SD sequence with HD
Editing in SD with HDV video is not normally an issue – just resize as needed.
What if I have an SD sequence, and an HDV sequence, and I want to combine these for SD output (mp4)?
1. If I take the HD sequence nested and add to the sd sequence, the image quality is degraded (titles and video aliased)
2. I can copy and paste the content of the HD sequence onto the SD sequence and re-scale everything and it is ok except for HD titles which do not scale down – need to duplicate HD titles at SD settings (not a big deal)
3. Exporting various intermediate formats from the HD sequence and importing that file to the SD sequence gives acceptable results, but not super great. In Windows by the way so SD AVI or HD MP4 seem to be the choices for intermediate codecs.
I’m thinking option 2 will be best – most time consuming but you get what you pay for.
Any other suggestions?
Thanks

Hi Mike,
Not sure where you are going with the final footage, but instead of making a DV timeline, make a square pixels one. Desktop 854×480 or 640×480 depending on ratio.
You should find that your HD nested sequence no longer shows aliasing which I believe is caused by mixing different PAR sequences.

good suggestion
Along the same topic, if I export directly from an HD timeline to a non-hd format (say mp4 720×480) – any video or graphics that both a scale and a crop effect do not export correctly – things are misaligned. This is probably the same reason.
Thanks

actually, if i put the nested HD sequence on the 854×480 square pixel sequence, the scale/crop effects that were correct in HD are out of alignment. Seems the best answer there is to export to an HD native less compressed file, then pull that onto the 854 timeline.
