Vegas 11 / only 44.1kHz audio output -- problem still there? #22

Closed GoogleCodeExporter closed 3 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Sony Vegas 11.0 (build 683) 64-bit / Win7 64-bit
Project Settings/Audio -> set to: 16bit/48kHz/Stereo 

2. In the "Render As"-menu in Sony Vegas, the audio properties for DebugMode 
Framesever shows as 44 100 Hz/16bit/Stereo. That seems to point in the 
direction that the the audio has a wrong sample rate already at this point?

3. Trying to create a Quicktime ProRes video thru FrameServer by using ffmpeg 
-- ffmpeg also detects the Frameserver stream's audio as 44.1kHz instead of 
48kHz. Only way to override this is to use the "-ar 48000" switch in audio 
encoding which will forcibly resample the stream coming from frameServer @ 
44100 to 48000 kHz. No audible flaws in the audio in output file, but the 
sample rate mismatch is a bit worrysome considering exact audio sync?

What is the expected output? What do you see instead?

Expected to be able to render audio as 16-bit/48kHz, but the stream seems to be 
44.1kHz, regardless of the project audio settings being set to 48kHz.

There was another user asking this same question, his/her problem seemed to be 
related to Ripbotx264 (see: Issue 20) - or maybe he was mistaken and there 
really is a problem creating a 48kHz audio stream from Vegas 11?

What version of the product are you using? On what operating system?

Latest version of FrameServer & Sony Vegas 11, both 64-bit.

Please provide any additional information below.

Any help highly appreciated! Thanks for the great software!

I see the same issue described above. I am trying to encode using FrameServer 
and StaxRip from a 48 kHz audio source (AVCHD from a Sony SLT-A57 camera). I 
tried exporting to WAV separately and encoding the final audio from that but 
then I am getting A/V sync issues.

FFMPEG identifies the stream as pcm_s16le 44100hz and I also cannot find a way 
of changing this.

Is there any update on this issue?

satishsampath commented 9 years ago

No updates yet. I haven't had time to work on frameserver so I'm hoping someone else would contribute a patch

nfp0 commented 9 years ago

Aw, that's a shame. Thanks for the support anyway! Any known trick or workaround?

nfp0 commented 5 years ago

Is this fixed in Frameserver 3.0?

wwaag76 commented 5 years ago

No. It stills renders audio at 44.1 Khz.

satishsampath commented 5 years ago

I'll check. Opening it to track.

satishsampath commented 3 years ago

Frameserver 4.0 release has this fix, so marking as closed. From 4.0, Frameserver is now being maintained/developed as trial/commercial software by the folks at www.cumincode.com/frameserver/ .
