I installed NXT7 one month ago on my windows desktop. 64 bit, windowns 10, newest updates.
Using videowave I've historically been able to ad mp3's to still images at 60 min duration for youtube.
All of a sudden, the audio . at 30 min mark (approx) starts phasing, flanging, and distorts. It progressively worsens.
I've tried the audio on sound fx, music, and internal track. same result.
ij've tried exporting to ipad 720, mpeg 720, and achvd 720x480. same result.
I redonloaded mp3s from source on web, using diff browser. checked mp3s using WMPlayer. they are fine. no distortion.
I switched from render using hardware to software. same results.
Is it the audio filter?
