What happened to Screencast quality?

Video screen size for wmv files is microscopic. Is there a way to fix this? This seems to be a recent change, it used to be ok. Also, when the last overhaul of Screencast was made, the audio seems to be degraded in wmv files. This is a big issue for classical music videos. I tried using MP4 format, but it takes forever to start the video rolling when a visitor to my site wants to view it. It is not an issue of internet speed. When I use bitsontherun for a backend solution, MP4 files load fast.

Hello Phyllis I have a couple ideas for you.

1. WMV quality. We never mess or re-encode content in any way. One thing you could try is holding Shift and click the refresh button in your browser. That will clear the cache. It's a long shot, and if it doesn't work, I'd recommend following up with support. http://support.techsmith.com.

2. I know what you mean about the MP4s having to load. Why that is happening is because the way they are being produced is not optimized for streaming. What software are you using? See if there is an option for streaming. The technical reason it's not streaming is because something called a MOOV atom is at the end of the video instead of at the beginning.

In regards to Mike's response to question #2 and the MOOV atom:

If a MP4 is not optimized for streaming, it can be fixed quite easily using a free tool called QTIndexSwapper. The only downside is that you would need to upload the MP4 again to Screencast.

Here's the article we have on this, which includes a link to download QTIndexSwapper:


Once you install QTIndexSwapper, you'll just need to browse for the file and click the Process button. If the MP4 was not optimized for streaming previously, it will generate a new MP4 file that is.

Hope this helps!

If you use QuickTime to create the mp4/h.264 file, you can enable Fast Streaming to allow the video to play right away.

Thanks, I will look into your solutions. I am using PowerDirector 4 for editing footage prior to upload.

Prolonged playtime.
Dear Techsmith,
Im just starting out on the net & am very grateful for the free use of your video service.
Unfortunately when I hit the 'play' button on my video(hosted by yourselves) on my blog it always takes around a minute of 'blackness' before it begins to play.
Im clearly doing something wrong.
