    Read Audio TImecode Problem/Question

    Hello,

    I am using a Horita Portable Time-code generator unit with a Tascam HD-P2 audio recorder. For a setup like here on Avid Read Audio tiemcode tutorial with Media Composer.

    http://www.youtube.com/watch?v=U6m1vNTeRso

    I set the Horita unit to 23.98 and tried using the tascam HD-P2 timecode setting as 23.976 but the timecode generating is garbled. I then switch the tascam into 24p and both the Horita and Tascam were both synched.

    I set the Audio to 96,000khz 24bit stereo on the Tascam then it was Jam synched to the Hirota. I then connected the RCA output of the Horita into the Canon 5d mk2 audio mic input. I was recording video 1080p at 24p aka 23.976, with 48,000khz audio.

    I then loaded my audio and video files into Avid Media Composer 5.5.3 trial before I buy. I changed the start timecode in the bin, under duplicate to aux tc1. I then click the Canon MOV file that I imported into AVID as MXF and choose, special, read audio timecode. It reads, on the Broadcast WAV from the Tascam I imported it asks me for the time settings in Avid for the TImecode so i choose 23.98 from the drop down.

    I then highlight the bin and choose autosync, I get the newley created synced clip, it has the correct video and audio, but the audio is around 6-8 secs late? Could the reason be because I had the audio recorder at 96,000khz, 24bit stereo and the audio on the Canon was 48,000khz?

    Thanks,

    Leo

    Try recording on the Tascam at 48khz rather than 96kHz. The sample rate conversion may be playing havoc with the LTC signal.

    hello michael,

    thanks for the reply, any way i can convert the audio maybe in pro tools or another tool to fix this? as i would need to manually sync every shot, yes 48k test works perfect.

    thanks,

    leo

    Why do a sample rate conversion to 48 ? Doesn't it work if you stick to 96K inside Avid?

    OK, I get it, SR conversion from 24 to 23.976, not 96 to 48.
