When using Time of Day (Clock) time the time code should be Drop Frame. I suspect there are time code flag issues in the meta data. I spotted a what I now think is a related problem while shooting 1080p30 using Clock time. Michael, I’m hearing others are having the problem. I have plenty of files that I’m going to capture using the camera HD-SDI into my Kona LHe the old fashion way. For now I won’t be shooting HQ 720 24p anytime soon.

I can view the clips in the Clip Browser so I’m hoping this is a software bug. The error is “There is no timecode calculator in timecode track builder” when importing the clips into the XD Cam Transfer 2.1 program, the clip then say “No Image Available” and you can’t move them into the viewer. As I said the only common thread here is the HQ 720 24p format, Sony’s Ian Cook didn’t have anymore answers for me or the other person who has this issue. Sony also said I could try deleting and reinstalling the XD Cam transfer software.
The only bit of advice was to trash the .plist, and that didn’t seem to help. Sony will push this up to the software department that wrote the transfer program as well as on to Japan. I have been asked for some XML files from each BPAV file. It seems 720 24p is the common denominator. Monnaie #0.00 € -#0.Well I spoke to Sony today and it seems there is someone else with this same issue. Les documents et les spécifications techniques SMPTE, y compris celles référencées dans ce document, sont disponibles sur To modify the timecode of a Broadcast WAVE file to drop frame:ġ - In the Browser, select the audio clip whose timecode you want to modify.Ģ - Choisissez Modifier > Timecode, puis choisissez Drop Frame à partir du menu local Format.

Instead, Final Cut Pro 5.1.2 always calculates non-drop frame timecode for Broadcast Wave files. Although there are several de facto ways this information is stored, Final Cut Pro 5.1.2 does not support reading this information. There is no ratified standard to indicate or detect whether a Broadcast Wave file was recorded with drop frame or non-drop frame timecode. When the sequence preset frame rate is 29.97 fps and the sample rate of the Broadcast Wave file is defined in the SMPTE specification, Final Cut Pro uses the repeating frame patterned defined in the SMPTE specification.įor more information, see sections 3.15 and 14.3 of ANSI/SMPTE 272M-1994 "Formatting AES/EBU Audio and Auxiliary Data into Digital Video Ancillary Data Space."ģ - Dropframe indicators in Broadcast Wave files: The audio sample rate of the imported Broadcast Wave file The time base (frame rate) of the currently selected sequence preset When you import a Broadcast Wave file, Final Cut Pro calculates timecode based on two parameters: Instead of an exact number of samples per frame, a consistent pattern of varying samples is spread over several frames. The number of audio samples per frame is varied on a frame-by-frame basis to form a consistent pattern. To avoid ambiguity, the Society of Motion Pictures and Television Engineers (SMPTE) specifies how many audio samples should be mapped to each video frame. However, with NTSC-related video rates, there is no simple relationship between the number of audio samples per second and video frames per second. For example, if the audio sample rate is 48000 Hz and the video rate is 25 fps, every 1920 audio samples is equivalent to one video frame. When the sample rate is an integer multiple of the video frame rate, the timecode count can be accurately mapped to the sample count. Timecode is calculated for digital audio files by mapping a certain number of audio samples to each video frame. Final Cut Pro uses the more accurate calculation (30 * 1000/1001).įor more information, see SMPTE 170M-1999 "Composite Analog Video Signal - NTSC for Studio Applications."Ģ - Mapping audio samples to video frames: Timecode calculated using 29.97 (instead of 30 * 1000/1001) can be inaccurate, especially as the duration of media increases. Calculating timecode for NTSC video is complicated because it's true frame rate is not simply 30, nor is it 29.97.
Timecode calculation is fairly straightforward, with the exception of NTSC-related frame rates. In Final Cut Pro, there are three factors that affect the calculated timecode value of an imported Broadcast Wave file: The following section explains how Final Cut Pro accurately calculates time when importing Broadcast Wave files. If you import the same Broadcast Wave file (BWF) into Final Cut Pro and other editing applications, certain timecode numbers may be calculated differently.
