JPEG 2000

$

Hi,

Just testing Avids Jpeg 2000 codec for the first time and I get metadata back from FFMPEG like this.

 

 

Metadata:

   product_name    : Avid Media Composer 8.2.6

   company_name    : Avid Technology, Inc.

   timecode        : 03:43:19:20

Duration: 00:00:07.36, start: 0.000000, bitrate: 61549 kb/s

   Stream #0:0: Video: jpeg2000, yuv422p10le, 1920x540, SAR 1:2 DAR 16:9, 25 tbr, 25 tbn, 25 tbc

 

So this must be wrong right?

Maybe not - 10bit JPEG2K file sizes are approximately HALF of 8bit 50Mbit/XDCAM MPEG2 - which would work out logical if the material is indeed 1:2 SAR with a resolution of 1920x540. Half the info was trashed.

If the Media Composer JP2K was 1920x1080 - then I would expect files at roughly the same size, as the codec is more advanced it can logically pack 10 bits of information into files at roughly the same size as 8bit XDCAM.

But these files are 1/2 the size and Media Composer reports 10bit 1920x1080 - what's going on with JPEG 2K in MC? where are the specs?


Issues: TransferFileToAttic / DIDRMapperHelperSegmented

$

Hello

To be brief:

We have several MC, connected through InSite-ISIS with one project drive and several media drives.

A sequence got corrupted yesterday when my MC crashed while relinking some of the files in a sequence to some newly imported clips from an AAF. Now, after writing the content to a fresh new sequence, I get the following messages in the Console. 

When saving: TransferFileToAttic Exception caught during deletion of placeholder file.

When connecting a new drive, adding/removing files, et.c.: DIDRMapperHelperSegmented::ClearAllMappers: 0 Cleared: 87 Still Alive (87 is the nr when all my drives are on, it increases for every new drive.)

I have gone in the media drive and removed all of the files I could find from the imported AAF, I have removed my local folder of the project and restarted, I have tried unmounting all drives and starting on at a time. I just want to know: what more can I try before raising a support errand?

- If there was an issue with a media folder, i would re-create the database files - is there anything similar I can to to the project/attic?

- It seems the "DIDRMapper" wants to "clear all mappers" - what does this mean?

Basically, if anyone knows what these messages relate to and have ideas on things to try, I'd be grateful.

Let's Make the Next MediaMover or MDV

$

Hello Everyone,

I think native, flexible media managementis lacking in Avid. "Have you tried Media Tool?", you might ask. Here's my problem with Media Tool - it's not easy to use. For example:

1. An Assistant Editor finishes logging, then wants to transfer the project to an Editor. He'll bundle up the assets in one folder, grab the Avid project folder, and send them over to the Editor. Might be over the network (peer-to-peer) or through sneaker net.

2. An Editor finishes his project, and wants to do a backup. Same as before - he'll bundle up the assets, grab the Avid project, and store them on backup drives.

3. We produce events that require last-minute changes. Plus, there's on-location editing that requires gathering assets from multiple users. So bundling all the assets you need before traveling is critical. Hotel networks aren't built for large file transfers.

For years, the alternatives were MediaMover and MDV. MediaMover can do all the above, but MDV is the best I've ever used. It's simple, easy, and fast.

Here's the problem with MDV. (Problems, really.)

1. It's Windows only. There are ways of making it work in OS X, but you hate them all. How do I know? Because it keeps coming up.
2. It has limitations in Wine - neither bin sifting nor folder scanning works.
3. It's abandoned.

So what would it take to create a native OS X media management tool?

First, we need to know what we're working with, the data. Are there available file specs on:

1. Media Stream Managers (MSM's)
2. Projects
3. Bins
4. Metadata layout on individual MXF's

Is it just a matter of asking someone from Avid HQ? Do you know anybody?

It's clear we need something. But everyone's busy, you know... editing. Plus you're thinking, "What can I do? I'm not a programmer!" Well, I'm an anomaly. I do what you do, but I also have some development/IT chops. They just need some refreshing. And this project would be worth refreshing them.

So what do you think? Is it worth making the next MDV? Are there any others like me who would be interested in contributing? Do you have any contacts that could help point me in a direction?

Thanks!

Report analysis: Warning adware/malware can make MC crash at startup.

$

When MC crashes and you get a pop-up window to send a report to Avid, those are actually checked, and I was looking into some of those logs and one that was quite frequent was crashing because of adware/spyware.

I could see it was crashing on: "lavasofttcpservice64.dll" after doing some quick googling I found that it's a Malware/Spyware

So don't forget to keep your System Clean from bad malware, and adware, this goes for both Windows, and Mac systems.

Since I don't know who sent in those reports, I can't inform the persons who was suffering from this about it, as the data is collected anonymously, so I don't know who is affected.

That's why i'm writing a small update here.

--

Here's a fix that I found on how to repmove this specific lavasofttcpservice64.dll crash:

1. Start Command Prompt as an administrator by right-clicking it and select Run as administrator.

2. Enter this command to reset the network adapter (end with the Enter key):

netsh winsock reset

3. Restart the computer.

4. Please, delete these two files:

C:\WINDOWS\system32\LavasoftTcpService64.dll
C:\WINDOWS\SysWOW64\LavasoftTcpService.dll

 

MC8.2 - Background Transcoding fails

$
0
0

Today I experienced a severe error with background-transcoding AMA-linked XDCAM-EX formatted files. I have marked a number of AMA-linked clips and selected Transcoding into DNxHD-120 (720P50). The clips were put into the bin and initially showed off-line status. I can observe the green circle rotating (indicating that off-line seervice is running a job). After completion of the first clip, an error message pops up, saying:

File 'M:\Avid MediaFiles\_bg.1\151_0390_01.xc.......mxf' not found. If I click on the "More"button of the erro message, the message is expanded with an additioanl line, saying:

Exception: SYS_ERROR, status:2, msg:The system cannot find the mentioned file

(Remark: I have translated the German text into English).

If I look into the indicated Media Files directory, the "missing" .mxf-file is present and can be played with QuickTime player.

If I run foreground-transcoding, all is o.k.

I have then tested background-transcoding with variations of settings. As long as I select only one disk drive for video and audio, background-transcoding runs fine. As soon as I select seperate disk-drives for video and audio, the above mentioned error pops up.

The error is serious, as the error window pops up every time again and again with the same missing file indication. I have to use Windows task manager to shut down Media Composer.

Does anybody has an idea, why it fails with seperate disk drives for video and audio? With previeous versions of MC it has never failed.

Hello forum

Just wondering if anyone has done this or similar. Basically hoping to get an 'aptitude' repository installer for Ubuntu/Debian type systems. This is currently for use with Forscene Cloud systems - which run off this operating system. 

Anyone out there any ideas as we're struggling with the Red-Hat style binary installer

Thanks in advance

we need to transfer edits from Media Composer 8.2 / 8.6 to Premiere and finally After Effects CC17/14for Compositing,

Right now we export  AMA Files XAVC Mxf.

we've tested a lot with aaf files as embedded, or media files folders, or transcoded, or consolidated - every possible opportunity - without solid success.

simple sequences - without any effects showed up as missing files, cant be linked to the media, often audio clips maybe 8seconds log showed up in premiere  6seconds, rest 2sec missing from the clip,

Anyone success in transfering -simple- Avid Sequences to Premiere? Someone using programs like Automatic Duck?

I just performed an upgrade to El Capitan 10.11.6 and AVID will not launch.  When I did the OS upgrade I unistalled MC 8.6.4 and reistalled it, I even deactivated and activated the software and it still will not launch.

I find Avid Studio's PIP feature dreadful when compared to Studio 15. I am used to clicking the PIP icon under video tools in Studio15 and sizing,cropping and positioning the pip square with the left mouse button held down...in Avid Studio, you have to input numerical values or pull  a slider bar..this is dreadfully tedious and un-user helpful...

Am I missing something here?  Would appreciate a point in the  right direction...

 

Thanks!!

Autosave very erratic

Has anyone else been having issues with auto save not saving? I've tryed versions 8.4 to 8.6 and the autosave feature seems very unrelaiable, But if I use 8.3.1 it seems fine (so far), saving quite often? this was happening across different Macs versions and Os versions, using isis or standalone, its a bit annoying!

 

But to be honest for cutting there really is no real reason to "keep up to date" just something that has been anoying a lot of editors here....

Color blocking / banding

I have a project with some footage that was shot 4K. 12 bit Camera. The footage was pushed through Adobe Media Creation and sent to me as DNX145 1920x1080. The shot is blocking / banding badly in my Symphony. The talent looks ok but her background is a vinette gradient (Lighting) No Bueno! Is the Color depth the problem? What is the correct workflow? 

 


Avid Crashes in 50P Projects

I have found that Media Composer Crashes with AMA Linked Media in a 50p Project.

I've had to create several XAVC QFHD 3840 x 2160 Class 300 OP-1a files recently and I check them in Avid for Proper Audio Allocations, Audio Waveforms and just general problems.

After AMA Linking them if I load a clip in the Source Window and then Delete the Master Clip it doesn't clear the Source Timeline and Avid Crashes a few seconds later.

It also crashes even if I haven't loaded any of the AMA Linked Clips in the Source Window and I try to exit Media Composer.

Thanks

Relinking RED R3D files via AMA not working

$

Trying to relink RED files via AMA and nothing will relink.  

Files were brought into MC via AMA and transcoded to DNX36.
Sequence bin and backup RED media provide to me.  Although the files are the same, the original clips may have come from another drive.  Not sure if that matters, but I did a test on the RED files that I got and that stuff relinks correctly.  Hmmm.
Decomposed the sequence and/or showed reference clips using MC  5.0.3.4 (latest release).
Got a Summary Report from MC and found the RED reels necessary for relinking.
Loaded RED reels via AMA.  RED clips online and visible in source monitor.
Tried relinking sequence, reference clips, decomposed clips, etc. and it don't work.
Tried moving everything into one bin and forcing relink.  Didn't work.
Tried every combination of relinking dialog and it don't work.
Checked and unchecked Source Files choice (yes, I now know it shouldn't be used).

Probably something obvious, but obviously I don't know what it is.  Help!

Saving Site Settings MC 8.?.? (Mac) Bug? Feature?

$
0
0

I always thought that any logged-in Mac user (Admin or Standard) could modify the Site Settings and they'd be saved and updated when saving, leaving the project or quitting. I now find that only an editor logged in as a Mac Administrator can do this (checking with MC 8.6.1). An editor logged in as a standard user can (apparently) change Site Settings but they will not be saved. I checked this on two systems today.

I then went back to an old v7 installation and found that a standard user can change and have the Site Settings saved for future new users and projects. This is what I'd expect. When did this change? When the Site Settings were moved out of the old Special menu? This seemingly minor change has a big impact at my university where we all have standard log-ins and have to beg the IT department to make any other changes.

Can someone from Avid please comment? Thanks.

Export mxf op1a 50i from a 25 p project

Hello everyone,

I'm finishing a documentary in a 25 p project (avid 8).

I need an mxf op1a 50 i.

I changed the project settings to 50i before exporting but when i open the file with vlc the inspector says 25p.

I think it's only a playback frame rate am I right?

 

Thanks a lot

Best Avid 8.6.5.44425 configuration for my machine

$

Hi all,

I'm hoping to get Avid 8.6.5 running smoothly on a Late 2013 Mac Pro (specs will be listed below). Avid has always been sluggish on this Mac and I'm hoping to get some system setup advice on how to get it running smooth. Currently the late 2013 8gb 21" iMacs outperform the Mac Pro. 

Mac Pro (Late 2013)
Processor 2.7GHz 12-Core Intel Xeon E5
Memory 32 GB 1866 MHz DDR3 ECC
Startup Disk Macintosh SSD
Graphics AMD FirePro D700 6144 MB 
OS X El Capitan 10.11.4

The main use will be cutting/transcoding using a 5K ISIS with the majority of the files being DNxHD 36. I've just uninstalled Avid MC and reinstalling 8.6.5.44425

Thanks!
