64-bit Vegas and AVCHD Lite

Hey Gang,

So I'm having some trouble with Vegas 64-bit and AVCHD Lite. Playback in other media players is excellent, but playback in Vegas 64 is frought with random color / brightness flashes and compression artifacts. I'm not talking about stuttering... speed is fine and plays at full FPS. I'm talking about messy video. Worse, I can't seem to render to any other format (at least I've tried MC AVC, Sony AVC, and MPEG2,) without the "corruption" showing up there too. It's not consistent frame-for-frame... in other words, if I play the clip on the timeline once, frames 31,33,35,37,39 might flash, for example. But the next time it might be frames 44,46,48,50.

Vegas 32-bit seems to work fine! I've confirmed this on two different systems. 64-bit = problems, 32-bit = good.

Try it yourself! A sample clip is available here (scroll down:)

Anyone else seeing this and found a way to fix it?

if it's good in 32, why not transcode to mxf to work in 64?

frankly i think this is one of the root problems with vegas, or rather people using vegas. they expect it to work with every variety of avchd on the market, let alone tl - (not just your problem scissorf.).

it's been mentioned before i know, but using 3rd party softwarte (perhaps that supplied with the camera) to transcode to a 'formal' format might be the go?

btw. i see the problem in 64 / but none in 32 and xfered to mxf is fin in 64....

just want to chime in and say that a friend of mine has been having the *exact* same problem as described in the topic start. also using Vegas 64 bit under Win7 64 bit and also with AVCHD-Lite (from a Panasonic Lumix camera).

i did a search on this board before but could not find a single post about it, so i thought i must be nuts. but now at least there is confirmation that it's not just me...

i don't agree with "ushere"'s post, who makes it sound as if we expect too much. AVCHD-Lite works flawlessly with Vegas 32 bit and windows XP, so it's not strange to expect this to work under 64 bit as well.

haven't tried transcoding yet, but imho it should not be neccesary. i'd rather just use the 32 bit version, but then there is this 2 GB RAM limitation. we got a system with 12 GB of RAM especially for video editing...

32 bit version works very well with Pana AVCHD lite stuff.

Forget V9c 64 bit. It simply do not works with theses files.

AVCHD Lite IS a formal format, developed by one of the two companies who developed AVCHD (Sony and Panasonic.) Given that Sony was an initial developer of AVCHD, you'd think they'd want to support that sub-format. And they do, in Vegas 32 bit. I'm simply pointing out what may be a 64-bit bug.

Proper support for AVCHD and AVCHD Lite is only going to become more essential as the proliferation of cheap digicams spreads these formats. And yes, I DO expect my $550 "professional" editing software to be able to play the same modern formats that readily-available free software can, and not only just as well, but better!

There is NO FIX just a kludgey work around.

Unfortunately its NOT just you. Just do a search on this board and enter "red frame".

I agree if it works in 32 bit, it should work even better in 64 bit! (;

Another work around that may work for you is to batch convert your files using Proxy Stream:

I'm really hoping that 9d (hopefully to be release this month) will have a lot of these bugs ironed out.

I agree! I use 1080p 60fps AVCH video and it's disappinting that a $75 consumer grade video program like Video Studio X3 can play and edit these AVCHD in auto proxy mode flawlessly and a $500 "Pro" grade software cannot.
