    Hi

    I’m undergoing a change of technique and could do with a little advice. I make TV commercials. Up till a year or so I’ve been shooting on 35mm, transferring to tape for off-line on my own Express Pro HD system and then taking the project files into an on-line house for finishing. It works fine. Last year ago I started working on HD – specifically the Sony 750 and Panasonic Varicam systems at 25p. I used the same technique except now the transfer process seemed a little unneccessary cumbersome and the fact that I was staying in DV all the way through the process seemed to offer me more in-house opportunities creatively. So I tried it the other way around. Instead of copying my rushes to DV tape(I have one of those Sony portble HDV decks) I went into a suite and digitised all my rushes at 1:1 straight to a hard drive – with the intention of keeping the whole project in one place – only using the final facility for grading and legalizing and final playout to tape. Unfortunately I couldn’t get the Avid Express Pro to read the files – even with a (borrowed) Mojo – although I have to admit I have no idea whether the configuration was right!

    It seems to me it ought to work fine. I’d like to do it so that I can keep everything uncompressed and get my rushes into After Effects that way. I have a purpose built PC with all the bells and whistles so the hardware isn’t a problem.

    Any help you can offer would be greatly appreciated.

    Thanks

    Bill

    When you say you can’t read the files…does the express pro see any media on the drive? Were you loading omf or mxf on the other system? The mojo shouldn’t make any differance if the media is already digitised. Will the express pro work at non dv resolutions?

    The answer maybe a slightly differant workflow…

    Load uncompressedd 1:1 on nitris or similar, then transcode the files to an express acceptable format without delting the origionals (two seperate drives would simplify this method)…make your offline cut then when you return to your post house for grading relink the sequence to the 1:1 media.

    Thanks for this – the transcode idea is a good one. Hadn’t thought of that. Avid Express could see the media – just labelled it in compatible format – but I thought it could read 1:1

    You should definitely be able to see your footage in Xpress Pro HD–what version are you running?

    Another thought about transcoding–are you renting time to capture everything at 1:1 at your online house? If you are, do that then take it home. No reason to pay for the extra time to transcode there. Hook up your drive to your Xpress Pro HD and do your transcode at home, consolidating and transcoding the files off the hard drive to your media drives on your own system. While transcoding doesn’t typically take long, there’s no reason to pay for that time at your online house when you can do it on your own system on your own time.

    Also, I’m curious as to why your system doesn’t let you play your 1:1, especially with a mojo. If you want to solve that little problem post exactly what your configuration was, as well as your system specs and the version of Xpress Pro HD you’re running. We’ll try to get you up and running so you can skip the transcode alltogether.

    Mike.

    probably does only dv reses though I’m not that familiar, the transcode idea should make sense, the only drawback is that you may need to re import any ae type stuff at the grading stage. Relinking at the final styage is a tried and tested method, I’d still keep the express stuff as at high a res as it will handle.

    Thanks for this – sorry I didn’t get back sooner – been away. I think I’m running the most recent Xpress Pro 5.2.4, upgraded it around march – on dual opteron 250s with 3gig Ram and a Tyan Thunder board. nVidia quatro card and three separate 1394 cards.

    The edit house digitised the media at 1:1 via Adrenaline on to a Lacie and I brought it home and pluggede it in. Avid saw it was there but said it was unsupported and I should transcode it. So I tried that but it didn’t happen – I’m not sure now what the problem was. Anyway, I ran out of time and went back to digitising the rushes via the DV clones I’d had made in case of such an eventuality. I think the mojo was a red herring – as I understand it its main use would be in playback to a monitor – which I don’t use anyway…

    I have a big shoot starting in 10 days and I’ve been looking at buying a firestore – but I’m not suree if it digitises at 1:1.

    Any advice would help and be appreciated.

    Thanks

    Hi

    I also work in commercials….when we do a shoot on 35mm or Panasonic Varicam, HD etc. we always transfer the rushes onto SD with MATCHING TC. We load the SD rushes into the offline suite and then conform the HD rushes with MATCHING TC into online machine, and log our rushes identically (Rubber Banded) together into the same database…..IT WORKS FOR US.
