Modify the QuickTime imports to have a reel name matching the tape. Should relink

Any reason you’re not having compressor not change the name?

Create your own destination in compressor and you can choose what to add (and what not to add!) to the compressed file.

January 20, 2011 at 2:41 pm in reply to: different formats, same film compression…please!!

I’ll chime in agreement as well:
Drives are fairly cheap – if you can avoid an online/offline workflow, do so.

Otherwise, you’ll need to image every card (better back those up.)
Then transcode everything to prores – making sure you assign reel numbers to each card
Then use the timeline to recapture everything you used in the higher codec.

Why not work with ProRes LT or ProRess 422 and avoid the hassle?

January 20, 2011 at 2:48 am in reply to: What is the best format to save files in for archive purposes?

The real issue in spanning DVDs is that the DVD may go bad. They’re limited to 4.3 or 8.6 gigs (about the same length of minutes)

I’d really suggest: a) some sort of file format that includes a set of parity files (google. .PAR) that you store with the media. This way, if a file goes bad, the PAR files could possibly rebuild the media. The other suggestion I ‘d have is to move to a blue ray disc which has much larger sizes (especially if you decide to go uncompressed.)

Sigmund, I haven’t seen this before – have you tried asking the 5DtoRGB people? (Please tell us what they said! We might need that info one day?)

Annette, I know it’s a silly question: Do you have FCP installed on the system you’re looking at? If you don’t have the proapps, the XDCAM codecs aren’t on the system.

No. No audio back from motion unless it came from a ‘send’ in fcp. 🙁

January 19, 2011 at 1:02 pm in reply to: 7d H264 footage: ProRes LT or 422 for projection?

Olin – sorry to jump in, but I love this question!

[Olin Padilla] ”
If the h.264 is already compressed to 8bit 4:2:0, than is the extra information in 422 even valid? In other words, does the ProRes 422 codec actually recover more information from the h.264 than the LT does, or is the higher bit rate just redundant data? I always assumed the latter.”

The extra information? Absolutely valid. It’s just interpolated and stored – it’s essentially a similar decode to playback in NTSC/PAL on a monitor. Does it provide extra detail? No.

Codecs have a point of diminishing return for their data rate. Throw a high enough data rate at any codec, and essentially you get uncompressed video. I’m making no mention of the possibility of decoding such, mind you.

[Olin Padilla] “If 422 is actually producing better results, then why not use HQ or 4444, and where do you draw the line?
“

Let’s say that ProRes LT produces a better picture over ProRes Proxy because while they fundamentally are the same codec (and ideal for FCP), the higher data rate handles the transcoded/interpolated information better. With each step up along Apple’s codec, you get a higher data rate, less degradation from the transcode, a large file, and a less damaged picture.

Only you can say that you feel the picture quality is ‘good enough’. For some people ProRes LT is good enough – a fair trade between file size and picture quality. Going to 4444 produces less possible degradation, but a gigantic file that stresses drives. If you can’t see the difference, does it matter? If you were truly going for the ‘best picture’ possible, why would you shoot with a h.264 based codec?

So, it’s a bit of technical and a bit of opinion – where your choice to ‘draw the line’ is where you choose to draw it.

If you search in the presets (by using the search box) you’ll see an NTSC uncompressed format. You can use this – but that won’t be the proper format for blu ray.
