Hello Adobe users.
I am a professional motion graphic user, although strange I need to adress these issues.
I have made about 300 motion graphics job that run on national TV and I have delivered them always in progressive SD quicktimes.
Nobody complained about it and it seems fine on TV (no judder ect.) Propably because they import my SD uncompressed quicktimes into Avid/FCP and the system makes it interlaced.
Recently I had some editors that only wanted SD interlaced footage and they cannot seem to handle the progressive files.
No problem for me. I just render it out with Upperfields and deliver them. But I have seem some issues with jagged edges that are beyond the normal interlace/deinterlaced jagged edges.
The problem is very apparent when you have an vector file and you rasterize it (collapse transformation button *) in aftereffects.
When you render the animation with Upperfields and you review the footage interpreted as upper in aftereffects you really see very jagged edges.
When you turn of rasterize or just replace it with an PSD (of the same vector) you dont have that problem. I have tested it out many times and it seems to be a problem with the continue rasterisation proces. Is this a known bug or is there some kind of explenation?
Also, it's normal to make interlaced footage progressive because if you scale/rotate/blur an interlaced file you will get strange effects and flicker.
But if you have to add text/graphics to a real progressive file (from alexa/red or renders from a 3D package) and you render this out as interlaced footage you are basicly rendering the text/graphics out as 50 different fields (like it should be) but the progressive footage does not have those fields, you are just showing frame 1 two times both Upper/Lower, frame 2 two times ect.. ect.. So you are mixing a very fluent text/graphics animation with an progressive file that has been interlaced (without having real 50 different frames). What is the solution for this? Render it all out progressive, reimport and render out that movie in interlaced? Because making the progressive footage into interlaced, than deinterlace it in AE and render out in fields, you are decreasing the quality of the footage alot! This drives me crazy
Two quick examples. The file is a illustrator vector.
In the first example the vector is 100% size, footage rendered out in fields and reimported in AE. Screens taken from AE. The compsize is 720x576 widescreen pal. I took screenshots without even previewing it stretched out to widescreen, because it gets a lot worse even. This is a raw pixels comparison. I scaled the example up 200% so you see the difference a little bit better.
The second example shows the vector sized to 270% with continued rasterize ON. Also rendered out in fields and reimported with upper fields interpreted. Compsize is 1024x576 square pixels, so there is no added stretching of the footage involved.
