AVCHD to Mov issue with HDMV Presentation Graphic Stream subtitles

A lot of mts clip include subtitle track with « pgssub » codec (HDMV Presentation Graphic Stream subtitles).

FFMpeg does not support pgssub encoding (only decoding). In this case you will get the following error :


Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:1 -> #0:1 (copy)
Stream #0:2 -> #0:2 (pgssub -> ?)
Encoder (codec none) not found for output stream #0:2


To fix it, you can use the folowing work around. Note that the output file will not contain any subtitle.

The fix :

Use the preset named « Rewrap Mov » and uncheck the box « All streams » :

Start the encoding, it will be fine now.

We will propose a real fix in the next release.
