DAR 16:9 Sometimes pads when video is already 16:9

[JezzaT]

I created a profile to test this

  Code:

      <Profile id="mpeg2DAR" name="mpeg2video 16:9" extendsProfileId="1">
      <Transcoding>
         <Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" DAR="16:9">
            <Matches container="*" />
         </Video>
      </Transcoding>
      <OnlineTranscoding>
         <Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3">
            <Matches container="*" />
         </Video>
      </OnlineTranscoding>
   </Profile>

And it seems transcoding of some 16:9 videos correctly(I assume) doesn't pad i.e. add something like -vf pad=1280:720:0:96:black,setdar=4:3

These files get padded and end up displaying incorrectly in 4:3(including playing the stf file in VLC)
http://www.demo-world.eu/trailers/redir ... sprite_mix).rar 720x480 (16:9)
http://www.demo-world.eu/trailers/redir ... rience.rar 720x480 (16:9)
http://www.demo-world.eu/trailers/redir ... g_life.rar 720x576 (16:9)
e.g. ffmpeg -y -c:v mpeg2video -qscale:v 1 -vf pad=1024:576:152:0:black,setdar=4:3 -r 25 -g 15 -c:a copy -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-197-mpeg2DAR-ORIGINAL.stf

These file don't get padded and display correctly:
http://tomtom2k5.free.fr/mkv/720p/calif ... le-hdq.mkv 1280x720 (16:9)
http://videos.hd-trailers.net/riddick-f ... r-720p.mp4 1280x720 (16:9)
http://videos.hd-trailers.net/riddick-f ... p-HDTN.mov 640x360 (16:9)
eg ffmpeg -y -c:v mpeg2video -qscale:v 1 -r 24000/1001 -g 15 -c:a copy -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-63-mpeg2DAR-ORIGINAL.stf

It seems me that all 16:9 and lower DAR e.g.14:9 and 4:3 should not be padded but this doesn't seem to be the case. Why is that?

This might be related to this topic: viewtopic.php?f=11&t=2956

What is your renderer model ? Sony Bravia ?

[zip]

Ok, looks like I've not been taking into account SAR (in this case anamorphic pixels of the DVD content) when comparing DAR. Should be finex in 1.3, hopefully it won't break other stuff. Will need proper testing (Illico )

[Illico]

Ok, looks like I've not been taking into account SAR...

Is it a regression ? I thought it was implemented.
I will retry with http://www.demo-world.eu/trailers samples with current version and wait for the next 1.3 version

[zip]

Not regression. But there was hardly anyone forcing 16:9 on VOB files. The check for if DAR has changed now takes SAR into account.

[JezzaT]

Another scenario to consider is where the SAR 1:1 and DAR 80:43. which displays with the correct aspect ratio natively on Viera and remuxed on Bravia so also(I think) no need for padding.

One of the reasons I'm looking into this is that my Viera doesn't play DTS but remuxing gives this problem with DAR viewtopic.php?f=5&t=5403&start=20 so I transcode the video as well with DAR 16:9.

[zip]

I'm not sure if it's correct on the TV. It might be a bit off, as it's relatively close to 16/9 but not really.

Your right - just had a closer look and there are small horizontal black bars on Viera both mkv and transcoded and padded - both look the same. Seemed to take up full screen on Bravia though but will have another look.

I have a some anamorphic x264 such as

Which currently gets trancsoded like this:

  Code:

-c:v mpeg2video -qscale:v 1 -vf pad=714:402:0:18:black,setdar=4:3 -r 24000/1001 -g 15 -c:a copy -map 0:0 -map 0:1 -sn

which come out very wrong i.e. no letterbox. Will the fix you make likely sort that as well?

How does it come out? Can you post an image? Or upload the file somewhere for me to test?

I have a whole bunch of movies that for some reason have the horizontal bars cropped off AND are anamorphic

Could you try the same FFMpeg command with this instead and see how it looks?

  Code:

pad=652:366:31:0:black,setdar=4:3

and also

  Code:

pad=714:402:0:18:black,setdar=4:3

to see which works better

Second is the same as what the Serviio transcoded.

Pay attention to quotes ("" ""), that you have to add for -vf option when you use windows terminal command (on serviio log quotes are removed) :

ffmpeg.exe -threads auto -i "INPUT.mp4" -y -c:v mpeg2video -qscale:v 1 -vf "pad=652:366:31:0:black","setdar=4:3" -r 24000/1001 -g 15 -c:a copy -map 0:0 -map 0:1 -sn -f mpegts "OUTPUT.m2ts"

Adding quotes made no difference besides the second vf params you gave ran fine without quotes

any chance you can trim your video (10 seconds or so) and upload it somewhere for me to test?

No, while it displayed OK in VLC with some thin letterbox bars, on the Bravia it cropped the left and right edges of the picture with very thin letterbox bars, on the Viera it displayed the entire picture with thicker black bars but not as thick as when displaying the original mp4.
