Do I have to deinterlace AVCHD footage from Vixia?
on Apr 3, 2013 at 2:36:09 am

Canon Vixia HF M500.
AVCHD.
Final Cut Pro X.

Do I have to manually deinterlace before or while using Final Cut Pro X, or does FCPX do it for me?

Thank you.
Alphonse

Why would it deinterlace it? Why do you want to?

>Why would it deinterlace it? Why do you want to?

Because I don't know what the "heck" I'm doing and I read elsewhere on the Internet that deinterlaced 60i movies look much better than the 60i movies that the Vixia spits out, so you should deinterlace it before editing it. I "assume" that if this is true, FCPX will deinterlace it for me. I'm asking because I want to know if it is true, and if so, does FCPX do it automatically.

Thanks,
Alphonse

You must deinterlace if you want your movie to be played on progressive screens (computers).
If you are going broadcast or Bluray, you don't need to de-interlace.


[Alphonse Breaux] "I read elsewhere on the Internet that deinterlaced 60i movies look much better than the 60i movies that the Vixia spits out,"
That's not true.
Deinterlacing you are dropping half of the original picture information, and you lose half of the temporal resolution. It always will make movement less smooth.

FCPX will automatically deinterlace the stuff if you drop it on a progressive project.

The 480i stuff I used in a 1080p project was not deinterlaced automatically. Have to go to inspector and turn on deinterlacing if that's the case.

X deinterlacing looks great though.

That said, don't do that. Edit interlaced. When you're done you'll have an interlaced version. Then export that via
the YouTube setting or compressor, etc. Deinterlace at that point.

You haven't mentioned your shooting mode.
The Canon Vixia/Legria can shoot in a progressive mode which is a form of PsF. FCPX will identify it as interlaced but it will look progressive.

I shoot AVCHD in MXD mode.

I'm sorry, that's MXP mode, not MXD.

Wow! This is crazy!
So if I want everyone I know to have a good copy of my video I must:
Render a Master File copy for archive.
Render an SD copy for DVD players.
Render an HD copy for BR players.
Render an interlaced copy for those with old TV's.
Render a deinterlaced copy for those with flat-panel TV's.
Render a copy for Youtube.

Or, I guess I could just put it on Youtube and hope they all have Internet!

Thanks for the help,
Alphonse

[Alphonse Breaux] "Render a deinterlaced copy for those with flat-panel TV's."
TVs (flat-panel or not), are Interlaced.

[Alphonse Breaux] "Or, I guess I could just put it on Youtube and hope they all have Internet!"
That will be the best, but don't forget to de-interlace.

Don't forget copies for tablets and smartphones.
This is why you can set up to encode to multiple targets in FCPX and if you need to make custom settings in Compressor, FCPX can use those as well.

[Alphonse Breaux] "Or, I guess I could just put it on Youtube and hope they all have Internet!"

Which is why so many people deliver to YouTube... which will also encode to several different sizes/datarates which can be chosen by the viewer based on one's connection speed.

The ONLY one you would deinterlace would be YouTube because its a computer monitor.

First, I want to thank all the people that replied to this post for the information provided.
Now I have a series of yes or no questions (but you can elaborate if desired):
1) Did all inexpensive, older consumer video cameras (before hi-def and 24p) shoot interlaced or progressive?
2) And did the inexpensive, older consumer video editing software have an option for interlaced vs deinterlaced?
3) I had a few video cameras years back (video tape) and don't remember having an option to shoot or edit interlaced vs deinterlaced.
4) So I am curious about watching the videos that were edited back then on my (new, at the time) flat-panel computer monitor and on my old CRT TV.
5) I DO remember that the edited video looked better on the TV than on the flat-panel monitor (mainly color - not jaggies), but no one was talking about interlaced vs deinterlaced (or if they were, I didn't hear them). I guess that the lower quality of the video and the TV's and monitors back then is the reason.
6) And now, the MOST IMPORTANT QUESTION: My camera shoots "AVCHD MXP or FXP for better quality or LP for longer recording times" and "MP4 for smaller file sizes and faster uploads." Are the FXP, LP, and MP4 modes interlaced or deinterlaced?
Thanks again for the help,
Alphonse

I feel like an idiot. I just found a new screen on the camera (only when shooting in "Manual" mode) that allows me to shoot 24p or 30p in addition to the default modes. The screen was in a tabbed interface and was behind another tab. None of this was mentioned in the manual!
Thanks again,
Alphonse
