I have done very little uploading to YT over the years and so am looking for some opinions on what settings would ensure I get the maximum quality from an AVCHD 1920x1080 50P H.264 MPEG4 file from my Sony and Panasonic cameras.
I normally export my files to the AVCHD Transport Stream 1920x1080 50P HQ template which results in 26-28Mbps file with AC-3 Stereo @ 384kbps which keeps the original quality for playback on my TV.
Taking into consideration the YT recommendations here :https://support.google.com/youtube/answer/1722171 I wonder about what sort of quality I would get using their rather low recommended bitrate of 12Mbps for 1920x1080 50P ?
How much more could I increase the bitrate (or in fact upload using my normal export template at 26Mbps) and actually expect to see the improvement in quality if I streamed YT to my 50" HD TV? My file is only 8 minutes long BTW so the length of time to upload should not matter to me.
Would the picture and sound be any different keeping the AVCHD .mts and 384kbps AC-3 audio compared to using the recommended .MP4 with 192kbps AAC-LC audio that YT recommend?
Actually the YT recommended BR for audio of 384Kbps seems quite high for AAC-LC, especially seeing as the max. you can set in the VPX .MP4 export settings is 192kbps.
1080 50P Magix export template uses a GOP of 50 but YT recommend to set it to half the framerate ie.GOP = 25?
I presume the "moov atom at the front of the file (Fast Start)" YT requirement is covered by ticking the "Streamable" box in the Intel Advanced encoder settings?
I have seen pretty impressive quality from YT uploads by members of the forum and others so any thoughts and observations of what might and might not make a difference in your experiences would be much appreciated.
