hi,

when capturing HD footage to edit in Vegas...

I'm seeing multiple glitches/artifacts in .mts source video captured in my greenscreen studio w/my sony hdr-sr11 handycam... any ideas on how to fix?

you can watch in this rough-cut video (me playing tenor sax):

this snow-like pattern flashes on occasional seconds...even had an audio dropout...the battery's fully charged, well-lit studio, it's driving me nuts... i need clean footage...my workaround is filming several takes of each shot, but that results in a choppy amatuerish video like that one...

I'd appreciate any tips, re how to not get glitches in mts-captured footage... thanks!

any ideas on what to test?

for example I got footage glitches saving to the cam internal hard drive; next time I'll save to memory card instead, in case that's it

hmm it may be actually after ingesting mts into AE, the ae render is introducing artifacts; need to double-check

Your camcorder is an AVCHD camcorder, so assume that by "capture" you mean that you imported your video from the camcorder to your computer using Vegas' Device Manager software.

That said, your green screen work actually looks pretty clean to me! Even through your fade-outs!

Can you indicate a point in this video where you're seeing your issues?

It's possible something is bugging up the green screen effect -- but it's hard to say without seeing your original footage.

Does this issue appear only on your finished video or is it also visible at the same points on your original raw footage?

thanks...here's a cap of what the raw greenscreen footage looks like:

Are you rendering using the GPU? It looks like the type of glitch that the GPU rendering would make.

hi Donald, thanks for the tip, yes using GPU-accelerated renders in AE + Vegas; have old nvidia drivers; maybe that's it

Ken, I'm not familiar with your camera, but have used other Sony handycams including the CX430V that I'm using now. I had a very similar problem last year that turned out to be read errors from the particular card reader I was using. I changed readers and the problem was solved--no more glitches. Moreover, rather than using MTS files directly from your camcorder, you may want to use Sony's Play Memories which will link together files greater than 2GB and also change to an m2ts suffix. Moreover, it changes the file name to the date code when recorded--a really nice feature. It does something else (?) in that the m2ts files play better in Vegas (smoother preview) than MTS files directly from the memory card. Whether this might apply to your camera, I have no idea, but thought I'd share.

hi wwaag, thanks for the tip; I appreciate it...I'm not familiar w/ play memories, will check it out. good feature re date-code title, agree... many thanks
