Hello,

I  am new in encoding and I am facing a problem in proper synchronizing the video with audio.
e.g.,
I have two movie sources, the first movie is of 2:40:30 and the second is of 2:11:26.
In the second movie, many scenes are cut from the movie and I want to properly synchronize the second movie audio over the first movie video as the second movie is only dubbed in local language and movie scenes were cut during dubbing.

I am using gMKVExtractGUI for extracting audio/video/subtitles/chapters and MKVToolnix for merging it.

I believe you're about to make dual-audio thing, original audio and the dubbed one's. else, you are willing to add dubbed audio on original movie video?

1. Possibilty > Rip both audio's and use some type of audio editor, where you can run original audio/language to those cut scenes to keep original audio to cover the runtime. and export the audio, use this exported version on encoding software and add original audio as in default, or make dual-audio or keep the single audio according to your choice if you want dubbed audio on the original movie. (While ago, a friend of mine told me, he had watched a hindi dubbed version of tamil movie, he noticed a bunch of sessions contains tamil only and other rest was in hindi, it was around 17 minutes from overall runtime)

No matter what you do your going to have 29 mins of different dialogue/audio if you want to sync audio 2 onto 1...?...(depending on what it is)

Easiest way to do it is by running duel encoders:D....no need to extract anything first.
This will give you a perfectly sized Hybrid Audio File:-*
(i did the same thing previously for Midway)

Your audio file will be 2:40:30....2:11:26 will be audio 2 with audio 1 used to fill in the missing gaps...
You can then make a sub file to hard/softcode over the missing audio pieces...or find the missing audio first and stitch that in.

right now im just making some test of ffmpeg, what would you change or add of it?

Do you like command line for some reason, Handbrake provides a good GUI if you wanted to make
things easier for yourself.

As to your settings I always prefer 2 pass encoding set to an average bitrate.

Also, what is the "copy -c:t?" for ?
I actually had to look up 't' as Ive never seen it used, its for attachments.
Perhaps you actually mean to use 's', for subtitles ?

Yoange wrote:

"-c:t? copy" is for copy all attachments in the file and "?" is when you are not sure if there are attachemts, so you set "?"
and yes, "s", is for subtitles, also you can use "-map_chapters 0" to copy the chapters.

I don't know if this is considered coding...
I'm not real savvy so bear with me.
I use Plex to watch movies on my TV. For some reason is doesn't load TV shows so...
Lately when I try to convert and burn an MKV file ConvertXtoDVD won't load it and says "codec tag unsupported."
I come back, download a different MKV file, same TV episode and it will convert and burn.
I use Handbrake but I'm just wanting to know what the difference is in MKV files and what to look for when downloading.
You guys are all alright in my opinion. 😁

Hello,

I'm using Windows 10, Nvidia GTX  VGA with VLC (latest update, default settings) and I've noticed nasty artifact effects at/on dark spots/scenes during every 1400 MB 1080p movie releases (see picture).



Are my settings faulty, should I tweak something or how can I improve this on my end? (thinking about Nvidia Control Panel perhaps etc)

To be honest...that looks like the pattern on the very dark curtain in the background.....very faint but noticable pattern that looks like noise due to the very slight change in lighting needed to show it.

It could also be due to the size limits on the file...always 1400MB meaning the bitrate is forced to fit, instead of taking what is needed when encoding..?....meaning it will always try to save bitrate on dark scenes

Its just one screenshot I made, I've been watching horror movies lately and as you can imagine, there are a lot of dark spots throughout the movies... so its quite noticeable. I've noticed this pattern and wanted to ask around if I can do anything to make it better.
