Nanoflash and XL-H1 at DVinfo.net

Hi,

Is there any Way to record SD to Tape and HD out of the camera on to the Nanoflash seperately.

Just asking because HDV sometimes takes 4 to 5 seconds to start recording after i press the record button and SD to tape just records right away. Which has probably to do with long Gop vs. Intraframe.

At the moment i am using Prerecord on Nanoflash but it would be cooler if the Recording to Tape would just Start right away. To get less shots of the Floor. :)

Any suggestions?

cheers..

Philipp, I´m a bit confused about what you asking about?

There is no difference how long it takes to start to record to tape on the XL-H1! Both SD and HDV will record instantly to the tape, if the tape is in pause-mode when you hit the record-button.
If the tape however has been put to stop (which happen if the tape has been in pause-mode for too long). There will take some additional time eg. 2-3 seconds for the tape transport and the record head to align on the tape and start to record.

I think Philipp means there is a lag before the Nanoflash starts to record.

Hi Philipp:
I have an XL H1, which I use with the Flash XDR, and I simul shoot HDV tape as I'm recording to CF cards. Part of the lag in time from tape to Nano actually rolling comes from the fact that the HDV tape record must be rolling, or else the XL H1 will *NOT output the TC signal, which is what's firing off your Nano Flash into record. If you turn off *Pre-record, then you might get about a second faster roll on the Nano record after HDV tape roll. You cannot shoot SD to cassette and HD to Nano at the same time with the XL H1.

Thank you for the answers..

Well.. In HDV Mode..Sometimes when i hit the record Button it starts right away with recording. Other Times it takes Ages to start Recording. During this 4 to 5 seconds the Record Symbol blinks like its going from Stop Mode to Record.

So yes. The camera definitely has to get the Tape ready. But its definitely not going from Stop Mode. And also it takes longer.
In SD Mode it always starts right away to Record. I believe in HDV its a long gop thing and it needs to realign the Tape more exact. Just a theory. I own an old Xl-H1. One of the first, actually.

I will stick with Prebuffer on the Nano. Just wantet to avoid unnecessary Footage.

cheers..

Dear Phillip,

This may be obvious:

The XLH1 keeps the tape head spinning for a while after each recording stops.

If the tape head drum is not rotating, it takes a few seconds to spin up, thus delaying the start of the actual recording.

ok..thank you
But it is also happening if there are only a few seconds between two shots...

I did a test and timed the delay.. I got one delay between pressing the record button and the actual recording which was 7 seconds long. And 7 seconds feels like Ages when your doing Documentary stuff.
Average is about 3 seconds..
70 percent of the Time it starts right away..

Do you think this is normal? I mean its not so bad as i have prebuffer on the Nanoflash, which works pretty well.....
