Working with .DV Files Captured on a Mac Inside of Premiere Pro on Windows PC

I have 11 two-hour long .DV files captured from Hi8 tapes using iMovie. These represent the digital masters, and they weigh in at approximately 13GB per hour.

The digital masters are stored on my FreeNAS file server. The capturing was performed on my MacBook Pro two and a half years ago. The computer that I would like to use for editing is my Cool ‘n’ Quiet AMD workstation, running Windows 7 64-bit. Alternatively, I can edit on my MacBook Air.

These .DV files are not natively supported within Adobe Premiere Pro CC (2014 release) on the PC, but they can be imported into Adobe Premiere Pro CS6 on my MacBook Air.

The software that I’m using to make this move away from iMovie and into Adobe Premiere Pro:

  • QuickTime Player 7 Pro
  • MPEG Streamclip

MPEG Streamclip gives the following information about my .DV files:
Video: DV/DVCPRO – NTSC, 720 x 480, 4:3, 29.97 fps, 28.77 Mbps
Audio: DV stereo, 32 kHz, 28.77 Mbps

VLC gives the following information about the same files:
Video: DV Video (dv)
Audio: PCM S16 LE (s16l)

My first effort used QuickTime Player 7 Pro to trim the .DV files into individual clips. I marked the start and endpoints, and selected Save As… (⌘S) Save as a reference movie.

These .MOV reference movies import successfully to my Adobe Premiere Pro projects, with the exclusion of the audio track.

When I use Adobe Premiere Pro to inspect the imported .MOV reference movie, I see that it contains both the video and audio tracks. The compressor on the audio track is vdva.

This error message prints when I attempt to play the .MOV reference movie in VLC:

Codec not supported
VLC could not decode the format "dvau" (DV Audio)

I see several possible solutions:

Extract the audio track separately, export the .DV into another file format for editing, locate the “dvau” codec

Going back to the iLife suite is not an option.

Within QuickTime Player 7 Pro, I can select Save As… Save as a self-contained movie to save the .DV as a .MOV, but at the expense of doubling the file size. Holding onto this .MOV and the original digital master would result in massive disk usage.


It turns out that no elaborate workaround was needed. The obvious problem was that my Windows machine lacked the codecs required to work with the .DV files that I made using my Mac. I downloaded and installed QuickTime 7.7.8 for Windows 7 (Apple), and was able to work with the files just fine.

Hopefully this helps!

How to Enable Dolby Digital on Realtek PC Optical Output

When I acquired the Turtle Beach EarForce DSS, it saw duty with the Xbox One, where I encountered no difficulty configuring the optical output to Dolby Digital. Its service life there was limited, however, because it didn’t play nicely with my headset configuration. Try as I might, there was no easy way to get party chat sounds to play through the Xbox One’s optical output, a limitation that didn’t exist with previous generations of the Xbox.

I moved to use the Turtle Beach EarForce DSS with my workstation computer, which features an optical audio output from the motherboard, powered by Realtek.

I was able to accomplish this through the use of unlocked Realtek drivers. Here’s the discussion about this topic on TechPowerUp’s community forums:

Download Realtek High Definition Audio – Unlocked Drivers – Windows 7 – R2.75 – A1 from Unlocked Realtek HD Audio Drivers (With Dolby Digital Live and DTS Interactive)
Download Realtek High Definition Audio codecs from Realtek website (R2.79, current at time of writing)

To enable Dolby Digital output, I performed the following:

Installed Realtek High Definition audio codecs from Realtek website

Renamed C:\Windows\System32\RltkAPO64.dll to RltkAPO64.dll.bak

Copied RltkAPO64.dll from the unlocked drivers archive

Opened Regedit and created a new DWORD (32-bit) in HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Audio named DisableProtectedAudioDG and set it to 1.

After restarting the machine, new options became available in the Realtek HD Audio Manager under Digital Output: Dolby Home Theater & Dolby / DTS. I was able to get the optical output to output a signal that the EarForce DSS picked up as Dolby Digital by setting the default format to Dolby Digital Live (5.1 Surround)

Most recently, I’ve noticed that Realtek HD Audio Manager is no longer present. If you don’t have Realtek HD Audio Manager, right-click on the speaker icon in the taskbar, click Playback devices and view Properties for Realtek Digital Output. Under the Advanced tab, you should now find Dolby Digital Live and DTS Interactive within the Default Format dropdown menu.

If all else fails, pick up an ASUS Xonar U7 USB sound card, and plug and play.
