Re: [Avid-L2] New title tool

What you are describing is what I have experienced and posted about in this thread.  First I've had to be in the HD project in order to promote the Titler+.  The first one works but if I then toggled to 4K to check how the title looks and then back to HD format the subsequent promotions end up with empty page.  If I then restart Avid and just stay in HD and promote all the titles first they work.  This has been with MC 2018.12.15 or similar versions so the newer versions may not act this way but it did happen to me on multiple systems both mac and PC.  My suggestion would be toggle your project to HD then quit and restart Avid then try the promotion, not sure but that's worked for me.

Hi Marianna,

there was a lot of funkiness in how it handled Japanese.

But even if that workaround works, your team needs to make
Titler+ promote UTF8 titles!

On New Blue, it turned out I hadn't installed it (why the option
was in the Effect Pallette, I don't know...) After installing, it
should up as an option in the promote menu, but selecting it does
nothing, and using it to create a new title doesn't work either

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

Ah, that's a listing from Internet Archive. Your problem isn't really about codecs. Internet Archive does not create files. It's an accumulator. Any given listing may have multiple options and codec is not the primary attribute. It's simply what uploaders have uploaded. Some of these files may be standard definition, and some HD, and who knows what else. The codec does not define the quality. 

But you can infer. h.264 files are likely to be newer and more "standard" than other files. Some formats are obviously not video (ABBYY, PDF, SUBRIP). Looking at that listing, I'd download the h.264 files and the MPEG4 files which may or may not be h.264. My guess is the h.264 files will be newer and possibley better, but not necessarily. The "MPEG4" files are large enough that they may be higher quality even if they are older. You might also want to check the various text files because they may contain useful information about the video, such as transcripts, captions, provenance, etc...

And another consideration. If the original source is standard definition interlaced, the MPEG4 files have probably been deinterlaced, and probably badly. The MPEG2 is the only one of these formats likely to retain interlacing, which you may want in order to do your own deinterlacing. I always want to do my own deinterlacing. And if it's a film source that once had 3/2 pulldown and has now been deinterlaced, it's totally f-ed. 

The JP2 files are a shot in the dark. Could be anything. The biggest frustration with Internet archive is they they don't describe the download options in any detail. You simply have to grab them and see.

And by the way, most materials from Internet Archive are not high quality. It's gathered from the four corners of the Internet and it's mostly heavily compressed. It's best used as a research tool and last resort, not a primary source.

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

My bad, I've overlooked you forcing audio to PCM.

But, the profile tells FFmpeg if you want proxy, lt, standard or HQ.

(And it's just adding -profile:v 3 if you want HQ)

I run dozens of variations of FFmpeg, most of the time I use a pre-compiled one from the net, since my software auto downloads that saving my customers to compile themselves.

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

Resolve will play almost anything.  The only major exception is that on a PC it can't write ProRes files (it can on Mac and on UNIX with the big panel).

Here's a current list.  Even if you buy the studio version just to transcode files, it's a good deal.  Plus it's pretty good at grading…  and lots of new restoration stuff hidden under Fusion Effects on the Color page.  Free upgrades, often, always getting better.  I use it all the time.

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

Mr. Dave,
Thanks for all the great suggestions.  They are jpeg 2000 files but they seem to be scans of pages of the films contract or some such legalese.  Just a few pages scanned at 5100 × 6601 pixels.  Seems like overkill for document scans but perhaps back in the day that was the norm.  Or it's just the usual government efficiency I expect.  ;-)

Why not just open the file in Resolve (the free version will probably do all you need) and output whatever format you need?  No command lines, lots of control if you need it.

Hello John,

In your list of possible files I saw "SINGLE PAGE PROCESSED JP2 ZIP" as one of the choices…

If JP2 is actually Jpeg 2000, and it is a sizable file…AVID actually reads Jpeg 2000 natively.

You might try downloading that, ama linking, then consolidate.

Lots of if's I know.

Mp4 is indeed a container, so the video codec 'could' be H264, but it does not have to be.

Then, according to specs, Mp4 cannot hold uncompressed audio. (It can, just not by specs, hence FFmpeg does not support that.)

But 'h264' alone does not say anything. There are quite a lot of other parameters that define quality. More data does NOT mean more quality perse.

If the encoder has more time / processing power, the quality gets better with less data.

Resolution is also (a bit) important, as is complexity of the file. Noise / grain is VERY hard to compress, so that uses lots of data.

Your huge file was 16 bits video IIRC, that makes no sense at all, but does explain why it is so huge. (It's uncompressed video.)

But since it's HD, it can't be that old…

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

Thanks for this information.  There was a myriad of choices on the site including gz, which IIRC is used for phones a while back.  Turns out the big file is really grainy.  Perhaps it relates to the time this was captured.  I'll revisit the site to see what else is there but I remember most of the files I saw were in the mB size not even a GB for a 29 minute show so that's why I gravitated to the CinePak labeled section purely by it's enormous size.

ffmpeg -i <input file> -c:v prores -c:a pcm_s24le <output file>.mov

That will do a straight transcode if ffmpeg can read it, going to ProRes 422 (ffmpeg's flavor) with PCM audio. For the <input file> above, you can drag and drop the file into Terminal and it will auto-fill the path. Do the same for <output file> and just change the extension to .mov

We choose the Cinepak section which offered a 160GB HD AVI.

Nope. Cinepak is big because it's an old codec. Archives offer it simply because they have it, made eons ago. Go back and get something better. Choosing an archival download based on file size is highly problematic. Old codecs have bigger file sizes and worse quality. Many will not be full resolution because they were made years ago. The archive offers them simply because they have them and they don't know your needs.

In most archives, h.264 is going to be the best direct download version. If they offer h.265 (or HVEC), this is at least as good, possibly better. In some cases you might see a JPEG sequence (often JPEG2000) and this may be the biggest and best source. These are usually scans rather than traditional transfers. Some will offer ProRes, though usually not for direct download because of bandwidth. 

I frequent find myself downloading multiple versions because it's impossible to know which one is best until I open it. The codec is not the only parameter that matters and archives generally don't describe the files meaningfully.

Shutter Encoder and ff-Works are both good front ends for ffMpeg. Shutter Encoder is a bit more intuitive IMHO, but ff-works appears to be more comprehensive. That's based on the fact that I found ff-Works because Shutter Encoder could not do something that I needed (at the time) and ff-Works could. Don't remember what that was though.

Both are free. Both are front ends for ffMpeg.

Handbrake is still great for ripping discs and it's a much more intuitive when it can do what you need. I often go there first because its presets are very good, and very transparent, plus it's heavily documented online. You can learn a lot, even when it can't actually do what you want. SE and ffWorks expect you to know what you need.

Cheers,
Tod

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

LOL thanks. Didn't need any of that stuff, and what I offered would work impeccably for his usage. What you say my syntax lacks is intentional, as those items are either already included or included as defaults.

And your line lacks quite some stuff about quality (-profile <int> -pix_fmt yuv422p10le, -c:a pcm_s24le etc…)

I'm sure a decent FFmpeg front end will take care of that.

Re: [Avid-L2] AVI Conversion to Avid Friendly Codec on Mac?

There are settings in the video tab of Handbrake to switch to constant quality and use the RF slider.  An RF value of 0-2 is lossless.  Huge file.  Be sure to set the frame rate to same as source, or you can get a real mess on your hands.

However, I would suggest, if you have the latest version of Resolve around, see if it will load up your source file and transcode to DNX or ProRes.
