  • Updated 2 years ago
I have recorded 200gb "let's play" videos. i use lagarith lossless codec to recording. Everything did work fine until now. I can view those videos, but i can't import them to Camtasia Studio 8 or sony vegas 10 pro. it's says : "no decoder was available for the following codecs : LAGS. Gspot says that lagarith is istalled. I uninstalled all codec's using revounistaller, then i manually deleted all registry setting from those codec's. then i booted my computer. Now Gspot says i don't have lagarith installed, OK i install all codecs back, and it's says again lagarith is installed. Still doesn't import those files -_-, couple days ago everything was normal

Oh i forgot, i just cant convert them to anything without camtasia or vegas . The file size is over 100GB and it's contain 3 audio tracks: game sound,my sound,my friends. And i cant just mux/convert these because the audio balance can't be ok.

What are you using to make these recordings?

Can you post a smaller sample recording somewhere that exhibits the problem?

The large file size is likely due to the Lagarith lossless codec. If you're using Camtasia Recorder to make your recordings, we'd recommend leaving the default codec, which is Techsmith Screen Codec 2 (TSC2). This codec was designed for high performance + high quality, and should give you a significantly smaller file than a lossless codec would.

The problem may be the 3 audio tracks. We only support 2 audio tracks (microphone, system audio) in our CAMREC container. For other containers (AVI, WMV, MP4, MOV), we only support a single audio track. That's why I'm asking about the source of your recording. If we can get a small, short sample video, we may be able to give you more specific advice.

Thanks in advance for any additional info you can provide.

I installed the latest versions of Dxtory and Lagarith lossless codec, and recorded using a single audio track. The resulting AVI imported just fine into Camtasia Studio 8. Both audio and video played as expected.

Next, I recorded with 2 audio tracks. The resulting AVI imported fine into Camtasia Studio 8, but only audio 1 played. For now, this is by design. As I said above, we currently only support a single audio track for AVI files. Here's a screenshot of the AVI file properties in GSpot: http://screencast.com/t/ld5L0OXSk and in MediaInfo: http://screencast.com/t/hV4s8EtJJHa1

As a side note for this 2nd test, I took the AVI into GraphStudio and found that the audio 2 track cut out quite a bit, as if samples had been dropped during recording. This could be a limitation of the drive I was recording to, which only has a throughput of around 20MB/s according to the Dxtory speed test in the Folder tab. Here's a screenshot of the AVI in GraphStudio: http://screencast.com/t/BccTB2crp

Comparing the GSpot properties from your file to the one I created, I noticed this seemed odd from your screenshot: http://screencast.com/t/FRZKXRFfnH3
Perhaps the 107GB size of the AVI file is more than what GSpot can handle? Or perhaps the 107GB file was not written out correctly by Dxtory? I'm not sure. I'd suggest trying some shorter captures to see if those can be imported.

Also, if you intend to edit these in Camtasia Studio, I'd recommend PCM 44.1kHz, 16-bit, Stereo as the audio format. This is the format we use on the timeline. Using this as your capture format in Dxtory will avoid resampling when you put it on the Camtasia Studio timeline, which can cause a loss in audio quality.

Hope this helps.

1.) You must choose "Run as Administrator" when you install a codec. If you don't do this, your movie will never open in Sony Vegas.

2.) If you are using Window 64 bit, then you should install both 32 bit and 64 bit versions of the codec. This applies to Lagarith and x264 codecs.

3.) Always make sure that you have Sony Vegas installed before you install a new codec.

4.) The best codec is a 32 bit codec called "Packbit" and can be found at the DXtory website. It is light years ahead of Lagarith and x264 and it produces zero game lag when recording.

5.) You cannot open an avi movie recorded with the 32 bit Packbit codec in Sony Vegas 64 bit, but you can download and install "XVid MiniConvert" and use it to convert a movie recorded with Packbit - and the converted movie will then open in Sony Vegas 64 bit. Converting with XVid MiniConvert can be a slow process, but the smooth high quality is worth it.

6. Always record at 60 fps and render at 29.97 fps. Most people are unaware that recording at 60 fps produces less game lag than if they were to record at 30 fps. Also, YouTube converts movies to 29.97, which is why you should render your movie at 29.97 in Sony Vegas.

Most people like to use Lagarith to record movies. Just make sure to right click and choose "Run as Administrator" when you install the Lagarith codec and Install both the 32 bit and 64 bit version of Lagarith. Record at 1280x720 at 60 fps, and also make sure to render the movie in Sony Vegas at 29.97 fps. If you still get lag when recording your game, chances are that your computer is not very fast, so a smart thing to do would be to have your movie capture to a storage drive. To do this, simply find some old hard drive and connect it to your mother board and then right click on the drive and choose "Format" so it is wiped clean, then create a new folder on the drive called "DXtory Movies" and then tell DXtory to use that folder as a capture destination for all of your recorded movies. You can test the "Write Speed" in DXtory and see for yourself that it will write to the storage drive much faster when recording. And if you are still getting lag in your game when recording, then you should download the Packbit codec from the DXtory website and use that instead of Lagarith. The Packbit Codec is lossless like Lagarith, but it can record movies at an insane max resolution of 16384 x 16384 using RGB24 - and it can do it fast! Lagarith is very tiny and weak in comparison to Packbit. Just remember to use XVid MiniConvert to convert your avi to XVid before attempting to open it in Sony Vegas.
