  Using DVCPRO50 with AJA IO ???

  Posted by Todd Miro on July 1, 2006 at 5:51 am

  So I have a new FCP system with AJA IO LA and a SATA striped array running off a new Dual 2.3Ghz G5. I tested the 8 bit and 10 bit uncompressed output and everything plays back fine. However, when I try to set up a DVCPRO50 test something’s not right.

  First I set my sequence to 720 x 486 29.97 fps DVCPRO50-NTSC. Then I render out a test from After Effects to the same exact specs- 720 x 486 29.97 fps DVCPRO50-NTSC. I look at the browser info in the bin for both the sequence and the file that I import and even though they are identical, when I place the clip in the sequence, the red line shows up above it indicating that I need to render it. And then, even if I render it, it won’t send any video through the AJA IO so I can monitor it on NTSC- I just get a static image. I’m setting my Video Playback to ProIO-NTSC US Component RGB -8-bit 720×486 which works fine for 8-bit or even 10-bit sequences.

  Now the AJA IO Guide states, “…you can use IO to convert DV50 projects to uncompressed-in real time-for monitoring and/or output.” So what am I missing? I’d really like to work in DV50 for some projects to save drive space.

  Thanks,

  Todd

  hi todd –
  here is what I would like you to do. Remember when you tested out your system with 8 bit and 10 bit uncompressed – you probably went into EASY SETUP and selected something like Betacam 8 bit uncompressed, and everything worked. Right ?

  Go into EASY SETUP, and select NTSC Betacam to DVCPro50 (or DV50, I am not in front of a system right now). Then, delete your current sequence, and open up a new sequence. Double click on it so it opens up. It will now be a DV50 (DVCPro50) sequence. Digitize away – I bet it works.

  Working in DV50 is teriffic.

  Todd,

  DV50 is not 720×486 it is 720×480 same as dv.

  Thanks guys, the 720×480 was it- I figured it was something obvious I was missing.

  Bob makes a good point. The AJA easy setups are usually the best way to go when choosing a format. AJA has already done all the work for you.
