Yep I can set it fairly easily – I was hoping to keep a selection of presets that I can carry around with me…

I guess it’ll be a feature request then 😉

If it’s any help I’m using Butler macros to do a similar thing.

I have 2 sequences open – SOURCE: synced interview and DEST: quote selects sequence

I mark in and out on the source sequence and have Butler do macro 1:

Save (CMD-S) (so I can easily undo!)
Go to Out, Add Edit (Shift O, CTL v)
Go to In, Add Edit (Shift I, CTL v)
Mark Clip (x)
Select between Marks (alt-a)
Add marker and edit (m,m)

Then I enter some details in the marker and run a 2nd macro

Enter
Go to Out (down arrow)
Extend marker (alt – `)
Copy (it’s still selected above) (CMD-C)
Switch to other sequence (Shift CMD ])
Go to end of sequence (END)
Paste(CMD-v)
Clear Marks, Clear Selection (Alt-x, Shift-alt-a)
Switch back to source sequence (Shift CMD [)
Clear Marks, Clear Selection (Alt-x, Shift-alt-a)

Now ready for next quote to be marked.
Sounds convoluted, but it’s actually pretty slick and I can see the sections of interview in the source sequences that have already been used.

Not in this instance… making H264 viewing quicktimes from DVCProHD sequences. Why do you ask?

Preset I’m using, FYI, is:
Compression H264, Multipass and B-Frames enabled (runs in background)
100% quality
Limit data to 400 KB/Sec (adjust to make size about 90MB and it’ll turn out under 100MB)
IMA4:1 audio Stereo / Auto
640 x 360 Deinterlace Video enabled
Upper Field First
No Rotation

Sorry, I realise it’s not FCP but lots of folks use MPEG streamclip to render proxies or transcode footage.

I’ve made the copy manually 😉

OK a bit more of a logical approach got me to the solution…
“Some idiot” had enabled ‘VANC’ in the Primary Format tab.
Disabling VANC gets rid of the green flashes / audio pops and I’ve only ever used VANC for RP188 timecode… which does beg another question…

[Jeremy Garchow] “Let’s chase down what the hell is it you are trying to test. No offense, but this is a mess.

Hi Jeremy

No offence taken, I’d noticed some green flashing on downconverts when testing in an SD environment – so I was trying to test out as much as I could whilst in a room with a Tek HD scope with limited time. Main testing was 2 hour long captures and playback of ProRes SD ensuring frames not dropped (successful).

Why not use a real HD clip when testing HD outputs?

Source was an SD VTR – this is a likely workflow scenario for me – captured SD footage mixed in an HD timeline with outputs to SD. I did get the green flashes in the original SD downconvert tests with generated HD clips, this is why I was trying different HD flavours.

What scratch drive are you testing?
FW800 single drives – non raided but reporting good enough figures with AJA test. 56.9 MB/s read 79.7 MB/s write. Wouldn’t expect to use this in the real world but should be plenty for ProRes HQ single stream playback. And lack of speed would be dropped frames rather than green flashes I would think?

What easy setup have you chosen?
I am switching to AJA installed ones. 1080/50i and DVCProHD or ProRes or ProRes HD or XDCam 422 HD CBR as appropriate – checking seq settings before playback etc.

Have you opened the Control Panel yet?
Yes.

[Trevor Asquerthian] “AJA Digital out set to SD (i.e. downconvert) ”

THis isn’t the way a downconvert works on AJA products. You leave FCp in the proper Hd easy setup (with matching HD footage/frame rate timeline) then use the Koan control panel to downconvert (set output to secondary and appropriate NTSC/PAL frame rate that is based off of your HD timeline).”

That’s what I’m doing, I removed that whole explanation from my post as I thought it was too obvious 😉

Correct easy setup selected. Sequence matches easy setup. Primary output 1080/50i, Secondary output 625/50i, Digital Out set to Secondary output – control panel shows ‘downconvert’.

The thing I need to find out next, I think, is are the green flashes caused by IO Express or FCP. If FCP then I would have thought they would be apparent on laptop display? I guess I’ll see if AJA TV generates the same errors.

I’ll start with clips that are native to the timeline I’m testing too!

Thanks for your help on this…

I’ve also discovered that I get green flashes when downconverting a ProRes422 timeline.

[Trevor Asquerthian]

I’ve now seen this too many times in too many different setups.

Recapturing is not an option often – no deck available, tape in a different country – or the media was tapeless to begin with.

I suspect it is down to the inherent non frame-based nature of quicktime.

One manifestation I have now seen twice is where I have revealed part of a clip that means that it is now partially rendered. The unrendered (green preview) section plays and then does a jump cut to the rendered section.

Then U to toggle sides of the edit – there isn’t a select outgoing / incoming / both like Avid AIUI.
