Re: [Avid-L2] AVCHD workflow for final SD DVCAM master

Thank you Bouke!

I'm always trying to teach assistants the difference between resolution and compression. Avid certainly doesn't help.

I feel better now.

Re: [Avid-L2] OT: Both Safari and Firefox have stopped playing YouTube audio

I have a similar problem with YouTube sometimes... esp on 10.6.8 and Safari 5.1.7. Firefox is going kinda crazy with updates these days. On 10.6.8, Google's Chrome browser seems to work pretty reliably with YouTube.

Don't know if that'll solve your problem. But Chrome's not so bad anyway...

[Avid-L2] Re: what are yall using to archive

 

They showed this last January, and again at NAB. But they had no shipping date or info. It's a stack of BluRays in the cartridge. Sony rates BluRay discs as 50 year archive.

Re: [Avid-L2] Re: AVCHD workflow for final SD DVCAM master

 

First a bit of a rant, can we ALL (that means Avid) stop mixing Compression
with Resolution?
(not typical for this thread, but had to vent something)

for you, DNxHD 36 is full res at HIGH compression. It sucks for delivery, no
matter the downconvert.
It will introduce a lot of compression artefacts.
Now, since you're from the PAL side of the world, you could downconvert and
work in DV.
That will even be smaller, and way better quality, and will make a fine
DVcam master
BUT, internet delivery is nowadays HD. 720x576 (and deinterlaced) will NOT
be top quality for the net.
Even YouTube is doing 1080 nowadays.

so, listen to everyone here, buy some drivespace, transcode to DNxHD 120 and
work with that.
Any half decent transcoder you have laying around will do the transfer.
Let your machine rip 24/7 and be done with it.

[Avid-L2] OT: Both Safari and Firefox have stopped playing YouTube audio

 

Hi,

This problem has suddenly appeared on my 2008 vintage iMac, running 10.6.8, Safari 5.1.7, Firefox 15.0.1. Video seems to play fine, but there is no audio playback at all. System audio itself seems fine. System sounds and iTunes have no problem, and I can stream Netflix with normal sound playback. I haven't tried any other internet video, such as Vimeo, so no idea if the problem extends to that.

I've tried reinstalling Flash to no avail. Ideas?

Thank you!

Shirley

[Avid-L2] Re: AVCHD workflow for final SD DVCAM master

 

all I have is my trusty Macbook Pro 4.1,OS 10.6.8, 2.5GHz, Intel 2 core, 4 GB RAM. From what I know 6.5 won't run on that. I can deal with that, it's the codec question that puzzles me. Is DNx 36 ok if there is a down-convert to SD-PAL.

Re: [Avid-L2] AVCHD workflow for final SD DVCAM master

Also, to the poster's original question- don't down-rez before editing, imho. Work in a finishing-quality codec, like DNx or ProRes, then convert to your target format for delivery when you're done editing.

If you don't have enough storage, buy a small raid, like a g-raid mini (less than $250,) so you have enough storage room and speed to work at a 'full' resolution. This will also work for transporting between the system you're 'borrowing' for transcoding.

While your current deliverable is SD and online, your client may want something more later - and you'll have it. You generally get much nicer looking compressed video when down-converting from a higher-resolution. As a bonus, Color correction and VFX are much easier in HD.

RE: [Avid-L2] what are yall using to archive

it's online storage that grows pod by pod. always accessible even when resilvering due to a drive replacement at about 80% of bandwidth. these can be snapshoted and or rsyncd to duplicate systems. for lightning, we have facility ups so that isnt ever going to be an issue. as for power use, the system monitors access and goes into powersaving- also the drives are all 'green' low power consumption drives.

the benefit of instantly accessing data vs loading a tape and hoping it comes up ok is really big.

also i have cpus that are running after over 10yrs of service still but in the meantime i've seen data storages go from floppys go to zip and jaz to optical disc to cd to dvd to usb drives to firewire drives to bluray and dlt to all the various lto formats that come out ever year. service life of a system has to be thought of in a data storage plan.

it's the 'ol digital dilemma discussion, no one's right, we just have to keep chasing and migrating our bits and hope we dont drop any :)

Huh? 90Tb in a single backup? One backup is no backup, if lighning strikes,
you've lost everything...
Now, the DIY build i like, but i very much doubt the efficiency powerwise...
My guestimation is that it requires at least 2 Kw.
That is one year more cost on electricity than an LTO system will set you
back.
(granted, a smaller system for editing only will also use power. I'm at the
point of powering down at night / weekends)

Re: [Avid-L2] Re: AVCHD workflow for final SD DVCAM master

This is better than doing an import of AVCHD on an older system. AVCHD import was a bit flaky.

I'm going to update our Mac Avid systems to 6.5.2 over the next few
days, but I've noticed they're mostly still on Mac OSx 10.7.3 or .4

Any reason to update to 10.7.5 ? Any gain? Any reason not to?
According to the grid, 10.7.3 is still supported.
