Incomplete AVI files

  • Updated 2 months ago
I am working in a big project with multiple complex video files. Every file consists of screen recordings, images, animations, callouts, videos, etc.

All videos are Full HD (1920 x 1080). And I need to export as uncompressed AVI in order to get high quality videos in WMV format. I don't export them in WMV format from camtasia because it gives little configuration options and flexibility and I need more control (bitrate or quality), so I export in full uncompressed AVI and transcode with Adobe Media Encoder.

The problem is that every AVI file exported by camtasia is not fully recognized by adobe. When I transcode them, all of them cuts before the end, some cut just a few seconds, others more than 90% of the file.

If I put one of those avi into Adobe premiere, only the part that Encoder has encoded shows: the same part encoded is what premiere shows.

As a workaround, I have managed this in two steps: Selecting in camtasia from the begining of the clip to the middle, exporting the selection to avi, selecting the second half, exporting to avi, put those avi's into premiere and transcoding to WMV, but this is a weird way and very time consuming way of doing.

How can I export from camtasia in a loseless format and then transcode from premiere or media enconder in a more direct way?

I’m not sure what your definition of an uncompressed AVI video is. I know that a lot of people misinterpret what uncompressed represents.

Fully uncompressed AVI files are monumental in size. They can reach 1 or 2 GB per minute for a 1920 by 1080 video. Exporting video content of that size will get you nowhere. TechSmith’s AVI codec “TechSmith Screen Codec 2”. Creates an AVI that is of a high enough quality to be re-rendered.

I don’t have any problem producing videos using TechSmith Screen Codec 2 using Premier Pro. I usually don’t my videos through Media Encoder because it’s an extra step that isn’t necessary. My point is that the codec is recognized by Premier Pro, so there’s no reason Media Encoder wouldn’t do the same.

Thanks for the answer. My definition of uncompressed AVI is the Camtasia definition: in the settings of AVI production there is an option called 'uncompressed'. I know the videos has huge size, but first, for the duration of every video I produce and with the size of my hard disk I don't have problems with that. Anyway, I have tried with all AVI options Camtasia gives: Techsmith AVI Codec, Microsoft Video 1, Intel YUV... no chance. With all of them I get the same results: if an AVI file of, lets say, 20 munutes duration only shows the firts, lets say, 2 first minutes in premiere, shows those two minutes with every codec I use. And each video has its own 'first' durations. Some of them just cut the last 30 seconds, other cuts the last 15 minutes.. it appears to be random, but when a video has the cut in one time point, the cut is always at that time point regardless the codec I use when export to AVI.
