Sequence Settings for footage shot on an iPhone
July 01, 2010 08:12AM
I'm making a web video for a friend and I am a bit rusty in my FCP skills.

When I drag the video to the time line, i get the red "needs to be rendered" bar across the top.

I've tried altering the sequence settings, but that hasn't helped. I want to be able to edit without having to render. As it stands now when I play from the time line without rendering i get a beeping sound and no audio from the track.

Aren't there sequence settings that I can use to eliminate this issue?

what are the specs of your footage?
most likely you will have to convert the footage to a more friendly format before your can edit it.
kind if a "pre-render".

If i remove the audio from the timeline, the render bar goes away. I am able to recreate the video specs no problem and they are:

1280 x 720, 29.97FPS H.264, 32-bit Floating Point, Alpha:None/Ignor, Composite: Normal, Pixel Asp: Square.

The only thing that I can't seem to change is the Audio spec. For the clips it says: 1 Mono.

I can't find where to set that within FCP to match. I'm assuming that is the problem.

Like I said, I remove the audio track or put it on mute in the timeline, and the render line goes away. That tells me it's an audio settings issue.

ok, life might be easier if you did convert that to a better codec for editing.

BUT...
if all you need to do is a simple cut down, maybe re-shuffle some shots, and export,
you can work with what you've got.

last time i got the red render for audio was when i was working with some DV Stream footage.
all i was doing was removing shots and trimming.
what i did was to render the audio of the whole clip in the timeline before i started trimming.
then FCP let me work quite freely.
unlike picture renders, i could trim and re-extend the audio without having to re-render it.


if you want to maybe grade and add effects,
then i think you would be better off converting before you edit.
use compressor to convert your footage to ProRes, or ProRes LT.


cheers,

Open it into the QT player and report on exactly what it says in movie inspector, especially about the audio. H.264 should be converted to something like ProRes LT. You can use Compressor or MPEG Streamclip to do this.

All the best,

Tom
