Hi
I want to edit an mp4 video file I already have to be narrated in my language , I know I can record the video which is playing on windows media player using camtasia , but what if I recorded the video and want to add up an audio file to it , how I can add that ? How can I record an audio file with camtasia and then attach it to a previously recorded video?

Hey Ibrahim,

You should be able to import your audio file to Camtasia, than drag it to the timeline without issue, assuming it's a commonly used file format.

Let me know if you have any other questions!

with your MP4 on timeline, use Voice Narration to add new narration directly to the project

Logan thanks a million ... I think best thing to do is to make timely voice recording , then add that as you said to the timeline .... the big problem now is how to make the voice mp3 file coincide or synchronize with silent video mp4 file ......any idea ?

with [silent] MP4 on timeline, play it and view in canvas

do this over short segments, where you want to add specific narration

practice saying narration [as MP4 plays] to get the timing down

when it feels right, do the voice narration

the new voice narration will go on timeline at playhead start point, it will often indicate a slight pause before audio waveform shows

slide the new audio clip to left to align start of waveform with start of narration point

again, do this in short chunks; with a little practice, you'll get great results

be sure and silence speakers when doing voice narration

Thanks kayakman ..but I think that would be very time consuming and hard because I will be recording a video which is playing via WM Player continuously , despite I have the translated scripts written in a minute by minute way ... I have 25 hours of videos need to be converted to my language ...I think the best way is to use an audio recorder and try to make my recording exactly matching the silence videos on camtasia ...that way I wont have to pause video when ever i need to stop recording if I use camtasia for both audio and video ....I wish camtasia have a separate audio recorder for such a proplem I have ...

actually, I was suggesting you record the audio after the videos are captured; Voice Narration lets you watch the video in the canvas while doing your narrations

I find it easier to match audio to existing video than I do to match video captures to existing audio; you can always use clip speed adjustments to get a segment of video to match an audio segment, but you can't really do the opposite without gettin g distorted sounding audio

however, maybe experiment some and take what ever approach works best for you

Thanks kayakman ..I did not use Voice Narration before ... now I have seen how it works i will for sure take your advice ... one thing I did not understand ... what you mean by saying : " you can always use clip speed adjustments to get a segment of video to match an audio segment, but you can't really do the opposite without gettin g distorted sounding audio ... Can I tweak or adjust the video length for each clip in the video track in the in the time line to match the audio track periods in the time line ?

yes

you can apply clip speed adjustments to separate clips or sections of separate clips;

I find it best to edit projects in short, manageable, sections; I use the Library to hold the sections

if a video section is too short for the necessary audio, lengthen it by slowing it down [set clip speed to less than100%;]; if too long, make it play faster [set clip speed to greater than 100%]; it's easy to do once you get the hang of it

have you had a chance to watch these tutorials? they can really help ...
