broadcast monitor playback
on Oct 27, 2009 at 3:49:38 pm

Hi,

In my company we have many edit suites of FCP with kona LH.
we usually face problem.
my self didn't face with the blackmagic..

when we import any QT file (for example) H.264.
then insert it in sequence of aja HD uncompressed.
it gives red bar for render!
when we render it and play it back!
it doesn't play on broadcast monitor!

So i import this H264 (for example)into new sequence.
then i click OK for the dialogue to make the sequence same acid of the file..
then hit play!
no play on broadcast monitor!


so i found solution for it that i open the clip in QT player then RExport it to QT apple prores or any aja codec file..then it plays fine on the broadcast monitor..

i see this is crazy especially if long time file...

this problem happen in all FCP suites we have(4 suites)
for any QT i put on the timeline created by codec different than prores or aja..
(animation,none,h264,pal....)

in the blackmagic it was not happen!
so where is the problem??

best regards

[ayman abdel-basset] "so where is the problem?? "

FCP does not support rt playback of codecs that aren't supported by the suite, such as h264. h264 is a web delivery codec, not an editing codec. You need to conform all video to something that is enabled in FCPs rt engine.

Jeremy,
thank you for your reply!

but i guess you didn't read all of my post..

same problem happen when i add animation codec or any other codec than prores or aja acids..

i gave H264 as sample..
and FYI any codec you add on sequence it should render to the codec of the sequence and play on the broadcast monitor..

in my case it renders..but no way to play on broadcast monitor.

Animation is not an editing codec either.

Animation isn't a real time capable codec either. You need ot place the movie in a timeloine that has a standrd video codec, render and then you should have rt playback. If oyu son't, that's becuase your timeline and video output aren't matching.

Hi,

thanks for your reply..
i do know this..

BUT with my experience with Blackmagic when i add animation codec movie on timeline with native codec of the video card..
it gives me red bar (which mean your say)..but when i render this it goes real time!

because i need animation codec on timeline line for alpha..

that doesn't happen in the aja..

hope you could get what i mean!!

RIght, so the proper way to do this is to select the proper easy setup from the easy setup menu (control-q).

Then make a new sequence.

Then drag one of your files to the sequence and when it asks if you want to change the sequence to confrom to the clip, you say NO.

Then you render, then you playout in rt.

It's pretty easy, Ayman. What format are you working in?

[ayman abdel-basset] "let's say uncompressed 10bit "

And I'll assume SD PAL.

So hit control-q and choose the AJA Kona PAL uncompressed 10 bit easy setup.

Make a new sequence (very important).

Drag the footage to that timeline, and when FCP asks if you want to confrom the sequence to the clip, say NO!

Render, and playback.

Jeremy

Thank you for your reply,
i figured the problem..
that i work HD and the aja kona sequence presets to play on broadcast monitor hasn't all codecs of the QT again i mean HD..

animation,H264 is not of them!

so i should from begin work with the codecs found in the presets or render any other codec for one of this presets..

thank you ,

[Jeremy Garchow] "FCP does not support rt playback of codecs that aren't supported by the suite, such as h264. h264 is a web delivery codec, not an editing codec. "

And this is getting less clear all the time. Right now, the h264 clips from a 5D or 7D Canon can be thrown onto the FCP timeline, and if you say yes when asked if you want the sequence to be changed to match the clips, they play on the FCP timeline in realtime without rendering. So, somewhere deep inside, FCP has this ability and a codec for h264 playback.

Of course the Kona can't play through to the monitors, so it's a hollow victory.

I guess at the end of the day, we have to define what an editing codec is, or perhaps it's being redefined for us?

The proper workflow for H.264 originated material is to convert it to something like ProRes or ProResHQ prior to dropping it into the timeline. You can use compressor for this.

WEll yes, that's because the clip and timeline codec match. Now, try to do a cross dissolve, a 3 way cc, or whatever, and you will see just how non rt it is. Most likely, those clips are RGB, so when does the conversion to YUV happen?

[Mitch Ives] "I guess at the end of the day, we have to define what an editing codec is, or perhaps it's being redefined for us?"

An editing codec in FCP terms, is a codec that has real time effects and real time playback in the FCP timeline out of a capture card. Something that could be played back and assemble edited to tape in real time without a render would be a couple of other requirements.

My point was that they can even play at all. I wouldn't try to edit that way, but I find it interesting that it can find something (a codec) that I cannot locate manually that will play this? One wonders if Apple could build on this, especially since it appears Avid can edit these files natively (haven't verified it myself).

An h264 file? An iPhone can play an h264 file. That's not the challenge.

[Mitch Ives] "One wonders if Apple could build on this, "

Yeah, it's called iFrame and it's coming to iMovie.

[Mitch Ives] "especially since it appears Avid can edit these files natively (haven't verified it myself). "

Avid usually transcodes files upon import, a process very different to FCP. At that point, you aren't playing back h264 files, but rather Avid codec files.
