Jerky interlaced footage on Adrenaline-not Meridien
Hi,
I was wondering if someone could explain this to me. A doc with many different sources is being prepped for finishing at our place. The project is 25p. The footage was digitized on our Adrenaline via SDI at 1:1. Most of the footage was shot progressive, but some was interlaced. To no one’s surprise, when the interlaced video was played back on the Adrenaline it was jerky. The 3prong Speedramp plug-in was applied to these shots to de-interlace them and then, upon playback they looked fine.
The footage was consolidated and sent across town to a facility that has a Meridien-based Symphony from “back in the day.” Once the footage was copied to their Symphony, the shots that had the 3prong plug-in would not play back (note: the 3prong site stated that once the effect was rendered on one machine, there was no need to have the plug-in if you move to another machine). In any event, the de-interlaced shots would not play back so the Symphony editor removed the 3prong effect from the clips. Having done this, the interlaced clips, completely uneffected, played back just fine in the timeline along with the progressive clips.
Does anybody know why this is? Does the Meridien hardware automatically de-interlace footage in a progressive project? BTW, this doc is going to a film print and does anyone know if there may be problems down the line by mixing the the progressive and interlaced footage?
TIA,
LJ -
