Several Errors prevented job

[pgrondin]

Following up on your post:

I set FFV1 to interlaced BFF, and left the setting of "Override input scan type" to it's Progressive default, and Auto deinterlace handling to QTGMC.

I ran three jobs:
1 A short AVI file, uncompressed YUV 422 interlaced. It ran with the desired FFV1 interlaced output.
2 The original RGB uncompressed file. It also produced the desired output, so the colour space change was not a problem.
3 With auto deinterlace set to NONE.  I got both errors. Guess I broke Hybrid.

2. Hybrid will not deinterlace if:
a. the source is progressive
b. the output is interlaced

Thank you for the clarification. I had not understood that the FFV1 output setting of Interlaced BFF would override the de-interlace setting. 
For me, at least, it was ambiguous since the settings appear to be contradictory. If I set "auto deinterlace handling" to QTGMC, and "overwrite" to BFF, the Interlace button on the De-interlace/Telecine tab is greyed out, implying that the output will not be interlaced even though I have set FFV1 to interlaced on the encoder tab. 

I now understand the priority. Thanks.

PS: the RGB uncompresssed was an unchanged default from virtualdub2 when I was creating a test file..
I am planning on using Resolve for my editing, and it will not accept AVI files from virtualdub2, so I was trying to re-wrap.
FFV1 appears to be my codec of choice, as both Hybrid, and Resolve will both read and write the format, so I can exchange files without damage.

We can call this one "Solved"
Thanks again.
