Multiple home video clips... One giant AVI->MPEG encode or break it up?

[binister]

I have about 50 hours of VHS footage that I have captured. I have created a ton of AviSynth scripts to clip each captured "tape" into its individual "clips." For example, Tape 1 may have 4 avs scripts each segmenting the tape into individual clips.

My intention was to then use another AviSynth script to compile those clip scripts in a "DVD" script. For example, "Christmas DVD" script would contain all the Christmas clips.

This apparently causes issues with Cedocida/AviSynth/CCE (all MPEG encoders I have tried crash for some reason on the second pass) so I am resorting to plan 2.

My question however is would there be any quality difference between (2 pass VBR)...

1. encoding each individual "clip" script into its own MPEG2 file and then compiling the DVD from the individual MPEGs in my authoring tool

vs

2. dubbing the "DVD" scripts (collection of clip scripts) in VDub to another AVI file and then encoding that gigantic file to MPEG2.

I would assume the first method would be better because you would avoid interframe "noise" during the clip changes. But I am not familiar enough with the intricacies of MPEG encoders to know if it would really make any difference. Thanks!

Whenever you are working with video, you want to convert as few times as possible. Each covnersion will reduce the quality, and since your source is VHS, it is already quite low.

The only thing to watch is the authoring tool. Many tools by default will try to re-encode all of the input files. If you already have dvd compliant mpeg2 files, then this is unnecessary.
