Large Dxtory Files
« on: September 30, 2013, 06:37:16 am »
I downloaded Dxtory today and started to record League of Legends. The recording stopped mid-game and I couldn't record anything else. It was about 15 minutes of gameplay and then I realized the file was 117 GB. Does anyone have a fix to this? Is it supposed to be like this? Thanks.

It is normal if Dxtory Video Codec was used.

capturing lossless, RAW/not-compressed video results in HUGE files, no way around that.

simple math shows this
Code: [Select]
recording_size = resolution_x * resolution_y * display_bit_depth / 8 * recording_fps * recording_length
so, 15 minutes (== 900 seconds) of 30fps 1920x1080 32bit (though 24bit image is saved, this is normal and doesn't affect the image quality):
Code: [Select]
1920 * 1080 * 24/8 * 30fps * 900s = 167 961 600 000 byteswhich is ~156GB

You might want to look into YUV422 and/or other codecs, like Lagarith (lossless, but compresses quite well, might have some performance impact) or Ut Video Codec (less compression than lagarith, but somewhat less performance impact).
Lossy codecs can get you even smaller files, but generally I wouldn't recommend those.
