[Kaavalan]

Hi guys. I asked a question couple of days before. I got only one reply for it. Please clear my doubt.

This is meGUI doubt.
What is JVT?

My megui settings are in JVT I need to change them to isom mp4 format. Help me please

JVT = h.264 = AVC = MPEG4 part 10. Same thing.

JVT. Read here what it stands for

http://www.itu.int/en/ITU-T/studygroups/com16/video/Pages/jvt.aspx

In your context it is just a basic preset used by the encoder. If it has changed then you changed something within the program.

Thanx for ur reply. Can you tell me how to change it?. And one information to you when I use one click encoder it uses base media instead JVT. Please tell me how to change JVT to base media?

How are you determining this ?

And Why do you want this ?

I just did a quick test in megui and mediainfo reported this

Format                                   : MPEG-4
Format profile                           : Base Media
Codec ID                                 : isom

Codec ID                                 : isom

This is better settings than what I mentioned above.

Format : MPEG-4
Format profile : JVT
Codec ID : avc1

And this is what I'm getting.

1) Why do you care?
2) What version of megui, do you have updates, etc... ?
3) Does this happen only when you use 1-click, or how about normal encoding ?

Why do you care?
Because It's good settings than what I mentioned.

What version of megui, do you have updates, etc... ?
I installed 0.3.5 version. And Some updates were shown So I updated them.

Does this happen only when you use 1-click, or how about normal encoding ?
When I use 1-click encoder I get this results
Format : MPEG-4
Format profile : Base Media
Codec ID : isom

When I use normal encoding I get this results
Format : MPEG-4
Format profile : JVT
Codec ID : avc1

It doesn't make a difference in terms of "good settings" or quality. Its the same thing. It might have impact on compatibility with certain devices

I'm using ver 2220, using the development tree, "portable" version (options=> settings => extra configuration => use development update server) . I think 0.3.5 is a few years old

Thank you for your help brother. but still it's it JVT. how to change format profile? Do u know that"?

[poisondeathray]

Not sure. The x264.nl binary muxes mp4 that way, but other binaries use different methods. I think megui uses x264.nl unpatched (jeeb's builds)

e.g. using CLI

x264.nl
http://x264.nl/
Format : MPEG-4
Format profile : JVT
Codec ID : avc1

kommisar
http://komisar.gin.by/
Format : MPEG-4
Format profile : Base Media / Version 2
Codec ID : mp42

But when I use megui, it uses
Format : MPEG-4
Format profile : Base Media
Codec ID : isom


If you use megui's manual mp4 muxer you can change to mp42, or other formats like ipod, psp etc.. , But I didn't see the option you wanted

Try resetting the dialog options in megui . You can also ask in the megui thread at doom9

[poisondeathray]

ok you can take an existing file and remux with ffmpeg. It's mp4 muxer seems to do what you want. I used zeranoe's builds
http://ffmpeg.zeranoe.com/

ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mp4

input file
Format : MPEG-4
Format profile : JVT
Codec ID : avc1

output file
Format : MPEG-4
Format profile : Base Media
Codec ID : isom

Not sure how to get megui to automatically use ffmpeg method of muxing mp4

[poisondeathray]

And if you didn't catch the implication, the streams were copied with ffmpeg - ie. no difference in quality . These things are just labels or names. They are irrelevant (but some devices might not like certain "labels") so "Because It's good settings than what I mentioned." isn't really a valid reason

Thank you very much for your helping brother Can you tell me how to change the dialog options.

options => settings=> reset all dialogs

ffmpeg. Will this be the reason bro?

It was just an observation . A test.

Different muxers put different "labels" on the video , but some may cause incompatibility problems. Some use slightly different container specs. Muxing doesn't change the quality of the video or audio . "MP42" in my experience is the most compatible

okay bro. I'll change the settings and try !! but I have to find out the reason.
