i shoot with a 7d and mark ii, edit with sony vegas. i cannot stand the choppy playback, it forces me to render a video to check how things flow/are in sync. do not even try to tell me there are fixes for this, i've tried them all!!! i need some software that i can playback smoothly at any point durring editing, are there any out there?

also, don't say its my laptop either, i have 8 g ram, i've eliminated all other possibilities, other vegas users can chime in to verify lol

Premiere Pro CS5 has the mercury playback engine for realtime editing. It only works with Nvidia cards though.

Which version Vegas?

Vegas 10 is the only version that will do smooth playback. Most laptop w/ dual core w/ 4GB RAM can process smoothly nowadays. I have a laptop with 2.6ghz(IIRC) intel i5 w/ 4GB RAM using external HDD to store canon .mov files via eSATA (usb/eSATA port).

If everything else fails, you could make copies of your video clips with halved resolution (or even less), and when done, render with the original files in full detail. It's a bit more laborous as it requires some amount of preparation (and you might want to first experiment to ensure that this works in your editing program), but as a last resort...

To some extent it is your laptop. You really need a good computer when adding multiple effects/color adjustments. I edit on a amd quadcore 2.8 with 16gb of ram and a 1gb nvidia card. It works pretty well but if I stack enouhg effects even it bogs down.

It doesn't matter how much ram your computer has, Vegas is a 32-bit app, so there is a bit over 3gb limit to the ram it uses, though in practice it uses 2gb at most. Even so, it should be possible to edit HD footage even old computers, if you transcode the video to an uncompressed format first.

The H.264 codec is meant for playback and not editing, and actually eats up a lot more processing power to decode than is necessary. That's why programs such as Cineform's Neoscene exist, as they can convert video to a proper, editable format, Final Cut and Media Composer have their own uncompressed formats in the form of ProRes and DNxHD.

I just want to clarify:

Nobody messes w/ uncompress data, so it's not the right term to use. All formats are in a compression but it's how much it compresses.

i.e. h.264 is highly compressed, prores (or DNxHD, Neoscene Codec) is intermediately(medium) compressed, RAW is slightly (lossless) compressed. Similarly to photo format: jpeg, TIFF/DNG, and RAW, respectively.

Again, "uncompressed format" shouldn't even be anybody's vocabulary unless you're messing w/ recorders.

You're right, but considering that about 0.1% of people would have any use for true uncompressed data or even have any way of capturing it, an intermediate codec is about as uncompressed as most people would ever think to go anyway. So yeah, not the right term, but no one would likely get the wrong idea either.

Make sure to render the clip before viewing if you have any effects on them.. The playback could also be choppy because your computer is slow.

Is the video quality still pretty well?
I'm a bit of a n00b as well when it comes to rendering and exporting and whatnot.

Would you happen to know of any examples? (I noticed in that video that on the screen the video looked a little blocky and odd) :P
