Hi,
I want to encode videos using DV to xVid. Working with DV is not an option. Don't suggest buying a large hard drive, getting a new computer or anything that suggests I should work with DV.
Would this be a good workflow? ::
1.capture DV
2. convert to intermediate codec, h.264 intraframe compression only
3. work/store h.264 data, delete DV data, finally export to xVid
would this workflow end up having roughly the same quality as DV directly to xVid?
does this intermediate codec contribute to a huge degradation in quality?
is this a reasonable, common practice way to do this?
is AVC-Intra 100 better to use?
Any and all answers welcome, just don't suggest I work with and store DV! Thank you.

I'm still trying to figure out how you are going to convert to even h264 if you are not willing to work with DV....which also happens to be your source.

I can have DV footage stored temporarily, yes. That is a necessity here, no matter what route the conversion goes.
I am aware that h.264 is more difficult, yes. Correct me here if necessary in this:
Since h.264 can use only intraframe compression, I can use this with no increased difficulty in editing. I would take the DV, use intraframe compression, and still be able to edit easily while maintaining some quality and a smaller file size.
note that I do realize that h.264 uses intra and inter frame compression, but i have heard it can use only intra frame -

No, I would re-read that other thread
h.264 can use intra frame compressoin, and it's easier to edit than long GOP h.264. But intra frame with all the options activated is still more difficult to edit than DV because it's more compressed (more compression means more CPU required to decompress when editing) . Features like CABAC and inloop deblocking for example take a heavy toll on CPU for decoding. You will not like it on a single core, even for SD footage . But if you disable all those features, it becomes almost as bad as older formats compression wise
Excellent to hear a suggestion. So is every frame a keyframe in DV50 video?
Is the codec available for download anywhere? -

Absolutely true, But it not for me
For chroma, I usually upsample it differently in other programs than an NLE or AE which use low quality point (nearest neighbor algorithm) resample, even from 4:2:2 subsampling . Also I use uncompressed for compositing. Even the smallest DCT artifacts can negatively impact your compositing
The OP's main goal was to reduce filesize for editing
