    2018.4 WAV exports and Link to WAV files problems

    Edited due my bad cut and paste...

    There have been a few threads about 2018.x and WAV file Linking problems:

    http://community.avid.com/forums/t/183802.aspx

    but I wanted to start new for this 2018.4. 2018.4 is now including iXML metadata in the WAV export. Most of my testing has been on the PC side for this so am posting here.

    1080i/59 Project

    1. 2018.4 Export (using Marks) a 24bit 48K Direct WAV from a DF timeline. Sequence Start 01:00:15;00, Mk In 01:00:19;00, Dur 10;00.

    2. 2018.4 Link to #1 selecting 29.97 DF. Master Clip shows In 01:00:14;29, Dur 10;01.

    3. 2018.4 Import #1 selecting 29.97 DF. Master Clip shows In 01:00:19;00, Dur 10;01.

    4. MC8.6.5 Link to #1 selecting 29.97 DF, Master Clip shows In 01:00:19;00, Dur 10;00.

    1080p/23 Project

    1. 2018.4 Export (using Marks) a 24bit 48K Direct WAV from a timeline. Sequence Start 01:00:15:00, Mk In 01:00:19:00, Dur 10:00.

    2. 2018.4 Link to #1 selecting 23.976. Master Clip shows In 01:00:15:00, Dur 10:00.

    3. MC8.6.5 Link to #1 selecting 23.976, Master Clip shows In 01:00:19:00, Dur 10:00.

    This is the console from 2018.4 for an 1080i/59 DF Export and then Link. It was a previous export test.

    Direct out export - audio master fader gain and effects are not applied.
    Audio Mixdown will require 8639040 bytes. AudioSamplesInSequence= 2879680, SequenceLength= 1798, DestinationBytesPerSample= 3, numOutputChannels= 1. 8436 KB needed.

    ------  AMA Link To File(s)  ------

    Note: iXML time reference and BEXT time reference do not match.
    File frame rate of 29.97 obtained from iXML applied to a start time from iXML samples since midnight
     [ Plugin Name = WaveAiff Plug-In Avid Technology, Inc. Version = 1.7.2.10091 ] processed Z:\Miscellaneous\Audio_LKFS\TheBullpen\MixdownWithMaster-0_V.wav

    Unless I'm missing something there are a couple of issues here that need to be sorted out. It is a very common workflow for us to export wav files for clients, and we always want to check our exports by Linking back in before sending them to our clients. Does anyone else use these methods?

    Re: 2018.4 WAV exports and Link to WAV files problems

    A bevy of start time and duration issues were fixed for 18.5, both import and AMA linked. You can now round trip and the re-imported media should match the exported in start time and duration. There was some refactoring that occurred for 18.4 that threw it off for a bit, but I think it is back on track now.  I think if you try this in 18.5 you will see improved consistency.

    I am a bit concerned about the obseration that BEXT and iXML disagreeing on the start time. I've reprodued that behavior 18.5 and will be looking into it. (For the record, the value in the BEXT is correct, the value in the iXML is not.)

    jlomicka,

    Thanks for your reply. I was going to jump on 2018.5 but I did not think I saw anything in the readme about Bug Fixes for this. I'll get to testing ASAP.

    I figured the BEXT and iXML disagreeing on start time was why I was getting my Sequence Start Time from iXML in the 2018.4 Link and my Mark In Time from BEXT with Legacy Import and with MC8.6.5 Link.

    Re: 2018.4 WAV exports and Link to WAV files problems

    jlomicka,

    I have done some testing 1080i/59 with 2018.5 this morning. I see some change in Linking but I am still getting the Sequence Start Time rather than the Mark In Time. I tested with my original 2018.4 WAV export and a new 2018.5 export, not seeing any difference. The console still shows the BEXT and iXML disagreeing on start time message.

    1080i/59 Project

    1. 2018.4 and .5 Export (using Marks) a 24bit 48K Direct WAV from a DF timeline. Sequence Start 01:00:15;00, Mk In 01:00:19;00, Dur 10;00.

    2. 2018.4 Link to #1 selecting 29.97 DF. Master Clip shows In 01:00:15;00, Dur 10;00. (* In and Dur changed but not correct, showing Sequence Time)

    3. 2018.4 Import #1 selecting 29.97 DF. Master Clip shows In 01:00:19;00, Dur 10;00. (* Dur changed, now correct)

    4. MC8.6.5 Link to #1 selecting 29.97 DF, Master Clip shows In 01:00:19;00, Dur 10;00. (* has been correct)

    Give it a go and report back.  I few others seeing similar things have reported good results qith 2018.5.

    Re: 2018.4 WAV exports and Link to WAV files problems

    Hi Marianna,

    Linking is not usable to us because the Timecode in the Master Clip is the Sequence Start Time (from iXML) and has nothing to do with the Timecode of the actual In Mark on the timeline for the WAV export (the BEXT in the file).

    Hope that makes sense... Don

    Re: 2018.4 WAV exports and Link to WAV files problems

    The incorrect start time problem is a serious bug, and it persists in 18.5 I've reproduced it. I haven't yet had time to look into the fix.

    There is a "toggle file" that can be used to turn of the iXML export.  If that would be helpful we can probably arrange for you to get that.  If you run with the toggle, the .wav exports will not contain the iXML start time, and the downstream import will use the BEXT start time instead.

    Re: 2018.4 WAV exports and Link to WAV files problems

    Jlomicka,

    We do not currently deliver to a client who needs the iXML start time so that would be a good work around. I can PM Marianna to see if it can be made available to us.

    Thanks, Don
