    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    Today I made some tests with Squeeze 8.0.1.30 and Avid-DVD 6.4.4 (Build 644B02A) on a Windows 7-64bit system. The sources were two QT-Reference files from a real project (HD720P/50), created with Media Composer 6.0 on the basis of DNxHD-120 transcoded files.

    I tested two cases, one for BD and another one for DVD.

    BluRay Disk

    For Squeeze I used the predefined preset "Blu-ray_50_720p" and modified it to the following values:

    Data Rate: Target=23700 kbps, Minimum 89% (21093 kbps), Maximum 126% (29862 kbps)

    GOP Structure: I Frames 15, P Frames 3, Auto GOPS = VSCD, Closed GOPS

    Audio: Dolby AC3, Data Rate 384 kbps, Sample rate 48kHz, 2 Channel stereo

     

    For Avid-DVD

    Project setting was HQ VBR with Minimum 15.000 kbps, Target 24.000 kbps, Maximum 30.000 kbps, Audio Dolby Digital (2/0) 384 kbps.

    The files imported with a warning, that the files will not be compatible with DVD standards and need to be transcoded for DVD's.

    When I started burning a BD-Volume, Avid-DVD did not  transcode the files and finished volume creation within less than a minute.

     

    DVD Disk

    For Squeeze I used the predefined preset "DVD_Disc_Burn_ES_PAL"  and modified it to the following values:

    Data Rate: Target=6400 kbps, Minimum 63% (4032 kbps), Maximum 146% (9344 kbps)

    GOP Structure: I Frames 15, P Frames 3, Auto GOPS = None, Closed GOPS

    Field Encoding: Top Field First

    Audio: Dolby AC3, Data Rate 192 kbps, Sample rate 48kHz, 2 Channel stereo

     

    For Avid-DVD

    Project setting was HQ VBR with Minimum 4032 kbps, Target 6400 kbps, Maximum 9344 kbps, Audio Dolby Digital (2/0) 192 kbps.

    The files created by Squeeze imported into Avid-DVD without any warning regarding the need for transcoding. However, when I started burning a DVD-Volume, Avid-DVD started transcoding one of the two clips. Then it continues to bild the DVD. While transcoding needed about 2 minutes for the 6 minute clip, the remaining processing was a few seconds only.

     

    I have tested a number of different settings of Squeeze, VBR different rates, CBR 8000 kbps, Top Field First, Bottom Field First. In all cases Avid-DVD transcoded both test files. I did not find any setting +++Edit (other than that described under DVD) Edit+++ of Squeeze, which produces an output file that is not transcoded by Avid-DVD. With all these settings, Avid-DVD created a warning when importing the files (files are not compatible with BD or DVD and need to be transcoded.

    Hi Joachim

    Joachim Claus:

    BluRay Disk

    For Squeeze I used the predefined preset "Blu-ray_50_720p" and modified it to the following values:

    You didn't tell us, but by reading the parameters you modified, I assume you used the MPEG-2 "Blu-ray_50_720p" preset ?

    MPEG-2 is also the only codec which I can successfully import in pass-through in Avid DVD 6.4.4 for Blu-ray projects (using either encoders: Sorenson 8 or TmpgEnc 5)

    For BD projects, did you try with VC-1 "Blu-ray_50_720p" ? Should theoretically import in pass-through, but some of us are getting this error: MUX_SN_E_TS_UNDERFLOW_ERR

    Joachim Claus:

    For Avid-DVD

    Project setting was HQ VBR with Minimum 4032 kbps, Target 6400 kbps, Maximum 9344 kbps, Audio Dolby Digital (2/0) 192 kbps.

However, when I started burning a DVD-Volume, Avid-DVD started transcoding one of the two clips. Then it continues to bild the DVD. While transcoding needed about 2 minutes for the 6 minute clip, the remaining processing was a few seconds only.

    mmmh, strange, I can successfully import SD MPEG-2 files (encoded with TmpgEnc 5, SS8 not tested) in pass-through for DVD burning, except maybe for file sizes too close to the DVD limit (bug in 6.1.1, I did not re-test in 6.4.4)

    Joachim Claus:
    I did not find any setting of Squeeze, which produces an output file that is not transcoded by Avid-DVD.

    This comment applies to DVD projects only, right ? You said 720p files encoded for BD would import w/o transcoding.

    BenoitM:

    Yes, I have only tested MPEG 2.

    No, I did not. But I will do in a further test.

    In my case, the test files were 322 MB and 162 MB long, i.e. far away from maximum size for DVD's.

    Yes, this statement is in context with all the various other settings I tested (other than the one described under DVD heading).

    With BD, I have found a setting which did not start a transcode inside Avid-DVD, at least not for all imported files. In a large "real" project, 4 out of 17 files were transcoded by Avid-DVD.

    For those files which were tarnscoded in the "real" BD-project, I compared the Sorenson input files and the transcoded files from Avid-DVD with "Medioa-Info". Both, the input files from Sorensen and the transcoded files from Avid-DVD have identical parameters, apart from some very minor differences in the bitrates.

    I tested with VC1 files created by Squeeze 8 and imported into Avid-DVD. They were not transcoded, however, I got the error you mentionned.

    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    Been out for a while boys, as I´m not always convinced that the latest is the greatest the BD workflows refered to is a VC1 encoded file out of Squeeze 7 using standard VC1 BD profile and BD edited in Avid Dvd 6.1.1 , works great .

    This is a workflow that I know works, I don´t often change my workflows when it comes to Dvd and Bd creations.

    Will do a fullscale test using the new versions when I get some time, reports from this forum seems to show that I have done a wise decision not letting my customers do the beta testing for me, something seems to be broke with the SS8 VC1 - Avid Dvd 6,4,4 workflow regarding BD authoring.

    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    Here is the scoop: here, importing SS8 encoded VC-1 gives the same error when importing in Avid DVD 6.1

    So at this point, it may as well be a SS8 bug....

    Well..having been tortured by this for several months, and now reading through all these posts and realising that its not just me, and seeing no clear conclusion to the problem...Angry  

    I think I'll try Grass Vallley, or Vegas, or Final cut

    Hallo Tomas,

    can you send me the detailed settings of VC1 from your Squeeze 7 version. I will try to map this to Squeeze 8 and see whether it works.

    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    Hello 

    Great thread - lot of work being put into trying things - but ....

    Now that we are half way through  2013 do we have any definitive Sorenson settings to allow a Sorenson encoded Mpeg2 file not to be transcoded in Avid DVD when using it to create anSD DVD

    I find that encoding an HD QT Ref file in Avid DVD into an SD DVD to be somewhat jerky and am trying to find a way to first encode it as a Program Stream DVD Mpeg file in Sorneson and use this file  to create the DVD in Avid DVD with no further re-encoding.

    Thanks

    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    There is a solution to this...

    After much time spent on trying just about everything, the following worked. I've done this many, many times over the last couple of days with footage that initially failed and it has not failed me yet.

    What I did was to take 1080i footage (HD), exported it as QTREF, imported into Squeeze (8.5) to generate 576p (SD) m2v/AC3 files which I then imported into Avid DVD by Sonic and DVDit Pro HD 6.4 (both work). I'm generating a SD/PAL DVD (should work just fine with NTSC) from a 1080i HD source.

    This is what I did:

    1. In Squeeze, select the 'Blu-ray_50_720p' preset. You should be able to select any Blu-ray preset. Open it up to see the settings. Where it says 'Format Constraints', pull the box down and select 'Blu-ray Disk (SD)'. You'll see the parameters change. Now, just change the parameters that you need e.g. NTSC/PAL, 16x9 etc.

    2. I use a 'Deinterlace' filter in Squeeze. In the 'Deinterlace' box, set it to 'Adaptive Blend'. You can leave the remaining options as they are ('Blend Threshold = 33'). For me, this stopped a kind of wave effect (not sure how else to describe it) when there was motion.

    The resulting file should pass through Avid DVD and DVDit Pro HD 6.4 without transcoding.

    I've been testing by burning a DVR-RW and playing it on an old DVD player. Everything plays fine. No amount of fiddling with settings (and I did many, many tests) - if you don't start with a Blu-ray preset - is going to work. You may get lucky and it works every now and again but once you make changes to the footage, it will stop working.

    I thought the quality was very good from Squeeze. Once you've got a preset working the way you like, just copy it and rename it. Do some tests and let me know if it works for you.

    Regards

    Mohammed

    Re: Are you having trouble with AvidDVD re-encoding DVD compliant MPG2 files?

    I've been using DVD Architect Pro 6-(came with Vegas Pro) it encodes mpeg 2 or VC-1, accepts a QT reference from Avid. The thing with Avid DVD is that little has been done with it in the last 4 years, HD menus are far from crisp, and pass-thru IS VERY problematic, what passes thru one day gets transcoded another day.

    Yeah! just in case theres still someone with this issue:

    I did exactly as mohammed described above, but I had to set Squeeze to 1-Pass VBR. Then I could import all clips in AvidDVD without transcoding again...(at least untill now :-)
