I have an .avi file in which the time stamp is in a very delicate font. I would like to change it to a bolder font. Is that possible? Thanks! ben

How did you render the timestamps on the AVI? Worst case, re-encode from your original, rendering with a larger font.

The time stamp was placed on the original file by a dvr in a pripriotory ? codec labeled .psf. I cannot find any program that will play this except the one from the dvr seller. I have copied this with total recorder off the screen to an .avi file. I would guess that it would be impossible to do anything with the font in this copy! It is also possible to obtain an .asf from the dvr. This does not have a time stamp. Is there any possiblity that one is present that could be render to this file? If you have any other ideas, I would appreciate your help. Thanks! Ben

Hey did u get the solution or still looking for it?

I am still looking. Any help would be aprreciated. Ben

Avisynth + . Just set the starting offset manually, then set size, color, position etc.

As I thought, the TC is "burnt in". It can be "delogoed" then re-added.

The link above shows the frame from the .psf file copied with total recorder -That date/stamp is not masked and shows background video - , the same date/stamp with a smaller date/stamp overlayed at the bottom of the frame on a mask, and the original date/stamp that I am trying to replicate. The correct date/stamp has a different date format and a 24 hour time format. I am mainly at this time trying to make the white font of the middle frame as bright as that of the bottom frame. I would like to also try to match the date and time stamps but that may or may not be necessary. I have not had enough time to try your code above will respond when I do. Thanks!@ Ben

These are the three frames discussed above. Ben

Perhaps kernel morphological operation http://stackoverflow.com/questions/5154282/dilate-erode-modify-kernel-option on enlarged video - later resized down (or crop selected area, pointresize, kernel op, bicubic/lanczos downresize).
