When I try to convert an avi to mp4 or m4v file wondershare just sets at "waiting" and nothing ever happens. It seems to work fine to convert mkv to mp4 or m4v. Any suggestions?
Will the watermark dissappear if you pay for wondershare?
When I convert an AVI to MP4 it cuts the movie in half. The AVI is 1hour: 32mins but the MP4 output is only 28mins long ?
Hi, agleek, maybe you have missed something there. If you convert a 2gb file to 7mb file, the quality will be greatly reduced, Maybe you can try it again, choose iPad 4, iPad mini, iPad 2, or whatever you get as the output directly. It will play greatly on your device. If still didn't work, maybe there is some problem with your original file. In this case, you can refer your file information to our support team to fix the problem asap. Best regards,
I recently downloaded the conversion tool on my PC, and am trying to convert a 2gb avi over to .mp4 for iPad. The output is not what I was expecting; while the file size is great (7mb) the quality is not good at all. Perhaps I am missing something in my settings? I have the quality set to the highest setting, but the output is blurred, grainy and there is terrible motion blur. Any help would be appreciated!
