Muxing and Audio ?
Hi finally got the video problems solved(i hope)
but i can't get the audio to be in sync-i have beeen using headach3e and bbmpeg for a year now with no problems (with tmpge) Is there anything different needed to be done for Mencoder I did an avi and got the audio to be in sync but all dvd rips i've tried the auido is way before the video,i don't know if this is important but all ac3 files i've testesd have a delay but i thiought this is taken care of in headach3e Any suggestions Thanx |
Hi bigggt,
In fact, should there be a delay in the audio it should be noticed in the audio file name like MYMOVIE AC3 T01 3_2ch 384Kbps DELAY 100ms.ac3. When muxing you will have to advise the muxer of such a delay. For instance in Mplex/bbMpeg there is a panel for choosing the pack, video, audio1 and audio2 startup delays. Make your necessary changes there. Cheers |
thanx rds_correia
I do see that but in headach3e it loads the delay automatically and doesn't that take care of it I have had many delays but never had to adjust anything when i used bbmpeg before as long as headach3e did the delay Edit-ok just tried changing the delay in bbmpeg by -83 ms but it doesn't change anything :oops: |
OK did another movie and something is wrong,with avi everything works ok but dvd i can not get.
I thought i was doing the audio wrong but it seems that the final video is playing too quick(like 2 times the speed) any ideas |
There's something wronmg with IVTC routines ("forced film")
I am checking this now. :wink: |
Oops
Sorry bigggt, I didn't notice your post until now. It seems that VM already found something and is probably going to fix. Anyway I assure you I have no problems with PAL sources. Let's wait for VMs fix :wink: Cheers |
Looks like there's no need to use any IVTC filter if the input is fake telecined as DVDs with pulldown (movies). So do this is MencodeMe(0.22): on file operation, leave at none, and set the framerate to 23.976. This should work, accordingto this:
http://www1.mplayerhq.hu/pipermail/m...ry/030123.html But for telecined AVIs (captured movies) or hard-telecined DVDs (some anime/cartoons), I am still trying to figure out. The IVTC filters don't seem to work... :( |
Could the following be helpfull?

Thanks, unfortunatelly I already knew this documents. :( Looks like the proper mencoder ivtc filters, i.e., ivtc and detc doesn't work right and cause sync issues. I did a stackhorizontal, comparing with telecide(), and seems that they drop frames randomly :!: The only way to ivtc a stream that doesn't cause sync issues is really wierd: kerndeint,divtc divtc is a ivtc filter for de-interlaced video, yes, sound wierd, I know. There's no mention about it in the manpage nor in the mailing list. I only found out about it using mencoder -vf help. This seems to be the only filter that keeps a 5:4 output not causing sync issues. I was only surprised because I searched the mailing list and noone posted nothing about this. :? Anyway, this seems to work fine, causing no ghosting despite the initial deinterlacing needed. And yes, I tried all detc and ivtc parameters. No success. EDIT: I watched in the DVDPlayer, and seems like this filter drops the wrong frames, causing jerkiness. So no sucess yet. :( |

Nice tests! :D
Unfortunatelly, I couldn't find a IVTC filter/combination that works correctly. For progressive VOBs with pulldown flag, we should use -ofps 23.976 without fps. I'll fix this in the next mencodeme release. I also discovered that transcode (another linux encoding package, also featuring libavcodec) has a decomb port, but unfortunatelly transcode doesn't compile on cygwin. |
Thank You Guys ,I(well you :wink: ) finally got it working ,it was definately a problem with forced film because i left it as none and got my first dvd to be in sync :D
Now on to the next question-This is not a problem but a not knowing how on my part I can't seem to get the proper ratio,i don't know how to get it to put it in manually I tried laoding the source into moviestacker and using the ressize numbers. The only reason i know its off is because in tmpge i get big black bars(top and bottom) but with mencoder i get small ones HOw do i get the proper values Thanx again |
Click on "Unlock advanced" and use moviestacker values. But you shouldn't have problems with the built-in resize calculator. Could you give me more details?

@ vmesquita
I did the unlock thing,what i mean is i am not sure which numbers from moviestacker to use :oops: This is from moviestacker Source 720x480 Film Pixel 720x480 Crop 712x480 Resize 496x336-This is what i used is this correct I also checked with avi codec the info on the final mpeg(from Mencoder) and it says 4:3 but i selected 16:9 I will test again to make sure becuase i have so many things i am trying to test right now i could have made a mistake(i will test this and nothjing else right now) |
What was the target resolution?
|
OOPs sorry -528 x 480

You can't use MovieStacker resize value directly in Mencode-Me, because it doesn't crop the black borders. (I forgot that) I think the problem with mencodeme internal resizer is that you are selecting 16:9 A.R., but actually you want to create a 4:3 A.R. MPEG, with widescreen matherial :!: This is completelly different.
You see, you don't have to select the source aspect ration in mencode-me, it autodetects. You have to select destination aspect ratio, this is generally 4:3 unless you are making an anamorphic KDVD. :wink: For KVCD/KSVCD, you should use 4:3, the proportions will be calculated correctly. Try this, and use the preview function before encoding to check if it's ok. :wink: |
@ vmesquita
Thanx buddy working good now,i was selecting 16:9,but 4:3 works perfect Thanx for your help seems like everything is working properly now |
