NUENDO Working with film transfers 111 5.The remaining film frames are transferred in this manner, alternating between 2 and 3 fields of video, until the end of the transfer. After four frames of film have been transferred this way, an even five video frames will be created. Over the course of one second, 24 frames of film and 30 frames of video will have gone by. Since they are running at -0.1%, the actual framerate is 29.97 video frames per second, the NTSC standard. It is important to have a...

NUENDO 112 Working with film transfers Compensating for film transfers to video When working with film transfers to video, it is necessary to compen- sate for the change in speed that results from the telecine process. With Nuendo, there are two basic ways this can be done. The first is by adjusting the playback speed of the audio to match the speed of the video. The second is to adjust the speed of the video file to match the original speed of the film and production audio in Nuendo. Adjusting...

NUENDO Working with film transfers 113 Please refer to the Timebase manual for more information on how to connect it to Nuendo, your audio card, video tape machines and other equipment in your studio. Varispeed operations are also covered in the TImebase manual. Since the video and audio playback speeds are independent in Nu- endo, the video will remain at the same speed while the audio is slowed down (pulled down). This will ensure that the production audio and film transfer will remain in sync....

NUENDO 114 Working with film transfers Audio Pull-up +4.1667% (PAL/SECAM) Audio pull-up (+4.1667%) is the same concept applied to PAL/SE- CAM video transfers. Since the film is sped up by 4.1667% during transfer, audio in Nuendo must be running at +4.1667% speed in order to remain in sync with the video during editing and mixing. In this case, the Timebase or other external clock must be set to +4% varispeed. Devices such as the Rosendahl Nanosync are capable of varispeed and have presets for the...

NUENDO Working with film transfers 115 •Other pull-up/pull-down options There may be other scenarios where non-standard pull-ups and pull-downs can be used to correct mistakes. Nuendo provides further pull-up/pull-down options for such situations in the Project Setup dialog (see below). All the examples used here are with 48 kHz as the standard sample rate for the film and video industry. However, it is possible to accomplish the same tasks using 44.1 kHz, 88.2 kHz, 96 kHz (this is double the stan-...

NUENDO 116 Working with film transfers Nuendo provides an adjustment of the timeline to compensate for these changes. This setting is found in the Project Setup dialog: The Pull-up/Pull-down pop-up menu in the Project Setup dialog. Whenever you apply an audio pull to Nuendo from an external clock, you should also set this menu to the appropriate choice. This allows Nuendo to recalculate the sample count to reflect the adjusted sam- ple rate. For example, if the setting in the Project Setup dialog is...

NUENDO Working with film transfers 117 Moving events When you change the setting in the Pull-up/Pull-down pop-up menu and there are events already in the timeline, Nuendo prompts you to choose whether or not to keep the original sample start times or not. • Choosing “No” allows events to follow the timecode and minutes:seconds clock change and remain at their SMPTE start times. • Choosing “Yes” forces Nuendo to leave events at the same sample start time regardless of the clock speed change. Video...

NUENDO 118 Working with film transfers Video +0.1% pull-up for NTSC Since NTSC video is running -0.1% slower than the original film, pull- ing the video speed back up by +0.1%, returns it to original film speed. With the video now running at the correct film speed, audio originally recorded at 48 kHz on the film shoot will remain in sync with the video. Additionally, the final mix can be digitally transferred back to film at 48 kHz without the need for an analog copy or sample rate conversion. Video...

NUENDO Working with film transfers 119 • Speeding up or slowing down the video speed is only possible if the video is running through a “computer graphics card”. If a professional genlocked video card is used, the video playback speed is derived from the genlock input. What is 23.976 fps used for? The world of digital video formats is ever changing and the results are new developments for every media professional involved in movies, television, corporate video and more. With the advent of HD...
