H.264 Choppy Playback

Alright.

I've had this ongoing problem for quite some time now and it's getting really annoying. My raw footage from my T3i plays choppy in Quicktime and stops/pixelates in VLC. However, it plays fine on Windows Media Player. The clips themselves edit and play fine in Premiere, but once I export the video in H.264 MP4, the problem begins again.

It's not my computer, I can play full HD videos just fine:

i7 Processor
6 GB Ram
Nvidia GeForce GT540M 1GB VRAM with latest drivers.

I already did this trick in VLC:

Go to Tools > Preferences
In the lower left of the box click the checkbox “Show settings – All”
Then go to Input & Codecs > Other Codecs > FFmpeg and look for the option called “Skip the loop filter for H.264 decoding”
Change it from “none” to “all”
Restart VLC

However it doesn't do anything to fix the problem. What gives?! Why is it that everything plays fine in WMP but not in anything else? The only reason I don't like using WMP is because of the contrast change in the videos. What am I doing wrong?

Can someone point in the right direction?

P.S. I have the latest K-Lite codec pack installed.
 
It's obviously a software issue. You'd need to get a player that can work properly with that footage. I've given up trying: the clips edit fine, and I know what software to use in the final export in order to get files that play perfectly, so it's not a problem for me if the original clips don't play fine outside the editor. BTW: my final export is done with handbrake, which creates H.264 codec with mkv format that play perfectly nearly everywhere; I also use it for the original clips if I want to show one to somebody outside the editor.

I can't say why this 'plays' better in one tool or another. I would suggest opening up VLC and using the Window->Media Information window to check the bit rate of the media you are trying to play. If it is 100 Mbs... probably that could explain why it is erratic... doesn't explain why the Windows widget plays smoother... other than perhaps hiding the dropped frames better...

Also are you playing off of a USB device? If so, check playing off the system 'internal' drive.

In terms of bit rates, broadcast HD is around 20 Mbs.

There is also the issue of disk fragmentation, and perhaps the Windows widget creates a bigger buffer, and allows the vagaries of disk fragmentation to be less obvious. I'm told that modern OS's aren't as sensitive to disk fragmentation as days of yore... but sometimes I wonder about that...

Try Media Player Classic. Also, you should be able to remove the sRGB overlay that your graphics card adds to video playback through your cards software interface.

Yes! Finally! Media Player Classic x64 did the job! Thank you!

How exactly do I go about using handbrake as a final export if I'm on Premiere? Should I render out uncompressed then send that to Handbrake?
