Hello:

Experiencing interlacing issue in 1080i > m2v for DVD.

When Avid transcodes ATSC HD Standard, Upper Field Footage to Standard DV (Avid 1:1, MXF 25, etc.) does the field order stay Upper?

Thank you for your time.

Along the same line -

1. Is it safe to say:

- an AVID 1080i/59.95 project exports  HDV Mpeg Transport & Program streams with UPPER FIELD FIRST order?

- a 1080i/59.95 project will also export out a QT REF with an UPPER FIELD FIRST order

- any After Effects comps built with interlaced footage from an AVID 1080i project should be rendered with UPPER FIELD FIRST order & imported into MC with UPPER FIELD FIRST

Thank you for your time.

 ...Your difficulties maybe stemming from your Export Settings Dialogue Box. Do not use the Quicktime Reference DV Codec setting in your Export # 1 Settings list. Rather, use the Quicktime Reference setting only. When you go from an HD source down to SD, the QT DV Codec Reference will reprocess the source material as if it was from a DV SD resoultion source, which it is not. It will assume your source is lower field first, which it is not, thus creating the anomaly you are seeing. I have included a setting example of an export dialogue box out of MC for an SD DVD Onestep process, but it is the same box as if you are going out to Sorensen Squeeze or Avid DVD. See below.....

You are correct. HD is alway upper field first.

Thank you for your helpful response -

Just to recap & clarify - When moving 1080i footage down the chain to SD DVD M2v -- you are telling me NOT to use the QT REF export in BOTH SD and 1080i projects because it is a DV codec that reprocesses footage to lower FF (It assumes all footage is DV SD)

Some old posts (from '05, '06) mention a way to Force field dominance in QT REF. Is this still possible with MC v2.8. I can no longer link to the urls in those posts.

 .....No, you accomplish the same result by setting your QT Reference setting in your export dialogue box setting # 1 to use Regular QT Reference, and MC will default to using the Upper Field First.

Bear with me - I'm exporting on my Avid so I can't get into look at the settings:

"setting your QT Reference setting in your export dialogue box setting # 1"

Is this the Regular Export dialogue box or the "Send to" export dialogue box?

If regular Export dialogue-  "#1" means the the tab you designate the file type, correct?

Thank you.

Yes - I see you mean in the "Send To" export dialog.

I am still wondering:

When Avid transcodes ATSC HD Standard, Upper Field Footage to Standard DV (Avid 1:1, MXF 25, etc.) does the field order stay Upper? or is that an idiotic question because all DV is Lower FF?

 ....Actually, the best way to explain this is to say that it translates it to the lower field first (B field), which is standard for all NTSC 720 x 480, 486, or 704 x 480 work.
