Ok, good hint. Thanks.

I have noticed on the log file that AVStoDVD switched to FFMpegSource. Probably the DirectShowSource may help, just install flvsplitter.

If this does not help, what about switching back to HCenc 0.25 instead of HCenc 0.26beta?

My reference is good old DVD2SVCD, it calculated a video bitrate of 4955 kbps, and the resulting file did fit perfectly on a DVD-5 (ImgBurn reported 99% fill rate).

With AVStoDVD the video bitrate varied depending on the output format:

For DVD structure, ISO image or Burn DVD the bitrate was 4927 kbps. This did work perfectly.

But when selecting Elementary Streams or Muxed MPEG2 files the video bitrate was 5037 kbps, and these files could not be burned to a DVD-5 blank, they were way too big.

What is wrong here? I think the video bitrate should be the same no matter which output format is selected.
I have reserved some extra space for DVD structure, using following rationale:

Code:
        If OutputSetup >= DVD_Folder Then
            DVD_Size = Int(DVD_Size * (0.995 - 0.01 * DVD_Time / 3600))
        End If
and that formula applies only if the Output Setup is 'DVD Folder' or higher.

Let's say if the elementary assets are then used to create a DVD structure, then same formula should be applied (but why not using directly 'DVD Folder' as output?).
If the elementary assets (or the muxed mpeg) are stored as they are, then the extra space should not be added. Otherwise the predicted output space will not match.

Does it make sense?



Bye
