Hi Michael,

Thanks for your reply.

There is a particular workflow where we will be working with DPX files in SD PAL resolution and these files will be sent to different systems for grading, and compositing on the Avid DS.

More questions :

1) Does the Avid DS need to convert the DPX to its internal .gen format before it can work with the files or can it work directly on the DPX files ?

2) Does it render out DPX files as well ?

3) And if it does, will it preserve the metadata information in the DPX headers, such as timecode/keycode ?

Thanks,

Hi Jeremy,

This switcher is a HD-SDI switcher. The Firestore Firewire HDDs only accepts a Firewire signal so I still need to find a device that can take a HD-SDI video signal and convert it to a Firewire signal.

I think probably easiest is to configure a MacPro with a HD-SDI capture card and then capture it as DVCProHD directly to a Firewire drive since the objective is to capture into Firewire drive which would be taken back to the edit studio for editing, as we the switcher is at another location.

I don’t think so since the output is determined by the Video Playback selection in the Audio/Video Settings.

Any reason why you want both to be active at the same time ?

I’ve just setup a Kona3/MacPro/FCP 5.1.2 and I managed to read Cinewave clips (SD/HD) using the Kona 2vuy codec. Nothing specific that needed to be done.

Hey folks…relax man. Everyone take a deep breath and chiiillll….

I’m aware that DVCProHD is not 1920 x 1080 and I’m happy for it to be converted to 1440 x 1080 so that it can travel down the Firewire path and be captured as a DVCProHD clip.

Just trying to figure out what I can use to convert the HD-SDI signal which is coming out from a HD switcher to a Firewire format which I can then feed to a Powerbook. Unless there is a Firewire HDD out there that can capture in DVCProHD format.

Edit in FCP and record to HDCAM. Use EDL Mirror from Digital Heaven to sort the EDL so that the record In/Out timecode is mirrored to the Source In/Out timecode. This way the Nitris operator can digitize off the HDCAM and still have the individual shots in the sequence, rather than a single long clip which he has to manually chop them up.

Hi Wally,

Is your sequence at 1080i ?

For my case, my sequence is at 720p as it was injested that way. I can playback nicely using the AJA Kona2 720p25 video playback selection but the AJ-HD1400 VTR doesn’t record in 720p25, only 720p50 but I can’t get FCP to playback 720p50 via the Kona 2 although there is a 720p50 video playback selection there.

Right now the only way I can lay the 720p60 @ 25fps sequence to the AJ-HD1400 VTR is by setting it to 59/60 system frequency but the timecode then becomes 29.97fps. Visually it looks ok but because of the 29.97fps timecode I cannot easily make a 625i PAL downconvert dub without first doing a 525i NTSC downconvert dub and then do a standards conversion.

Probably best to upconvert on the VTR itself to 1080i but then for those variable frame rate shots, it has to be injested at 720p inorder to get the fast/slow motion. Do you know if the variable frame flags are lost if we upconvert on the VTR ?

Bob…don’t forget speech recognition as well…:P

Hi,

Yes I did notice the 1440 x 540 display size on the slow motion clips. They did actually look less sharper than the normal clips.

Thanks,

All PAL frame rate and resolution is also missing in the list.
