Re: [Avid-L2] Media Composer for reality shows

 

Marian,

     I just finished posting a performance series for PBS where we recorded many long continuous clips of 4 hours 49 minutes each, using multiple Cinedeck MX machines recording DNxHD 145 in MXF OP-Atom wrappers, including 4 channels of audio per clip.  All our clips play flawlessly on multiple Avid MC 7.0.4 systems running on a Windows 7, on hardware ranging from a Dell quad-core i7 laptop to an HP Z800 dual hex-core Xeon machine.

     And after reading your post I just strung together 3 clips of 04:49:00 each and, as you noted, I couldn't play the audio.  But then I went back and cut shorter clips together into a sequence of 13 hours 20 minutes and the audio plays fine.  (HP Z400, Win7, MC 7.0.4).  

     So yeah, I did replicate at least one of your bugs.  But I can play clips of over 4 hours, and a sequence of over 12 hours, with audio. 

     Cheers from snowy Boston,
     Wilson Chao

Hello everyone
One of our customers just begun production of a reality show, where they film some folks around the day.. something like BigBrother. They are using MC with interplay to edit the material but we've hit some limits that makes the editors life very hard :
1. They use "Autosequence" to line up in sequence all the clips, recorded with time of the day as TC. That is a nice feature, but unfortunately those sequences cannot be used in a multicam group. We;ve tried the "Autosync" on those sequences to create a subclip, but it;s not working since there are edits in it. (not sure what edits are, since there is no cuts, trims etc)
As a workaround you must do videomix downs on those clips, but this is insane since the it takes a lot (they have 8 or 9 cameras, and the resulting clips are around 18 h per day.
Is there any other way that you can use those sequences for multicam? I
Is it true that Premiere can do it?
2. Seems that we've hit a bug where sound records longer that 4 hours are not played in MC, Import is fine, but you cannot get any audio out of MC. Waveform is also blank. As a result you need to split the audio in smaller files
3. Initially they planned to have one sequence per day where they can have all the material in. But we've hit 2 limitations: If a sequence is longer than 12 h, you will not get any audio out, even if waveform is there. You need to split the sequence to monitor audio tracks. Also you cannot have more than 24 audio tracks, in MC 7. or 8. In MC 5 you can have more that 24, but only 24 active

How do people deal with those limits? I would assume that others hit those issues before us.. maybe they have a solution
Thanks
Marian B
