Video Stuff For Eric

Re: Video Stuff For Eric

Hi guys,

enjoyed reading these posts. I'm sticking to mpeg1 for CDs in a major way. I have cut a few clips at odd sizes. 400x300 using the MS mpeg4 v1,2,3, etc. My question is: Is there an advantage to staying with the mpeg1 compliant 352x240? ...particularly if I don't go full screen?

Any thoughts on a less than full screen (but larger than 352x240...) display for mpeg1?

Procoder sounds great. Canopus makes great stuff.

Is it not possible to 'dumb' down a MPEG2 system stream to a bitrate that can fit within the confines of a 2x CD-ROM? Doesn't need to be full D1, or at 48k, but something a bit better than 352 x 240 MPEG1?

It's the law of diminishing returns. Sure, you can move that data rate down to MPEG-1 like size, but you won't be happy with the results. The two formats are intended for two different purposes. MPEG-1 is built for multimedia, AMS style projects. MPEG-2 is built for broadcast/DVD applications. Save the space on your CD-ROM, save the headaches, and stay with MPEG-1 until MPEG-4 is really ready for prime time.

Lately I've had the pleasure of working with 24P...and, I tell ya, almost indistinguishable from film. Granted, it's still cost prohibative vs. film, Bandwidth / pipeline limitations, but real time viewing, not to mention the time saved in post...it's scary. Although I'm a purist, and love the 35 mm warmth.....HD is here to stay.

Here in Chicago, the wave is huge..many places here are revamping or already are doing HD work, so I can only imagine whats going on out on the coast.

For some reason, IM not seeing my last post from last nite....

HD = High Definition. 16:9 aspect ratio stuff with tons of data rate - Panasonic DVCPRO HD is 100 Mb/sec. Sony HD is more. It's currently the highest quality you can achieve in video acquisition. When you transfer from film, this is where you want to go. Production in HD means more expensive cameras, more expensive post-production gear, more expensive tape, more expensive everything. VERY few of my productions currently warrant such expense.

One thing that was shot in HD - Star Wars Episode II - yep, shot on video, not film. It's cheaper than shooting on film, but post-production is more expensive, since it means updating everything from studio VTRs to the waveform and vectorscopes. It requires an entire facility overhaul. Many thousands of dollars.

Speaking of sloping foreheads, here I am! Just a note on FLix, works great but file sizes get funky. Definitely a very solid product though...
