    Sound Normalization is also important. In Germany we use EBU R128. But nothing is perfect. Unfortunately, every TV channel still has some little things that are a little different from the norm.

    • @skycron

      Very true, on all accounts. EBU R128 is a great specification - in my view it should be mandatory, but eh. Germany has always been ahead of the curve with broadcast specification and technology in general.

    Great video! I am strugling with getting the proper Bit Rate for my video. Is there anyway to change the Bit Rate setting when exporting a .MXF file?

    • @skycron
      @skycron  9 месяцев назад

      The bit rate is in the preset- for broadcast you are always going to be 8 bit.

    Hey my Friend, I just found your channel and it was already really helpful! Thanks so much. I also watched your Multichannel-Video but I'm still a bit confused. Maybe you can help me out. I'm in Europe by the way and it's about a 25s Commercial.
    The Broadcaster has the following requirements:
    [MXF OP1a + 8 CH Audio (24 Bit)] Video codec type: MPEG-2 (XDCAM HD 4:2:2) 50MBit
    File extension (container): .mxf (MXF OP1a)
    Data reduction: XDCAM HD 422
    Data rate: 50 Mbit/s
    Interlacing: Interlaced
    Audio tracks: 8 (1+2 German broadcast tone, 3-8 silence)
    Audio bit depth: 24
    Audio Sample Rate: 48KHz
    Program Loudness: Short Term Loudness maximum -18 LUFS (+5LU)
    The Videopart is clear for me after watching your video (I only change the codec to the correct PAL one)
    But the Audio still confuses me. I got a premixed Stereofile after ebuR128-standards (so -23LUFS).
    Am I right that I have to split this Stereofile into two monofiles (Channel 1 is L and Channel 2 is R)?
    So I don't just put the one Stereofile on 1 and 2, right? And then I just leave Channel 3-8 empty.
    And my next problem is...I checked the LUFS with the Loudness Radar in Premiere and before exporting everything seems correct (so -23 LUFS) but when I import the exported MXF File into Premiere and check the Loudness again it comes out as -20LUFS.
    I have googled this problem and a few other people seem to have it too but I didn't found a real solution for that.
    Maybe you can help me out? THANK YOU so much in Advance. It's my first Broadcast-Delivery and I don't want to make any mistakes :)

      Hi Michael, glad it helped you. Please consider subscribing to the channel if you haven't already as it really helps us out! To answer your questions:
      1) For the audio, yes, you have to split your stereo master file into two mono files, one for the left channel and one for the right channels. I have a tutorial for that, which it appears you've seen. Put the L channel file you made in Track 1 and Track 7. Put the R channel file in Track 2 and Track 8. Leave tracks 4-6 blank.
      2) There is a bug in Premiere where it exports at -3db off. It drives me crazy as they haven't fixed it. The workaround is to export 3db higher so it imports at the correct loudness level. So export it at 26db and it should import at 23. It's stupid, but it'll solve your problems.
      Also, broadcasters - particularly in Europe - are generally pretty understanding if it's your first attempt sending these kinds of files. It's when they've known you long enough that you should know better that they start getting cranky.
      Hope that helps! -Cory

      @@skycron Hey Cory, thanks so much for your fast answer. I'm glad to hear it's just a bug, that means I was on the right track haha.
      But I still don't get the Audiopart with Track 7 and 8...why do I have to do that if they state in the specs that Channel 3-8 has to be silent?
      But yeah, I'm sure they are understanding but doing it right upfront is my preffered way to go ;)

    • @skycron
      @skycron  Год назад +2

      Oh. That part I didn't see. If the broadcaster says they want 7 and 8 silent, listen to them. Just put it in one and two. A lot of broadcasters want the stereo duplicated in 7-8 if it isn't a surround mix. Don't worry about 7-8.

      @@skycron Hey, me again ;) I'm still a bit confused, so I thought maybe you can help again. I followed your notes, exported the file with -26 LUFS and yes, when I import the file in Premiere again and check it with the loudness radar (and also with the youlean Plugin) it shows -23LUFS. BUT: when I for example export just the WAV-File of the Audio and check it, it still is -26db. Why is this happening? I ask because I sent the MXF Masterfile to a collegue of mine who works in a Post Production house and he said the File is 3db to quiet. His Workflow was this: Import into ProTools - sound extracted - made stereo file - and measured it. The result is -26, i.e. 3db too quiet
      So now I'm confused again and he said that my measurements are maybe wrong. I already sent the file to the broadcaster yesterday and till now, no complains.Thanks!

    • @skycron
      @skycron  Год назад

      Hi Michael, there is actually a bug in Premiere where it exports incorrectly by -3 dB. Adobe hasn't fixed it. The solution is to adjust your levels by the exact amount Premiere is adjusting it. It's stupid that this should even be done given what Adobe charges for the suite, but it'll work. Bring the files down to -20dB and you should be good. Maka sure you do this for each audio channel in the Mixer (1, 2,). Don't do it with the master volume expecting it to apply it - Premiere will ignore it. You have to actually do it to each audio channel. This bug is frequent enough I will probably do a tutorial on how to fix it because I get this question probably once every couple of weeks.
      Also, you need to make sure the files you made in Audition are metering correctly. So bring your mono L/R files down compensating for the dB differential too, since Premiere will double up on the mistake. I feel you on this one, the first time I encountered this bug years ago it was driving me crazy. Just keep jigging with it until it meters properly.

    Thank you SO much for this tutorial! Very concise and a huge time saver. Quick question for you: if my sequence is 23.976, but the network is asking for 29.97, are there any adjustments I should make from the parameters that you originally shared here? I don't love the idea of upconverting to a higher frame rate, so I'm a bit nervous about potential loss of quality.

    • @skycron
      @skycron  10 месяцев назад

      Glad it helped! To answer your question: all you do is apply a 3:2 pulldown! I have a tutorial for that here: ruclips.net/video/AgCZFnTH2j8/видео.html . If you follow that you will have a perfect 23.976 > 29.97 file ready for MXF ingest! -Cory

    This was soooo helpful!! Thank you so much for this. I do have a question though. We are shooting our first commercial for TV broadcast now. We have a spec sheet from them and it all aligns with what you have here. Except it says excepted output format 1080i 59.94fps. Can we still deliver the same 29.97 you have here to them? Or do we have to deliver 59.94fps, and how would we pick that? I noticed you picked XDCAM 60i - is that what they mean?
    Thoughts?

    • @skycron
      @skycron  Год назад +1

      Glad it helped! Yeah, pick XDCAM 60i. Without going too techy on you, basically 59.94 resolves to the same as 29.97 and when broadcast works out to the same. Sometimes even broadcaster spec sheets are written by boneheads. You should be good. There isn't a Canadian broadcaster around that will reject you on QC with these specs. It'll go in like butter. Rogers, Bell, Corus. Will work fine.
      Noticed you guys were in Victoria - we deliver Go/Nitro weekly to CHEK using these specs without a hitch. Bell Media uses the same specs so I was delivering to CTV/TSN with no QC issues. Cool stuff with the motorsports stuff, we always enjoyed working with NASCAR when we filmed at the Pinty's. -Cory

    Hey, just a quick question, when exporting you had the audio channels upto 8, does that mean when you edit you need to copy your audio on 8 different audio tracks as well?

    • @skycron
      @skycron  Год назад

      No - but I have a set of tutorials that walks you through it. Your program audio should already be mastered and ready from picture lock. Export your master audio in stereo, then follow these tutorials to prep the audio files to insert correctly into each channel:

      You also need to make sure you route your audio 1-2, 3-4, 5-6, 7-8. Keep in mind when you play the file it will sound mono. Go by the routing in the timeline. Follow this tutorial I've linked for you here. You have to prep your audio in Audition like this: ruclips.net/video/ZGOTOaqiQAo/видео.html

    • @skycron
      @skycron  Год назад +1

      Your audio routing is determined when you set up the actual multichannel project, not when you export. In the basic audio settings, in advanced it will give you the option to go Channels: 8. But you have to have routed the audio correctly when you set up your project, first.

    Hey dude, great tutorial, very helpful. One question for ya.
    We're producing some t.v content that requires:
    Format - MXF, Bit rate: 8 Frame size - 1920 x 1080, Frames per Second - 29.97 Field Handling - Interlaced upper field first.
    My question is in regards to the "Bit rate: 8" requirement the broadcaster needs. Does this mean we need to shoot in 8-bit?
    Thanks.

    • @skycron
      @skycron  Год назад +1

      Nah, you don't have to shoot in 8-bit. When you export in XDCAM MXF as in the tutorial it'll deliver in 8-bit as that's part of the preset spec. So your resulting MXF will be 8-bit.
      Very rarely do we shoot in 10-bit unless we were dealing with VFX/greenscreen with a lot of motion tracking requiring the extra luminance. It's just deadweight that makes for bigger files with more data than you need 9 times out of ten.
