the 50mb files aren't supported. Yet.
You are probably trying to import IMX50 files. Premiere Pro does not natively support IMX50 files. Not officially anyway. The only XDCAM file format officially supported and known to work (my own experience and after a long support ticket discussion with an adobe technician) is DVCAM. The only official way to edit IMX50 files is by using a hardware dedicated card like the Matrox Axxio card. The drivers supplied by that card enable premiere to load, play and edit IMX50 files that are encapsulated in MXF files.
However, all is not lost. We did figure out that when you rename the .mxf file with IMX50 structure to .avi, Premiere opens the file and is able to play back. However I am not sure and will not assure you that this will be a stable editing environment. You might get crashes during editing these files. I just don't know. We decided to buy a Matrox Axxio. Not one of our brightest ideas since it doesn't always work falwlessly ...

That's a little confusing. XDCAM EX and DVCAM are two very different formats. The first is HD, the latter is SD. One is MPEG based, the other is basically DV.
It's also my understanding that the XDCAM cameras don't even shoot in SD, only HD. What say you?
No, he's correct; I think Alex is referring to XDCAM (disc-based) and not XDCAM EX. All of the XDCAM cameras--both the SD and HD models--will shoot to DVCAM, as well as other SD and HD formats. When referring to "DVCAM" in this case, it's an allusion to Sony's "brand" of DV, and not necessarily DVCAM tape. Any format the XDCAM cameras record is stored as MXF files on to an XDCAM optical disc. Check out the various camera specs right here.
Alex: I think the only reason you can "kinda" get the IMX50 clips to work when renaming them with an AVI extension is because you do have Axio. Premiere Pro, right out of the box, doesn't have IMX50 playback capability, so I imagine that the drivers/codecs you have installed from Matrox are enabling that, presumably in a non-Matrox project, as well. That would be my guess, anyway.
I am indeed referring to our PDW530p camera which is a disc-based (PDF23a Sony, bluray-like, discs) camera that saves every shot in a MXF file, no matter what format is used. I probably made it more confusing then necessary. Basically you can shoot to DVCAM and that is a format Premiere can natively import. IMX50, which is XDCAM as far as I am told, can not be imported by premiere natively.
@colin: we tried this "trick" (I am now in doubt if we renamed to .avi or to .mpg, it was a while back) on a machine that has a RT.X2 which does not support IMX50 and we NEEDED to be able to either convert or edit the clips. We have two systems here, one with the Axio and one with the RT.X2 (I know, I know :( ). We eventually ended up going to the Axio system, imported the footage in CS3, converted it to something premiere natively does support, transported that over the network to the other machine and loaded it in.
But we WERE able to get the clips in premiere on the RT.X2 system by renaming the clips. We just did not trust it. Feel free to try it if you wish. :)
On the Axio machine you can indeed playback IMX50 recored clips/footage in any program thanks to the hardware, drivers and codecs (it is a joined accomplishment *cough*) Matrox provides for their boards.

Makes more sense. Thanks.

According to Sony, the EX1 and 3 do not.
1920 x 1080/59.94i/29.97P/23.98P
1280 x 720/59.94P/29.97P/23.98P
1440 x 1080/59.94i
There are a number of different formats:
XDCAM-HD, used with either 35 or 50 Mb rates (1440x1080) and
XDCAM-EX used solely on the EX1 and EX3 with 35 Mb rates at full HD.
Both formats have different flavors (29.97/25/24 fps and different compression rates HQ/SQ/LQ, and different resolutions, apart from over/undercranking).
Yeah, I get all that. I was just saying that the hand held EX1 and 3 will only record at HD resolutions. The DVCAM comment threw me till I found out a shoulder mounted XDCAM was being discussed.
