while playing. Text usually are name boards or road side boards having text which are captured in the video. How to solve this problem?

Is it possible to overlay dynamic boxes over a live video feed in matlab?

I'm doing an object recognition project and would like to actively see objects being recognized in a video feed. This requires the object be boxed around in the live feed. The box would automatically adjust in size depending on the size of the object.
Is this possible in matlab?
Assuming you can do it for an image, just do it for every image and you have done it for the video.
If this is too slow, you may only want to calculate the box for every nth image.
In case you want a more detailed answer, please show where you get stuck.

set unique value for size of mp4

What I want to do is to have my mp4 always display the same size as if the user double-clicked on the mp4 while it was playing (i.e., with the black bars top and bottom), rather than opening up full screen.
How can I display the mp4 as described to begin with and not allow the user to change it?
My best guess is to change the frame size, but I am not certain this is the optimum approach.
