  • Avid H264 Offline Codec - SD raster possible?

    Hi, After implementing JFIF 4:1s for our client - I wanted to explore what offline codecs were possible with Media Composer, and I have hit across what seems like an obvious oddity. At the very bottom end - using AMT you can produce a 0.8Mbps H264 proxy, or a 2Mbps H264 proxy. Stepping up from here, you get into JFIF 4:1s (approx 12Mbps), before then

  • Re: Adding Timecode Track to OPAtom

    Vadym, For now I have resolved this using the libmxf tools, compiling our own version of BMX that supports the required JFIF variants that we are using (e.g. 4:1s). I am doing some other work on getting the metadata updated for AMA linking, and so will publish here my final OPAtom for reference when I have completed it.

    Understood - my only interest here is MediaComposer showing the timecode. To confirm - the screenshot you provide was achieved by adding in the OPAtom directly - without adding in the associated AAF? I will repeat my tests tomorrow and confirm - providing screenshots.

    Well Media Composer critically - it shows no timecode. But then also MediaInfo, FFMPEG, FFMBC - none of these show a timecode stamp.

  • Re: Adding Timecode Track to OPAtom

    The workflow is the OPAtom media will be ingested via a referenced an AAF file - and so of course the AAF file can contain the timecode track for the OPAtom. However - we are wanting to keep this secure, and so we need to have the timecode stamped onto the file. If we look at a file export to JFIF from Avid Media Composer - we see a timecode on the

  • Re: Adding Timecode Track to OPAtom

    I have suggested this back to our client - and have received the following reply; "...This wouldn’t normally be the case with Avid media. When generating media via any solution to Avid OPatom, the TC would definitely be baked into the file. As AAF delivery across platforms is not always guaranteed and sequences can modify the metadata it

  • Re: Adding Timecode Track to OPAtom

    The issue is that when opening the media in MC - it shows as having no timecode track. Similarly the media in say MediaInfo shows as having no timecode track. If the media is opened via the AAF - are you suggesting that it would show as having a timecode track in MC?

  • Re: Adding Timecode Track to OPAtom

    Thanks - this makes sense for interplay check in - but for standalone media composer implementations this is obviously an issue. Are you able to suggest any other tools other than AMT we can use to add a timecode track? The media I am looking to support is JFIF 4:1s which is not a recognised essence type by such libs as libMXF and so I am not able to

  • Adding Timecode Track to OPAtom

    I am unable to see in the example app code - or any of the base libraries - where you are able to add a timecode track in to the new AMT clip that you are writing. I am doing AMT -> AMT encoding (uncompressed to compressed) where my source AMT asset has timecode both in the XML and on the OPAtom. My new files that I am generating do not contain any

    Do you have a copy of the sample app Visual Studio solution for VS 2015 / 2017? I am hitting across an issue when writing data where there is no audio source - that I can reproduce in the binary version of the sample app... ideo frame[278] written... video frame[279] written... video frame[280] written... video frame[281] written... video frame[282
