Decompose, Batch Import, Uprez doubt.

[Satish More] “Is it possible to decompose somehow to form smaller masterclips that are just the length of the subclips+handles?”

Nope. When you batch import it imports the whole clip. Subclipping doesn’t help either, unfortunately.

Thanks Michael,

But don’t you think that it kinda sucks? Like, think of a documentarian, if he/she has 200 hrs of video, it will be a mess to go uprez/online.

But here is something i did.

I did a Consolidate (also transcode) and it formed smaller master clips. And they load in the source monitor and play. Now avid pulled these smaller mxf’s out of the larger mxf’s already on the drive.

I batch imported some of them at DnxHD175x from the original Uncompressed QT files on the external RAID.

But after the import all I see is Pure black. The clips are of the same duration as the original DnxHD36 clips. But there is no video information, Just black. Not even “media offline”.

Another note, It does not seem to access the external RAID while attempting to “import”.

🙂

Does that give you some clue somewhere?

If not, then I will just

Thanks a lot for the help man.

Cheers

Avid is not going to be able to import a part of a file, it will always import the whole thing. This is probably unavoidable really as various formats are stored in different ways, it would be very hard, programatically, to issolate a smaller part of a video clip from a larger file in a reliable way (what works for Animation QT wouldn’t work for H.264 for example).

If you’re working with this sort of material again in the future, then the best workflow would be to import all the media into the ‘online’ resolution, and then transcode that full resolution to a lower resolution for the edit. In this way you could have one hard drive with the low datarate offline footage on it, and one with the full resolution online footage. If you do it that way, then when it comes to making the online all you have to do is relink the offline sequence to the online media.

Alternatively Avid’s recently introduced AMA feature currently provides very fast access to P2 and all XDCAM variants, and may well be expanded to other formats. It provides a very effective way of working with file-based camera formats.

Hey Dylan,

That makes a lot of sense.

Different encoding programs might be hard to decode ans extract from especially on the frame level.

Thanks for the expert answer. I went ahead and imported all my footage in the higher rez yesterday night.

I still think though that they should have a TC support for generic Uncompressed QT files.

And yes, I liked your idea of importing in the higher rez in the first place and then downrezing from there for the edit.

Thanks a lot for your help and support.

I appreciate it.

Thats not true. Every Quicktime based editor does this (FCP, to name one). The problem is that Avid does not read Quicktime’s Timecode track.

Agreed. I just completed an HVX200 HD project where I transcoded the media to DV25 so I could load all of it. From the DV25 I made subclips of my selects and transcoded the subclips to DNx145 and relinked to the DNx files. It worked flawlessly except for one clip that absolutely refused to relink and I had to transcode in its entirety.
