If you had content that was digitized in BMD MediaExpress that looks like this:
Code:
Video
ID : 0
Format : YUV
Codec ID : v210
Codec ID/Hint : AJA Video Systems Xena
Duration : 14 s 982 ms
Bit rate : 224 Mb/s
Width : 720 pixels
Height : 486 pixels
Display aspect ratio : 3:2
Frame rate : 29.970 (30000/1001) FPS
Standard : NTSC
Color space : YUV
Chroma subsampling : 4:2:2
Bit depth : 10 bits
Compression mode : Lossless
Bits/(Pixel*Frame) : 21.333
Time code of first frame : 00:00:00:00 / 00:00:00:00
Time code source : Adobe tc_A / Adobe tc_O
Stream size : 400 MiB (98%)
Source S-VHS captures
GSpot sees this file as: OpenDML.AVI
v210
Optibase VideoPump 10-bit 4:2:2 Component Y'CbCr
Given the Avisynth Convert options:
http://avisynth.nl/index.php/Convert
What is the best and least disruptive file conversion process to Avisynth ( VirtualDub)?
FFMPEG to an RGB BGR (unsure about the bt601 handling)
I see the UT codecs and I see VirtualDub FilterMod

The first order of business is seeing if that codec can open in Avisynth. Can it?

I have seen a lot of this sort of thing when I try different formats.
Avisynth open failure
AviSource couldn't locate a decompressor for fourcc v210

Is this the exact same system where it was captured?
If not, does this system have the codecs that were used to capture?
This is the problem of using proprietary codecs for capture, or even less-favored codecs.

It is the same system. Win 10 64 I7-6700K 16GB
The Blackmagic Design directory presumably installed the drivers. The Blackmagic Intensity Pro4K is configured through an application called Blackmagic Desktop Video. The capture app is Blackmagic Media Express. And then there is the free version of Davinci 14 which is appealing for certain things.
I have been assuming that the codecs are 64bit but that may not be true.
v210 is pretty open

As I look at this again it is probably looking for QuickTime support.
But QTSource knows these:

Supported color formats: RGB24, RGB32, YUY2

QTSource requires QuickTime which is not installed. So that doesn't help much.

I wouldn't assume anything when it comes to codecs. Software doesn't always install system-wide codecs, but merely uses an internal library. For example, the VLC media player.
It's still looking to be an issue of missing codecs.
The v210 may be "open", but it doesn't mean much if it's not an accepted and popular format among users of Avisynth. And I doubt it is. We exist in the land of common lossless and uncompressed (YUY2 at that), Windows only, and usually for the specific purposes of old tapes and film. In other words, it's about the audience.
Since I've never used that codec, not sure what to tell you. Either convert to something Avisynth likes, or capture to a more accepted lossless AVI.

Thanks. That's a good thought. I am not even sure of all of the different Paths where they might be found. Windows installers can sprinkle them like fairy dust.
Where must they be for Avisynth?
In the meantime I have been using FFMPEG for trimming and prep.
