    There are definitely benefits to entropy codecs like RedCode/JP2K. As Brian notes, DCT can create ugly macro block artifacts when pushed too far.

    Like most engineering choices, there is going to...

    Back in the good old/bad old days with 16GB CF cards on the RedOne, doc/nature/adventure projects had similar issues. The good news is that like old CF, the CFast2 cards are very small so you can...

    Bringing up such issues to help the RedTeam make optimum choices is one of the best aspects of this forum.

    Best advice I have for the short term is to make at least one copy for safety, then do a...

    Was not aware of the Panchro Macro 65mm. I like the idea that in addition to macro work it might be a nice portrait lens with that "Cooke look". I could easily see using one on the A camera for...

    So far it appears that the Komodo is what we hoped. RED IQ in a tiny, well priced body with global shutter. The major caveat IMO is frame rate limitations. I could see a scenario where you would own...

    Good points. Perhaps after the interminable wait for the 7,1 MacPro I've become pessimistic about Apple's timelines. I'd also note that even after the new AS Macs supplant the Intel based rigs they...

    I'd use those little T7 Samsung SSD drives and/or a RAID for media. I/O >1GB/s for reading DCT R3Ds in real time. (actual data rates still in dev, 800MB/s...

    Appears to be one of the better bang for the buck offerings from Apple in some time.

    I suspect the issue people are seeing is all about the sharpening - or lack of - in the mix. It's been an issue back to the R1 days. SOP for camera makers is to "sweeten" the image via processing...

    As much as I love the VV geometry, I have to agree that as a practical matter - S35 is the sweet spot for many motion projects.

    What's perhaps even more spicy, is the plethora of formats one can...

    Worth noting that the stampede to FF from S35 may be motivated by multiple factors.

    1) Selling new lenses
    2) You can always put a FF lens on a S35 sensor, but a S35 lens won't cover a FF (or VV)...

    My note was based on recording times to 1TB media per Phil's posts. Even if the chunkiest footy is "only" 600MB/s, it's still more than the T3/T5 SSDs can handle. Under 800MB/s will be OK on most 4/5...

    One issue that RedUsers will need to look at is sustained read speeds when working with files in the 500-900MB/s range. With the current DSMC2 "speed limit" of 300MB/s you don't need bomber storage...
