Dear Amanda,
I have had problems with these file formats before and have converted
the files for use in ELAN with Adobe Premier (The user manual will tell
you which ones are acceptable. mp4 works well). I must admit that I
still work with an older version of ELAN so I do not know whether the
file formats you mention should now work.
Note also the file format info at LAC (Language Archive Cologne) below.

Best regards,
Christina
Video Recommendations:
Video formats used in language research and archiving are in many ways
determined by the limitation of high-level consumer (“prosumer”) digital
cameras. Most modern cameras record video encoded as h.264 (sometimes
indicated as AVC or AVCHD in camera interfaces). Although propietary, we
consider this encoding currently the most suitable encoding for our
purposes because of its widespread support in software and hardware.
The most common audio encodings in video cameras are LPCM, AC3, and AAC.
From linguistic point of view, LPCM encoding (often indicated as PCM) is
highly preferable and should be chosen if possible. AAC is a lossy
compressed format and is not suitable for all kinds of analysis. It is
however the preferred option if no PCM audio can be provided. Audio
encoded as AC3 can cause issues in ELAN and Exmeralda on some platforms
and should be re-encoded as AAC before archiving.
The MP4 container specification does not allow LPCM encoded audio. If
your camera can record LPCM audio with h.264 video, _*we recommed to use
the MOV container format. MOV files can be problematic for video
annotation programs such as ELAN. *_
_*The best way to deal with this issue is to produce a working file with
AAC audio and h.264 video in a MP4 container and use this file with
ELAN*_. _*For archiving both the MOV and the MP4 file should be
submitted *_together with the ELAN file.
Having two files for one recording increases the storage requirements
for project work and archiving, but the advantage of archiving
uncompressed audion and video in one container compensates for the
disadvantages.
If your camera can only record compressed audio, we suggest that you
also record uncompressed audion with a dedicated audio recorder. In case
you have no dedicated audio recorde available and you can only record
compressed audio with your video camera, you might want to derive a WAV
file from a lossy compressed encoded AAC audio track of a video file,
this file – despite its appearance as uncompressed LPCM data – will not
be suitable to some types of analysis. You should indicate the source
format of this file in the metadata to inform future users of the
provenance of this data.
Purpose File format Video Encoding encoding options Video Resolution
Frame rate Audio Encoding Sampling Rate Bit Depth Bit rate
*Recording* — h.264 profile: main, level: 4.0 1080p 30fps LPCM 48
kHz 16 bit
*Archiving* MOV h.264 profile: main, level: 4.0 1080p 30fps LPCM
48 kHz 16 bit
MP4 h.264 profile: main, level: 4.0 1080p 30fps AAC (LC) 48 kHz
128-384 kbps
(WAV 48 kHz 16 bit)
*Working* MP4 h.264 profile: main, level: 4.0 1080p 30fps AAC (LC)
48 kHz
128 kbps
Note: While we recommend a 30fps frame rate, we discourage any change to
the frame rate after recording. Any common frame rate besides 30 fps –
such as 24 fps (e.g. used in NTSC), 25 fps (e.g. used in PAL), as well
as higher frame rates – are acceptable.
Video file formats recommended for film archives such as uncompressed
MXF or lossless JPEG2000 are not recommended for most digital video
recordings as these recordings were originally recorded in a lossy
format (mostly h.264 encoded). If you are intending to digitize and
archive non-digital film, please contact the LAC helpdesk
<mailto:lac-helpdesk at uni-koeln.de> for further arrangements.
