Huffyuv

[grindlestone]

Hi,

I'm trying to capture some old VHS stuff. I wanted to use Huffyuv to make the cap sizes smaller. However, I'm finding that I'm getting the exact same files sizes as I do with no compression enabled at all. For instance, 1 min at 720 x 576 x 25frames is giving me around 1.2g whether I use Huffyuv or not. I suppose I'm doing something wrong? Or is this the best I can expect?

I've tried virtualdub, virtual vcr, and Media studio video capture. I've installed the codec as per directions. I'm on win2k and have a modern fast system. Capture device is a Radeon 9600 pro vivo. I have viewed the capture guides here at doom9 closely.

HuffYUV compression is typically in the range of 2:1 - 3:1. That's with Predicted Median.

You're not the first to have this particular complaint, Rikkins does in http://forum.doom9.org/showthread.php?s=&threadid=88818. Note that Predicted Left will result in much bigger files than Predicted Median.

You may want to double-check your captures to make sure they're in HuffYUV and in YUY2, per the procedures I outlined to Rikkins in that thread.

Thanks for your post. I had seen the thread you mentioned but it didn't seem to adress my particular problem. I've since tried the Morgan mjpeg codec which I have had some good results with. I'll press on with this and see how I go.

Thanks again.

I had the same problem until I updated my VirtualDubMod to a newer build (from 2366 to 2439 - bugfix section) and used the huffyuv.dll from the listed site below. I do not know which one fixed it but it did work afterwards. You may look at those two things.

Thanks for this,

I'll give it another go with these new files.

Thanks.
