** I STOPPED MAINTAINING THIS LIST IN LATE 2020. SOME LISTED ISSUES HAVE BEEN FIXED SINCE THAT. MANY REMAIN. SO THE LIST MAY STILL BE OF VALUE AS A REFERENCE. **

------

This is an unofficial list of some issues known to the community in the latest version & build of VEGAS Pro. It is not a comprehensive list.

To be listed below, an issue preferably has to either be acknowledged by MAGIX or verified by a number of users.

Issues that are marked, for example, [VP14+] affect that earlier version and all since it. Some of the issues marked [VP≤13+] also affect versions earlier than VP13.

For issues that are not listed, please comment on a relevant existing post, or the pinned "General Discussion" post for the latest version, or start a new post.

Please message me or another moderator if you believe an issue has been fixed, incorrectly listed, or overlooked.

The Release History post lists issues that have been fixed and new features.

OFFICIAL KNOWN ISSUES

Below are the official known issues listed in the Release Notes at C:/Program Files/VEGAS/VEGAS Pro 18.0/readme/Vegas_readme.htm

• Some video effects may exhibit incorrect behavior when running on NAVI based AMD GPUs.  Turning off GPU acceleration in the Video preferences can allow these effects to run properly.  A future driver update for these GPUs may fix this problem.
• If you are printing a rendered file to HDV tape, the file must precisely conform to the target HDV device and file type requirements, or the print-to-tape operation will fail. Rendering using the provided HDV MPEG-2 render templates—unmodified in any way—is required to successfully print to HDV tape.
• VEGAS Pro templates for rendering multichannel audio in .wav/.wav64, .avi, and .mxf formats may be visible in other VEGAS applications that do not support multichannel audio. Using these templates in other applications will not produce the desired result and should be avoided.
• Under some uncommon conditions on multiprocessor machines, you may encounter stability problems when using some Waves 5.2 plug-ins. In most cases, the stability issues can be resolved by clearing the Enable track buffering check box in VEGAS Pro (Options > Preferences > Audio Device).
• You may not be able to render files larger than 4 GB using some combinations of settings in the Sony AVC encoder.
• If you have multiple VEGAS or MAGIX applications (such as ACID, Sound Forge, CD Architect, etc.) installed, uninstalling other applications may cause your audio plug-ins to be removed from VEGAS Pro. To restore your audio plug-ins, uninstall and reinstall VEGAS Pro.
• When the Show Video Monitor button in the Trimmer window is selected, video that you preview from the VEGAS Explorer and Media Manager windows is played back in the Trimmer. Because the Trimmer is placed in the same window dock as the Explorer and Media Manager, you will not see your video preview. To preview Explorer and Media Manager video, you can drag the Trimmer to a new dock group, or you can turn off the Show Video Monitor button to preview in the Video Preview window.
• The Step Forward and Step Backward buttons in the Capture window are not supported by all HDV devices.
• If your project contains still-image sequences, segmented .r3d files, or P2 MXF files, do not select the Copy media with project check box in the Save As dialog. Some frames or segments may not be saved when this check box is selected.
• Installing driver 2.21 for the PDW-UI XDCAM drive can prevent VEGAS from starting. Uninstalling the driver or upgrading to version 2.3 will resolve the issue.
• If you're running two instances of VEGAS Pro, external control devices are available only to the first instance of the software.
• When using the Stereoscopic 3D Graphic Card as your preview device with an nVidia 3D Vision for Quadro or 3D Vision Pro setup on a Windows Vista machine, the 3D output may stop when opening another window (such as a video FX property page). If this occurs, please make sure you have the latest graphic card driver and 3D Vision USB driver installed. If installing the latest drivers does not fix the problem, try switching the primary and secondary monitors. There is also a known issue where content on the main window will flicker. This can be fixed by moving another window over the portions of the window that are flickering and then closing the overlapping window.
• We recommend Windows 7 for nVidia 3D Vision for Quadro setups.
• Rendering CineForm Neo3D files requires CineForm NeoHD, Neo4K, or Neo3D 5.1 (or newer) or GoPro-CineForm Studio, Studio Premium or Studio Professional. The CineForm Neo Player is not compatible with other CineForm products. Do not install Neo Player if you have another CineForm product installed.
• CEA608 and CEA708 closed captions are supported over HD-SDI on AJA cards only. Line 21 captions are supported on AJA and DeckLink cards.
• Right-clicking a media file and choosing Edit Source Project fails to load the project path saved in the media file for media rendered using the following settings: MainConcept AVC/AAC and Sony AVC (Memory Stick templates only).
• In order for some devices to appear in the Device Explorer window, you may need to change the device’s USB Connect setting from Automatic or MTP to Mass Storage.
• The Tools > Burn Disc > DVD with Menus and Tools > Burn Disc > Blu-ray Disc with Menus commands are unavailable if DVD Architect Pro is not installed.
• If you want to use RAW camera files in your project, the Microsoft Camera Codec Pack will allow you to view RAW camera files and add them to the timeline.
• When previewing through an SDI video preview device, audio and video quality issues may occur when previewing 720p video.
• When using an AJA SDI device, AJA driver version 10.1 is required for audio and video preview. Do not use driver version 10.3.
• For best results when previewing audio through an SDI video preview device, please turn off Video Preview on External Monitor before loading a project or changing project formats.
• 24p pulldown removal is not currently available for Panasonic P2 files.
• Some MOV files recorded by devices running Apple iOS 6 may fail to read correctly when using QuickTime 7.7.2. Updating to QuickTime 7.7.3 resolves the issue.
• When using some source files with highly saturated colors, you may notice color variations after rendering when the Project Properties > Video > Pixel Format is set to 8-bit. Change the setting to 32-bit floating point (video levels) to prevent IRE levels from clipping.
• When using AMD Catalyst 13.4, Video Preview on External Monitor does not work correctly when using a display that is rotated into portrait mode.
• Shot marks are not read correctly when copying DVCAM clips directly from an XDCAM Station. The shot marks are displayed correctly when you use the VEGAS XDCAM Explorer to import clips.
• Only 4:2:0 10-bit HEVC rendering is supported.
• Storyboards do not handle multiple instances of the same media.
• Replacing a piece of media in a storyboard does not replace it on the timeline.
• Using import media function to import media directly main timeline storyboard does not update the main timeline.
• Auto-scrolling does not work within the storyboard.
• Reordering media in the storyboard resets the in/out points to beginning/end.
• Checkerboard artifacts may be visible in HDR external preview when preview quality is set to "Best" with certain kinds of footage; please switch to "Good" quality in such scenarios; this does not affect the actual rendered output
