Nobody can tell you anything without proper system info or other technical details, including some sensible explanation of your problem. Sorry, but your post so far is just useless mumbling.
As I stated, it might not be clear,, I will try again...
Iam trying to add images to a video which is already in mp4 format. I know adding an image to existing video is simple. However I want the new content or image to appear after deleting one of the images in the video. I hope its clear till here...
I would imagine this could have been easy if I could see individual files within the video so that I can delete necessary file and add a new one. Since I dont have access to the old files, how will I had it?
I can explain again, if this is not clear..
sorry about mistyping ....the last sentence meant :
I would imagine this could have been easy if I could see individual files within the video so that I can delete unnecessary file and add a new one. Since I dont have access to the old files, how will I add it?
An MP4 has no reference or relation to how it was created. It's like a JPEG instead of a layered Photoshop file. There is no way to access anything about the assets that were used to create it.
So...no. What you're asking for can't be done.
Now, you can insert things into videos, it just requires rotoscoping.
It is possible you're using the wrong application. From your description, you may be better off using Premiere Pro.
