Associate Minimovies PRO 7 months ago Hi. I'm uploading WMV files to my Vimeo Pro account. The WMVs play back fine on all PC's and mac's when NOT played through Vimeo. However, when uploaded to Vimeo, the first half a second of audio is a very loud hiss. Everything is fine after that. This only happens with WMV files. As the file plays fine on the local machines NOT in Vimeo, I don't know what could be happening once it's uploaded. I've tried a variety of render settings but WMV persists to be a problem; uploading other file types of the same video are ok. Do you know why this would be happening please? The audio codec is WM Audio, Stereo, 16bit, 44100 sample rate. Video codec is VC-1. Thanks.
