Vera 4k on hd tele

Thank you both for your help. My HD tele does not support PCM audio as I found out after I had downsampled a test clip of 4K video - I just had a silent movie - I downsampled a clip via software but which is okay for a few clips but not dozens. That’s why I was checking whether Vero 4k will also convert the audio signal as well as the video.

Thanks again

That is very surprising. What is the make and model?

Can you also post mediainfo for that clip you made?
Please see the mediainfo section in How to submit a useful support request - General - OSMC.

You may have to install mediainfo on your PC.

I am not handy for the tele details at the moment but from memory it’s a Panasonic Vera flat screen 47" while the audio is a 16bit RAW 2 channel PCM

Update, my tele is a Panasonic TXL47ET5B Viera and after going through the sound settings there does not appear to be an input option - only the usual bass, treble, surround sound etc - also last year with some HD clips - although they played great (just insert the memory card straight into the tele) no sound as the audio was PCM

That TV should support audio from the Vero 4K without issue, otherwise I’d expect no devices to give you sound via HDMI.

As @grahamh suggests, MediaInfo output for a clip that produces no sound may give us some clues as to why.

Thanks again for the advice - here is the Mediainfo - it’s long -

So that appears to be the original (4k) file. Please post mediainfo for the resampled file.

I no longer have the resampled file but have listed a file from another camera where the clip plays fine but no audio on the tele…

Are you saying that when you plugged a memory stick with the problematic clips directly into the TV that there was no audio?

Just as a heads up most ‘UHD or 4K video’ that comes from UHD Blu Ray Discs is also ‘HDR’ (High dynamic range) and Wide Color Gammut.

Your HDTV doesnt support these, and unless something has changed recently when I tried them the Vero doesnt do any form of tone mapping.

The end result of this will be picture will look quite ‘flat’ washed out and grey and you’ll get a far more accurate image on an 1080p display from an SDR 1080p file.

The Vero utilizes dithering (and has since the beginning, if I’m not wrong) to bring a HDR source image to an SDR screen with the limitations there are… It’s not adjustable though and not all results might be pleasing in every situation.

Thank you for the information - just out of interested to my eyes the picture looked okay (but it could be just me) with the Blu Ray clip and also with the 4K clip that I downsampled with software (Handbrake) to 1920 x 1080 only trouble was - no sound - from just installing the memory card into the tele slot.
I got round the problem by connecting the camera to the tele with a cable - playing the clips from the camera.
However my plan now is to play the clips via the Vero 4k - I was thinking I can just store all my clips on a HDD …leave it with the tele and thats also another back up …

There is really no reason why the audio shouldn’t come through with any of these files. If you can share a small sample (perhaps the second clip or just a few seconds of the first one) we can check if it plays OK on vero and I could see if it plays on my Panasonic.

Thank you again for your help - I did try to upload a clip but the message said it had to be one of the following extensions - jpeg etc etc
mts wasn’t listed …assume no movie uploads …

You can use something like Dropbox or MEGA

There has been HDR to SDR conversion for some time.

OK, the problem is that PCM is not normally encapsulated in mp4 or mts files. Your TV will not therefore play the audio from these files when played direct from a card, USB stick or over a network.

Vero, however, is less fussy and will separate the video from the audio and send both over HDMI. If you can send a clip, we can double check that.

@Smokeyone:

You can upload some clips here: https://collab.osmc.tv/s/GOcNSR7cYhBKO8p

A post was split to a new topic: Washed-out colour

Thank you all for the upload suggestions/links - tried to upload and waited and waited - so thought maybe the file is too big so tried to edit the file but my software decided to crash - so after several attempts my software still either freezes or crashes - not my day yesterday - laptop decided it didn’t wish to charge …
Looks like PCM will be okay with Vero

Thanks again

You’re in the UK, so worst case scenario is it warrants a return via the post office, but I very much doubt this will be necessary.
