1080 60p downloadable files
OK, I made some test files with Vegas Pro 10 Trial from my HDC-TM700 from the Native 1080 60p .mts format, rendered to 1080 60p .WMV and one .MP4. It’s a fast moving video to show off the 60p.
The .WMV videos were rendered as 1080 60p 25 mbs where the .MP4 was only rendered at 1080 60p 10 mbs. Someone asked me, why do I still use the out dated .WMV format, well this is why.
First of all these downloads will only playback smoothly on a quad core machine due to the 60p I think. The .WMV files all play smoothly on my i7 at the 25 mbs bitrate, where the .MP4 stutters, even though the bitrate is only 10 mbs. I may be missing something in my render settings that caused it, so feel free to go to Vimeo and search, TM-700 and download a native 1080 60p .mts file from this camera and test it yourself. If you can get better results with the MP4 format, please let me know how you did it.
There’s also a 1080 30p wmv to compare to the 60p and one more 1080 60p wmv of a tiger,which I downloaded from Vimeo, just to show you the quality of this $759 cameras picture.
I also used the new stabilize feature too, still shows some shake but compaired to the original it’s like night and day. I had just got the camera and was going about 25 mph on a small boat, with a hand held camera that weighs about a pound. Not the best environment to get a steady shot.1080 60p wmv

Stuttering on AVC playback rarely if ever has anything to do with the bitrate. It’s the decoding complexity… AVC is more complex than pretty much anything else you’re going to run into. WMV/VC-1 is different enough that it’ll play on systems that might be a bit challenged by AVC.
So I tried the MP4 version on my system… smooth as silk in Windows Media Player. This is a Core2 Quad System, Q9550 CPU, 2.83GHz, nVidia 8800GT CPU… nothing all that recent. The CPU peaked at 17%, but stayed around 12% most of the time. This is playing fullscreen on a 1200p monitor. Played it again in Splash Lite, pretty much identical results. I shut off GPU acceleration, played it in Splash Lite… still silky smooth, but now peaking at about 50% CPU use. And man… going to 10Mb/s sure crapifies the video, compared to the usual 28Mb/s, probably more than usual, since this is high motion footage.
I tried it in VLC… that’s usually the way to get bad AVC playback. It stuttered a little, but actually not too shabby, and peaked at about 45% CPU. VLC is probably better than usual — I think higher bitrates, not the AVC decoding pre se, are its main issue.
Let’s see.. played it in Nero MediaHub (replacement for Nero Showtime). It jumped badly with video acceleration enabled… that’s weird. Worked just fine, with about 45% CPU use, with acceleration disabled. Played it in QuickTime… 60% CPU, worst of all, but just as smooth as the others, all 60fps.
I tried the MP4 in WMP on my laptop (Quad Core2 Duo, 2.4GHz, nVidia 8600M GPU)… played smooth as silk, all 60fps. Peaks at about 60% CPU… seems a little high for GPU-accelerated playback, but whatever… it played just dandy.
You definitely have a problem somewhere.
