I just finished testing out the option of using Prores ((almost ANY codec is available under the Preview Setting drop down if you choose Quicktime primarily) as my Preview and Export codec. Things went extremely well. Here are the results.
1. Custom 1920 x 1080 1 PAR 29.97 2 min. sequence chock full of animated multiscreens, color corrections, speed triggers, scaling and 2 5 sec. AE dynamic linked flying camera motion graphics pieces.
2. Previewed with MPEG I frame. Export was 7:30. Didn’t get a total for the rendering of the work area during the building phase .
3. Previewed with Prores 422. Export was 3 min. Rendering of the entire work area during the building phase was 7.5 minutes. Of course most of the stuff on the timeline didnt need rendering to play, except the AE DL clips, but I was curious to see how long it would take.I was able to catch little things like incorrect field order and other little anomalies since when blown up with the grave key the image was clean and crisp.
I would guess the results might be the same if Cineform was chosen instead of Prores.
