Vegas Pro Freezes Up

Harley-Piltingsrud wrote on 1/7/2024, 3:52 PM

I have been using Vegas Pro for many years, recently version 21. When I record 8 track audio files 96 kH, 24 Bit for long periods (over 2h) it freezes up with around 24GB in the recorded file, even with 400 GB remaining space in that file. I have tried many things in troubleshooting, but no luck. When it freezes up there is no error message. It seems the program is corrupted. I reboot to get it working again.

If I was to guess, I would say buffer underflow. What audio drivers have you chosen in Vegas, are they up to date, and what are the encoder settings?

In Windows a single WAV file size is limited to 4GB... perhaps you are hitting that wall?

for example, a 24bit 96kHz Stereo WAV file 2 hours long, will be uncompressed filesize: 4.15GB

@Harley-Piltingsrud W64 uses a 64-bit integer to represent the file size in the header. That gets it past WAV format which uses 32-bit there and cannot express a number larger than 4gb. If you can record w64, Vegas reads it fine. If your recorder cannot write out a proper w64 file, a workaround might be to set it to record a mono track for each channel. For compatibility with Sound Forge 7, which supports w64 but only up to 2 channels, I do that regularly recording 8-channel with my Sound Devices 788T.

Thank you for your suggestions. I am using Windows 10 Pro, 64 bit with i7-7700k 4.26 MHz processor and 8 GB ram, with an ASUSZ170-AR motherboard. I use a 8 channel Focusrite Saphire A to D with a Firewire connection to the computer. The up-to-date Saphire Mix Control has a Firewire Driver Latency set as "Very Long" and an ASIO buffer size of 2048. Vegas has enabled track buffering of 1.225 s. It is set for automatic detect & offset hardware record latency. I was getting somewhat random freezes of Vegas recording 4 stereo tracks 96 kH, 24 B for over 1.5 h. After updating the updating the motherboard BIOS I now get dependable recording to 3h, 4 min when Vegas freezes. The files are all in Sony .w64 format, so file size shouldn't be an issue. However, there is a lot of detail in the computer and software parts of this I don't understand.
