Will do. And surely I will put Aften support to my ToDo list (even if with low priority)

If you used HCenc with 2-pass profile, undersize is really too much and there is a problem somewhere.

I use latest ffdshow stable release http://ovh.dl.sourceforge.net/source...0705_clsid.exe for everything: divx, xvid, mpeg2, mpeg1, dv, mp4, ac3, etc.

Hi,

is it possible to save a Title Setting as default? I would like to use AVStoDVD for converting DV-material so I always need to edit the video settings to "DV Source". Hope that I have not overlooked something...

And I found one missing entry in the "Default Language" settings: "DE - German".

Thanks in advance, Filbert

[gizzin]

The ffdshow version I was using caused those undersizing problems. I'm using the version you mentioned. But now I have a oversizing problem (50megs over). HC at smaller bitrates tends to oversize more. I just entered a custom size at 50 megs the default, and then re ran it and got to 4.36gb. So maybe when the bitrate is at lower 1500 - 2000. Have a lower default size. I'm running more tests tonight, the avg bitrate for these are 1500kb, roughly. To see if generally thats the case

I am sorry, but no it is not possible. Title Settings are dynamic, depending on the source title. It is possible (next release) to add a routine to detect if a source is DV coded and automatically toggle on "DV Source" in 'Title Settings'/'Video'.

What do you think?

Ah, thanks for reporting the missing language!

This would be very helpful, thanks! Will test it with my DV source-material as soon as a new (beta)build is out to see if it is working.

Greets, Filbert

After numerous tests, it seems that 1500kb avg and under always seems to oversize.

Whats the quality like at 1500kb and below anyway? It must be bad? I always try and keep above 3000.

There should be something wrong. This is my "only one" test with a short DV source log file (1351 kbps avg bitrate). Ah, video output is horrible, of course.

If you post a log file as well, it could be very useful.

1500kb avg is terrible, but trust me hc performs miracles at lower bitrates. Try any other encoder and you will see what shit looks like. I don't think there's a problem with avstodvd its just as the bitrate gets lower hc tends to oversize more. I don't have any log files I deleted everything, but I will run another test, today or tommorow and I will give you the log.

[Darksoul71]

I would disagree...while HCEnc is pretty much able to encode One CD movies with good quality I still find all libavcodec based encoders (QuEnc, AQE, Mencoder)
better at low bitrates. Even below 1 MBit.

The image is somewhat smoother / blured than HCEnc but has less visual artifacts.

[gizzin]

I disagree totally. Quenc is really blocky imo, and aqe i put in the same department as cce it tends to make a lot of noise. I never tried mencoder though. But thats getting to much off topic... everyone has their opinions and my tends to be infavour of hcenc especially with lumgain and AQ. Solves all the blocking problems at higher bitrates...hehe

[Darksoul71]

@gizzin:

But thats getting to much off topic...

Agreed

@MrC:
I´m currently trying to implement a "guided CQ'" interface for HCEnc similar to manolito´s HC_D2S which is compatible with the standard hc interface and thus not DVD2SVCD dependend. You can follow development here if you are interested:
http://www.vmesquita.com/forum/index...ic,8888.0.html

I might add a one pass VBR mode without CQ prediction as well.

Thanks for the hint, Darksoul71. I will surely take a look. Improving VBR 1-pass encoding would be very useful, because OPV is "a kind of magic", but sometimes inaccurate.

What about writing a DLL (maybe an ActiveX DLL)? That would be great, because its spreading and implementation would be very easy. Look at MediaInfo...

I do not know about you but I rather like to call an external program than accessing a dll

I agree if the DLL is not well written (crash) or it has a poor documentation/examples. Otherwise I prefer DLLs because they are more integrable with GUI and let a more accurate errors handling.

Just my 2 cents....

After trying 3 times I can't seem to get this dvd to author. Everytime I come back is error authoring or whatever, but it encodes properly. The only thing different is the source files are on a different hd...but I dont see how that will make a difference.

[gizzin]

I also get this error sometimes with certain avi files. ERROR, GetChannel: Attempted to request a channel that didn't exist!

This kind of error is common when the source file contains a (not DVD-compliant, in that case AVStoDVD retains audio) AC3 audio stream with a channels number different from your directshow AC3 codec mixer/output setup.

For example, if your file as a 5+1 AC3 stream and if you use ffdshow, be sure that audio decoder mixer is configured properly.

I ran into problems trying to keep 5.1 ac3 audio. The first time I did it, It ran through with ac3fix, but the audio was all garbled upon playback on my dvd players. Then I tried It again without ac3fix, but this time there was no audio, just the video. Finally I just re-encoded the audio and everything went a-ok. But no 5.1 surround booo. I tried it a couple times.

Yes, there is a little bug with ac3 retention in 2.1.0 release (and in 2.1.1 gizzin build).

Please force ac3 encoding and setup your ac3 decoder output to 6 channels, as I explained in a previous post to keep 5+1 sound.
