Is this a true dv avi captured file? Via virtualvcr with fusion gold t 3

[yoda313]

I was wondering if this a true dv-avi capture. I used virtual vcr because my fusion hdtv gold t 3 capture card is a wdm driver card and won't show up properly in virtualdub.

The drivers provided with the card do not offer direct avi recording (similar to the hauppauge 250,350 series - hardware mpeg encoding card with hdtv tuner).

Here are the stats via gspot:

So is the correct? I used the panasonic dvsd codec. This is from a vhs capture over svideo output from a panasonic dmres46v vhs-dvd recorder player combo unit.

Here is a screenshot:

It is from the movie SPHERE (mods please let me know if you want me to remove the picture of the movie - thanks - do own the official copy on vhs so this is a personal backup).

Should this be the ideal method I should take for vhs captures from now on? Capturing in dv-avi then making any edits and encoding to mpeg2 from there? I know it will be more work but should I do this to ensure a better end result?

Also:

How can I choose a lower bitrate pcm encoding option? In virtualvcr when I choose 48khz pcm audio it only gives 768kpbs as a low bitrate - the other is the 15xx bitrate option. Even though I'll be recording in stereo I think 768 is overkill and will require unneccessary downconversion to 448kpbs or lower for dvd bitrate. (even though I'll probably end up converting to ac3 to save space).

Also is there are way to get a free ac3 encoder to capture directly to ac3 448 or 348? It will be stereo but it will at least save one conversion step.

Thanks.

Edit - I did look up ac3acm in the tools section for ac3 encoding. However in virtual vcr I can set 448kpbs as the bitrate but it says theres an error and resets it to a default. It then records in 192kpbs. The quality is ok as it is just a stereo source (analog from vhs) but why would it not allow a higher bitrate?

pcm is not compressed so you should use the standard ~1500kbps 48khtz setting. it looks like it's DVavi. check with mediainfo and see if the video bitrate is ~25000kbps.

Yes it does have that bitrate - here:

Actually I have since downloaded ac3acmdecompressor so I can encode to ac3 directly. However for some reason I can only encode to 192kpbs in virtualvcr. It does not let me record at 384kpbs or 448kpbs. Is this a limit of the encoder or a virtualvcr limit?

if you are going to use the video in an nle i'd stay with pcm. it will allow for fast easy editing using a DVavi template and then after you are done editing convert to ac-3.

Thanks aedipuss.

I'm not sure what app I'll be editing with. Right now I'm just planning on snipping commercials out and stuff like that. Most likely it will be virtualdub with direct stream copy for no reencoding during cutting.

I have already experimented with avstodvd for dvd creation from the avi files. It works perfectly. Very smooth and easy. That will save the extra step of loading into tmpgenc dvd author. If I want a more robust menu I can simply output without a menu from avstodvd and then load into tmpgenc dvd author.

Thanks again.
