converted video are disturbed on TV
« on: December 16, 2018, 09:25:33 PM »
Hallo,
I'm very new to avidemux, video editing and thsi forum.

I'd like to watch some mp4 clip on tv but my LG TV doesn't show it, i think the TV doesn't support the codec.
So i dowloaded avidemux 2.7.1 on my linux mint and after some try i can watch the mp4.
But as on pc is all good, in tv i see the image disturbed by trembling, tryed in anoter TV same results.

Where is my mistake??

 Here the original clip properties

If a TV set completely rejects H.264, it must be very, very old.

In general, you would be much better off with building from the current git or using the latest nightly build (appImage).

I don't quite understand what does this trembling might look like. Could you please provide a short sample of the source video, saved in copy mode? The resolution and aspect ratio is quite unusual. Is the source video interlaced?

As i say  I'm new to video editing..  just trying to make the movie run,

This is the sample created with copy
https://drive.google.com/file/d/1Rnc1oXzss1zs6CaGV3-7ZuIatmb3ODBy/view?usp=sharing
It flow good on pc and on the full hd tv bat not in the old LG

This is the sample converted with Mpeg4 ASP (ff) it is visible in the old LG TV and in the newest full hd but the image is bad, as on PC it works good.
https://drive.google.com/file/d/1-uMFUdpa5EZ-dj4NLI3pY8D7lekXX2Y6/view?usp=sharing 

I can't understand why the second works on pc and is not good on tv, i attached a screenshot of avidemux GUI

Hope you can watch the samples.

Thanks again and sorry for my bad english
Marco

Thank you for the samples. There is really nothing special with the video with respect to codec, especially it doesn't use any advanced H.264 features (profile: Baseline at level 1.3). Of course, I can't judge whether anything is wrong with the original MP4 container. Have you tried to remux the video in copy mode to MP4 forcing the usual 16:9 aspect ratio? If you do have to re-encode, H.264 with the Main profile would be much better than obsolete and vastly inferior DivX.

I am not aware of packaged builds from the current git master for Linux Mint. The 2.7.1 is getting old, there have been numerous important fixes since the last release half a year ago.

and to explain the problem i have took a picture from the TV image with the dirty visible

Hallo,
I just have done some more test:
setting copy to  video and copy to audio
output =mp4 muxer
setting aspect ratio 16:9
the video is ok in the full hd tv, but cannot play on the LG one :-(

here the link to the TV owner's manual at page of display resolution

https://www.manualslib.com/manual/1303976/Lg-M2080d.html?page=32#manual

also with this information I can't understand how to set the outupt, maybe you can...

The TV picture shows decoding errors which e.g. FFmpeg as used by Avidemux, VLC and many other projects either doesn't have or successfully conceals.

You should try re-encoding the video using the "Mpeg4 AVC (x264)" encoder in Avidemux. In the encoder configuration dialog, uncheck "Use advanced configuration" and set "Profile" to "main".

Display resolution has nothing to do with video resolution. It is relevant when you feed external video signal e.g. over HDMI to the TV set.

Judging from the file properties you posted, you have re-encoded the video and saved it using Matroska as container.

Only the manufacturer could explain why their TV set didn't like the former but accepted the latter.
