Hello to all!
I was wondering. i have been working on a project using both final cut pro and motion. The footage was filmed on sony Z1 and shot in PAL -dv. I have been adding text into the sections of the project and have simply been sending it from final cut to motion making the changes then sending it back. All was going well until the output. When i export the footage out and deinterlace the project for web use everything looks great apart form the text. I have managed to correct this by removing the field dominace of the entire time line and export as a "progressive" project. (Which i expected to be great for web but not for tv)
My question is that the final export i did worked well and looks great on both the web/projector and also on my tv!! why is this? and what problems am i not seeing from dropping the field domiance of the project?
Thanks
Field dominance doesn't matter if you de-interlace. It's relevant only if you're going to display on a real tv set, witha crt display, one that has no image processing. All flat panels have deinterlacers and scalers, and if properly designed, they are not affected by the field order. I've recently been doing tests on displays for just this purpose, and devising test signals to check them.
hi Alan,
When i changed the field dominace to none i did not deinterlace the output. Are you saying that when i watched it on my TV the dvd player was doing something to the progressive file to display it correctly on the TV?
Wait a minute, I'm confused.
Field order is irrelevant in a progressive project, because nothing's interlaced, and therefore the de-interlacer in a display panel either has nothing to do or makes no difference when it does it. Field order matters only in an interlaced project, but, again, only if the footage starts out interlaced.
How did you shoot it? Progressive or interlaced?
Most progressive projects edited by broadcasters use progessive footage, edit progressive, but then add any rolling titles in interlace to get the motion smooth. The output is then recorded as though interlaced, even though the footage is progressive. That's the way we've been doing it for around 50 years, and it seems to work.
Im confused to!!
The footage was shot on a Sony Z1 DV - PAL so is interlaced?. If i change the fields to none what is this doing to my interlaced footage?
All i know is the result looks better for both text and picture when i remove the fields. both on a tv and monitor.
Z1 in SD is interlaced if that's what you set it to, it's your call. PAL is always interlaced, there's no other possibility, it;s in the standards, but it can carry a progressive image if you set the camera and the project to progressive, but it always travels as an interlaced signal, it can't possibly do anything else.
I've no idea what you mean by "remove the fields". A frame of SD (and HD, with one exception) is comprised of two interlaced fields. Each is a new exposure, but the lines of each field interlace with the lines of another field, two of which fit into a single frame. If you delete any fields, you have half ved the image rate, and halved the vertical resolution. Nothing else makes sense.
Hi,
Im confused so lets start from the top i f i may.
If im producing a video for display on both tv and web. It is going to involve the use of moving text using Apple motion and editing in final cut pro studio 2. I am shooting on a Sony hvr Z1e. what would be my best method of workflow in order to get the best result with crisp text. (its the text im having problems with on export)
Will i have to export to separate videos? one for web and one for tv? and will this involve to different work flows throughtout?
Hi
Your Motion graphics can be exported as either interlaced or progressive.
If you import the Motion project into an FCP timeline , then depending on the sequence frame dominance settings - and the codec, you can render out interlaced or fully progressive versions of your titles.
If you use a codec like ProRes, which can be either, then you avoid the psf format that the DV-PAL codec gives you for non-interlaced movies.
The best deinterlacer is Compressor, with Frame Controls on, and set to Best. This will be a long render, but will merge the two fields with minimal combing.
Whether this is worth the effort for a web movie depends on the resolution you will use for your web movie.
I'll leave you in Paul's capable hands, he knows FCP, I don't.
cheers for both your help. Ill give it a go and see how i get one.
I've no idea what you mean by "remove the fields".
My guess is that this is a setting which applies to the re-renderering of frames when the text is overlayed. PAL DV is always lower field first (apart from Matrox!) and if footage never needs to be re-rendered it will still be lower-field first on output, but adding a text overlay will cause the frames to be re-renderered and I think it is *then* that the field dominance setting comes into play.
I suspect that "removing the fields" means setting no field dominance (i.e. frames are progressive) and the frames are then re-rendered as progressive. The footage itself won't be deinterlaced (and will still display as interlaced), but the text will be overlayed as if it was progressive - i.e. moving text will move in frame (not field) increments.
