DV tape capture audio conversion issues with Hybrid

[mcb7]

I have captured a number of DV tapes using my Macbook Air via the firewire interface and I am wanting to convert/compress them into mp4 files to share online. I have copied the files to my Windows PC and have tried using Hybrid with default settings to convert them but I am getting an issue with the audio.

The audio seems to be stretching out to double the length of the original clip. If I do the conversion without audio the video file is the correct length but if I add audio, the file runs for twice the length but the video is running at normal speed but stops halfway through and the audio is running half speed.

Is there some settings I can change to fix this?

TIA

If the videos play well in your PC after you copy them, then perhaps Hybrid is not the best software to do the conversion.
Try to test a different one like HD Video Converter they have free trial to use. You need to convert *.mov to *.mp4 , right?

[mcb7]

Yes the videos play fine on the PC. I’ll have a look at HD Video Converter but as I’ve got hours of video to convert I was wanting something free.

HD Video Converter (WonderFox HD Video Converter Factory) is not only a converter but also a great downloader.
I think I paid only $10-$15 for it with discount few years ago.
But first thing try it and see if it is good for you.

Handbrake. It's free and does batching.

You should have captured your DVCAM tapes into DV-AVI not .mov, Not a lot of software can work with that weird format especially when the audio is 32Khz/12bit. If you can re-transfer your tapes you can avoid few lossy conversions.

[Cornucopia]

Except, capturing via a Mac, the container will almost ALWAYS be mov (or its cousin mp4), because that is the native format of the OS.
( Certain pro proprietary systems can cap to DV in mxf, and systems based on ffmpeg could conceivably use other formats).

Yes, that's why Mac is not recommended for this kind of tasks, It's a closed ecosystem, It requires everyone on the planet to have a Mac to be issue free.

That's not necessary. All they want to do is convert DV to MP4. I'll bet there's dozens of converter programs that will do it. And they're not doing "few lossy conversions".

I gave up on Hybrid. The interface is complex and there was always something in a nook and cranny somewhere that tripped up what I was trying to do. In the right hands it's probably good but it is not user-friendly.
