Troubleshooting poor quality video problem & need some perspective
Nov 05, 2012
I recently supplied a talking head video vignette running 0:57 secs to a developer that is writing a portion of a training course for our company. I was asked to provide the delivery output in FLV.
Brief summary of the work flow: The sequence was edited in Final Cut Pro 7. Upon approval of the edited clip, I exported the sequence as a Quicktime file using the sequence settings run as the default (ProRes422 LT; 1920X1080; 30p; 48kHz 16-bit audio). Then I took the .mov export into iSkysoft video converter and chose the FLV with H.264 codec; 1280x720@30fps; kept the bit rate down to a 6.8 MB size (was told it had to be under 10 MB to run correctly) with MP3 audio codec. I then reviewed the FLV file using Adobe Media Player to be sure all looked okay.
I delivered the file to him last Friday (along with a backup version of the original .mov delivery and a .wmv for good measure). This morning he sent the link to a beta version of the module. My formerly sharp and bright footage is completely fuzzy, pixelated, looks underexposed and terrible. What the heck did I do wrong? I read somewhere in these forums that H.264 is better to use than the FLV video codec so I don't think that is the problem... ideas anybody?

Welcome to E-Learning Heroes Ell!
Have you read the tutorial on converting to FLV? You can find it here. Down at the bottom of the tutorial, there's a lot of information regarding quality and what you can do to try to improve it. You may want to check the bit rates for your current video, as well as the other tips mentioned and see if that helps.
Let us know if this helps!
Hi Christine, and thanks for the welcome. I didn't use the Articulate Encoder to do the conversion from the .mov to FLV as I don't have Articulate at my disposal. The editor used was FCP7 and the conversions were done using iSkysoft which I have had very good results with. I was asked to supply an FLV video that he could simply ready to drop into place without having to convert... would it be better for that person to take the .wmv file that I also gave him when I supplied the FLV, and run it through Encoder again? Mind you that would be two levels of compression then... that wouldn't pull the quality down even more?
Hi Ell,
Thanks for getting back to me! I've spoken with a few of my colleagues on our tech team and the best suggestion is to try converting the file to MP4. This is the preferred video format for Studio '09 and it should produce the best results. You can try to convert the original file yourself, using Articulate Video Encoder, or the person you're communicating with can try using it.
I noticed you said you don't have access to the Encoder yourself. If you'd like, you can use the 30 day free trial to convert the video and see if it improves the quality. You can get the free trial here.
Thanks!
MP4 it is, will try it. iSkysoft will allow me to convert to that format, so will press on and see what happens.
Thanks for this information and the link too!
you may also can follow this useful guide a bout flv files to mp4 format. please keep in mind that some presets can optimized the process, so you dont need to set the output parameters.
