Working with video in Pro Tools part 9

To recap, you should always try to get an embedded OMF, which will provide you with all the audio files and edit information in one large file. The only other file you will need is the video — which, in a nutshell, can be in any format you like as long as it is a QuickTime movie and preferably a DV movie. It is very helpful if this includes ‘burnt in’ time code so you have a continual visual read out of the time code on the video screen.

First, import the video, following the instructions described in Part 6. Remember that Pro Tools will always put the video file at the start of the session. Your Session will now contain a Video track and a Movie. Go to the start of the Session and view the first frame of the video. Look at the burnt-in time code and set the Session Start Time in the Session Setup window to the same time code value as the first frame. Alternatively, you can set the Session start time to a value before the video start time to leave space for line-up tones and the like. To do this, Change the Session Start time in the Session Setup window to the desired time; when you hit Enter, a dialogue box will come up. We need to make sure the video stays at the correct time code position so select Maintain Time Code and you will see that the Session now starts earlier but the video has remained at the correct time code.

We can now import the OMF into this Session to bring in all the audio that has been laid up by the video editor. To do this you must have DigiTranslator 2 installed and authorised on your machine. Select Import Session Data in the File Menu of Pro Tools and the usual navigation window will open. Select the appropriate OMF file, click on the Open button, and a variation of the normal Import Session Data window will open, showing a list of the audio tracks as they were in the video editing package. Leave all the tracks set to New Track, but before you click the OK button you need to look at some of the tick boxes and pull-down menus.

Take a look at the bottom left-hand corner. For instance, I tend to change the pull-down menu from ‘Ignore clip-based gain’ to ‘Convert clip-based gain to automation’. I also untick the ‘Pan odd tracks left/even tracks right’ box as I find these defaults are more often wrong than right, and anyway I tend to rearrange things on to different tracks very soon after importing the OMF into my Session.

Then take a look at the left-hand middle section. I prefer to set the upper pull-down menu to ‘Copy from source media’ so that Pro Tools creates new audio files in the Session’s audio files folder. This way, the Session doesn’t remain dependent on the embedded OMF file, which may get lost if the Session is moved around to different drives and/or systems later on in the work flow. On this occasion you can ignore the Video pull-down menu, as embedded video files in OMFs are not supported by Pro Tools and anyway you already have your video file on its track in the Pro Tools Session.

Finally, you can click OK. Pro Tools will start copying the audio files across and they will appear on the Edit window as each one is done.

Now you can start work. One the first things I do, is to re-organise the track allocations making new stereo tracks where appropriate. This is necessary as, like older versions of Pro Tools, neither FCP nor Avid supports stereo tracks, so the video editor will have split all stereo material across two tracks. So I move all stereo material across on to stereo tracks and re-organise the other material on to tracks that suit your way of working. Then you can start work on the material.

Wave Rider release a demo video

Vedat at Wave Rider has released an excellent video showing how to use Wave Rider.

It is a serious case of a picture paints a thousand words, it is clear and shows what the effect of adjusting each of the controls will do.

Well done Vedat.

Avid Digidesign give Mix legacy hardware a reprieve

This is what has been posted on the DUC announcements forum…

Hello, all,

Last month, I posted a note on this page stating our intention to revisit our decision to remove support for Mix-era peripherals in our next Pro Tools release. After reviewing the technical challenges and, in no small part, considering the needs of our customers, we have listened to your feedback and decided to retain support for Mix peripherals beyond the current 8.0.1 release. While I hope that this is good news for most of you, please understand that there are no guarantees as to how long we will be able to maintain support for these and other legacy hardware products. We will continue to evaluate compatibility issues like this and our commitment to you is to do our best to provide you with as much advance notice as possible when similar changes are required. Thanks again for your feedback, understanding and your continued support of the Pro Tools platform.

To see the whole thread go here on the DUC.

So it looks as though, at least for now, those using a Mix interface like an 888-24 on the legacy port of an HD interface like the 192 I/O will be able to for some time longer but it would still probably be worth looking at saving up for an alternative solution if you need that extra I/O regularly because I can’t see the reprieve lasting for ever.

More on Wave Rider on the Digidesign User Conference

There has been some interesting comments on the Wave Rider thread here on the DUC.

Stereosurfer asked…

Is Wave Rider only works on first insert slot?

This is a great tool, tons of thoughts to use this baby, like putting a de-esser in listen mode in front of WR to take out sibilance and pop in a more natural way…etc, so many possibility, but… I only have it working 2 times on Insert slot 2 or 3, and often it is not working correctly also on first insert slot, mostly the fader goes all the way to the top or the bottom, with default setting, and if I move it to another track, 100% chance a working instance of WR will go crazy after moving.I am on OS 10.6.1 and PT 8.03pr, both LE and HD, no other controller. Any idea?

Vedat (the designer of Wave Rider) replied…

Insert slot should not affect WR. But it should be put after all the other plugins to reflect the added gain.
If you’re having that full gain or full attenuation thing, just switch to Duck mode momentarily and switch back to Ride. That fixes it.
It’s a rare occurrence, we can’t pinpoint what makes it go like that. It might be related to opening or importing sessions that already have Wave Rider on them.

Is this your first try of WR, or have you installed an older version in the past? If so, please do a clean install as described in the installation document.

Cheers!

Edit: I just realized you’re on 8.03pr. Apparently there are a few glitches Digi will have to iron out on that puppy.

Badjitter also asked…

I have tested WR only limited time, but I think it works often too hard to match the levels. What I would like to see:

1. Target volume (WR has slider named output). If your audio is already making that output level, it should keep the volume slider at 0. Is it already making that?

2. Slider to adjust the behavior to louder and softer signals than target. Something like compression ratio. Often I wouldn’t want to flatten the levels, but add +3dB gain to signals that are -6dB below the target volume and add negative gain of -3dB to signals that are +6dB above the target volume. Makes sense?

Vedat replied…

Yes, WR will target whatever you set with the output slider. If it’s already that than it will keep it that way, but you’ll still see micro adjustments.

If you set your silence level high enough, you will find that low level signals aren’t boosted as much, depending on the behaviour slider. I am finishing a video hopefully this weekend to explain all this.

Kopper then mentioned Waves and their new Vocal Rider product…

“Vocal Rider is the first of Waves’ new series of mixing tools. This plug-in automatically “rides” the levels of vocal tracks. Instead of manually riding the physical mixing console fader or drawing in every level change on a DAW track, Vocal Rider does it automatically.

First, the user sets the target range of the vocal level in relation to the rest of the mix. Vocal Rider then compensates for all deviations from the target, raising or lowering the vocal volume. Unlike compression, Vocal Rider adds no additional coloring to the track.

Vocal Rider will soon be available from authorized Waves dealers and online.”

Sounds like Waves is going to take the Wave Rider approach… Another case of the “big guys” stealing a concept from the “little guy”?

To which Dmazurek replied..

Not really. The WR plug is meant to level out the audio based on internal dynamics. Sort of like a auto compressor. The Waves plug is designed to level the vocal against the rest of the mix by using the sidechain. Similar concepts but different intent and results it seems.

I saw the Waves plug at AES, and it was just dumb IMO. Just mix the song for goodness sake, why do I need a plug to do that?? Especially for $400/800 native/TDM.

Vedat added…

Well at least we know they were lurking around here too.

Maybe you could do feature requests and bug fixes for other Waves products on this thread, cause it may be the only place they are looking at these days.

Finally PhilBuckle added this strange commendation for Wave Rider..

This thing is so cool.
I’m going to have to buy it.
I therefore hold you personally responsible for increasing my credit card debt.
Damn all you coding type people with cunning business tactics!!

Well the conversations do continue and I am interested to hear about the differences between Vocal Rider and Waves Rider. I am hoping to be able to do a comparison soon, just waiting for Vocal Rider to come out. But it does look as though Wave Rider has a number of unique features, not least of which is ducking.

Working with video in Pro Tools part 8

DV Toolkit 2 is a post-production bundle for Pro Tools LE 6.1 and higher, which enables various features otherwise only available on TDM systems, so providing you with the opportunity to ‘work to picture’ using a very cost-effective LE-based system. Firstly it enables the Time Code functions, including the Time Code ruler, and so enables you to edit to picture with time code accuracy and convenience. It also includes Digitranslator 2.0, as described above, which handles the OMF, AAF or MXF exchanges. Included in the bundle are Digidesign TL Space, Digidesign X-Form and Digidesign’s DINR Audiosuite plug-ins to help with de-noising any dodgy audio that might come along your way. This is nice, though it has to be said that DINR is getting very long in the tooth these days and can’t really compete with the likes of WaveArts and Izotope RX.

Having looked at the tools available to you, in the next few episodes, let’s go through the process of getting an OMF into Pro Tools in more detail. Always remember that most problems with OMF imports stem from OMF creation problems on the video editing system. It is very important to co-ordinate in advance with the video editor to make sure they create the correct format of OMF file.

Wave Arts release plug-in updates

Waves Arts have released v5.49 of all their plug-ins. This is from their web site…

This update features official Snow Leopard support on Mac and a number of other fixes and enhancements. Please visit our Downloads page to get the update.

  • (Mac) Snow Leopard compatible (fixed graphics glitch)
  • fixed problem with TrackPlug menus sometimes not working
  • fixed TrackPlug Height knob not reverting to default value properly on certain bands
  • fixed Mac installer issue (running it the first time would result in Resource Not Found error)
  • fixed occasional graphics glitch in MultiDyanamics in which hi/lo arrows appear above frequency display
  • fixed pops in MAS versions when using pre-render mode or bouncing
  • fixed RTAS/AudioSuite window bugs (wrong offset, controls behaving strangely if RTAS/AS window open at same time)
  • fixed issue with vintage RMS compression causing constant attenuation for thresholds below -48 dB
  • added peak input/attenuation level displays in TrackPlug

I love their Restoration plug-ins. Especially for wide band noise there are usually my first port of call as I can get good results quickly.

You can download these updates from the Download page on WaveArts’ web site.

Waves announce another plug-in at AES – LoAir

Very little info on it so far…


LoAir is a sub-harmonic generating plug-in which creates LFE content or “rumble.” This tool is perfect for sound designers who want to add dramatic effect to existing audio. LoAir consists of four separate components: Mono, for creating and enhancing subharmonic frequencies on existing LFE tracks; Stereo: for generating LFE content from Stereo signals (Outputs LFE or Stereo + LFE); 5.0 to 5.1, for generating LFE content from a 5.0 signal; and 5.1 to 5.1, for increasing subharmonic frequencies on existing LFE tracks.
Sound designers and post-production mixers alike will greatly benefit from LoAir. Waves is making this tool available following many requests from users in the post-production field. The first notable sub-harmonic generator for Pro Tools, LoAir is the only one capable of processing polyphonic audio content and creating 5.1 output from 5.0 sources.

LoAir will be available soon for both Mac and PC as a TDM plug-in. Pricing has yet to be announced.

Even more free impulse responses

Following on from my posts here and here, I have just come across this link on Mac OSX Audio which lists loads of sites with free impulse responses.

Take a look….

Waves announce a vocal rider plug-in at AES

Waves have used AES to announce a vocal rider plug-in that is very similar to Wave Rider that I have covered earlier on this blog both here & here.

The Waves plug-in appears to be the same but different. Sound on Sound have a video demo and this is what they say…

SOS Mix Rescue guru Mike Senior is a fan of automation-based fader-riding, and the technique is mentioned many times. The technique involves manually drawing fader-adjustments in the DAW to balance the level of the vocal track relative to the rest of the mix. Though this method of vocal leveling can be rewarding, it is undeniably time consuming. Waves Vocal Rider is an intelligent plug-in which generates this volume automation. It compares the volume of a vocal take with that of a backing track, which is fed into a side-chain. The resulting volume adjustments are written as fader automation within a range set by the user, controlling the dynamic of the song without introducing any of the additional artifacts associated with compression.

Well two riding plug-ins in a relatively short period of time. It would be interesting to do a comparative review of them both to see how they both perform.

Waves announce new WNS noise suppressor plug-in

Sound on Sound have produced another video of Waves demoing yet another new plug-in…

Billed as “the first in a new line of dedicated Waves Post Production tools”, WNS Noise Suppressor handles real-time noise reduction across six bands. Designed for dialogue post-production, the plug-in purports to detect and remove both constant and modulating environment noise. Joining WNS in the post-production category, LoAir is intended for use in 5.1 mixing, generating and enhancing sub-sonic LFE (low frequency effect) content from an mono, stereo, 5.0 or 5.1 source This is one of the many plug-ins designed for post-production that could find a home in music production, especially in genres which demand thunderous bass content, such as hip hop. Multirack is designed as a software solution for front-of-house engineers, providing Waves processing for live mixing. The interface displays channels as effects-chains, and allows an engineer to replace racks of hardware with a laptop and an audio interface.

This is good news as Waves have dropped behind in the noise reduction stakes and this is bound to find a home in more and more audio post houses as we get asked to reduce the background noise on more and more material.
