There’s a couple of ways I know about to bring EX1 files into Avid. Method 1 is to use the clip browser software provided with the EX1 to unwrap the mp4 file on the SxS card and rewrap it as an mxf file. The mxf file can then be imported into Avid.Once imported, transcode to DNxHD.
Method 2(my choice) is to transcode the native mp4 file on the SxS card to cineform intermediate with NeoHD. This method does not require transcoding within Avid. -

Regardless of the workflow, whether it is cineform or sony’s clip browser rewrapping in mxf format, the imported footage will show no degradation in making the change. “transcoding” isn’t really what’s happening with the clip browser, it’s just re-packaging the data in a format that Vegas can understand. Cineform is, in fact, transcoding. However, there are advantages to transcoding to an intraframe compression scheme like Cineform’s.
These days, with fast processors, editting in Long form GOP(that’s what mxf is) isn’t as tedious as it used to be. Nevertheless, the mxf format( really a variant on MPEG2)isn’t designed to edit, only to capture and store. Editting mpeg2 takes a lot of processor power, has problems with I-frame and IGOP sequencing, and is generationally destructive. Cineform’s intermediate codec has none of these problems, is functional across platforms(MAC or PC) and is, for all intents and purposes, very robust.The only disadvantage is the cost of purchasing a license.
BTW, I have no connection with Cineform, I just like their product.

well, that’s not precisely true. Once you run the native EX1 format thru the Sony Clip Browser software(which ships with the EX1) you can then load the derived mxf files into vegas. IMHO, a much better way is to transcode the native EX1 files with Cineform Neo HD, then import the CFHD into Vegas.
It is rather odd that other NLE’s , like Canopus Edius will take native EX1 files and Vegas won’t. Go figure.

Since I’m not in PAL land, I admit to some ignorance. Nevertheless, as I recall, PAL DV interlacing is upper field first. Vegas defaults to lower field first for DV, so, something to check for. If you get the field order inverted, interlaced artifacts will be pretty bad.

VirtualDub is one of the most innocuous pieces of software I’ve ever used. To blame it for your problems, is…well….funny.

you can’t create something from nothing. you can’t get higher quality when there is no more quality to be had. the only reason you might want 4:2:2 is to improve chromakey performance

that’s arguable, at best
Tmpgenc and Cinemacraft come to mind -
Both NEO HDV and NEO HD. I upgraded to NEOHD for my EX1, but was using NEO HDV successfully with the JVC.
Other users have reported the dropped frame problem to Sony, as well as myself, but, they’ve been unresponsive

I use a JVC HD110, regularly. Vegas 8b has a great deal of trouble with captured m2t files from this camera….dropped frames, T/C read errors. The only reliable solution, I have found, is to use Cineform Neo HD, ie HDLINK, to transcode the m2t files before importing into Vegas.

9 inch rails work OK for tripod mounted configurations: matte box or short lenses mounted with the LEX.
I use 18 inch rails for a full configuration of LEX, long prime lens and matte box.
