What is the best way to accomplish this task so that it will yield the most accurate/uncompressed format? I'm trying get a poster printed for a buddy of mine. So far I have thought about using rasterbator @ 1mm x 10 glossy laminated A4 pages. The bmp is 2.5MB, but I'm not sure if I can do better. That was capped from GOMPlayer.

hmmm.... I'm not sure the 'best' way, but I would framegrab from VLC client to .tiff or .png at worst. I'd then not screw with it and just send it to a very good printer. For photography I trust http://ezprints.com/ Have them enlarge and print on a plotter to actual photo-grade paper. The bleed from a professional printer makes 180px/inch look like 600px/inch - and the algorithms in $100,000 canon and fujitsu printers are a little better than the rasterbator.

However, if you're on a budget I'd try rasterbate then send to a local printer and tell them to bleed print and trim the edges for you - keep in mind the images won't be bled correctly if you print them on an inkjet - which means you'll need to be verrrrry tricky with scissors or a paper cutter to make it look right.

any estimated cost?

I see about 20 bucks for 11x17. I kind of hoped I could get a bit larger than that. I might try stitching this 10 page 150MB 1mm rasterized pdf together in photoshop and see if I can filter it to be passable on a plotter.

You may want to trim out the espn logos since I'm pretty sure that image is copyrighted (since it was part of the tv broadcast)

Wait, what in the hell are you trying to do?

Just enlarge the screencap to print on a poster?

If that's the case, go download a trial of Photoshop, enlarge the picture and clean it up (remove logos, manually sharpen features), then send it to any of the hundreds of online print shops that will print it for 20-30 bucks.

Alienskin Blowup plugin will do a better job than the standard Photoshop resizing

make sure you resample it to either 150 or 300dpi

Trying to start with the most untouched/raw source image was the point of the thread. anything after that isn't entirely important.

What is the source format?

The best you can do is to load the video with virtualdub, premiere, FinalCut and do a frame export.

I was thinking VirtualDub + something else yeah. It would give me better than a 2.7MB 96dpi (I think?) bitmap right?

For normal video PNG and TIFF will produce identical images.

The size will be about the same. VirtualDub et al will give you a non post-processed image. And it won't likely have any dpi settings, it will be raw 1280x720 pixels.
