how to compress 1080i sequence for progressive output to YouTube?

[Richard Cooper]

If your final output is a progressive format then I would copy your edit into a progressing time line (DVCProHD 1080p/30 or ProRes and just use the de-interlace filter on the interlaced footage.

Or de-interlace upon output to h.264 from your existing sequence.

Either way you will want to de-interlace before you upload for web.

Good Luck!

Well, that actually depends upon the pixel dimensions of your Youtube video. If you export at 50% or less than your present dimensions, there is no need to deinterlace. It’s essentially done for you by squeezing the scan lines together in half the space.

[Greg Hammons] “I am seeing interlacing when projecting timeline on Panasonic HD monitor.”

Can you please explain that statement? There are two things in that sentence that do not compute:

1) seeing interlacing? If you’re seeing the interlace on a TV or video monitor, not a computer monitor, something is wrong, because they are designed to display interlaced video signals. How are you feeding your video signal to the monitor?

2) “projecting” on Panasonic HD monitor? What does that mean?

Thanks for the info David… it makes sense…
I was assuming HD resolutions for upload. I don’t even bother with anything less than 720p.

Cheers!

Hey Richard,

I’ve found that lots of people I know, with lesser computers than the ones we use, often get stuttering during playback on both Vimeo and Youtube at 720p. So, I seldom use anything that big, though I would like to.

David, Thank you for the information….to answer your questions

1) seeing interlacing? If you’re seeing the interlace on a TV or video monitor, not a computer monitor, something is wrong, because they are designed to display interlaced video signals. How are you feeding your video signal to the monitor?
I have a Kona LHe card sending to a Panasonic BT_LH1700W HD LCD monitor through SDI (Video format on Kona control panel set at 1080i29.97).

Here is a FF on the interlacing I am seeing on the timeline.

2) “projecting” on Panasonic HD monitor? What does that mean?
Sorry, my inexperience…. what I meant was viewing on HD monitor (as described above)

David,
Could you explain your settings for H.264 and upload settings for YouTube, that you use?

Thank you,
Greg Hammons

You certainly are seeing the interlace there Greg. That sure looks as if the fields are reversed. Double click on one of those clips and see if there’s a switch fields filter that somehow got added by mistake.

The setting that I use for Youtube, if HD is the goal, is one of the high quality presets in Compressor that yields a 1280×720 h.264 – it’s in the settings listed as Apple>>Other Workflows>>Web>>Download>>QT 7 Compatible>>h.264 800kbps. You can raise bitrate to whatever you’d like, it will just take longer to upload. But, you can experiment and raise it up to 2 to 3000kbps if you want. Youtube will squeeze it for you to their delight.

Or, you can go to their site and read their specs, I think they have some recommendations for files that don’t need recompression now, but I don’t use them.

David,
I checked on several clips and no filter has been applied. I also checked that the field dominance for the clips was the same as sequence settings. When I double click on some clips both (1080i60 and 1080p30), and look under the Filters>video Filters tab, a “Mono 1 Filters” is found, but no filter is under that??? I experimented with adding a de-interlace filter and that seemed to remove the interlace lines that I was seeing. I have read that one should not use the de-interlace filters in FCP or Compressor, so I removed it and the interlacing comes back.
I am only seeing the interlacing in 1080i60 clips at this point.
