Hi i have just uploaded 3 mp4 files 17-35mb one seems to play back fine the others seem to be have corrupted in the transcode...lost sound images and pixalted..
Is this a known problem..
Thanks Dale
Yes, we are aware of some quality issues that have crept into our transcoding service. We are working on the problem.
Thanks,
Is there a maximum file size for uploading files?
We currently cap the size of video uploads at 200 MB.

Ah, bother - I've a pile of backgrounds here, of which 15% top out at 207-229!
Can I ask: what format/bitrate are you transcoding to - may as well output things we create in the right format if possible.
Thanks

I have been converting my videos to 480x640 MP4s. Because of the nature of most projectors, this smaller video will still look pretty sharp. Won't look great on a computer monitor, but projectors will be fine. Plus, MP4s are highly compressed, versus AVIs and WMVs that most backgrounds come as. I have found that this has made my 200MB videos around 40MBs.

On Mac videos are transcoded into .mp4 format. In Windows videos are transcoded into .wmv format.
Really? WMVs are awful, even on our PC. Our Windows machine doesn't have a single WMV on it. Everything we do on that PC is mp4. Smaller files, faster playback, less crashing. Seems odd that the MP4s we upload from our PC are getting transcoded to WMV, when it will play MP4 just fine.
Sadly, the set of available video codecs differs from machine to machine. We would like to send mp4's to PC's as well and cut our transcoding/storage expenses in half, not to mention program complexity. Transcoding is the price we pay in pursuit of a presentation that is platform-agnostic. In the end, wmv was the only format we found consistently supported across all target Windows machines.

Is it an issue that we are using multiple platforms (Mac and PC)? Our videos are not transcoding correctly. We create on a Mac and deliver the video through a PC and projector.
No, it sounds like you're doing things correctly: being able to develop a presentation on a variety of machines is one of the particular features of Proclaim. Transcoding quality remains an issue to be resolved, however.
The work-around in the meantime is to host the files locally on your presenting computer and refer to them there from the presentation slides.
Video transcoding issues should be resolved. Please try re-uploading and let us know if you still see artifacts.
