.ts files vs .mk4 - .ts files are very efficient?

[jam_zhou]

So, I'm transcoding my .ts recordings to .mp4 and noticed that the .ts native recordings are actually quite efficient. Right now I'm reducing my recordings to 900 kbs in mp4 format using the normal profile in handbrakecli and it's doing a decent job. I've got an I7 with 12 GB of RAM and it transcodes 1 hr show in half an hour. The resulting file is 600 MB from 1500 MB for a 1 hr recording.

After all the work on figuring out handbrakecli, I came to wonder if I could just reduce the bit rate of the native recording and still have good picture. I only have 32" LCD so I'm not too picky. Also, I'm recording HD channels through component but not all my recordings are in HD. Is there a way to do this in the config.xml file of npvr?

Thanks.

You mean automate the transcoding? Take a look at PostProcessing.bat: http://www.nextpvr.com/nwiki/pmwiki.php?...Files#toc5

No, I have the transcoding all figured out. I was wondering if I could just set the recording bit rate in npvr and skip the transcoding all together. I would like to drop the bit rate by half.
