44.1 to 48hz

[Fozzee]

Hi
After trying all sorts of programs and resolutions I have settled at 1/2 DVD SVCDs. I can then convert to DVD at a later date.
My best results are using PowerDirector Pro 2.5 or PowerVCR2.
I capture at 480 x 576 8000 bitrate then encode down.
The problem is both these programs only capture at 44.1 hz.

If I use TMPGenc to encode to 1/2 DVD 48hz the sound is choppy on my standalone DVD player.
If I use the toolame encoder as a TMPGEnc plug-in the sound is mute upon playback on my DVD player.
Is it likely my DVD player won't play SVCD at 48hz??

Either way I'd like to know the best way to convert 44.1 to 48hz.

I tried WinDVR but I find it poor and often out of synch.
But I think the resulting SVCD sounded ok so it may be just the conversation I need sorting.

Cheers

Fozzee,

Are you sure that PowerVCR wont record in 48Khz??
I dont have it installed now, but it seems I made a custom profile of some sort. I started with the DVD-NTSC profile, customized it to CVD res and let er' rip. I then checked the properties of the resulting MPEG and if I am not mistaken, it was 48Khz.

The only problem I had with PVCR was that my audio was always out of sync...

I know use movie factory2 to do my 44khz --> 48khz and it does a reasonable job. Took it 3 hours to convert 9 VCD files @ 44.1khz to 9 VCD's at 48khz (plus adding the menus and chapters and such) Then I just burnt to DVD using Nero.

If I could get PVCR2 to stay in sync, it would be my first choice due to its EPG programming....

Well my video programs show it 44.1hz.
My videos are always 100% in synch with PowerVCR2.
With WinDVR at 352 x 576 or 480 v 576 it's hit and miss.

I have movie factory2 but doesn't it re-encode the video?

If the video is 352x480 @ 44.1 it will reencode, but I don't know if that program is able to only convert the audio to 48. How about you try and let us know? Thanks.

[Fozzee]

I want the final video to be 352 x 576 pal so that program is useless to me.
I am figuring i will have to demultiplex the video then encode it.
But what program to use?
Fastest and easiest to use??

Fozzee

[Fozzee]

OK
I just found my soundforge program has an mpeg plug-in.
I opened the video file and converted to wav.
Then I saved it as 48hz.
I'm off to try using this file in TMPGEnc.

I'll report back later.

FOzee,

When I get home from work, I will check my emails. I dealt with a guy named Swan over at Doom9 about the PVCR/48khz thing.

DVDnew....I used to demux, save to wav, convert to 48khz, convert back to mpeg, then remux back in with video.

It seems that Moviefactory2 is doing all this in 20 minutes per 43 minute VCD. I would assume it is only converting audio....

[Fozzee]

Ok Cheers

I assume that way I would........

1)Capture to SVCD resolution (PowerVCR2)

2)Convert to 48hz (using MF2)

3)Encode to 1/2 DVD. (with TMPGEnc)

Fozzee

[spidey]

You can use TMPG and SSRC to convert the audio. See here or the VCD conversion one.

[Fozzee]

Does it do a good job??
Tried toolame and my DVD player player the file back silent.
I've got Sound Forge and just resampled a 40 min video file from 44.1 to 48 with anti-aliasing in 10 mins.
I'm going to encode in a minute and see how that works.
I'll try your idea too.

Fozzee

[bamafamily]

Fozee,

I would like to know how that goes.
If I could do a batch convert in Sound forge and have it stay in sync, then DVDMF2 will process very quickly.....since it needs no re-encoding (in my case anyway)

thx

bama

[Fozzee]

Well I tried SSRC as an external program with TMPGEnc 2.58.
I got an error!! It says TMPGenc doesn't support it.
Off to see how my resampled wav works.

[Fozzee]

Oh b*****
It seems it may be my DVD player not liking XSVCD.
I tried creating a 1/2 DVD Pal at 44hz.
My player didn't like that either.
I got the same slight stutters.

Anyone got any ideas.

Fozzee

[bamafamily]

Fozzee,

What is the bitrate you are encoding down to???
On my Apex, it started stuttering around 5000 with SVCD's.
Might be different for yours.

Might want to try a small clip and encode it down to say 2500CBR or something....

As an aside, most of my problems were answered with the latest software release of the winfast PVR software...

good luck

It gets WORSE!!!!

A normal SVCD plays like crap now!!
wonder if it's the burning process.
I'm gonna try another program now.

Fozzee

[Supreme2k]

For the record, the latest version of PowerVCR2 Deluxe does NOT allow capturing in 48hz, in ANY resolution/profile. That includes any custom profiles. The audio bitrate only goes up to 44. It's my favorite recording software, regardless of this one minor flaw.

[Fozzee]

My favourite too
Have you tried Cyberlink PowerDirector Pro 2.5?
Very nice captures too.

Fozzee

[bamafamily]

I really like PVCR except for the 48khz thing and for some reason, I would start losing sync after about 12 minutes at 1/2 D1 resolution.

Now that Winfast has fixed that, I will probably keep that. The fact that EPG(titan TV) works now makes it really easy to use....just got to find the mix as far as bitrate, CPU resources and DVD player compatibility goes.

[Fozzee]

Ok
I just used the same source file to make VCD Mpeg1.
The sound is fine!!
How can I sort this problem?
The only thing I will say is the original file is just over 40 mins long so I had to adjust the bitrate to 2400 could this have made a difference??

Fozzee

[bamafamily]

I am not sure....
All I know is that I try both Bitrates and burning speed combinations to do things right.

I currently burn my movies on CDRW at 10X on my Liteon CDRW. The fuller it is, the slower you need to go

On my DVD Writer, if the DVD is less than 4GB, I will burn at 2X..If it is over 4GB I will burn at 1X as it gets a tad finicky toward the outer edges of the media.

[Fozzee]

I just encoded the first 10 mins of the source video to......

352 x 576 mpeg2 bitrate 2520 48hz.

Sounds fine

Now for the whole file wish me luck.

Fozzee

[erzug]

I've captured with Wincoder and the audio is also 44.1K. I would bet that most if not all of the capture software defaults to 44.1K.

[Fozzee]

WOW
20 coasters later!!
It appears the problem was bitrate when encoding to CVD.
I thought i could slightly lower the bitrate to fit the whole file on 1 cd.
I WAS WRONG!!
My player will only accept standard bitrate for SVCD on XSVCD , CVD or 1/2 DVD whatever u choose to call it.
So it wasn't a 44.1 to 48 problem after all.

If at first u don't succeed try and try again.

END OF THREAD

Glad you figured it out......

i open the video with VIRTUAL DUB then turn on the AUDIO FREQUENCE change from 44.1-48k then frameserve it through cce or tmpg. never out of sync.
