DV AVI versus Microsoft AVI

[dynamique]

Hi!
I am exporting a clip from Premiere 1.5 to later import into Adobe Encore 2.0 (authoring program) and transcode it there.
I can choose to export it either as "dv avi" (compressor says dv) or "microsoft avi", where I can choose compressor (Cinepak etc).
To use "dv avi" goes much faster, but do I loose any quality compared to "microsoft avi" encoded with another compressor? Which compressor is better?
I also wonder what it means with "compressor: none". Isn't dv always compressed?
Thanks, someday I will be an expert

DV-avi uses an avi container and the Dv codec. It is exactly the same as choosing Microsoft avi and then choosing DV as the codec. because DV is pretty fixed in it's configuration, there is no need to offer you a settings page. It is faster to write to because premiere doesn't re-render the parts that have not been changed (think Direct Stream Copy mode in virtualdub). If you choose Microsoft AVI and any other codec then the entire video is re-encoded, which takes longer and holds a greater risk of quality reduction.

I'll stick to the dv codec then.
Thanks

Compressor "none" means uncompressed. While uncompressed can be used in Premiere as your project format or export format, there is no need or particular advantage to decompress for DV source files. Premiere is designed to maintain DV encoded frames entact through to Encore if you desire. Both Premiere and Encore contain an MPeg2 encoder for DVD.

Normal project flow for DV source video (e.g. DV camcorder or Canopus type analog to DV converters) would use DV as "project format" and export in DVD MPeg2 to Encore or other DVD authoring program.

Uncompressed REC-601 YCbCr project formats are used for uncompressed sources typically found in broadcast level facilities. Project flow would normally import uncompressed SMPTE-259M format source over a hardware serial digital interface (SDI). In that type of workstation, DV video source via IEEE-1394 would be decompressed at the edit timeline. Export could be MPeg2 for DVD, uncompressed for say Digital Betacam or back to DV format.

Uncompressed RGB project formats can be used as well for typical "multimedia" type project flows.

Can you then answer my question at https://forum.videohelp.com/viewtopic.php?t=328718 ?

I said above that MPeg2 encoding is normally done in Premiere. It is also possible to pass DV or uncompressed formats to Encore for encoding but that is done less often. Export from Premiere in DVD MPeg2 format uses far less disk space.

Think through your project flow and do what makes sense.

Unfortunately I'm using a tryout version of Premiere right now, so I can't export as mpeg2 this time, I have to do the conversion elsewhere.
