Hello
I couldn't find the thread which covers these topics so I apologies. I got the same bluray movie that has been converted and was thinking which is the best one to keep.
To the experts if you can please tell me.
1st movie :
Video : 1280*720 / 5779 | 4980 | 6035 kbps
Audio : English / AC3 5.1 | 640 kbps
2nd movie :
Video.....: AVC x264 1280x720 2200kbps 23.976fs
Audio.....: English 384kbps 48khZ 6channel AAC(LC)
3rd movie :
Video #0 : AVC at 1 812 Kbps
Aspect : 1904 x 1072 (1.776) at 23.976 fps
Audio #0 : AAC at 384 Kbps
Infos : 6 channels, 48.0 KHz
Audio #1 : AAC at 124 Kbps
Infos : 2 channels, 48.0 KHz
Thank you very much.
The first one has the highest bitrate and best sound.
Hello
Thanks for the reply on the post about which video/audio codec is best.
I was wondering isn't their a section where users could post about video codecs ? I've just received 500 + movies & have multiply copies and don't know which are the best. I can identify from the source 1080p, 720p but wanted more knowledge on it.
Anyways thanks
Well for a start you need to use a consistent tool to look at the files, your three examples above are all formatted differently and show slightly different info.
mediainfo is a well known and respected tool for investigating files. An example output:

Really if you want high quality video these days you are looking for
* h264 or VC1 video codec
* reasonable bitrate
* minimum 720p resolution
Also pay attention to the audio - a perfect video rip with a lousy stereo soundtrack might be a worse experience than slightly lower quality video with a great hifi surround audio track.
The ultimate test is how it looks to you.
