avi saving: video mode

[Jenya]

When you're making a clip and saving it as an AVI from virtual dub, what video mode should you save it as? Fast recompress, or other?

[Autraya]

yes

Use direct stream copy when you are filtering/changing the audio and not playing with the video at all. Because direct stream copy skips the decode then re-encode process you will not loose any video quality in the output file.


Use fast recompress when you are changing the video's codec but are not applying any filters to the video stream. Because fast recompress skips the filter engine the re-encode process will be a little faster. To be honest though, on modern machines you are unlikely to notice any difference.


Use full processing when you are applying filters to the video stream. This is the option you will probably use the most often.

You only want to apply full processing mode if you're using V-dubs internal filters itself (which most people prefer to do in AVIsynth anyway) because full processing converts the colorspace to RGB automatically, unless there's a V-dub filter you really want to use, stay with fast recompress. It shunts your footage directly into conversion without changing anything.

full processing converts the colorspace to RGB

Good point, I'd forgotten about the mandatory conversion to RGB. When I was editing on PCs that never used to bother me as I was on Premiere 6 which forced me into RGB in the first place.
