23.576 , can not Authorizing in Mainconcept and Tmpenc !!!

[din4na]

Helo Guys

I have a small problem now, but dont know how to fix

Yes, first, i have an avi file, with 23.576 frame per second, 2 sound channels, everything is oke

BUT , when i use Mainconcept or Tmpenc to convert it to DVD , i think everything will be oke, yes, but he he, the sound is out of sync

Because, mainconcept and tmpenc only allow me to convert the avi file to framerate 24,25,29.97 only ( , with both PAL and NTSC system .

And that's why,its make my sound is out of sync .

Lolz, and now, i dont know how to do ?

How can i convert my avi file from 23.576 frame rate to 25 with sound sync ?

Thanks for any help ^^

[BJ_M]

in both -- its supposed to be 23.976 progressive and add pulldown ..

try it -- it works ..

but if source is 23.576 really .. you will have to change its speed to the correct ...

[din4na]

Thanks thanks, it was a typo, my source file = 23.976 frame/s

But how can i do this :

"in both -- its supposed to be 23.976 progressive and add pulldown" .

In Mainconcept ?

And its will fix my sound sync ?

THanks

Check out that thread. MainConcept may have a pulldown option too, I don't know. But TMPGenc can definitely do it during encoding and pulldown.exe can always be used after encoding.

[reboot]

In Mainconcept mpeg encoder, click Details, Advanced, Multiplexer Settings. Adjust pulldown.

[BJ_M]

hmm - not quite ..

Main concept adds pulldown when you set source as progressive 23.976 from the drop down and have already selected dvd profile -- go to the next tab and you will see 3:2 listed and greyed out as it is pre selected for you ..

[din4na]

Thanks guys, but i can only use Tmpenc plus to encode my movie only without sound out of sync

With Mainconcept, i can select 23.976 frame rate NTSC in Detail/setting BUT seem to be its not work !! Because when i push the advanced tab again, the setting is back to 29.97 frame rate not with 23.976 (

How can i do this in Mainconcept

Bumpa ^^

Whats wrong with using 29.97?

[reboot]

Select mpeg2 as your Output type.
You can then select any fps.

Sorry but Mainconcept still doenst work for me ....

I tried DVD and MPEG2 output but the output file still has sound sync problem, and i dont know why, of course i chose 29.997 drop framerate NTSC (

[adam]

Its not as efficient as 23.976fps. Its interlaced, which requires alot more bitrate and is something that most encoders just generally don't handle as well, and it also has 20% more frames per second, thus its like lowering your bitrate 20%. (Same amount of bits per second having to represent 20% more total frames.) You can also get better quality on progressive scan devices if you store the video at 23.976fps progressive.

[BJ_M]

adam -- in MC , when you select 29.97 as target and set source to 23.976 .. it automatically adds pulldown for you --
it is still encoding progressive ...


that is - if you use the dvd profile

[adam]

I was just talking about encoding in NTSCfilm vs NTSC in general. I've never used MainConcept.

i have....and it's not all that

but, as BJ_M said, ifyou tell mainconcept the source is 23.976 and the destination is dvd, it should encode w/o unsyncing.

Hello BJ, thanks for ur reply but seem to be i cant use MC to encode as you said .

Yes, i chose DVD profile and MPEG2 profile but the output file always out of sync !

my source = 23.976 and when i open my file with MC , and select NTSC system, its wont let me chose some options but i tried with NTC 29.97 frame drop down for ntsc movie , but its sucky !

How can i do

[din4na]

Bumpa, help me plz

[funkguy4]

after you select dvd profile, do u have some sort of optoin to unlock options, or can you make a brand new profile to suit your needs?

23.976 fps
pulldown

[BJ_M]

you can select generic mpeg2 to unlock settings .... but thats not his problem -- his sound is out of sync which is a problem that is hard to pin down with out knowing a lot more facts ..

key words "lot more facts"
i think we're talkin' VDub file info scrn shot and mainconcept scrn shots.

Hello guys ^^

First, i dont know how to create NEW profile in Mainconcept .

Second, when i chose MPEG profile in Mainconcept, i CANT select the option NTSC Film rate pulldown

And my source file = avi = 23.976 frame/second !

Can you give us more info on what kind of audio is in the avi file? If it a AC3 or VBR. that may be the problem.

[din4na]

Hi again guys, my when i open my avi file with virtual dub, the program report that my file has invalid ABR sound stream .... -2 channels

In most of the case, i alway decode it with virtualdub mode to *.ac3 file, or use virtual dub to reencode the sound to 2 channel VBR and its work great , because most of my avi file has frame = 25.000 and when i convert it to dvd compliant , its good . But this time, avi file = 23,976

Does this help ^^

Thanks for any help .

Ps: I tried to decode it with virtual dub mod, but the sound still out of sync because the frame rate issue

[funkguy4]

what your problem is is that when u encode mainconcept is changing the source fps from 23.976 to 25. So the video's going faster than the audio. What you need to do is either frameserve from AVISynth to BeSweet or decompress to a WAV (which will be quite large btw) and then recompress to either MP2 or AC3. I recommend AC3, but in PAL land you can go either way.

din4na,

I was having the same problem as you using Mainconcept Encoder but I just solved it.

BJ_M hit upon it in about the second reply in this thread when he said it is supposed to be "23.976 progressive and add pulldown" but the way Mainconcept works isn't obvious.

Everytime you select NTSC and MPEG2 it defaults to 29.97 on the front page and not the 23.976 you want. When you go into the Details and Advanced tabs to try to alter the framerate and apply the pulldown the pulldown is greyed out and changes made to the framerate are forgotten when you get back to the front page. It was bugging the hell out of me.

But I found that all you have to do, before you alter the framerate under the Details tab is to change the Field Encoding tab to Progressive first before making any other changes. It defaults to Bottom Field first and this is what is screwing things up.

Now you can change your framerate to 23.976 and then click through to the advanced tab and the pulldown box is selectable. Change it to 3:2 and job done.

I selected Elementary Video from the front screen so that I just got the video encoded and then used FFMPEGGUI to make the audio track.

Opened up TMPGENC DVD Author, dropped the video file and then the audio file into the project and then Begin Output.

Burnt the project to a disc and then popped into my multi-region player and audio and video was perfectly sync'd and no jerky video.

Job done.

Hope this helps you or somebody else banging their newbie head against Mainconcept's wall like I was!

JA

[din4na]

Thanks alots JA , but i want do everything in Mainconcept but not with 2nd program ) .

Because, if i use Tmpenc plus to encode my avi file , its work very good , i chose elementary options for my file , and no audio/video sync with my file .

But , with Mainconcept, as you know :

When you go into the Details and Advanced tabs to try to alter the framerate and apply the pulldown the pulldown is greyed out and changes made to the framerate are forgotten when you get back to the front page. It was bugging the hell out of me.

Its suck then , ( , i cant change anything with Mainconcept . Lolz

[jimmalenko]

What about encoding with TMPGEnc (video only), then using ffmpeggui or headAC3He or besweet for the audio ?

[din4na]

Yes yes , Jimmy, but i want to do it all in Mainconcept )

With Tmpenc , i can encode audio and video separately without sync problem )

[funkguy4]

TMPGEnc = better , but let's not get off topic

[jimmalenko]

Yes yes , Jimmy, but i want to do it all in Mainconcept )

With Tmpenc , i can encode audio and video separately without sync problem )

So encode both in Mainconcept, then demux the video stream out, discard the audio it creates, then do the audio seperately with ffmpeggui or besweet and mux it with the video ?
