Cross Fade for edits and cuts

I have been using pinnacle studio 12 to edit movies I record off my hauppauge pvr 1600. Pinnacle just seems to crash to much and cause problems. I really do like how fast I can edit using it though and I really like that I can drop 2 sec crossfades onto all my cuts making a very smooth transition without having to zoom down to the frames to make super precise cuts.

In any case, video redo seems to be much more stable and reliable and after playing with the trial version I feel I've got the hang of the program pretty well and am able to edit my movies, etc just as fast as I could with pinnacle studio 12. However, the one thing I miss is the crossfades. Now I know, crossfades require rendering and video redo doesn't render (that I know of) it copies to new files leaving out the cut segments. Which is awesome.

So to add a simple crossfade feature would make this program 10 stars for me, and I do realize that adding such a feature is probably not very easy to do.

To the developers: maybe you could have video redo just render the transitions and then insert those transition clips between the cuts?

I would pay more for such a feature as video redo is solid and reliable.

I hear ya, but honestly it seems like one of the most basic things that a lot of people would expect. Sometimes your recordings don't end well and a fade to black would help. Also, I've noticed when using a 2 sec cross fade between clips you get an almost unnoticeable transition between commercials. As opposed to every commercial it fades to black and then back up.

Otherwise great work on a solid program!

I've mentioned this before, but our biggest problem with any kind of fading is the audio. VRD does not include an AC3 encoder, which means that if you added any kind of fade effect to a video with AC3 then the audio would either not fade with the video, which could be weird, or we would have to recode the entire audio stream as MP2, which would be undesirable.

For it to work seamlessly we'd have to add AC3 encoding support. Unfortunately, due to licensing fees, that would cause the price of VRD to jump more then we're comfortable with so it's not something we want to do right now. There have been internal discussions of add-ons or multiple versions of VRD with different features, but if anything like that is going to happen it's probably a ways off as we're currently focused on our next release with H.264 support.

Well that makes sense to me, thanks for explaining.

Do most movies that your record off cable tv have ac3 audio?

For instance I have a hauppauge 1600 that records tv shows and movies at a high bit rate. How do I know if its recording in ac3?

ohh, and just out of curiosity, what would it cost for that license?

I would donate money to this as a project and Im sure many others would too as you guys have got such a good fan base!

Alot of us, not necessarily me, have money for expensive home theater gear and have extra money that we would consider putting towards something like this...

Most digital cable and HD content is broadcast with AC3 audio, so this affects a lot of content. Not sure about your Hauppauge card, but if it records ATSC or QAM then yes it will most likely effect you as well.

You have to sign an NDA to get license prices from Dolby, so I can't disclose that sorry.

So why not just fade the video? You have an option to save as mpv, just have fade in or out keeping the same length of the file. We can then add the audio back without loosing sync., this would certainly be helpful to some of us.
Or just give it as an option on mpg video/audio, not everyone uses AC3 audio.

I know this thread has been dead for a few months now, but I wish to add my 2 cents. Currently, I use VR TVS for editing my home movies from my Handycam. It works great, I love the fast frame copy and the loss-less editing provided by VR. Sometimes I need to stitch several short videos together. currently, my only option for this is my Sony Vegas software - if I want to add fades for a smoother transition between different scenes.

For the most basic editing and for a quick and dirty scene stitch, this is all I am doing. Vegas doesn't even have very good AC3 support, so I am having to rip the audio out as AC3 and then add it back in as part of my final process (whether it's using FFMPEG to generate an FLV file or DVD Architect to create a DVD). I don't have a problem editing the audio and adding the audio-fades in Vegas or Nero, then exporting the AC3 file and rejoining it later to the video. My main problem is that Vegas needs to re-encode the entire video (which is already DVD-Compliant video) when adding just a few short fades. This takes a process that could be 2 minutes and stretches it out to a 10 minute encode.

I would much prefer to have the option to fade the video in VR. The assumption I'm making is that only the faded scense would need to be re-encoded, while the majority of the video would be fast-frame copied, preserving the original quality and speeding up the process.

I would like to have the option to add some transitions to my videos, even if it is Video only or without AC3 support.

As far as AC3 licensing... I have learned that in the world of software licensing, if you have to ask how much it costs, then you can't afford it. :) The NDA is so they can protect their right to charge whatever they want based on the size of the product. In the same way that enterprise level software costs Company A with 250 employees $80,000 and Company B with 2500 employees would pay $500,000, even though they both receive the exact same software.

Thanks for the great work, love the product! I even suggested that my company look into providing our customers with VR (we are a video based company).
