  • Can’t render effects in 480 lines, only 486???

    Posted by Cory Caplan on August 26, 2007 at 10:12 pm

    I have a sequence that’s dv50 using primarily dv25 footage. I have some dv50 in there, and some still graphics that came from a PSD which was imported into a sequence that’s 720×480 (automatic) In other words, everything about this sequence is 720×480.

    It’s a habit I’m keeping from the AVID– don’t mix 480 and 486 lined stuff. The AVID couldn’t handle it well (especially qt refs– useless)

    However, I think it’s insisting on rendering some transitions at 486 lines. I’ve got some graphics in V2 over some footage, transitions on both lines (ones a dip, the other a fade in/out) and during the rendered transition, the graphics “grow” up by a pixel at the top and down by a pixel at the bottom– what would happen if it rendered the effect in 486 lines. Is the DVCPRO50 codec 486 lines on FCP or something? Other footage with effects (magic bullet, SA color finesse*) don’t jump, they appear to render just fine in 480 lines.

    Also, I swear that on some speed ramped stuff I’m doing, it’s also rendering in 486 lines– essentially anything that uses the “motion” tab gets 486 line treatment. I’ve got a house with vinyl siding, shot straight on, and during the motion effects, the “lines” between the siding bob up and down– looks like 486 lines to me.

    6.0.1, Kona LHE 4.0 etc etc..

    Anybody experience this?

    (* BTW, I think it’s assinine that I still have to use Color Finesse as a workflow because COLOR has such a kludgy interface with studio and a complete inability to reconform. It should just be an effect in the timeline anyway, rather than a seperate editing program. Or here’s a freakin idea, how about migrating some basic color functionality into a FXPLUG type effect that works in RT???)

    Also, I forgot to mention that making the sequence 486 lines and into a prores hq timeline “fixes” this problem.. however, I prefer the DVCPRO 50 codec, as PRORES is softer & bigger based on my previous testing (loss of detail in low contrast areas is especially noticable.)
