Bad compression on fast-motion video

[Rafael Amador]

hi Paul,
Which setting are you using in the H264 compressor?

Are you working w/interlaced footage, is your Canvas window set to 100%, and are you viewing this on a broadcast monitor?

So where’s the sample?

All the best,

I’m using the H.264 in the Quicktime export option. Is that what you mean by setting?

[Paul Ravillino]

I think the footage is interlaced? I’m not sure. I imported it from mini DV tape, into a regular NTSC timeline. How can I find out if it’s interlaced?

The video in question is right at the beginning.

Once again, details need to be given.

How was this shot? This looks like pull down that you find on a DVX/HVX shot at 24p onto tape. If so this is a import, not an export problem.

I would be surprised if this is on the sequence footage in FCP but you are not using an external monitor and your canvas is NOT set to 100%, which would cause this problem to be hidden from you.

It may also be introduced when you are adding the speed changes to the clip, was again you need to be viewing your FCP timeline on an external monitor, only way to catch these things.

That being said, exporting a ref movie (or self contained movie) from FCP and then taking that into Compressor, gives you more control and in the end better quality.

You should also take the time to learn general terms of our industry, no crime in not knowing what “interlaced” means but our first response should be to look it up and not ask what it is.

If it’s going for b’cast you have to judge the image on a monitor that will properly display interlaced video (such as a broadcast CRT monitor). You can’t properly judge the image by viewing it on your computer monitor.

Does the network/channel you are delivering to really specify h.264 as the codec it wants?

Okay, it looks good on a TV monitor… I didn’t realize that a computer monitor would be that different.

They didn’t specify that I compress it using H.264. They didn’t specify anything. I assumed H.264 would work well. Is there a better way to do it for TV?

Thanks!

You might try deinterlacing the footage first…
Effects>Video Filters>Video>De-interlace

Also, make sure you have Frame Blending checked in the Time Remap section of the motion tab for your footage.
