Fault Tolerant Recordings

Some video formats hold some important information in memory until the recording is complete.
This means in the event of a power outage or system failure these recordings may be corrupt and difficult to recover.

TIP: Use the "New File Every" option to create new recordings at regular intervals so if one file is lost in event of a power outage, the majority of the recording can be recovered.

The following table describes the fault tolerance of each recording format supported by vMix:

Type	File Format	Fault Tolerant?
vMix AVI	AVI	Yes
AVI	AVI	No
AVI	MKV	Yes
MPEG-2	MPG	Yes
MPEG-2	TS	Yes
MP4	MP4	No
MP4	MP4 (with Fault Tolerant checkbox ticked)	Yes (Important Note: Fault tolerant MP4 recordings do not work in all devices and software and should be thoroughly tested for compatibility prior to use in any productions.)
WMV	WMV	Yes
FFMPEG	MXF	Yes
FFMPEG	MOV	Yes
FFMPEG	MP4	Yes
FFMPEG	MOV (Indexed)	No
FFMPEG	MP4 (Indexed)	No

vMix AVI is the best fault tolerant format out of the above.
