Converting HD recording to MKV

Having raved about AVS Video Converter in my Converting your PVR recordings to DVD post, I was disappointed that my HD recording conversion did not produce any sound. Fortunately, this is a great video conversion product that it has its own support forum, and a quick post on there resulted in a patch that worked brilliantly.

I would highly recommend AVS Video Converter to you if you want to convert your SD and HD recordings to compress media formats to archive your recordings and save diskspace.

Convert HD recordings to MKV keeping 5.1 surround audio
To do this choose the following:

  • Start AVS Video Converter
  • Loading in your HD recording
  • Choose MKV in the Formats tab
  • Expand the options by clicking the Advanced >> button
  • Click on the Conversion Options tab

You should see something like the screengrab below:

AVS VC did not recognise AAC audio

Notice that your version of AVS Video Converter does not recognise the audio codec of the HD recording, as the details are blank. What you need to do is to download this AVS-VC_TS_AAC_patch.exe from the AV Programs download page off this blog, and install it, after closing AVS Video Converter.

Once the AAC patched has been install, restarting Video Converter and loading in the HD recording will result in it recognising two ‘unknown’ audio streams. It is not too important that it does not recognise that these are AAC audio because it will convert this to AC3 5.1 audio just fine.

UPDATE: Version 8.1 of AVS Video Converter now can process AAC audio. Download the update from the AVS4YOU website, now!

AVS VC patched

On the right of the Conversion pane, you will be given the option of what video and audio setting to convert you recording to. What we choose here is:

For video:

  • Video Codec: H.264/AVC
  • Frame Size: 0 x 0 Original
  • Bitrate: 4480

For audio:

  • Audio Codec: MPEG-2/4 Audio
  • Channels: 3/2+LFE 5.1 Surround

Leave the Input File audio stream on 1. Unknown name as the second stream is the Audio Description channel. Now click on Convert!

Convert Kung Fu Panda

AVS VC claims to be able to convert 3.4GB recording of Kung Fu Panda from BBC One HD in 2 hours or so. Time to make a cuppa tea! With the above settings it took 2 hours 20 mins to convert the 3.5GB to produce a 2.4GB mkv file – a reduction of 1GB.

Unfortunately, the output video does not playback properly on the HDR because this containter is not fully supported. It plays just fine in VLC media player however, so it is a valid video format in a MKV container. I am also unable to document this behaviour in the wiki as MediaInfo reports nothing about this video file accept that it is a MKV!

UPDATE: Version 8.1 of AVS Video Converter can now produce the valid MKV container. The HDR can now playback the MKV videos produced as well.

I also had contact with a user who says that by installing the patch his ReMaker program (another tool from AVS) broke, and AVS Video Converter kept crashing giving access violations, so becareful and think whether you need to install this patch or not.

UPDATE: Donot download the patch. Download the new version 8.1 of AVS Video Converter from the Online Media Technologies Ltd.

    Does this convert protected files? I thought all BBC One HD files were automatically protected?
    I can’t use this tool since I use Macs and Linux boxes, but if I know it’s possible I may investigate further.

    Protected recordings are encrypted. Like all video processing software AVS VC will not process encrypted recordings.

    There’s now a new version of AVS Video Converter – v8.1. This now can handle and convert HD recordings to MKV and will also playback on the HDR once converted. I will post another article on this soon.

    I’ve just tried this on a short HD recording from my HDR Fox-t2. Just used the default settings to convert to .avi
    Unfortunately the audio was badly out of synch and the video was not very good quality. I will persevere but looks as if it is not quite as straightforward as you suggest.

    I have not tested HD recordings to AVI, although this should work. Have you downloaded and installed the latest 8.1 version?

    I suggest recording in SD if you want to convert to AVI: https://myhumax.org/blog/?p=619

    I have tried most file conversion software and by far and away the best one, and its Freeware, is Format Factory, and it converts audio and video in sync at the same time. It will also let you perform a multitude of editing actions, like cutting joining remove or add borders etc etc. Hope this is usefull to you all.

    Hi – I am a new owner of the Humax Freesat HDR (1TB) and wanted to know if the above solution applies to this box as well as the Freeview version?

    I want to create a group of popular movies for my kinds and put them onto a NAS so that they can stream them when required.

    Unfortunately all HD recordings on the Freesat HDR are encrypted, so no is the answer.
