I bought the software and followed above steps importing a MP4 video to remove the sound. My problem is that when I saved the result as a MP4 it was 4X larger. I tweaked the parameters until it was only about 20% larger than the original. However the resolution is noticeably worse. I would like to keep the quality of the video and keep the size the same. How can I do that? I include a picture of the properties. Original right Result Left. Please work me though this issue.
Hi,vmars316. After importing the audio to the program, then you need to drag it to the music track. Move the audio to sync it with the video, if necessary. Then you can click the Export button(For Windows version) or the Output button(For Mac version) to generate the final result. In the output interface, you can adjust the video parameters to get an acceptable file size.
In step 2 above: "Tips: If you're going to add audio to MP4 video at the same time, you can import the audio file to the media library and drag it to the timeline panel. Then click Create to generate the new file." Where in the world is the CREATE(button or whatever) to add an AUDIO into video . ALSO: in step 3 above, the original mp4 input is 17mb , but the "Export your MP4 video without original audio" is a whopping 47mb . That is totally unaccecptable . Thanks for your Help..vm
