Note that a conversion to flac format does not alter the audio data in any way, so you cannot get lossless audio from a lossy source by converting it to flac.

Thanks for your help GRC and roann.
The files are
Streams
Video: 00:16:17.520, 25.000 fps interlaced, 1920x1080x12, AVC
Audio 1: 00:16:17.520, 48,000 Hz, 5.1 Surround (stereo downmix), Dolby AC-3
Audio 2: 00:16:17.520, 48,000 Hz, 5.1 Surround, Dolby AC-3
So, to make this ready for a trade i just need to encode it to flac? And it will always be lossy because it came from AC-3?
Just out of curiosity, would a Flac upload of this concert be allowed here?
Thanks again.
