Video files with a lower resolution will also consume less memory. from full-HD to 720p) also helps to increase the playback performance if necessary, especially on older systems. Note that lowering the video resolution (e.g. Use for example, Apple Compressor (OSX) or XMedia Recode (Windows) to re-encode to the Apple ProRes or Photo-JPEG codec (using the. In case your client is not aware of the above recommendations you should re-encode the video with a suitable codec and settings. What can I do if the video file (that my client has sent me) performs poorly within Nuendo? If you are using a lot of different video files in a single project, be sure to run the 64-bit version of Nuendo 6.5.20 (Cubase 7.5.20) or higher. If you import too many different video files, the video decoder’s memory limit will be exceeded and the video engine will stop working. Note that every video file makes Nuendo allocate a certain amount of memory. When using ProRes, DNxHD or Photo-JPEG encoded videos you can import an even larger amount. With the above parameter recommendations taken into account, you can import at least 20 different video files (with full-HD resolution) into a single project. How many video files can be used within a single Nuendo project? Furthermore, if you want your video to smoothly follow when winding or using a jogwheel, make sure to use a key frame interval (IDR) of 1 frame (thus every frame is encoded separately).To keep Nuendo’s performance up, it is very important to: The number of reference frames should not be higher than 2.Anything above will lead to an unreasonably high amount of memory allocation. The number of B-frames should not be higher than 3.However, since the number of video tools that allow for H.264 export is high, and the H.264 specification includes various encoding parameters, you should take care of the following settings when creating H.264 video files: H.264 encoder presets, as offered in current versions of Apple Final Cut, Apple Compressor, Avid Media Composer or Grass Valley EDIUS Pro, usually result in video files suitable for Nuendo. How to encode H.264 video to work best with Nuendo? The problem usually lies in the variety of encoding parameters which can heavily affect the performance of Nuendo. H.264, also known as MPEG-4 AVC (Advanced Video Coding) allows for small video file sizes but can only be recommended if encoded properly. Note that videos using the above mentioned codecs have a rather large file size. Photo-JPEG and Motion-JPEG are working fine too but use single-threaded decoding only. If you are working with DNxHD encoded videos, make sure to download and install the free Avid Codecs LE package. They are also economical in terms of allocated memory per video file. Video files that have been encoded with these codecs play back correctly and run smooth when winding or using the jogwheel. ![]() If file size is not an issue, the ideal choice is an editing codec like ProRes (native format of Apple Final Cut Pro) or DNxHD (Avid's native format). ![]() What sort of video codecs can be recommended for use with Nuendo? Your graphics card needs to support OpenGL 2.0 or higher and it’s recommended to have the latest graphics drivers installed. If you are on a Mac, all needed QuickTime components are already in place. If you are using Windows, make sure to have QuickTime installed (v7.1 or higher). Thus, if the QuickTime Player can play back your video, Nuendo can play it back, too. Theoretically, all files that are supported by QuickTime are compatible with Nuendo. The video playback of Nuendo and Cubase (below, only Nuendo will be mentioned) is based on Apple’s QuickTime engine on both Mac and Windows. ![]() ![]() Entre otras diferencias con el anterior, dicho motor de vídeo ya no depende de la tecnología QuickTime de Apple. Con Nuendo 8 y Cubase 9.0.30 un nuevo motor de vídeo ha sido introducido. Ten presente que este artículo habla de versiones anteriores de Cubase y Nuendo.
