FS700 maximum file time / size

Hi there,

Recently I have had 2 instances where a take was chopped off into two different files on the SD card. I think both were cut at around the 10 minute mark or so. These would've been alright if I didn't lose like half a second of audio at the cut (the video was smooth at the cut - didn't lose a frame).

Do you guys know if there is like a maximum file length or size that the FS700 writes onto the SD card? Or maybe it was bad luck on my part or some other malfunction?

Thanks
 
Hi,

Yes i've had this issue as well = i cal it an issue as i find it quite annoying! There are ways to get around it though. I think what you have are 'spanned' clips. something to do with fat32 or something limiting a file size to around 2.13Gb which turns out to be around 12 minutes on the FS700 in AVCHD.

Depending on what you cut with you can do a few things to fix...

Adobe Premiere pro - just import both spanned clips into premiere and the program will sort it out for you with no glitch in audio or video (at leased with me it does)

When i cut in Final cut 7 i transcode the avchd files using clipwrap - make a note on which files are spanned - you can usually see this by the size of the files, the ones that are 2.13Gb are usually spanned unless it a coincidence. When you import the files into clipwrap, select the spanned files and go to the 'clip' menu at the top and click 'join selcted clips'.

When clipwrap transcodes the footage the resulting pro-res (or whatever) will have the spanned clips joined into one file, then when you import into FCP7 you wont have any glitches in audio or video.

Finally i put the files into Bridge and change their names to something you will recognise so that way you won't have 50 '00001.mts' files on your system! I learnt that this is needed the hard way!!

Anyways, if spanned clips are you issue then this should help!

This is a well-known issue. Yes, any clip over 2GB will be split, and re-joining them isn't totally simple. The crucial thing is that you must NOT import the ".mts" files from the card -- these by themselves are not the whole picture. You need the other meta-data in the AVCHD folder too, in order to re-join split clips correctly. Copy the entire "PRIVATE" folder from the SD card into your project, then rename it to something sensible ("July 1 indoors", something memorable).

In Premiere CS6, you can open up the "AVCHD" sub-folder in the footage folder, making sure that "View As: AVCHD" is set. Then import the clips you want. Long clips that got split will be correctly re-joined, with no audio glitches.

In older Premiere versions, import the whole "PRIVATE" folder into your project.
