File I/O Tab

Item	Description
Enable auto-detection of 360° media	When this checkbox is selected, VEGAS Pro will recognize 360° media when loaded and sets the project properties to 360° output automatically.
Render large Wave files as Wave64	The .wav format is limited by a maximum file size of ~2GB (4GB if the Allow Wave renders up to 4 GB checkbox is selected). When this checkbox is selected, you can render larger files as Wave64 files.
Allow Wave renders up to 4 GB	Select this checkbox to enable support for WAV files up to 4GB before switching to WAV64. Clear the checkbox for compatibility with other software applications.
Ignore fact chunk when opening compressed WAV files	When this checkbox is selected, VEGAS Pro will ignore fact chunks in compressed WAV files. Compressed WAV files use fact chunks to specify how many actual samples are represented in the file. If a compressed file is improperly authored, this may cause some of the compressed data to not be loaded. If you suspect that not all sound data is being loaded from a compressed file, try checking this option and reopening the file. TIP If you change the setting of this check box, please delete any proxy (.sfap0) files associated with compressed WAV files.
Import MXF as multichannel	Select this checkbox if you want to import MXF files from XDCAM cameras and decks with multichannel audio. When the checkbox is cleared, audio from MXF files will be imported as stereo.
Enable no-recompress rendering	Select this checkbox if you want to pass through unedited frames without recompression (smart render) for the following formats: DV AVI DV MXF IMX MXF (IMX 24p MXF is not supported for no-recompress rendering) XAVC Intra MXF HD MXF MPEG-2 (for files such as those from HDV and DVD camcorders) Panasonic P2 For more information, see Working with P2 Video XDCAM EX supports smart rendering across the following formats: SP 18.3 Mbps CBR 1280x720p to/from XDCAM EX and HDV HD-1 SP 25 Mbps CBR 1440x1080i to/from XDCAM EX, XDCAM HD, and HDV HD-2 HQ 35 Mbps VBR 1440x1080 to/from XDCAM EX and XDCAM HD HQ 35 Mbps VBR 1280x720p to/from XDCAM EX HQ 35 Mbps VBR 1920x1080 to/from XDCAM EX In order to perform rendering without recompression, the width, height, frame rate, field order, profile, level, and bit rate of the source media, project settings, and rendering template must match. Frames that have effects, compositing, or transitions applied will be rendered.
Enable QSV Encoding and Decoding (where available)	This option turns on Intel Quick Sync Video (QSV) hardware acceleration for encoding and decoding, where supported.
Enable OpenCL/GL Interop for Intel GPU	When checked, this enables the interoperability between OpenGL and the Graphics Library for Intel GPUs for improved performance.
Enable direct GPU import path	If this is enabled, VEGAS Pro will use a direct path to import media using the GPU, which can improve performance for GPU-accelerated formats.
Favor audio sync when playing Variable Frame rate (VFR) media	This setting, when checked, prioritizes keeping audio in sync over maintaining smooth video playback when playing media with variable frame rates.
Enable Hardware Decoding for supported formats	This checkbox switches hardware decoding of AVC/HEVC media on and off, where applicable. Select the Hardware Decoder (NVIDIA NVDEC or Intel QSV) to use in the list box below. Hardware decoding works only, when the right hardware is available and the media is suitable for hardware decoding.
Enable MKV Reader (experimental)	Activates the new, experimental file reader for the .mkv Matroska video format, a free and open source video format. For more information, see mastroska.org.
RAW Processor	Specify the device you want to use for RAW processing. This delinks the RAW processing accelerator from the video processing accelerator and enables you to specify the best option for both of them. This is especially useful to you if you have multiple GPUs in your system because you can spread the processing work between two of them. This gives you higher overall GPU utilization and access to more processing power.
Log Plugin loading/Reads/Renders	In case you have technical problems with your VEGAS Pro project you can get a log file when checking these options. Even if you don't understand each and every entry of the log file it can help you to identify problematic media files or plug-ins in your project. It is possible to log the loading process of plug-ins and media files and the render process. To activate logging, switch the according list box from Off to Basic, or for a more detailed logging to Detailed. The Log files can also be helpful for the technical support to identify problems. You find the Log files in c:\Users\[username]\AppData\Local\VEGAS Pro\22.0\, they are normal text files with the file extension .log
