SVP13.0-video imports as all green & has sound but no waveform

sensory wrote on 6/6/2018, 12:13 AM

Hello,

90% of the time, i am sent videos in this format: (it's my first time with mediaInfo so not sure if I have the right info for you).:

This is chapter 1 of 17, which is also very common - usually up to 25 chapters.

I want the whole thing rendered into one piece so that closed-captioning is easier. When I import this into svp13.0 I get a totally green preview pic, and I can hear sound however there is no waveform (I really need the waveform for captioning).

The way I get around this is to run this video through handbrake and I end up with an mp4 file that VEgas can read. I do this with all 17 chapters, then I join all 17 chapters together using VEgas, then I close caption. Then I burn captions in (another render).

Can someone please tell me how to get these 17 chapters to join together in one hit and what program to use (paid or otherwise). This system is way too laborious and long.

thank you.

Load em in VideoRedo, use the Joiner function and they will be done in minutes instead of hours. There is a free trial. For all it's features, Vegas isn't an AVC muxer.

Are you sent .mov files? Do you know how they are generated?

In Mediainfo select View / Text and post. That view gives much more information about your source files.

NickHope I will look at the link you posted now. These videos come from schools where they have it within their internal digtital libraries however it is not captioned. They send it to me zipped and it comes to me like this, or similar. Either way, I can rarely drop it straight into vegas or if I can & the footage comes through 'like normal', then i find the audio is a touch out of sync - certainly enough to be very annoying.

Okay, here are the properties once it has been dropped into vegas (i.e. green monitor and flat sound wave).

The vertical resolution of 576 indicates that the files probably started out as interlaced PAL files. It's anyone's guess how they would have been converted to MP4.

One thing you could try is bypassing compoundplug.dll so that the files get decoded by mcmp4plug2.dll. See part 7 of this: https://www.vegascreativesoftware.info/us/forum/faq-why-won-t-vegas-open-my-file-correctly-codecs-converters-etc--104572/

Another thing to try would be a straight re-wrap of the file in FFmpeg to see if that fixes anything in the file structure. That's in part 9 of the same post. You would replace ".mkv" in that ffmpeg command to ".mp4". There is a little more help on ffmpeg use (for a different purpose) in this post: https://www.vegascreativesoftware.info/us/forum/faq-how-to-convert-mov-video-e-g-iphone-to-mp4-for-vegas-pro--106154/

If you're allowed to share a sample (e.g. on Dropbox, Google Drive, OneDrive, mega.nz, wetransfer.com or mediafire.com), others could test it and try solutions.

I would expect it to open in every version of Vegas. However, as Nick says, we don't know how it began life.

My guess is that the school is recording over the air broadcasts (legally) and dumping a crippled transport stream into a new container.

If playing the mp4 works in VLC, sanitize it in VideoRedo free trial and I bet it will work in Vegas.

Hi music vid, way too late for me to make too much sense but can i just say that yes, definately legally copied. We are schools that are allowed to copy from free to air tv but unfortunately (for me) it’s not until the teacher has a deaf student that they realise the legal ramifications of not providing an accessible version ( i,e. Captioned) . I then become under immense stress to provide captions pronto. So no doubt it has come from copied version but their libraries are all slightly different and invariably, vegas does not convert. I end up relying on handbrake & a system i know to be laborious and flawed, but the only one i know due to lack of I. T. Knowledge. I feel caught between ‘a rock and a hard place’ due to not understanding how to fix it. Will follow your advice (& others). Thanks so much.

It's ironic that Over The Air Broadcasts (I'm in the US) likely had the captions embedded in the streams.

[SWAG from way out on the end of the limb]

The clips might have been recorded by a device like this that converts to AVC/AAC on the fly.

[/SWAG from way out on the end of the limb]

Anyway, VideoReDo is likely a good place to start.

Musicvid wrote on 6/7/2018, 11:11 AM

If it was recorded over the air, then it is a transport stream and riddled with internal errors by definition. Vegas and every other NLE hates this. You will never know it from the sanitized mp4 properties, but it is still not a friendly program stream.

If it works in a player and not in Vegas, download the Videredo trial. This is not trivial advice or speculation, because it works most of the time. Do let us know how it works out...

Yes, extremely ironic. If i know the broadcast is coming up, I will record it with captions in-tact. however, if they provide the footage to me, it is often too late and has gone through too many processes for me to extract anything. Unless you can advise otherwise? If they are the original 'recorder' of the footage, what format should I ask for to try and access captions as you have above? I presume you are choosing 'promote closed captioning' (something like that). when I try that I get nothing. How can I tell from the footage if they are hidden in there?

"If they are the original 'recorder' of the footage, what format should I ask for to try and access captions as you have above?"

If you could get them to do what you asked, you should ask that they use devices that record the whole transport stream. I use a very old program called Beyond TV 4 by Snapstream Media. They no longer sell the program as they have gone into a server-based line of business to record OTA broadcasts for archive and compliance purposes. The tuners that I use (This One and the older version of This One) just detect the stream and passes it to the program unaltered from its MPEG-2 format with all the content as in tact as you will see it from a broadcast sent 50 miles over the air. A typical broadcast looks like this:

There is an Internal Vegas setting that determines whether captions are scanned. I always make it a point to turn off scanning since I never do anything with them. In fact, I rarely edit broadcast TV in Vegas since I have a whole system available to watch the recorded output and I have too much camera video that I need to work on first.

After using VideoReDo Quickstream Fix to repair stream errors output to MPEG-2 Program Stream (.mpg). Vegas apparently doesn't like transport streams (.ts) and won't display the captions. Even if yo can't promote them and handle them programmatically, you can see the text on the Vegas timeline and see where they go.

Before requesting any further support, please say Yes it did work or No it did not work.

If you are making a feature request to add robust Muxing and CC engines to the Vegas footprint, I can say this is the wrong way to go about it.

I've been having an irritating feeling this thread had taken on a familiar ring on a couple of items -- difficulty mastering subtitles and indifference to established third party solutions. Doctor shopping?

Your next step will be to share a short original sample via fileshare. You are entitled to do this under fair use doctrine, since your 3 remaining responders won't be uploading it to yt or fb.

The video now works after running it through Video Redo.

It took a while because i am in this office 3-days per week and the link was blocked by my employer. I had to wait for I.T. to remotely download it to my computer.

Apologies if I was 'doctor-shopping' , I didn't know there was such a thing. I was asking questions as they were popping up (I guess because I was waiting for the download).

I realise now, that's not the correct thing to do.

No malice intended.

This issue is sorted. Thank you all for your help.

And it's really annoying to give freely of ones time and get ignored, as if you didn't believe the diagnosis. Twice.

The link that musicvid provided is the same information I was going to give. Good luck!

Just a perspective; glad we were able to lead you to a solution.

Here's to a new normal going forward. Welcome to the forums!
