But I do suggest that you look to the Hauppauge driver or configuration. I'm using a 100 minute recording which has a total size of 6.35 GB (6,827,624,397 bytes) as my sample. My calculated Bitrate is closer to 8,448 Kbps based on file sizes. MC reports the Bitrate for the recording as 15,192 Kbps, which has to be compressed as the simple calculated data rate for video of 8bit 1440x1080i 25fps: 8x1440x1080x25/2 = 155,520,000 bps = 151,875 Kbps. Wikipedia has a page listing the Storage and Data Rates for Uncompressed Video, where you will see that 70GB/hour isn't a very high quality video.Īs an example of the MediaInfo output I get on DVB-T recordings in JTV format, see below.īTW, I've just realised that MediaInfo is only showing the Maximum Bitrate for my video below, which is a bit useless. Maybe there is some setting in the Hauppauge WinTV-HVR-955q driver, or configuration panel if it has one, that sets some special format or quality level, which is creating these files. As far as I know MC just records the raw transmission in JTV format as well though, so it is a bit of a mystery. The files are playable aren't they? Thinking about it, you must be recording the raw Transmission Stream, without any compression or processing on the card. Or perhaps if Yaobing can find time to assist, you could send him a sample video file.
Maybe you need to find a video tool that can identify what the format actually is. If those files are playable, I guess it means that the file isn't a known media format, or there is no header data about the format at all, or something like that. When MediaInfo only shows the file name and size, that usually means that the file isn't a media file. I am not getting any stuttering in audio or video at least. I have tried with both Hardware Accelerate video decoding and VideoClock both enabled and disabled. Tools > Options > Video = Red October Standard

Configured Television settings for the capture device and EPG/channel guide. To test: I uninstalled MC21 and cleared settings. Checked again at 24 minutes and I am now at about 28GB of disk space used in my Timeshift file location.Ĭapture Device: Hauppauge WinTV-HVR-955q (1114xx ATSC/QAM) USB device configured for Analog cable. Even now, I am less than 10 minutes time shifted on an analog channel and over 10GB have been consumed in the timeshift folder. I recorded a 3 hour football game and 210GB were consumed by the MC21 files. While timeshifting or recording shows, my recordings take up about 70GB on disk per hour.
Is this normal? Hauppauge's site seems to indicate that my recorded files shouldn't be this large.
