Hi longshanks

I wrote this reply earlier, maybe you missed that post.

Hi

VS12 is limited in what it can set for Project Properties, your only options are AVI or Mpeg, you should use Mpeg
I would set those the same as your final Mpeg2 video file which will be used to burn a DVD.

MPEG files
24 bits, 720 x 576, 25 fps
Upper Field First
(DVD-PAL), 16:9
Video data rate: 8000 kbps (upto 70 minutes project)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

When you complete the editing
Share – Create video File – same as project properties (top option)
If you have created your own template, it is available at the bottom of that list.
If your project is longer than 60 minutes (70max) then you will have to reduce the Data rate below 8000kbps to reduce the file size below 4.3 Gb to fit to disc.

Maybe we are getting ahead of ourselves, you have to prove that re-naming to Mov does work for you?

I had quality problems using Format Factory so good to know the Mov rename trick does the job.
I rendered the sample to mpeg2, uploaded to DropBox here:-

Mpeg2 v mp4

You should use your camera to record Mpeg2 for future work.
Mpeg2 is more suitable to burn a DVD
mp4 for upload to internet


the quality of using Mpeg2 compared to mp4 should be better when burning a disc.

and the small icon
Smart Proxy file has been created for that clip, view Tools - Smart Proxy File Manager

[Longshanks]

Ok thanks. I was going back to your earlier post about using template manager etc.

Re smart proxy indicator- I guess I don't have worry about this? Again, never seen this before so assume must be connected to status of these former MP4 files now re-designated??

I'll get on with it tonight and let you know how I get on.

Many thanks for your time, expertise and patience

Hi

High Definition video can be demanding on our pc’s capability causing playback issues, by creating these proxy files does smooth playback making editing easier.
Files will be automatically created for any file with a frame rate over 720 x 576.
Now that VS12 can read the mov file its frame video size being seen as 1047 x 576 is activating Smart Proxy.
By the way for VS12 SmartProxy is enabled by default.

Proxy files are quite large so once you have completed the project remember to delete those files.
If your hard drive is small you may wish to disable Smart Proxy?

For details….View Tools Smart Proxy Manager or press f6 for preferences – Smart Proxy tab

Ok thanks again.

Hi

Just on way home to try project again but have two questions which have been bugging me.

1. Why did I not get the message about using same project properties when I put .mov clips into timeline? (despite selecting that option) Is it something to do with the change of file extension?

2. When I changed from MP4 to .mov did that inherently change file properties? I was wondering whether the ones I posted yesterday were native MP4 or somehow altered ones?

Thanks

1. Why did I not get the message about using same project properties when I put .mov clips into timeline? (despite selecting that option) Is it something to do with the change of file extension?

Yes. Even the most recent versions of VS will not show a message when a first .mov clip is inserted into the timeline. Don't know why -- Corel just never wrote it into the code, I guess.

2. When I changed from MP4 to .mov did that inherently change file properties? I was wondering whether the ones I posted yesterday were native MP4 or somehow altered ones?

No -- the only thing that was changed was the extension... and its effect on the Show Message process.

Thanks Ken

Hi again

Just wanted to inform that I followed advice to letter re project settings and rendering mpeg 2 file.

Rendered video file looks fine but still no sound when played from preview window or when added to create disk prior to final tweaks, menu etc (this was problem with previously converted mpeg files). As per before there is sound when said mpeg is dropped into timeline on the edit tab of VS12.

Is this to be expected?

I'm in work right now but will post video properties later.

Thanks

Hi Longshanks

I did not have any reason to place the mpeg on the timeline, I was happy that the mov file could be imported to VS12 and a Mpeg2 file created.
That file played from the library (clip mode) and my media players.

So yes there is a problem with project playback but only with VS12.
I have also tried rendering to LPCM, Mpeg2 Layer1 and Digital Dolby audio with the same problems for VS12.

I think it is the original mp4 audio that VS 12does not like.

I tried creating a wav file of the mov, that crashed the program????

I am also having problems using the file in CVSX9.

I was also unable to convert to a good quality video file using Format Factory that would import to VS12

Clearly Video Studio just does not like this mp4 format.

All in all the mp4 is quite troublesome.

Playing Mpeg2 made in VS12 play ok in CVSX9 in project and cl;ip mode.


I have said earlier that mp4 video is not suitable for burning a disc and you should record using Mpeg.

Your existing project and final output Mpeg2 should burn to disc and play on your DVD player.

But for future camera recordings you should use mpeg format.

I have asked, why don’t you record to Mpeg2?

[Longshanks]

Hi

Thanks for quick response. I have also said previously that I did not "consciously" record using mp4. This happened by default, so to speak by me selecting the long play option in Cam. I don't know why this was the case. I thought first that this was due to saving to Cam HDD rather than sd but that evidently not the case-more to do with video choice in Cam (xp, sp and lp).

I have also stated that, knowing more about this protocol, I can record mpeg2 format.

This is therefore, a legacy problem, so to speak, for this project.

Thanks again.

[Longshanks]

Decided to go ahead and burn mepg 2 to dvd to test and audio works fine. Plays on pc and dvd player.

Will ensure that I use option that records to mpeg 2 rather than mp4.

Many thanks for all your help.

Hi

Thanks for the feedback, good to know the disc worked ok.

I’m still a little confused as to why we cannot create any video of any type from the mp4 that plays audio correctly in VS, don’t like mysteries
