About DASH video : Why can't I hear any sound from it?
Well, of course, DASH video is, as stated by it's name, contain only video stream, there's no audio track in it! You should also download DASH audio format and play it together with DASH video.
How can you played it together/at the same time? My blog has the answer: Play DASH video and DASH audio at the same time using VLC
How can I convert the video into specific video/audio format?
After you click "check" on your video URL, you have to click the "Advanced Conversion Options >>", vRank will show you the supported target formats.
We currently support conversion into: (for audio) mp3, ogg, wav, opus AND (for video) mp4, webm, avi, 3gp, mkv.
Why does vRank so slow connecting/grabbing video from certain sites?
It's because vRank doesn't have all good connections to all supported sites. Some of the "slow" host: dailymotion, vbox7, and few others.
Is this service free?
Yes, vRank is absolutly free.
