image blur
working on some footage using beta sp going into a kona lhe with dvcpro50. in the footage there are people walking by the screen. this was shot in a studio with a crew on a white bg. in after effects i did a luma key to key out the bg so i can have a lot of people walking at the sametime because in the original footage they shot it one person at a time. when they people are walking there is like a double image, kind of like a haze. i looked at the original footage and it’s the same there. can i do anything to fix this?

> when they people are walking there is like a double image, kind of like a haze< You realize how difficult this is for us to visualize? the most common cause, based on your mention of BetaSP, is that your interlacing issues need to be straightened out. It's a very complicated problem with digital video, your ingestion process and Kona settings, your timeline settings, and how you are viewing your output from the Macintosh. bogiesan

i use kona Lhe, component video as input and out put. the client lost the original footage. I remember looking at the original footage the last time we worked on this project and it was a double image there to. do you think this would be a lighting situation that causes this problem? i have a copy of the original that came from my system a few years back and the same issue as the original.

my kona timeline settings are codec dvcpro50 with component video, 29.97, lower filed. 720×480.
The out put is 720×486 betasp ntsc. it also looks like this on the computer monitor and from the beta tape direct to a broadcast monitor. what can i do? -

If it’s on the original footage, then it’s not an artifact that was introduced by you. It sounds like it’s some sort of reflection. Can you post a still from the original, not keyed footage?

Post a still of whatever you have, before it’s keyed.

There is no "lighting situation" that can produce such a thing. You're seeing interlacing issues, time remapping, echo filters, or just bad video. Chances are it was deliberate. You test it on your end by looking at a still image. Only you can determine if these artifacts are burned into your pixels. bogiesan

this is like a ghost image, i brought a still into photoshop and did a de-interlace and it looks the same. there are no effects on the image, i had the beta sp straight from the shoot and it was the same as now. how can i fix this? is this something that can happen wrong on the shoot. i never had this issue on my end before.

Can you please post a still and/or a short video clip of the problematic footage?

Buddy, you’re just not getting it from our point of view. Your descriptions don’t help.
