Approval web files have spilt in video
Having an issue with approval files compressed with flip4mac wmv, posted on the web. There is a split half way down the video footage, where part of the footage is “delayed” behind. The design has vertical moving bars, where the spilt it. Not sure if this is a fcp issue or a compression issue. Of course, changing the design, as that seems to cause it, would help, but is there a way to minimize the split? Looks fine on fcp and in NTSC. The FCP ftg is 8 Bit UC NTSC 16×9, we are in FCP 5.12 with a Kona. Not sure if this is a fcp issue or a compression issue. Rendered a .mov of a short clip of it, (it still has the issue)

Where are the graphics from, all created in fcp?

No After Effects, and those were lower field, but animation codec, with alpha. The sliding footage was in AE the talking head is FCP. Thanks

What codec are you using on the in that link?

Originally I used flip4mac through compressor, making a wmv file. The one you are looking at says it is a mov. It was exported from quicktime, it still says wmv in the properties and plays fine if you change the extension to wmv. I just shortened the original clip to put it up, somehow the extension was changed. It shows the same problem that I was having though.

How are you using Flip4Mac through Compressor? Why don’t you just export to WMV from inside FCP? Why is it coming up as a .mov when it’s supposed to be .wmv? Not working for me. The codec is unknown to QuickTime and the Windows Media Player won’t play it either.
All the best,

Jon,
I did a quick test and came up with the same problem. I don’t see anything basically wrong with your method. Export through Compressor should be OK. It looks like an encoding problem since anything that moves horizontally gets the halfway split. Can you pose this problem with Flip4Mac? Let us know if you find a solution.

Is your sequence interlaced, 720×486 anamorphic? So Flip4Mac is doing the deinterlace? Something seems to be wrong with that process.

I get a better result by first using Compressor’s Advanced Format conversion to deinterlace the clip and then compress that Quicktime with Compressor, using Flip4Mac. You can then change the options for the WM9 video compression to specify a progressive input and output frame. It takes quite a bit of time to do this with “Best” motion compensated deinterlacing, but it makes a big difference. There’s still a small flaw visible at the halfway point, but it’s tiny by comparison. You might try posting this questioin over on the Compression Techniques forum and see what you get. They might have some knowledge about why this deinterlacing step makes a difference. In general, I think you’re see a flaw in the encoder, or at least the particular version and implementation of it that you and I are using.
