Title: Can you covert JTV Files to another format
Post by: trevoraiston on June 24, 2015, 06:41:45 pm

Can I convert recorded jtv files to another format e.g. mp4 or something I can use on a non jriver enabled PC?

You can convert them manually.

Go to Video, and select ones you want to convert, and choose Tools > Advanced tools > Convert Format...

I just did this myself actually to convert from JTV to a TS file - very useful.

Just wondering out of Interest to convert a JTV File from a 1080i TV Signal to TS (Transport Stream) format - what resolution would I choose to keep the exact same quality/resolution as the JTV file?

H264-TS 720p? But 1080i isn't actually 1080p - it's more like 720p... so would I choose H264-TS 720p?

Also what does the AUTOFPS dictate? e.g.:

H264-TS 720p AUTOFPS
H264-TS 1080p AUTOFPS

Not important - just curious!

At this stage, there is no "remux" option that would keep the content the same (1080i) and put it into a TS container (but one day maybe).  So for now pick the profile that suits the device you will play it back on and MC will transcode it into that format.  The "closest" profile for now is 1080p but the file will be larger than the original.  Try a couple of the options and see what you like the look of.

1080i is still 1080 lines (it's two different sets of 540 lines) so by converting to 720p you will be losing resolution.  Video transcoders usually have options for deinterlacing, which would be neccessary to convert to "p". So choosing 1080p will (presumably) double the size of the file, as each 540-line frame will be converted to 1080 lines, but keep the resolution. At least I assume that's how deinterlacing works!
