What FFMpeg settings do you use?

[top_cat]

I'm trying to set up GB-PVR to encode my output to XVID or DivX but keeping the quality high. I've found the default settings for XVID to give a very poor result.

So I was wondering if anyone had a Custom FFmpeg Conversion settings from config.xml which produces good results?

I tried creating my own

Code:

<Conversion name="XviD HQ" cmd="-y -i {SOURCE_FILE} -f avi -deinterlace -aspect 16:9 -g 300 -bf 2 -s 720x400 -f avi -ab 128 -ac 2 -vcodec xvid -b 1250 {DEST_FILE}" targetExtension=".avi">

But I this did not work as the quality was exactly the same as the standard XVID and certainly not widescreen.

So if you have managed to create a high quality XVID custom FFMpeg settings please share

change this part: -b 1250 to something more like -b 1250k or even -b 1800k for better looking results...medium rec. bitrate is over 3000k..

i use instead "-qscale 4.5" as this keeps a constant quality and varies the bitrate when needed...
adjust up and down to see what looks good to you and is still small enough..

Thanks for your help.

I've changed the settings to:

<Conversion name="XviD HQ" cmd="-y -i {SOURCE_FILE} -f avi -deinterlace -aspect 16:9 -g 300 -bf 2 -s 720x400 -f avi -ab 128 -ac 2 -vcodec xvid -qscale 4.5 {DEST_FILE}" targetExtension=".avi">

Does that seem better?

I'll start encoding something now and let you know the results but if you spot any other problems with the above code please let me know.

Thanks

Those settings did not seem to work, I got a 220mb file but it wont playback and only took a couple of minutes to create (not long enough).

pBS: would you mind posting the line from your config file so I can use that?
