Hi Liza, I have an MP4 file I am trying to upload to wondershare video editor, but the audio is off once its there. Have you ever come across this? I found this thead as I was trying to google this. Thanks! Andrea
Hi there, it needs to re-encode whole trimming files but with little quality loss by using this program. You can download the software to have a try.
Hi, I'm just wondering if this can trim single files without having to perform a re-encode, the way that VirtualDub and Video ReDo can on the PC? I have a number of long files I want to split but I don't want to re-encode the whole video on save which loses quality. I want something which simply re-encodes the few frames between I-Frames and the cuts which first off is quicker, but secondly loses effectively no quality overall.
