  Adobe Premiere Pro DV audio distortion

  Posted by Laszlo Suto on January 25, 2010 at 12:04 pm

  I have Adobe Premiere CS2 and some audio distortion problems. I captured a footage from my Sony DV Digital-8 camcorder. It’s a standard DV footage with 16-bit PCM audio. When audio is nearly-peaking (not peaking), it gets distorted in Premiere, but doesn’t in other applications (VirtualDub, Media Player Classic, Windows Media Player, mplayer). I’m sure this is because an internal conversion (called conforming) from 16-bit PCM to 32-bit floating point PCM. Project Setting of the Audio Track is 48000 32bit – Stereo for a DV project, despites DV standard supports 16 or 12 bit Audio tracks. In user manual they write the following:

  “For maximum editing performance and audio quality, Adobe Premiere Pro processes each audio channel, including audio channels in video clips, as 32‑bit floating‑point data at the project’s sample rate. To do this it must conform certain types of audio to match the 32-bit format and the project sample rate.”

  Well, if I’m a professional video editor, I believe I can (and have the right to) decide whether which sample rate and bit-depth are the best for me, but they don’t let me set audio format other than the default, there is no option for bit-depth available not even when creating a NEW project. No problem if Adobe’s “genius” developers thought 32-bit mixing provides much more quality, but if they forget to implement 16-bit to 32-bit internal conversion correctly, please let me decide to use at least a fallback method. I find this kind of disgusting at a $800 software, while free open-source video-editing softwares (like VirtualDub) provide much more options for audio formats. Before you ask, No, I don’t want to use VirtualDub for my VE work.

  Thanks for your help

  I use CS3 with Matrox RT.X2, so maybe Matrox added this feature, not sure if it works without Matrox, but in my Settings > Playback Settings, I can uncheck the “Conform Audio” checkbox. Maybe you can turn it off in CS2 as well?
