Re: [Avid-L2] AMA file Export

 

I keep careful track of my renders so they are all to the same codec, usually DNX 175X or DNX 220X and I render an upper track safe color limit and fill all filler areas with media of the same codec.  This allows a QT Ref export that I take into Adobe Media Encoder and let it do the H_264 while I continue in Avid.  This requires some careful attention to the render settings so they aren't set to same as source and it probably works for me because I'm doing the online so I don't have other hands on the sequence and project.

If you AMA export to DNX in MXF OP1a, you have the option to do a mixdown to stereo. 
Then you have a nice in-between for encoding to H264.
FFmpeg can do that for you, and add the BITC if needed (And a logo if you want), and it can start while the Avid export is still running.

Only gotcha is that FFmpeg has to be slower than your export, or it will find quit the  encode while it has catched up with Avid's export.
So a few options:
Set FFmpeg to be dog slow (That will result in gorgeous but very low bitrate files.)
Or, learn how fast your export normally is, learn how fast FFmpeg is with your recipe, and do the math on how long you have to postpone the transcode.

(AME with a watch folder is also an option…)

So, once you've set it up, it's a simple few mouse clicks export and you can walk away, or start using your avid

I'd do a video mixdown cut into seq then do a SAS export.
Still dnx36 size but I'd have a watch folder setup on a server to grab those sources and make H264 outputs off the Avid.

Have you tried the highest rated email app?
With 4.5 stars in iTunes, the Yahoo Mail app is the highest rated email app on the market. What are you waiting for? Now you can access all your inboxes (Gmail, Outlook, AOL and more) in one place. Never delete an email again with 1000GB of free cloud storage.

[Avid-L2] OT: Betamax capture

 

A friend of mine is working on a show and needs to get some archival
material off of a Betamax tape. The length of the recording in unknown
but it's 1 tape so less than 2 hours. Thoughts on a reasonably priced
service to get this into a digital format? Thanks. --J.B.

Re: [Avid-L2] AMA file Export

 

If quality is not an issue, set Media Composer to export H.264 single
pass and it will do it fairly fast. If quality is an issue, export in a
native format and compress elsewhere. --J.B.

RE: [Avid-L2] AMA file Export

 

Our experience is this is about 4 times slower than Dnx36 so H264 takes about 2 x realtime to export while DNx is about twice as fast as realtime. So on a 45 min show that's the difference between 90 mins and 22mins

Re: [Avid-L2] Avid Stabilze tracking accross transitions?

 

Hi John, my experience matches yours. I routinely use the stabilize effect amidst transitions and my workflow is to nest before stabilizing. If you want to keep your timeline clean, you can remove the nest after the stabilizer has finished its analysis.

From what I can tell, the Avid stabilizer is analyzing the video motion on a "per track" basis and not "per clip," although it operates on the duration of the clip. So if you have an effect or transition on the track, it will include that data in its analysis, which is why nesting gives you the clean stabilization.

If that cramps your style, you can also use the BCC Optical Stabilizer, which works very well and is more robust, giving options for stabilizing motion, smoothing motion, removing zooms, &c. I believe it analyzes motion "per clip." Hope that helps!

David

When I drop the stabilize effect on a shot with a transition it seems the fluid stabilizer is trying to stabilize across the transitions final multiplexed image and not just the shot I'm putting the stabilizer on but it's hard to tell if that's the case.  Auto nesting a submaster allows for a clean stabilization throughout the transition. 

This is a bit difficult to test.  Sometimes with swish pan effects it's hard to see if the stabilizer is mis-tracking but sometimes a fade to black will start to drift a bit or a dissolve as the b shot comes in.

Does anybody know exactly what the Stabilizer Effect is looking at during transition areas?

Re: [Avid-L2] AMA file Export

 

Export to file quicktime- H264 and limit data rate to 5000-8000. choose only selected tracks. 

make the dimensions smaller perhaps rather than 1920x1080

[Avid-L2] AMA file Export

 

Hi there

 

We have been doing some research to try and find the quickest and simplest ways to export from Avid for viewing – it seems by far the quickest way is an AMA export and also the least number of steps, especially with timecode burn in and effects to render.

 

Dnx is the quickest one to export by far but DNx36 is kind of too big and also only progressive and we want interlaced… - We can switch to a P project but we’d prefer to stay in an “I” project

 

Sony XAVC AMA is promising but it exports the audio tracks directly so you have to do an audio mixdown first.

 

 

So has anyone come across any other AMA plugins for export that might do this or anyone have a way to pimp the Dnx36 codec to make it something smaller – so little secret text file that changes the data rate?

 

Thanks
