It occurs sometimes that I have two parts/files of one movie which I want to append and to create one single AVI file.
When I use the "Append" function of VD then sometimes
I got the error message similar to "Cannot append because
the audio encoding is different"
How can I otherwise append them ?
Why not introducing an option/menu in VD
"Append with incompatible audio tracks" which let me append them but forces me re-encode the audio parts again.
In such a scenario I must specify a target audio format (e.g. MP3 128 bitrate CBR) and VD encodes the two audio tracks according to this new audio spec.
Can I expect such a function in future releases of VD ?

This would of course be useful, but it's not a trivial change because it requires restructuring the internal audio processing chain into a tree.

Nevertheless it is urgently necessary.
Is the implementation already planned/under work ?
By the way: I cannot understand why this should be so complex.
If the users adds a second AVI clip with an incompatible audio track then VD should just set internally a re-encoding-force-flag and popup a dialog window with a text like "Warning: Incompatible audio tracks. Saving not possible unless complete re-encoding of the audio parts."
When the user specifies then e.g. MP3 VBR 128 kbit then VD has all information for the audio re-encoding process.
What is the difficulty ?

Having the information and acting on it are different things.
Since you think it is so easy you can add the feature yourself. If you say that you are not a programmer, consider that this may explain your inability to understand the difficulty.
Anyway, there are solutions available using Avisynth. |

All I will say, is that there are a lot of little details that you are missing... the least of which is what happens when the audio for the first clip doesn't extend far enough to the beginning of the second clip. Modifying a 4MB source code base from one audio source to multi-source is not a one-day task.
Thread locked.
