hi folks,
At the paris dojo, we had a camera running - and we even got most of the sessions recorded. However, the camera outputs MXF and SIF files, which neither youtube nor vimeo will accept ( well, and at nearlyt 30 GB an hour, my 1mbps uplink from home isnt going to quite make it worthwhile uploading either ).
I dont know much about video, so could use a hand here : whats the best way to convert these into a usable format, without losing too much audio quality and getting them online ?
I have used Wondershare in the past for converting these two formats with good results... Was the second SWF versus SIF?
Hope this helps!
Bruce

that looks good, ideally I'd prefer to try a linux solution though.

My first though was "use handbrake" and a quick google shows this random guy on the 'net queued all his mxf files with handbrake and created some nice m4v files.

handbrake might be just the thing, am going to give it a shot now and if it builds cleanly on c6, then run one video set overnight to see how it turns out. thanks!

handbrake is in the nux-dextop repo.

Handbrake is just a GUI for ffmpeg. man ffmpeg ffmpeg -i oldfile.vif newfile.mp4

perfect! just worked, i had to add -strict -2, to have it work with the aac codec; just need to stitch them together and get them uploaded now. I'll do one example session first, see if that meets the quality spec we need and then do the rest.
thanks
Here we have Colin Charles doing his MariaDB Deep dive on CentOS-7, at the Paris Dojo : https://www.youtube.com/watch?v=agWyf-huHps
on my 2.5mbps adsl2+ link ( yes, its 2.5, no typos ); the quality of the youtube video is distinctly poorer compared with the local mp4 file I uploaded..

Here's what youtube-dl says is offered by youtube for that particular video:

My guess is that you are playing it in your browser without mp4 support so you get the webm which is lower quality.
I prefer free formats myself so I just get the webm one myself. I think the quality of it is fine.
If you want the higher quality video, you need a browser that advertises the ability to play mp4. For more info so:
