combining single-video .mp4 files
I am a member of a lab that uses multiple computers, some more powerful than others. On the less powerful computers (eMacs with 1.25 GHz PowerPC G4 processors), .eaf files using more that one video file (namely three .mp4 video files) are choppy, making annotation difficult. Since this choppiness does not occur on the more powerful computers, nor does the problem present in one-video .eaf files on these eMacs, it has occurred to us to create individual .eaf files for each of the .mp4 files so that this work can be done on any of the computers, and later combine these individual files into composite .eaf files with three videos (one primary and two secondary) containing the audio for the primary file and all of the annotation tiers from the individual .eaf files.
Is this possible? If so, I haven't been able to do so yet. Any help is much appreciated
Thank you,
Frederica
Re: combining single-video .mp4 files
This is possible. One can merge two transcriptions through File -> Merge Transcriptions... If you have three files you'll have to merge twice. The resulting file will only have the video file (and audio) of the first transcription document. The other two .mp4 video files can then be added and ordered via Edit -> Linked Files... (the Linked Media Files tab).
In case you have the same tier names in the individual files there is an option in the merging process, to determine whether or not annotations in the first source file may be overwritten by annotations in the second file.
