Working With 720p

[Ron B]

I have some .mp4 1280x720 60fps footage shot on a GoPro camera that I can't seem to do much with. I have Premiere CS4 and Vegas 9 but neither one seems to be able to produce anything I can use. With the 1920x1080 footage from the GoPro, I usually convert it to Microsoft AVI with Vegas, then edit in Premiere. With the final edited AVI file from Premiere I can convert it to FLV, MPEG or MP4. The 720p doesn't seem to convert to 1080i very well.
Any tips on working with the 720p footage?

AviSynth 720p60 to 1080i30 conversion:

DirectShowSource("filename.mp4")
AssumeTFF()
BicubicResize(1920,1080)
SeparateFields()
SelectEvery(4,0,3)
Weave()

Thanks jagabo, I'll check that out. I looked at AviSynth in the past but got scared off because I'm not a scripting expert.
Good time to learn, I reckon.

The ".mp4" I'm working with is actually H264 in an MP4 wrapper. When I use the AviSynth script posted above, it doesn't work. I'm assuming I need to work with FFmpeg or something other than DirectShow.
Just a bit of wandering around as I try to get the hang of AviSynth.

You need to fix your directshow system .

On windows7 use win7dsfiltertweaker, ffdshow, haali media splitter

Or you can use another source filter, ffmpegsource2

FFMpegSource2("video.mp4", atrack=-1)

That sounds like the ticket. A lot of little quirks with Win 7, especially the 64 bit model.
Thanks.

The problem with 64 bit Windows is that there are two separate video systems -- one for 32 bit programs, one for 64 bit programs. A filter installed in the 32 bit system cannot be used by 64 bit programs, and vice versa. And within those two systems there are separate DirectShow and VFW systems. And 32 bit installers often install their components in the wrong folder making them inaccessible to both 32 bit and 64 bit programs!
