TriCaster Hardware Storage

DV codec versus NewTek 25 codec

Q: Does TriCaster ever create ‘native’ DV clips? When is the NewTek 25 codec used to record?

A: When rendering from the TriCaster Editor using the Prepare for VCR button, or when captured from the Capture Tab, TriCaster creates native DV AVI files, whereas NewTek 25 codec is used to capture a live production.

Why does my hard drive say it is full but all my files only take up a fraction of the total space?

Hidden files and folders will take up space that is not accounted for in some circumstances. These hidden files and folders are temporary and cache files that help TriCaster's performance, while you are currently using some of these for a production a lot of them may be old and unnecessary.

Warning: Do NOT do this for the C: drive, removing the same files from the C: drive will result in problems that can only be resolved by restoring the TriCaster to it's original state. Also, if you have any custom or third party DVEs stored on the D: drive make sure not to delete anything inside their respective directories

To delete these files go to Admin mode and open up My Computer > D: Drive

Now go to Tools > Folder Options > View, without having to scroll down you should see the option Hidden Files and Folders, make sure this is set to Show Hidden Files and Folders. Now click OK to apply the changes and close Folder Options.

In the D: drive press Ctrl + F for find, for all or part of the file name type in NewTek Info (with the space in between, searching is not case sensitive by default). Under More Advanced Options make sure the first three options are checked (Search system folders, Search hidden files and folders, Search subfolders) and click Search.

After the search is finished numerous files and folders should have been found. You can right click in the results and choose to Arrange Icons By > Type to group the folders together as that's all we need to delete.

If you get a prompt that a file or folder is too large for the Recycle Bin choose to permanently delete it. Afterwards right click on the Recycle Bin and choose Empty Trash. You should now have a lot more space available.

Upon relaunching TriCaster you may find that a playlist or project takes longer to load. This is because new temporary files need to be created. Once these are created performance should increase and maybe even be better than it previously was.

Deleting NewTek Info folders should only be done when you're running out of room, and isn't anything you need to do regularly.

Remember, NewTek Info folder will recreate themselves but will appear as much smaller file sizes than the ones we just deleted and are necessary for performance.

Can TriCaster record to or playback from external USB and FireWire-based drives?

It is recommended to always record to and play back from the TriCasters internal D: drive partition whenever you can. However, it is usually safe to record or play back video from an external drive.

Here is some more information on using external drives with a TriCaster:

Differences between USB and FireWire drives

USB has slightly faster transfer rates but FireWire is preferred given its ability over USB to utilize Sustained Transfer Rate (STR). This technology allows for a constant transfer which is important for video. USB uses whats called Burst/Interface Transfer Rate which collects data in a buffer before sending it across the bus to the device to be written. This method is great for file transfer, but is too inconsistent to sustain video.

What kind of external drive to purchase

A lot of drives offer both USB and FireWire so you can get the most out of them. Some drives are also small and discrete, these use the 2.5" drive standard. While convenient and portable 3.5" drive should be used. The larger drives usually need to be plugged into an outlet but are faster and offer more space for less money.

What to know when you get an external drive

Most drives write data to the drive in a format known as FAT32. This archaic format limits file sizes to only 4GB per file. On TriCaster that can be equal to only a fraction of an hour worth of recording.

The required drive format NTFS

NTFS allows you to write files that can be as large as the drives available space if need be. This can equate to several hours of video in a single clip depending on the drive capacity.

Limitations of NTFS

NTFS drives can be read and written to by any Windows 2000/Vista/XP/7 based PC. Macintosh OSX computers can read NTFS drives and copy files from them but are incapable of writing to them.

How to change FAT32 to NTFS for video

Exit TriCaster to Admin Mode and then plug in your drive. Open My Computer and find the drive you plugged in; it will likely be the E: drive. Highlight the drive and go to File > Format, when the Format window comes up leave everything on default but make sure File system is set to NTFS.

Formatting will ERASE all data on the drive, so make sure anything you already have on there is backed up as it cannot be recovered.

Why doesn't TriCaster 300 record in DVCPRO HD?

While DVCPro HD would offer improved compatibility with Avid systems, NewTek avoids that format for recording because it is not full HD.

DVCPro HD uses 960x720 pixels for 720p and 1280x1080 for 1080i ... Whats more, rescaling causes degradation of quality even without compression. So scaling a 1920 image down to 1280 and back up to 1920 impairs image quality.
