thanks for the heads up.

you are talking about one of the cheap card readers?

When I got my Scandisk Ultra II cards they came with a free USB to SDHC adapter and that works really well.

Well transfering from the EX via USB toclip browser for Sony Vegas PC is slower than realtime, 43mins of footage ended up taking 1hr 40mins.

If I buy a card reader this still has to use USB.
What are my options to quicken this up?

Are you sure your USB port is USB 2? It should be faster than that. I would give a card reader a try, they don't cost much and bypass the bottleneck that slows down SD cards in the EX.

Thanks,
Yeah, all USB ports are USB 2.
Any brands of card readers that you might suggest Alister?

Vegas 8.0 cannot read the mp4 wrapper. You have to use the Clipbrowser to rewrap into MXF. It does take a long time.
Be aware also that Vegas cannot join the files. You must use the Clipbrowser to do this, if you don't you'll get a glitch at the join.

ok, now I am really confused. I did on continuous file (7 minutes worth) it took 44 seconds to transfer. sweet. then I tried multiple clips totaling 7 minutes, and I am back to the slower than real time transfer. the copy check is not on, clip browser is set to processing speed over data protection.

is anyone with a PC, vegas, who is using clip browser to transfer the files, not BPAV's seeing faster times?

should I be looking into the sony SxS card reader?

I use my EX1 with Vegas 8.
I'm not certain exactly what you're doing when you say "transfer the files"?
If you're rewrapping to MXF then I'm not surprised at your outcome as the Clipbrowser is probably doing more than just reading one data file so the USB data rate would really slow things down.

I always copy the entire card(s) and it's structure to a folder on my HDDs. Then I use the clipbrowser to do the rewrap to MXF. The rewrap to MXF is slow, around 25% RT. The old version of the Clipbrowser was much faster.

yeah, thats what I am doing, I plug in the camera, open clip browser, select the clips, and select "export mxf".

for some reason I wasnt understanding that, I get it now, once the files are on the computer, its faster to rewrap than doing it while pulling them off the camera huh?

what I dont get is how to rewrap, once the BPAV file is on the computer, I cant find it in clip browser, and it wont let me drag it in either. sorry for being so dense on this, I have been going in 8 different directions trying to figure it out, I am frazzled.

Ian Planchon · January 9th, 2009, 06:26 PM

wait! I got it! hahaha, for some reason clip browser didnt find them the first time, but I got it sorted. 7 min file in 5 minutes. thats better than 15.

Im happy again!

curious if that sony SxS card reader allows faster transfer speeds straight from the card to MXF via clip browser.

thanks for all the help everyone.

Sorry I have been away for a few days and unable to responed.

What's the solution then with giving a client footage shot on these cards.
I'm also searching for a cheap card reader to do the transfer but as it's still going in via USB the transfer times will be large?

Regards

Ian Planchon · January 11th, 2009, 10:52 PM

you should be able to transfer the BPAV file to the computer, then open clipbrowser, locate the clips, and convert them to MXF. that solved the slow transfer time for me.

Simon Denny · January 11th, 2009, 11:36 PM

Thanks Ian,
Yeah that's what I have done. The BPAV transfer from camera to PC took a little less than 43 mins and then the MXF transfer was very quick but still this a slow work around if the client wants this after the shoot as it means 1hr footage will take around and hour to download to their PC.

Cheers
