news report for web

[egproductions]

I am too strapped for time to test it out myself but if I am shooting a news report that will only be shown online, what frame rate should I be using. Is there a point of shooting 60i if in essence its going to be converted to 30P on a computer screen? I am shooting with the Canon XL2. Another thing to consider is that I will be doing bluescreening. Will one frame rate outperform the other for keying?

I'd say that 30p or 24p would be preferable to any interlaced mode, as the interlaced field artifacts are often noticeable on computer screens, even for objects moving rather slowly.

As a note, 24 fps 'compresses' data, relative to 30 fps, by about 16% just by the lower frame rate alone...

I understand the benifit of specific frame rates for web compression. Its actually debatable what is prefferable on bandwith alone since you aren't going to be taking 24P to 12P but taking 30P or 60I to 15P is actually acceptable in a lot fo instances.

My question was more about the retaining the feel of a 60i news report. 24P is out of the question for this reason. I am thinking that logicially if I record 60I i'm just going to need ot deinteralce on export so that I don't get interalce lines/artifacts as you have mentioned. In doing so I don't see any benefit of recording 60i since recording 30P is going to better quality str8 out of the camera as compared to a 60i --->30P conversion. Is this accurate? Will the 60i end up looking the same as the 30P? if it does look the same, is there any benefit of recroding 60i for chroma keying?

Just thought people might be interested in seeing the final product. I ended up shooting 30P at 1/60th shutter. I captured DV and exported a 4:4:4: to do my keying in AE. Exported a 4:4:4 out of AE and edited using a DV proxy back in premiere. After Editing, I imported the DV project into an uncompressed project and put the 4:4:4 files online. After this I exported a 4:4:4 clip of the finished video and brought it into an uncompressed 480x270 timline. Resized the video and applied some sharpening before I did a 400Kbps FLV export out of adobe media encoder at the same resolution.

I have just started looking at Primiere, since I have the Production Bundle. When you say you exported the XL2 (presuming SD), how did you make sure that it was 4:4:4, presumably upresed from the DV, what were your export settings?

Also, when you did your keying, what did you do to get the 'clean' edges. The Talent seems to have fairly clean hair, just by the style they have. And did you have a 'official' green or blue painted screen?

Just as a observation on the delivery, the Talent seemed a slight bit sluggish in their delivery, sort of would occasionally hesitate, at point that seemed awkward, rather than part of a 'real' newscast.

To get an uncompressed export of DV footage just lay your footage in the timeline and export ---->movie. Instead of microsoft DV avi choose microsoft avi. under compressor scroll down to the bottom and choose none. If you did a garbage matte in make sure that you choose millions of colors+ so that your alpha layer is maintained.

I know some of the talent wasn't great. The cast and crew were assembled in 2 days so casting was out of the question. Considering that I think we lucked out for the most part.

For keying I used bluescreen roll paper and the linear key in AE. Here are some tips for getting a good key (although a key from DV footage is almost never good enough for me):

light your background evenly and use zebra stripes to check eveness. when you up your exposure all the zebra stripes should appear at once.

set the bluescreen to around 75IRE

watch out for reflections or reflective surfaces

shoot HD or sideways if possible and dowrez to get extra chroma resolution

Turn sharpness completly off in the camera and add sharpness at the end of your project
