PVAstrumento creates beeps and blops?

Recommended Posts

Salut !

 

I just tried to convert my MPEG recorded File to PVA because I wanted to append two files together,

but then I found out that after converting to PVA the sound got damaged with unregular beeps and blops.

 

1. has anybody an idea ?

 

Of course I tried to watch the original PMPEG, but this is playing well !

 

2. Is there a tool to cut / append mpeg files without need to convert 1000 times ? Or even just cutting would be fine !

 

thx.

Salut !

 

I just found out that I blamed PVAstrumento unreasonably. It is PVAcut that produces theese beeps and blops !!!!!!!

Furthermore PVAcut destroyed my synchronisation !!

I Just checked The files, and here is what I did....

 

1. recorded mpeg2 stream

2. converted to pva with PVAstrumento this is the output:

 

***

*** PVAStrumento 2.0.26

*** running at 03-05-2003 15:39

3) then I appended two of theese mpg files with PVAcut. I just loaded them sequentially, selected all frames, pressed ADD and repeated with the second. Then I saved the whole stream as pva.

Hello!

 

Just have a look in "Deutsch - Probleme mit: PVA, PVACut, TMPGEnc". You should try to disable "calculate new PTS" in PVACut, but it is explained in the "deutsch"-part in greater detail.

 

 

Bye, Oliver

There's a tool that can cut mpeg2 files. It is called MPEG2Cut. Try it...
