i want to create watermarked videos with mp3 as audio. but it does not work. watermark master re-encodes the videos without sound. i tried different video formats as input. it's very important for me to find out whats the problem. PLEASE help me.
no thats not the problem. i know that the videos must re-compressed.
example: i have a video compressed with mpeg4-v2 and mp3 audio. i want to add a watermark to this video and want to re-compress it with mpeg4-v2 and mp3 audio. but the re-compressed video have no audio in it. it ried using the option "try using source codec" too but these videos have no audio too. other audio codecs like ac-3 are working but i want mp3. so what could be the reason of the problem?
