quickstream fix question

I had an issue with a file from off a TV recording (cable went wonky during the recording)
I was able to bring it up using the quickstream fix feature.

In the past, the recordings were always MPEG 2 and quickstream seemed to do an intelligent recode and things moved very quickly (like 5 minutes).
Over the past year, comcast has switched over the vast majority of channels to H.264, so when I went to so a quickstream fix, it did a full RECODE and it took close to an hour.

question:

if I know ahead of time that the file is H.264, can quickstream output be switched over to H.264 so it remains an intelligent recode?
If so, where do I make that switch?

Thanks in advance

Easy! Here is what works for me. Make a special profile like this:-

1. In Tools->EditOutputProfiles, select a generic profile such as "MPEG-2 Transport Stream".
2. Click "Copy and Edit" to bring up an editor for that profile, then make the following changes:-
3. Change "Encoding type" to be "Match Source".
4. Change the "Profile name" to something such as "Transport Stream Match Source".
5. Click OK to return to the list of profiles. Your new profile will be at the bottom of the list.
6. Move it to the top of the list, and tick it. Now it will be the default profile selected by QSF.

No BluRay in v6 sorry. It's just not a highly requested feature and the expense/time required to add it just isn't something we think is worth it.

No official time frame. We're close to being done with all the big features we wanted to add, but there is likely still going to be a long alpha/beta cycle before it goes live. It's all been a lot more than we expected.

I get the lack of demand. For the longest time, I was burning discs left and right. Once thumb drives came down in price, I moved to that. Now, with 5Ghz Wifi running 80211 ac, I don't even need those for in-house viewing. A friend of mine recently wanted something I had and needed it on a blu-ray. I had to go back and re-familiarize myself with just how to to it.

That's kind of the consensus we're seeing. We get an occasional request for BD burning, but it's pretty rare. The licenses and development effort involved with adding BD support just aren't worth it in our opinion.

In v6 all of the default profiles will use "Match Source" so you wont have to deal with this manually.
Hi Dan,

I finally bought VRD without waiting for V6. :love:

I have a question related to the "Match Source" parameter. I searched in the help, but did not find anything. I want to use VRD to cut commercials from movie recordings without loss of quality (frame accurate on H.264 encoding). So I think that H264 Transport Stream profile is the one I want to choose. By default, the output mode is "Intelligent Recode" which seems to be OK (and the Encoding Type is H264/AVC).

Question: what is the different between "Encoding Type = H264/AVC + Output Mode = Intelligent Recode" and "Encoding Type = March Source"?

Thanks in advance! :)

"Match Source" will always change the output type to match the file type you load into VRD.

"Intelligent Recode" will try to not recode the output if possile.

Certain changes you make WILL trigger a Recode.
Other changes you might make like changing the compression (HD to SD)
will require you to set a "force recode" or nothing will change.

When you go to "save" you will see a "Major Recode Required" displayed
in the "save" window if VRD is going to recode the file.

Thanks.
So if I understand correctly, if I load a H.264 TS from my recording and I select "Match Source", it is like selecting "H.264+Intelligent Recode" (if no "Major Recode" modifications)?

Yes to above.

But you would have "match source" set first when you don't want changes.
So that all the files you load will not change the file type output from the "type" input.

The "last used" setting would be for when you are recoding a lot of file types...say .mpg to H264.mp4
and the H264.mp4 output would stay until you changed to outputting to .TS, now the .TS would stay...etc.

OK, it is clear. I will make a new profile for my recordings: H.264 TS with "Match Source" by default, as recommended.
Thanks jmc!

Match source just allows you to use a single profile for any input format and still get intelligent output. If you set a specific codec, like H.264, and use that profile for a source file that is not H.264 then the output will always be recoded to H.264. This wasn't a big issue in v5 because we really only supported two input types (MPEG-2 and H.264), but in v6 we're also adding H.265 so it became exponentially more unwieldy so we decided to make all the profiles Match Source by default. But you can still create codec specific profiles if you want.

I also record raw h264/TS files from Comcast and have Fast Recode hiccup on occassion. I will edit segments, then go to output and VRD will demand to do a full recode.
If I click on "Profile Options" then close the dialog without doing anything, VRD decides it doesn't need to do a full recode after all.

A minor bug, quick and easy to work around, but not something you'd intuitively think of.
